Ibrahim El-Shenawy Ghounim, Mohammed Raafat Mustafa, Ibrahim Hmmam

Hort. Sci. (Prague), 2022, 49(4):213-224 | DOI: 10.17221/112/2021-HORTSCI

The mango (Mangifera indica L.) is a common tropical and subtropical fruit and the second main fruit crop in Egypt. In this work, start codon targeted (SCoT) and inter simple sequence repeat (ISSR) markers were employed to study the genetic relationship among twenty-three mango genotypes grown under the El-Giza district conditions. These genotypes consist of four newly introduced cultivars, six new progenies and thirteen closely related mango cultivars which were included as cultivar references for the best definition. Based on the overall SCoT and ISSR data, a total of 52 bands were generated (18 for SCoT and 34 for ISSR) with a total polymorphic percentage equal to 53.84% (44.44% for SCoT and 58.82% for ISSR). Based on the whole set of SCoT and ISSR marker data, the genetic similarity coefficients ranged from 80 to 97% with a mean equal to 88.5% and the first two principal axes explained about 31% of the total genetic variation among the mango accessions. The SCoT and ISSR data revealed that the four newly introduced mango genotypes, namely 'Aya', 'Kasturi', 'Maya' and 'Omer', are novel genetic resources based on their genetic profiles, which can be used for future breeding programmes in Egypt.

The suitability of macadamia trees for different climates has been shown to affect tree growth and fruit quality. In this study, the differences in tree survival rate after frost injury, tree growth, nut mass, kernel quality and yield of seven macadamia cultivars were evaluated for field production in the high altitude and high latitude climate of southern Tibet, and the suitability of macadamia cultivars was determined. The cultivars evaluated were ‘Beaumont’ (‘HAES695’), ‘HVA16’ (‘A16’), ‘Hinde’ (‘H2’), ‘Own Choice’ (‘O.C.’), ‘SSCRI-1’, ‘SSCRI-2’ and ‘SSCRI-3’. Of these, ‘Beaumont’, ‘A16’, ‘H2’ and ‘O.C.’ were Australian cultivars and ‘SSCRI-1’, ‘SSCRI-2’ and ‘SSCRI-3’ were Chinese cultivars. The results showed that all seven cultivars grew well under the high altitude and high latitude climate conditions of southern Tibet without continuous frost. ‘A16’ and ‘Beaumont’ in addition to their reasonable yield, nut mass and kernel quality, had the higher tree survival rate after frost injury. ‘A16’ and ‘Beaumont’ were well adapted to the high altitude and high latitude climate of southern Tibet, followed by ‘O.C.’, ‘SSCRI-1’ and ‘SSCRI-2’, but ‘SSCRI-3’ and ‘H2’ were unsuitable. These results indicated that it is possible to produce macadamia in the high altitude and high latitude climate of southern Tibet by planting excellent frost-resistant cultivars, with promising yields and a commercial standard of nut quality.

Soil & Water Res., 2026, 21(1):1-8 | DOI: 10.17221/143/2025-SWR

In this study, we present a detailed geochemical characterisation and stable isotope systematics of silver (Ag) in a mining waste facility at the Namib Lead & Zinc mine in Namibia (Africa). We examined a series of flotation tailings and ore minerals to address two principal questions: (1) the distribution, chemical form and leachability of Ag, and (2) the local Ag isotopic signature(s) and its variability in relation to Ag speciation in the solid phase, as well as the fate of stable Ag isotopes. Our findings reveal a significant correlation between Ag and Pb concentrations, indicating that galena is the primary Ag carrier. Most importantly, all mild extractions mobilised only a minimal amount of Ag (≤ 1 wt.% of the total amount). This suggests that most Ag is associated with geochemically stable phases, specifically sulphides, which are not subjected to leaching and/or intensive weathering. Unlike other isotope studies, the present research demonstrates a homogeneous Ag isotopic signal in the tailings and individual ore samples with an average δ109Ag value of ~ 0‰ (± 0.1, 2SD). Therefore, this study provides new knowledge and clearly supports the use of Ag isotopic data to track primary Ag sources globally, not only in Africa.

Crislayne Teodoro Vasques, Nicolas Bueno Mordhost Zeraik, Claudia Cirineo Ferreira Monteiro, Antonio Roberto Giriboni Monteiro

Czech J. Food Sci., 2026, 44(1):45-51 | DOI: 10.17221/46/2025-CJFS

High salt (sodium chloride) consumption is a significant public health concern worldwide. There is strong scientific evidence that a high-sodium diet is associated with increased rates of several health problems. This article aims to replace the salt content of sliced bread with salt encapsulated in xanthan gum, providing a non-homogeneous distribution of salt to maintain the perception of salty taste. The key focus of this research is to maintain the product's sensory characteristics and ensure consumer acceptance, a crucial aspect in the success of any food product. For this purpose, three sliced bread formulations were developed and compared: Formulation 1 (F1) as the standard, and Formulations 2 (F2) and 3 (F3) using the encapsulated salt technique, with respective reductions of 30% and 50% in salt. Physicochemical analyses were performed on the products of the three bread formulations. Sensory analysis was also performed on the products from the three bread formulations, involving 80 untrained tasters, to evaluate and compare salt intensity. Thus, it was evaluated that F1 and F2 did not present statistical differences in the sodium content, while F3 presented a difference between the others. Therefore, it was possible to conclude that reducing sodium by 29% using xanthan gum encapsulation can be an alternative to reducing salt without lowering flavour perception.

