Effect of long-term storage on the change in the expression of selected Mal d 1 gene isoforms in the apple cultivar Opal®Original PaperIvona ®ïárská, Radek ÈmejlaCzech J. Genet. Plant Breed., 2023, 59(3):141-147 | DOI: 10.17221/102/2022-CJGPB Apples are available all year round since they can be stored for long time. However, the expression of the major apple allergen Mal d 1 can increase in the fruit during storage and incease so the risk of allergies in sensitive consumers. Therefore, we studied the change in the expression of the Mal d 1 gene during storage in the modern cultivar UEB 32642 (known under the brand name Opal®) and the cultivar Gala Brookfield (cv. Gala) as a reference. The cultivars were stored under two different conditions, ultra-low oxygen (ULO) and standard cold conditions. The gene expression was evaluated both in fresh fruits and in fruits stored for four, six, and nine months. Nine isoforms of the gene Mal d 1 with the highest published expression were quantified using real-time PCR. The most expressed isoforms Mal d 1.01, Mal d 1.02 and Mal d 1.06A were found in the fresh and also in the stored fruits. The expression of the Mal d 1.03G and Mal d 1.06D isoforms was higher the sored fruits. Our study confirmed that (i) Opal® had a lower overall expression of the Mal d 1 gene than cv. Gala, both in the fresh and stored fruits; (ii) standard cold storage is superior in preserving lower Mal d 1 levels in Opal®apples compared to the ULO conditions; and (iii) less expressed isoforms may be responsible for the general increase in the Mal d 1 gene expression during storage. |
Complete chloroplast genome sequence and characteristics analysis of Qingda no.1 alfalfa (Medicago sativa L. cv. Qingda no.1)Original PaperYuling Ren, Yajun Ma, Xue Li, Xiaoan Li, Guozhu Yang, Ping LiCzech J. Genet. Plant Breed., 2023, 59(3):160-168 | DOI: 10.17221/71/2022-CJGPB Medicago sativa is the most widely cultivated forage legume and one of the most economically valuable crops throughout the world. Qingda no.1 (Medicago sativa L. cv. Qingda no.1) is an excellent alfalfa local variety with strong cold, drought and salt resistance in the three rivers source area of Qinghai. In this study, the whole chloroplast (cp) genome of Qingda no.1 was sequenced, assembled and its structure was analysed by the Illumina high-throughput sequencing technology. The results showed that the chloroplast genome of Qingda no.1 exhibits no obvious typical quadripartite structure; the total length of the chloroplast genome is 125 637 bp; the chloroplast genome contained 111 genes, including 77 protein-coding genes, 30 tRNA genes, and 4 rRNA genes, with an overall GC content of 38.33%. The relative synonymous codon usage showed that 68.67% of the codons RSCU > 1 in Qingda no.1, with the preference ending with A and T. The simple sequence repeat (SSR) analysis identified 62 SSR loci. The phylogenetic analysis of the cp genome, Qingda no.1 clustered closely with Medicago sativa KU321683 (Medicago sativa L. cv. KU321683). These results are helpful for the further study of the Qingda no.1 adaptation mechanism to high altitude stress environments. |
Inheritance and allelism of brown midrib trait introgressed in agronomically promising backgrounds in pearl millet (Pennisetum glaucum (L.) R. Br.)Original PaperShashi Kumar Gupta*, Ponnaiah GovintharajCzech J. Genet. Plant Breed., 2023, 59(3):176-187 | DOI: 10.17221/93/2022-CJGPB The lignin content of forage crops significantly affects the livestock’s forage intake and its dry matter digestibility. The brown midrib (bmr) trait is known for its association with a reduced lignin content and increased digestibility. Pearl millet inbreds having the bmr trait were derived from two populations ICMV bmr and WRajPop bmr via continued selfing up to 6–8 generations. The results from the crosses revealed the presence of the same single recessive gene that controlled the bmr in both the populations. The stable expression of the bmr gene in the new genetic background indicated that there was no effect of modifier genes. Four inbreds were identified with the stable expression of bmr (three in ICMV 155 and one in the WRajPop background) with a high biomass potential, which can serve as a bmr source in future pearl millet forage breeding programmes. |