This study investigated the effects of temperature on the performance of anaerobic digesters for biogas production. Digesters were filled with a 1 : 1 ratio of substrate to water, containing 15 kg of cow dung and 3 kg of crop waste, and maintained at temperatures of 50 ± 2 °C and 30 ± 2 °C, corresponding to the thermophilic and mesophilic biodigesters, respectively. The experiments run for 75 days, and biogas production rate and purity were measured. The thermophilic digester produced 48.4% more biogas and had a slightly higher pH (7.65) than did the mesophilic digester (7.37) by the end of the observation period. However, gas chromatography revealed that the CH4 and CO2 contents did not significantly differ between the two treatments. The CH4 concentration in the mesophilic environment was 42 ± 10%, whereas that in the thermophilic environment was 53.5 ± 10%. The CO2 composition was 32.5 ± 1% and 35.5 ± 1% for the mesophilic and thermophilic setups, respectively. These were supported by the wavelength (460 nm to 620 nm) of the flame colour, indicating that the biogas from both setups is predominantly composed of methane. In conclusion, thermophilic anaerobic digesters may have a relatively high biogas production rate, but the biogas purity is not significantly different from that of mesophilic digesters.

Michaela Kulišťáková, Eva Sobotková, Radek Filipčík

Czech J. Anim. Sci., 2025, 70(3):83-92 | DOI: 10.17221/8/2025-CJAS

The aim of this study was to analyse the conformation traits and body dimensions of Haflinger mares registered in the Czech Republic studbook. The study focused on the effects of age at studbook entry, year of birth, proportion of Arabian genes, and country of origin on various parameters. Data were collected from 825 mares, including scores obtained during the studbook entry evaluation and body measurements such as withers height measured with a stick (WHS), withers height measured with a tape (WHT), chest girth (CG), and cannon bone circumference (CBC). Based on these data, the bone index (BI) and body massiveness index (MI) were calculated. Statistical analysis was performed using multifactor analysis of variance (ANOVA) and Scheffe’s post-hoc testing method. The results showed that the age at studbook entry significantly affected conformation scores, chest girth, cannon bone circumference, and both indices (MI, BI). Mares aged 3–4 years had significantly higher conformation scores compared to mares aged 5–6 years (P = 0.001) and mares aged 7 years and older (P = 0.000). Mares aged 5–6 years and those aged 7 years and older showed higher CG values (P = 0.002, P = 0.000) and CBC values (P = 0.010, P = 0.001). Furthermore, the year of birth had a highly significant impact on all variables studied. The withers height of mares born between 2011 and 2020 was, on average, 3.49 cm higher (144.84 cm) than that of mares born between 1987 and 2000 (141.35 cm) (P < 0.000). Regarding CG, a statistically significant increase was observed in mares born in 1987–2000 and 2001–2010, with chest girth increasing from 180.45 cm to 183.76 cm (P = 0.016). However, a subsequent decrease to 179.91 cm was noted in mares born between 2011 and 2020 (P = 0.002). The influence of the proportion of Arabian genes was significant for WHS, where mares with a higher proportion of Arabian genes (>1.56%) showed lower WHS (141.74 cm) compared to mares with a lower proportion (143.86 cm) or no Arabian genes (143.01 cm). While ANOVA demonstrated a significant effect of Arabian genes on CBC, Scheffe’s post-hoc test did not confirm this finding. No statistically significant differences were observed in other body dimensions based on the proportion of Arabian genes. The influence of the country of origin was statistically significant for all variables except WHS and WHT. Regarding the conformation scores, mares from the Czech Republic scored lower (6.98) than Austrian mares (7.22, P = 0.000). Additionally, CG was significantly lower in Austrian mares (178.58 cm) compared to Czech mares (182.54 cm, P = 0.000). Austrian mares also had significantly lower MI (P = 0.000) and BI (P = 0.040), with Austrian indices at 124.71/13.31 and Czech indices at 127.77/13.41. Based on this empirical evaluation of the current and original population of Haflingers in the Czech Republic, the connections and influence of individual factors during breeding are revealed. The results of our analysis have built an objective scientific basis and they allow the breeding organisation to determine the further breeding process.

Cucumber anthracnose is a destructive fungal disease caused by Colletotrichum orbiculare. Common control strategies include chemical fungicides. However, this can lead to the development of pathogenic resistance. Therefore, it is necessary to identify natural compounds or microorganisms to develop new chemicals and the biological control of fungal pathogens. Isolate GT2, a bacterial isolate from soil samples collected in Shimane Prefecture, Japan, significantly inhibited in vitro mycelial growth and conidial germination of C. orbiculare, indicating a fungicidal effect against this pathogen. Furthermore, anthracnose lesion formation was significantly suppressed without phytotoxicity when cucumber leaves were pretreated with a cell culture suspension of the isolate GT2 before inoculation with C. orbiculare. Bioautography of the culture filtrate (CF) of the isolate GT2 using thin-layer chromatography showed that the compound inhibiting C. orbiculare growth had an Rf value of 0.38. The effective compound in GT2-CF was ethyl acetate insoluble and heat-stable at 121 °C and has a molecular weight larger than 1 000 Da. In conclusion, Paenibacillus polymyxa GT2 demonstrated the potential for developing a new fungicide and biological agent against anthracnose disease caused by C. orbiculare.

In a contemporary globalised world, assuring food security in the conditions of developing a food self-sufficient economic structure represents not only a challenge in terms of the changing agricultural paradigm, but also an important instrument in assuring, in a long-term manner, societal resilience. However, while achieving self-sufficiency in food, China still faces challenges in terms of establishing sustainable food security and transitioning to a zero hunger state. Rapid economic growth and urbanisation have resulted in shifting food consumption patterns from crops towards more nutritious meat and dairy products and higher-qualitative imported foods. In this study, the current state of food security and production and trade in food and agricultural products in China during 2000-2020 have been analysed and an overview of the strategic directions of the domestic sustainable development, food security, and zero hunger policies are highlighted. The main aim of the study is dedicated to identifying the critical shortcomings and gaps in combating hunger and food insecurity in China and proposing policy recommendations regarding improving the stability of the food supply in the country and deigning new possible strategies to achieve it. The results highlight the major trends and shifts of the food security paradigm in the process of developing a food self-sufficient economy.

Plant Soil Environ., 2022, 68(12):580-590 | DOI: 10.17221/294/2022-PSE

The ameliorative effects and its mitigation mechanisms of selenium (Se) on cadmium (Cd) toxicity in cucumber seedlings were studied through hydroponic experiments. Cd and other mineral nutrient concentrations, antioxidant enzyme activities, and antioxidant contents in cucumber were studied. The results revealed that exogenous Se significantly decreased the Cd concentrations in all tissues, especially in the leaves. Moreover, exogenous Se (Cd + Se) could increase Zn, Na, leaf Cu, stem/root Fe, stem/root Ca, and stem/root Mg concentrations; and reduce leaf Mg concentration, compared with Cd alone treatment. Additionally, the application of Se ameliorated the toxicity of Cd by harmonising the activities of antioxidase, such as Cd + Se treatment reduced Cd-induced increase of superoxide dismutase, glutathione peroxidase, leaf/stem ascorbate peroxidase (APX) activities, which resulted in the significant decrease of the content of hydrogen peroxide, and malondialdialdehyde; increased root APX, and glutathione reductase activities. In addition, the content of nonenzymatic antioxidants such as root-reduced glutathione and oxidised glutathione was significantly increased by adding Se under Cd stress. Also, exogenous Se enhanced the total antioxidant capacity in terms of cupric-reducing antioxidant capacity and decreased total phenols, flavonoids, and leaf/root proline contents under Cd stress. In general, 3 μmol/L Se was conducive to plant growth and improved the cucumber's ability to alleviate Cd stress.

J. For. Sci., 2022, 68(5):170-181 | DOI: 10.17221/29/2022-JFS

Seedling quality is an important input affecting the outplanted seedling performance. Morphological attributes and association with symbiotic ectomycorrhizal (ECM) fungi belong to influential traits determining seedling quality. In this study, the effect of pre-sowing applied commercial additives Ectovit (containing hydrogel and ECM fungi), Mycorrhizaroots (ECM fungi and nutrients) and Vetozen (natural mineral fertilizer) on the growth and ectomycorrhiza formation of Norway spruce seedlings grown in nutrient-poor pure peat in an open nursery site was assessed. Two-year-old bareroot seedlings were transplanted into containers. No significant growth differences were detected between treatments for 1 + 0 seedlings but the values of growth parameters (root collar diameter; stem height; shoot, root and total dry weight) of Ectovit-inoculated seedlings were significantly higher than those in the other treatments including the control after the second (2 + 0 seedlings) and the third growing season (2 + 1). Root-to-shoot dry weight ratio and number of root tips were distinctly higher after the third year compared to the previous two years but they were not significantly different between treatments. Mycorrhizaroots and Vetozen did not have any significant effect on seedling development. Although the occurrence of treatment-specific ECM morphotype was detected in Ectovit-inoculated seedlings, the high total ECM colonization of roots in all treatments including the control indicated a crucial impact of naturally occurring fungi on ectomycorrhiza formation.

Czech J. Anim. Sci., 2026, 71(1):1-10 | DOI: 10.17221/138/2025-CJAS


Autochthonous cattle breeds represent important resources of genetic diversity. The Busha cattle breed is reared in the Balkan Peninsula and is characterised by high adaptability, resilience, longevity, small body size, and low maintenance and production requirements. During the 36-year observation period, the total population of the autochthonous Busha cattle breed in the Republic of Croatia amounted to 10 411 animals. Pedigree completeness for the total population, considering the first parental generation, was 97.1%. The average inbreeding coefficient was 2.44%, ranging from zero to 42.6%, while the average relatedness coefficient was 3.56% in the total population. The effective population size, calculated in the reference population based on the individual increase in inbreeding, was 63.3. The probabilities of gene origin in the reference population were fe – 38.0, fa – 33.0, and fg – 25.4, indicating a loss of genetic variability due to genetic drift (fg/fe – 0.66) and a bottleneck (fe/fa – 1.15). In the population of the autochthonous Busha cattle breed, the effective number of ancestors (fa) was smaller than the effective number of founders (fe). Increased relatedness among animals was observed, which could affect the long-term conservation of the population.