Effects of dietary protease supplementation on behaviour, slaughter performance, meat quality and immune organ indices of broilersOriginal PaperXixi Li, Xinxin Wang, Yi Lv, Wenfeng Ma, Xiaohong Wu, Wenrui Zhen, Furong ZhaoCzech J. Anim. Sci., 2023, 68(6):255-265 | DOI: 10.17221/178/2022-CJAS This study was conducted to investigate the effects of protease supplementation on the behaviour, slaughter performance, meat quality, and immune organ indices of broilers. A total of 240 one-day-old Arbor Acres broiler chickens were randomly allocated to four treatments, with six replicates per treatment and 10 broilers per replicate. Chickens were fed corn-soybean meal basal diets supplemented with 0, 4, 8, and 12 IU/g of protease. Compared with 0 IU/g of protease supplementation, 12 IU/g of protease increased the average and minimum time of feeding and drinking behaviour (P < 0.05); increased the average, maximum, and minimum time of preening behaviour (P < 0.05); and decreased feeding, walking, and stretching frequency (P < 0.05). pH24h of breast and thigh muscles had improved (P < 0.05). The shear force of the breast muscle and the cooking loss of the thigh muscle had decreased (P < 0.05). Compared with 0 IU/g of protease, 4 IU/g of protease increased the average and minimum time of lying behaviour (P < 0.05) and decreased stretching, scratching, and aggressive frequency (P < 0.05). The shear force of the thigh muscle and spleen index had enhanced (P < 0.05). Protease can be used as an additive in a broiler diet for production. |
Effect of urea and molasses supplementation on in vitro digestibility, feed quality of mixed forage silagesOriginal PaperEsra Gürsoy, Gürkan Sezmiº, Ali KayaCzech J. Anim. Sci., 2023, 68(6):266-276 | DOI: 10.17221/212/2022-CJAS This study aims to investigate using different ratios of urea-molasses in silage of food in vitro fermentation, feed value and quality production in feed. After being withered a little, the fodder plant was fragmented into 2–3 cm long pieces. 0, 2 and 4% molasses and 0, 0.5 and 1% urea were added. The treatment groups were UM1 (control), UM2, UM3, UM4, UM5, UM6, UM7, UM8 and UM9 supplemented with 0, 0, 0, 1, 1, 1, 1.5, 1.5, 1.5% urea and 0, 2, 4, 0, 2, 4, 0, 2, 4% molasses respectively, and a total of 54 silage samples, 9 × 6 parallel, were prepared, vacuumed in ready-made silage bags, and stored at 25 ± 2 °C for 60 days. After the silages were opened, pH, nutrient contents, Fleig scores (FS), in vitro digestibility parameters, energy contents, feed value and feed quality were determined, then the data were subjected to analysis of variance. The effects of urea and molasses additives added to the mixed forage plant silage on all parameters were found to be significant (P < 0.05, P < 0.01). The crude protein (CP) increased its application by UM7. Cell wall component (insoluble fibre in acid detergent (ADF) and neutral detergent insoluble fibre NDF) reduced its application by UM9. All these applications increased the FS. The addition of molasses increased the in vitro gas production, while the addition of urea decreased the production. True organic matter digestibility increased with the addition of molasses. As a result, it was concluded that UM9 application in silages would be appropriate for increasing feed value and feed quality, and the UM3 application in silage would be appropriate for improving true organic matter digestibility (TOMD). |