Caraway (Carum carvi L.) is an economically important spice and medicinal crop valued for its essential oil composition, particularly its high content of carvone and limonene. Despite its commercial relevance, compared with that of other Apiaceae species, the development of genomic resources remains limited. Molecular research has progressed from early dominant marker systems, including random amplified polymorphic DNA (RAPD) and inter simple sequence repeat (ISSR), to more recent SNP-based genotyping approaches that clarify population structure and flowering-type differentiation. However, key genomic resources, such as simple sequence repeat (SSR) markers, a high-quality reference genome, quantitative trait locus (QTL) mapping, genome-wide association studies (GWAS), and transcriptomic datasets, are still lacking. This review synthesises current knowledge on molecular marker applications in caraway and identifies major gaps limiting breeding progress. Evidence from related Apiaceae species indicates that systematic SSR development and integration of genome-based tools can substantially enhance breeding efficiency. Particular emphasis is placed on a phased strategy for SSR development in caraway, positioned as complementary to single-nucleotide polymorphism (SNP)-based approaches within a progressive genome-enabled breeding framework. Strengthening the molecular infrastructure of caraway will support precision breeding aimed at improving yield stability, essential oil quality, and environmental adaptability.

Subsidies and farming: A microempirical analysis of financial allocation to promote agricultural productionOriginal Paper

Congxian He, Lulu Yu, Huwei Wen

Agric. Econ. - Czech, 2026, 72(3):156-170 | DOI: 10.17221/187/2025-AGRICECON

Agriculture's stable development is vital to the national economy, and its vulnerability justifies fiscal support. On the basis of data from the China Family Panel Studies from 2012 to 2022, this study examines how fiscal allocation affects agricultural production, particularly rural households' grain-growing enthusiasm and their productive income. Results show that public expenditure significantly boosts agricultural production, supported by ordered probit and ordinary least squares fixed effect models and confirmed in robustness tests. Mechanistic tests indicate that agricultural public expenditure promotes agricultural production by improving agricultural technical levels, enhancing production services, and expanding the agricultural scale. Heterogeneity analysis shows that agricultural public expenditure has a stronger effect on grain-growing enthusiasm among low-educated rural households and on productive income in major grain production areas. It also has a stronger effect on productive income for rural households with emerging and prime-aged farmers, in nonmajor grain production areas, and those with high educational attainment. The research offers empirical insights for exploring ways to achieve the 'dual goals' of food security and poverty alleviation.

Marina Jovanović, Petar Vojvodić, Marija Petrović, Danka Radić, Dragana Mitić-Ćulafić, Marija Kostić, Sonja Veljović

Czech J. Food Sci., 2022, 40(6):456-464 | DOI: 10.17221/164/2022-CJFS

This study aimed to produce yogurt with Ganoderma lucidum residues and selected probiotic bacteria. To select the most potent GABA-producing strain (GABA - γ-aminobutyric acid), nine probiotic bacteria were subjected to the glutamate decarboxylase (GAD) activity assay. Limosilactobacillus reuteri DSM 17938 was selected and used in preparing fresh yogurts, with and without supplementation of Ganoderma residues obtained after water extraction [GW (Ganoderma waste) 2% (w/v)]. A decrease in pH during fermentation and the occurrence of syneresis were investigated. Lactic acid bacteria (LAB) viability and anti-Escherichia activity were estimated. Further, the cytotoxic effect of yogurt extracts on the human colon cancer cell line (HCT116) was surveyed. Besides functionality, the sensory attributes were evaluated. The pH values did not significantly change with the GW addition while increasing the LAB counts [up to 9.76 ± 0.11 log colony-forming units (CFU) mL-1] and the cytotoxic effect on HCT116 cells. Yogurt produced with selected bacteria and GW had the most valuable anti-coli effect against E. coli 0157: H7 and E. coli ATCC 35218 (American Type Culture Collection, Rockville, Maryland) (4.81 ± 0.62 and 5.64 ± 0.29 CFU mL-1, respectively). Although the added GW increased the yogurt functionality, it had a slightly negative effect on the taste and texture of the partially modified recipe. Yogurts fortified with GABA-producing strain and GW could potentially reduce relapse rates of depressive disorders.

Juglans pyriformis Liebm. (Juglandaceae) is a threatened and endemic tree that grows in the cloud forest of Mexico. Natural populations of this species have been reduced due to, among others, changes in land use, overexploitation, and logging, with probable effects on its genetic diversity and structure. To determine the levels of variation and genetic structure of two populations with different silvicultural regimes, six inter-simple sequence repeat (ISSR) primers were used to amplify DNA from 35 individuals from a high-logging population and 32 from a low-logging population. The results show a higher polymorphism in the low-logging population (81.5%) compared to the high-logging population (77.4%). The genetic differentiation coefficient (PhiPT) values (0.109), genetic distance (0.134) and STRUCTURE analysis (Fst = 0.2271, P = 0.04) show significant genetic differentiation between populations. Rare, private, and monomorphic bands were detected in both populations. These results confirm the trend of reduced genetic variation due to logging.

Czech J. Food Sci., 2026, 44(1):35-44 | DOI: 10.17221/190/2024-CJFS

Pumpkin seeds and their oil cake are often treated as by-products, but their composition and high nutritive and biological value makes them a promising material for nutritional enrichment of bakery products. The purpose of this study was to characterise pumpkin seed flour (PSF) and pumpkin seed oil cake flour (PSOCF), and evaluate the effects of their addition on the chemical composition including the fatty acid composition, textural parameters, sensorial characteristics and antioxidant activity of the wheat bread. Six experimental bread samples with 5, 10 and 15% of PSF or PSOCF added to wheat basic formulation, and a control wheat sample, were produced. Results indicated that addition of PSF and PSOCF led to higher ash, cellulose, protein, fat, total carotene and unsaturated fats content, which means that the experimental bread samples had a higher nutritional value. PSF addition had more positive effect on the textural characteristics and antioxidant activity of bread, than PSOCF addition. All bread samples (evaluated by 5-point scale multiplied with the coefficient of importance) had very high sensory quality (89.88–96.59% of maximal possible quality). The results confirmed that PSF and PSOCF are suitable for use in food industry for nutritional enrichment of wheat bread and related products.

Evaluation of changes in dry matter and nutrient content during the growth dynamics of silage maizeOriginal Paper

Czech J. Anim. Sci., 2026, 71(3):129-139 | DOI: 10.17221/172/2025-CJAS

The aim of this study was to identify and quantify the relationships between the nutrient content and the DM (dry matter) content of various maize hybrids (Zea mays L.) in the dynamics of vegetative maturity and various soil-climatic growing conditions. Over the course of 7 growing seasons (years), a set of 1 972 samples of whole silage maize plants consisting of 206 different hybrids grown in two contrasting regions (lowland and foothill areas) was analysed. The focus was on DM content and the content of key energy nutrients (WSC – water soluble carbohydrates, starch, NDF – neutral detergent fibre) and their interactions. Results show that the transformation of WSC into starch has four key points: (i) it begins at a DM content of 150 g/kg; (ii) it peaks at a DM content of approximately 235 g/kg; (iii) it begins to decrease significantly from a DM content of 300 g/kg; and (iv) it practically stops rapidly after exceeding a DM content of 350 g/kg. In the dynamics of vegetative development of maize plants, the DM content is very closely related to the WSC content (R2 = 0.728) and the starch content (R2 = 0.873). With the gradual increase in vegetative maturity and DM content in maize plants, the transformation of WSC into starch dynamically increases. These characteristics, with small deviations, were also confirmed at different levels of evaluation (all analyses, regions, seasons and individual hybrids). These results show that a DM content of 300 g/kg to 350 g/kg can be considered the optimal harvesting window for maize ensiling and the optimal phase of silage maturity for whole maize plants, because once the DM content exceeds 350 g/kg; the transformation of WSC into starch stops and the drying phase of plants begins.

Azadirachtin as a sustainable tool for zero pesticide residue production: Residue dissipation in open-field tomato productionOriginal Paper

The growing demand for vegetables free from pesticide residues has fuelled the search for sustainable pest management solutions. This study assessed the efficacy of azadirachtin, a neem-derived biopesticide, in achieving no detectable pesticide residues in tomato production under open-field conditions. The experiment, conducted from April to September 2024, included a systematic application and residue analysis using liquid chromatography-mass spectrometry (LC-MS). The results showed that azadirachtin degraded rapidly, with residual levels in leaves, green fruits, and mature fruits falling below the detection threshold (0.01 mg/kg) after 8–10 days following treatment. The statistical analysis revealed strong time-dependent residue dissipation, with little systemic buildup in fruit tissues. The findings suggest that azadirachtin is a viable, environmentally friendly alternative to synthetic pesticides, aligning with food safety requirements and customer preferences for pesticide residue-free fruit. Future research should investigate the ecological factors that affect degradation rates to optimise its application in diverse agro-climatic conditions.

This study was conducted to investigate the effect of Lactobacillus zeae LB2 on the gut microbiota in piglets infected with enterotoxigenic Escherichia coli (ETEC). Thirty-two healthy 7-day-old piglets were randomly divided into four treatment groups: control group (basal diet), LB2 group (supplemented with 1 × 108 CFU/pig/day L. zeae LB2), ETEC group (infected with 1 × 1010 CFU/pig/day ETEC) and ETEC+LB2 group (LB2 supplementation + ETEC infection). Intestinal contents were collected for DNA extraction and Illumina sequencing. Significant result was observed for alpha diversity in the four intestinal sections, and both ETEC infection and LB2 supplementation showed a higher Chao1 alpha diversity. At the phylum level, Firmicutes and Bacteroidetes were dominant in the healthy piglets, while Proteobacteria were dominant in the ETEC-infected piglets. At the genus level, ETEC infection decreased the abundance of Prevotella, Ruminococcaceae, Lactobacillus, Alloprevotella, Flavobacterium, and Sutterella and increased the abundance of Actinobacillus. The LB2 supplementation reduced the abundance of Ruminococcaceae, Actinobacillus, Porphyromonas, and Alloprevotella, and increased the abundance of Prevotella and Lactobacillus. Both ETEC infection and LB2 supplementation affected several functional pathways associated with cellular processes, environmental information processing, genetic information processing, diseases, metabolism, and organismal systems. In summary, ETEC infection induced dysbiosis of the gut microbiome in piglets, while L. zeae supplementation could positively regulate the gut microbiome during ETEC infection. Therefore, L. zeae LB2 may be an ideal probiotic for the prevention or treatment of ETEC infection.