Effects of drought stress on carbon metabolism of bermudagrass (Cynodon dactylon L.)Original PaperYilong Zhang, Yuxuan Bao, Peiying Li, Qikun Yu, Wen Li, Lisi Tang, Xiaofan Sun, Zongjiu Sun, Shuo LiPlant Soil Environ., 2023, 69(6):269-281 | DOI: 10.17221/426/2022-PSE The effect of drought stress on carbon metabolism in the leaves and roots of bermudagrass was investigated. Plants established in PVC tubes suffered from three water treatments for 10 days. C138 and Tifway (drought-tolerant) were found to have lower relative electrical conductivity and higher water use efficiency than C32 (drought-sensitive) under moderate drought by increasing carotenoid and soluble sugar content and rapidly decreasing leaf starch content. The sucrose synthase activity of leaves and roots, acid invertase and neutral invertase activity of C32 roots substantially decreased under severe drought, resulting in a slow sucrose decomposition rate and significantly lower fructose and glucose contents than C138 and Tifway. The activities of four carbon metabolism enzymes and sucrose content in the leaves were greater than those in the roots, while the fructose and glucose contents were on the contrary, indicating that bermudagrass transported fructose and glucose obtained from sucrose decomposition from leaves to roots under drought to reduce roots damage. The path analysis indicated that leaves neutral invertase activity, and roots soluble sugar content might be the key parameter of carbon metabolism in bermudagrass under drought. |
Distribution of soil macroarthropods in differently using land parts of tropical rainforest Padang, IndonesiaOriginal PaperFenky Marsandi, Hermansah, Hidayatul Fajri, Wawan SujarwoPlant Soil Environ., 2023, 69(6):291-301 | DOI: 10.17221/389/2022-PSE Soil macroarthropods, as a component of the soil community, directly feel the impact of land use changes. Not only the density but understanding the soil macroarthropods distribution pattern will help in providing an insight into the quality of soil health. The sampling process was carried out using the pitfall trap methods on the forest, logged forest areas, mixed gardens, and monoculture gardens in the tropical rainforest of Bukit Pinang-Pinang Padang, Indonesia. The results showed that the forest as a natural habitat supported the density of soil macroarthropods among other land use types. The density in the forest, logged forest area, mixed garden, and monoculture garden sequentially is about 20.29, 13.18, 15.2 and 12.21 indv/m2. The presence frequency high value of soil macroarthropods was found in the forest, and for some soil macroarthropods, such as Hymenoptera, Diptera, and Araneits, the importance value increases when their habitat is disturbed. The fertile soil in intensive monoculture gardens does not support the individuals’ total number, types, and density of soil macroarthropods. On the other side, the dominant soil macroarthropods prefer disturbed soil conditions and will decrease their presence frequency if chemical compounds are introduced into the soil. Land use change in the Bukit Pinang-Pinang tropical rainforest area causes changes in the distribution pattern of soil macroarthropods. The changing tendency of distribution patterns in fragmented habitats is due to nutrient availability, limited resources and land treatment. Habitat fragmentation affects not only the abundance and density of individuals and types of soil macroarthropods but also the distribution pattern, which not only threatens their existence and the environment but also has the potential to regenerate. |
The use of modern fermentation techniques in the production of traditional wheat breadOriginal PaperPavel Skøivan, Marcela Sluková, Ivan ©vec, Helena Èí¾ková, Iveta Horsáková, Eli¹ka RezkováCzech J. Food Sci., 2023, 41(3):173-181 | DOI: 10.17221/39/2023-CJFS A traditional Czech bakery white bread product is commonly made with directly mixed dough with the addition of yeast. In order to be able to reduce the salt content of the final product without compromising its acceptability to consumers, the dough was prepared with the addition of pre-ferments and wheat sourdoughs. The aim was to deepen the flavour background of the product and thus have a positive effect on its sensory properties. Wheat sourdoughs were prepared and tested using starter cultures and matured under different conditions. The resulting products were tested both sensorially and by means of precise physical methods. |