Phytoplasma-like symptoms of leaf yellowing and calyx malformation were observed in eggplant (Solanum melongena L.), upward leaves and fruit malformation in pepper (Capsicum annuum L.), and aerial tuber formation in potato (S. tuberosum L.) during the survey performed in the late season (August to September) of 2015 and 2016 in Van province (Turkey). A total of 100 samples were tested by nested-PCR using universal primer pairs to assess the sanitary status of the solanaceous crops and to characterise the phytoplasma isolates. Among them, seven samples resulted in a 1.25 kb DNA fragment, and five (two eggplants, two peppers, and one potato) were molecularly characterised (Accession No.: KY579357, KT595210, MF564267, MF564266, and MH683601). BLAST and the virtual restriction fragment length polymorphism (RFLP) analysis of 16S rRNA genes revealed the presence of two distinct phytoplasma infections in solanaceous crops: 'Candidatus Phytoplasma trifolii' a member of the clover proliferation group (16SrVI) and subgroup A and 'Candidatus P. solani' a member of the stolbur group (16SrXII) and subgroup A. The virtual RFLP analysis and calculated coefficients of RFLP pattern similarities further revealed a remarkable genetic diversity among the 'Candidatus P. solani' isolates infecting pepper (similarity coefficient of 0.90) and eggplant (similarity coefficients of 0.98 and 1.00) at the same geographical area. This is the first report of the natural occurrence of 'Candidadtus P. trifolii' in potato from the Eastern Anatolia region, Turkey.

Feed efficiency (FE) is one of the most essential traits in dairy cattle, primarily due to the high cost of feed, which constitutes a significant portion of dairy herd expenses. Unfortunately, assessing FE in individual cows requires precise measurement of feed consumption, a labour-intensive and expensive process that is impractical for group-fed cows on production farms. Efforts have been made to predict FE or, more precisely, dry matter intake (DMI), using predictors such as a body weight (BW), milk yield (MY), and milk composition. Recently, Fourier transform mid-infrared (FT-MIR) spectroscopy has been proposed as a tool to enhance the accuracy of DMI prediction. This paper reviews the application of FT-MIR milk spectroscopy for deriving FE phenotype in dairy cattle. FT-MIR is a reliable and widely used method for routine analysis of milk components. In FE phenotyping, predictive equations often incorporate FT-MIR alongside other traits such as BW, MY, milk composition, herd, breed, days in milk, and pregnancy. The most commonly used mathematical approaches are partial least squares (PLS) regression and artificial neural networks (ANN). Prediction accuracy varies across studies, depending on the mathematical method and model employed. Predictions based solely on FT-MIR data have demonstrated moderate accuracy (coefficient of determination), ranging from 0.19 to 0.40. However, integrating all data sources including MY, milk composition, FT-MIR, and near-infrared reflectance spectroscopy (NIR) is crucial and results in higher accuracy, with reported values ranging from 0.03 to 0.81.

Hort. Sci. (Prague), 2022, 49(4):225-233 | DOI: 10.17221/108/2021-HORTSCI

Many studies have demonstrated that arbuscular mycorrhizal fungi (AMF) and deficit irrigation (DI) have positive effects on the fruit yield or quality. This study aims to test whether the watermelon sugar content and yield can be improved by appropriate amounts of AMF and DI methods and to clarify the underlying physiological mechanism. Diploid and triploid watermelon cultivars and their pumpkin rootstock-grafted seedlings were treated with AMF, DI and DI + AMF in a randomised complete block design with five replications. The results showed that DI significantly reduced the relative water content (RWC), PN, alkaline α-galactosidase activity, but increased the insoluble acid invertase (IAI), sucrose synthase (SuSy) and sucrose phosphate synthase (SPS) activities compared with the well-watered (WW) treatment, which led to a decrease in the fruit yield and an increase in the fruit sugar content. Although the AMF improved the RWC, PN and alkaline α-galactosidase, IAI, SuSy and SPS activities in all the watermelon lines under both the DI and WW conditions, the improvement magnitude of these parameters was more pronounced in the pumpkin-root watermelon lines than the corresponding own-root watermelon lines, especially under the DI condition. The integrated application of AMF and DI increased the fruit yield to a level similar to the WW value in the pumpkin-root watermelon lines and sugar content to an optimal level in all the watermelon lines.

Ascochyta blight, caused by a complex of pathogenic fungi including Didymella pinodes, Ascochyta pisi, and Phoma pinodella, is a major disease of field pea (Pisum sativum), causing severe losses through lesions on leaves, stems, and pods. Mutation breeding using gamma irradiation is a non-GMO strategy to induce genetic variation and accelerate the development of improved genotypes. In this study, the M2 generation of the forage pea cultivar Dodoni (Pisum sativum L. var. arvense), derived from M0 seeds irradiated with 100 Gy, was evaluated for tolerance to D. pinodes (CBS 251.47) using a detached-leaf assay under controlled greenhouse conditions. Disease progression was quantified via image-based analysis on the 3rd and 5th days post-infection, calculating diseased area and disease severity index. Extensive phenotypic evaluation was also conducted on 16 families in the greenhouse and 100 families under field conditions, using an augmented incomplete block design. Screening revealed several M2 families with significantly improved tolerance compared to non-irradiated controls. Among these, some individuals combined enhanced resistance with improved yield-related traits, such as higher pod number and biomass, while others exhibited reduced agronomic performance. These findings highlight the phenotypic diversity induced by gamma irradiation and demonstrate the potential to generate dual-purpose pea genotypes with both disease resistance and enhanced productivity, providing valuable material for future breeding of resilient cultivars.

Forests play a significant role for maintaining the biodiversity. In order to manage sustainable forests, tree species history, distribution, and their future prospects are vital. Using standardized quantitative approaches, the age, radial growth, and size class distribution of Abies pindrow (Himalayan fir) were determined from three different altitudinal sites (i.e. high, middle, and lower). The results indicate that Himalayan fir growing in the high-altitude site (Ayubia, 2 917 m a.s.l.) of moist temperate forests of the Himalayan mountains showed lower radial growth (0.13 cm) than in the middle (Bara Gali, 2 617 m a.s.l.; radial growth = 0.13 cm) and lower (Kuldana, 2 455 m a.s.l.; radial growth = 0.22 cm) altitude sites. Correlation analysis demonstrated that age showed a significant positive correlation (P < 0.001) with diameter at breast height. The tree-ring width chronology (totally 80 core samples) of Himalayan fir was developed from moist temperate forests of Himalayan mountains of Pakistan. At Ayubia site it possesses a long time-span (1703-2020 C.E.), followed by Bara Gali (1862-2020 C.E.) and Kuldana (1864-2020 C.E.). Further, the tree-ring width (TRW) chronology of Ayubia showed a significant positive correlation (P < 0.05) with May and June temperature, and a significant negative correlation (P < 0.05) with June and October precipitation, indicating that summer temperatures are the key factor for the radial growth of Himalayan fir. For the Kuldana site, the response of TRW chronology to temperature and precipitation was the same, however, it was significant only for June temperature at Bara Gali. The size class distribution of the high-altitude region (Ayubia) showed a higher number of individuals than the lower altitude region, indicating the lowest disturbance conditions. The absence of individuals in the early size classes and the gap in middle and mature size classes indicate a lower regeneration potential and anthropogenic impact. The pointer year analysis indicated that the Bara Gali forest is more sensitive to abnormal climate events than the other sites. Based on the present study, we suggest that proper attention and conservation strategy should be provided to Himalayan fir growing in the moist temperate forests of Pakistan.

This study investigated the response of sago palms to saline conditions, focusing on their morphological and photosynthetic performance. The photosynthetic traits were evaluated using OJIP chlorophyll fluorescence transient. The plants were exposed to a saline condition of 224 mM NaCl, and their ability to form associations with arbuscular mycorrhizal fungi (AMF) was also assessed. We tested both commercial AMF products, containing spores from multiple genera, and isolated AMF spores from Glomus etunicatum and Glomus grape, to determine their ability to infect sago palm roots under high salt conditions. The results showed that sago palms can maintain efficient photosynthesis even at high salt levels. This is likely due to their ability to prevent excessive salt uptake in shoots and water loss from roots by forming lignin deposits in cell tissues. Furthermore, the study found that sago palm roots can form associations with AMF under saline conditions. These findings indicate that sago palms exhibit tolerance to saline environments, making them a promising crop option for areas with low soil quality where other carbohydrate-producing crops cannot tolerate the conditions.

Rainfall is a major contributor to water erosion of sloping cropland in Northeast China. Identifying how rainfall and slope gradient (S) influence runoff depth (RD) and sediment yield (SY) is crucial for preventing water erosion. Field measurements from runoff plots were collected from 2023 to 2024, and K-means clustering was applied to clarify the rainfall patterns. Response of RD and SY to the rainfall pattern and S were analysed. Key factors impacting RD and SY were explored. The results showed that three rainfall patterns were identified for 34 erosive rainfall events: A (41.2%, medium duration, medium rainfall intensity, and medium rainfall amount (RA)). B (50.0%, short duration, high rainfall intensity, and low RA) and C (5.4%, long duration, low rainfall intensity, high RA). Furthermore, the cumulative RD and SY increased with S for the same rainfall pattern. The cumulative RD and SY responded similarly to rainfall patterns for the same S. The contribution of the rainfall pattern to the cumulative RD and SY decreased in the order of C, A, and B. In addition, rainfall duration (D) and maximum 30-minute rainfall intensity were the key factors affecting RD and SY for rainfall pattern A, respectively. Rainfall erosivity (R) was the key factor affecting RD and SY for rainfall pattern B and C. R and RD were the dominant factors influencing the RD and SY for all rainfall events, respectively.

The wheat seed gall nematode Anguina tritici is a scientifically interesting nematode due to its aerial parasitic behaviour and ability to survive for years under desiccated conditions in seed galls. However, Anguina's life cycle and its correlation with host-plant growth and environment are poorly understood. Here, we conducted a microplot study at IARI, New Delhi, India, to examine the effects of early and late sowing dates on the life cycle of the wheat seed gall nematode using growing degree days (GDD). The study confirmed the presence of juvenile stages in the soft, undifferentiated floral mass and the upper one-third part of the stem. During the early stage of floral differentiation, the plant ovary develops into milky grains, while the galls (false ovules) become fully green. An increase in size and gonad cell development was observed when nematode J2S entered the floral tissue. The count of adult females in galls marginally surpasses that of adult males, and the female: male ratio ranged from 1.46 : 1.00 to 1.48 : 1.00. After GDD and cGDD (cumulative growing degree days) calculation, we found that the nematode completed its life cycle in 90 to 140 days, depending on the wheat sowing dates and change in temperature. The study also showed that nematode development was in sync with wheat plant growth and development. The information developed from the study such as the cumulative GDD and it's correlation with Anguina's life cycle, presence of nematode in stem, flower and gall, it's migration from collar to flower, presence of various stages of nematode in different plant tissues, and it's undergoing the anhydrobiotic process in seed galls may be used to determine the best time to intervene and manage nematode infestations.

Organic seed coating is an alternative method for supporting sustainable agriculture. This study investigates the influence of organic coating and seed storability on cucumber seeds using atmosphere-controlling techniques. The seeds were coated with an organic formulation, and a non-coated seed was used as a control. All samples were then packed using modified atmosphere packaging, including normal air, 100% N2, and 100% CO2, and stored under ambient conditions (30 ± 2 °C) for 8 months. Results indicated that the organic seed coating did not significantly affect seed germination compared to the non-coated seeds (> 0.05) throughout the storage period. Moreover, the coating tended to positively influence seedling growth, including root and shoot lengths, seedling growth rate, chlorophyll content, and total phenolic content. Additionally, seeds packed with 100% CO2 showed a slight impact on seedling growth compared to those in normal airbags, but this modified atmosphere packaging technique tended to increase chlorophyll a and b, as well as the total phenolic content in seedlings. Conversely, seeds packaged with 100% N2 tended to decrease seedling lengths. Therefore, cucumber seeds coated with an organic formulation and packed in a 100% CO2 bag can enhance seedling growth parameters during germination and extend seed storability.

Due to the length of egg-laying period (> 80 days), two applications of insecticides against cabbage stem weevil (Ceutorhynchus pallidactylus Marsh.) are currently needed. However, resistance of pollen beetle (Brassicogethes aeneus F.) to pyrethroids complicates the choice of suitable insecticide for the second application. The active ingredients cypermethrin, etofenprox, pymetrozine, indoxacarb and chlorpyrifos-ethyl applied as second spring applications to winter oilseed rape crops were assessed under field conditions from 2016 to 2018 to ascertain how they could reinforce the effects of the first spring application (beta-cyfluthrin) on cabbage stem weevil. Chlorpyrifos-ethyl and etofenprox strengthened the effects of the first spring spray on cabbage stem weevil markedly more than cypermethrin. Pymetrozine and indoxacarb, effective on resistant populations of pollen beetles, showed the lowest contribution to increase the effects. Indoxacarb showed a low effect on C. pallidactylus in laboratory tests too. The impacts of the bans on active ingredients chlorpyrifos-ethyl and pymetrozine are discussed.

General resilience in dairy cows: A reviewReview

Eva Kašná, Ludmila Zavadilová, Jan Vařeka, Jitka Kyselová

Czech J. Anim. Sci., 2022, 67(12):475-482 | DOI: 10.17221/149/2022-CJAS

Dairy farming is deeply affected by climate change, especially by rising temperatures and heat waves, poorer availability of quality food and water, and the spread of new diseases and pests outside their original ecological niche. Their impact can be mitigated not only by changes in technologies, management and treatment, but also by breeding and selection of more resilient cows. General resilience encompasses the animal's capacity to cope with environmental, social and disease challenges. It is described as the capacity of the animal to be minimally affected by a disturbance or to rapidly return to the physiological, behavioural, cognitive, health, affective and production states that pertained before exposure to a disturbance. As disturbances can be of different natures, general resilience is a composite trait consisting of different resilience types according to the nature of the disturbance. Resilience can be quantified through time series data that capture fluctuations in the daily performance. Recent studies have worked with deviations in the daily milk yield and daily live weight from optimal performance or have focused on the assessment of the daily activity in terms of the daily step count. To observe the duration and magnitude of the response to perturbance, two indicators were suggested: the autocorrelation (rauto) and the natural logarithm of deviations (LnVar). Based on the daily milk yield deviations, both indicators have shown sufficient genetic variabilities with the estimated heritability ~0.1 for rauto and ~0.2 for LnVar. Low values of both indicators were genetically related to better udder health, better hoof health, better longevity, better fertility, higher body condition score, less ketosis but also lower milk yield level. The selection for improved resilience could benefit from the use of genomic information as several genes and biological pathways associated with disease resilience and resilience to heat stress have already been identified. The presented results suggest that the integration of resilience into the cattle breeding programmes would improve the capacity of the dairy industry to cope with global climate change.