The effects of COVID-19 crisis on small family farms: Empirical evidence from Visegrad countriesOriginal PaperIvana Bla¾ková, Veronika Svato¹ová, Gabriela Chmelíková, Vojtìch Tamá¹, Eli¹ka Svobodová, Libor Grega, Simona Mi¹kolci, Jakub Piecuch, Apolka UAgric. Econ. - Czech, 2023, 69(9):366-374 | DOI: 10.17221/217/2023-AGRICECON This paper aims to investigate the effects of the COVID-19 crisis on small family farms in Visegrad countries and to provide evidence of how they have responded and coped with the crisis. We conducted our investigation using an exploratory qualitative research design based on 86 semistructured in-depth interviews with owners or responsible managers, and explored the effects of the COVID-19 pandemic on different areas of their businesses, such as human resources, supplier-customer relations, production, distribution channels or strategies, price of inputs and outputs and business models. Our findings showed that small family farms have been resilient in the face of the COVID-19 pandemic. Several negative impacts were identified, such as a decrease in sales due to the closure of accommodation and restaurant services, delays in the supply of inputs, and minor problems with the availability of workers, but those were perceived to be moderate. However, the COVID-19 pandemic created not only difficult challenges but also opportunities for small farms. Based on our findings, three main recommendations regarding the adaptability and resilience of family farms in Visegrad countries have been formulated: i) the importance of a diversification strategy, ii) selling through short supply chains, and iii) digitalisation of agriculture. |

The cytochrome P450 gene GhCYP94C1 is involved in drought stress in upland cotton (Gossypium hirsutum L.)Original PaperLijiao Gu, Pengyun Chen, Shuxun YuCzech J. Genet. Plant Breed., 2023, 59(4):189-195 | DOI: 10.17221/108/2022-CJGPB Cytochrome P450 proteins belong to one of the largest families of enzyme proteins in plants and play important roles in plant growth and development and the stress response. In our previous studies, a cytochrome P450 gene, GhCYP94C1 (cytochrome P450 94C1), was functionally characterized as a positive regulator of seed germination, main root elongation and early flowering. However, whether the gene has other potential functions remains to be further explored. In our study, expression analysis showed that GhCYP94C1 was highly expressed in roots and was suppressed by drought treatment. Endogenous silencing of GhCYP94C1 via virus-induced gene silencing (VIGS) increased drought resistance in cotton plants, which was accompanied by the upregulated expression of the abscisic acid (ABA) biosynthesis gene nine-cis-epoxycarotenoid dioxygenase 9 (GhNCED9) during drought stress. Our findings suggested that GhCYP94C1 may play an important role in drought resistance. Combined with previous research results, the present results provide a theoretical basis for future breeding of new cotton varieties with early maturation and drought resistance. |
Therapeutic potential of natural products and antibiotics against bovine mastitis pathogen of cows and buffaloesOriginal PaperW Khan, SA Khan, FA Khan, S Khan, I Ullah, A Shah, I Uddin, S Khan, H Khan, MN Uddin, F Akbar, N QayumVet Med - Czech, 2023, 68(7):271-280 | DOI: 10.17221/80/2022-VETMED The present study aims to evaluate the prevalence and antimicrobial sensitivity of Staphylococcus aureus associated with bovine mastitis to selected antibiotics and plant extracts. In the current study, 140 milk samples were collected from cows and buffaloes. Among the 140 samples, 93 samples were positive for sub-clinical mastitis based on the California Mastitis Test (CMT). Out of the total positive samples, 45 were confirmed for S. aureus on a Mannitol salt agar media. The antimicrobial susceptibility test revealed that 44.82% of the isolates were resistant to cefoxitin (oxacillin) confirming methicillin-resistant S. aureus (MRSA) with a higher percentage (51.61%) in the buffalo than in the cow samples. Furthermore, the PCR assay confirmed the presence of the mecA gene in all the MRSA isolates. Among the seven tested antibiotics, sulfamethoxazole + trimethoprim showed high efficacy (71.1%) against methicillin-susceptible S. aureus isolates (MSSA). Oxytetracycline and sulfamethoxazole + trimethoprim showed 20% efficacy against MRSA followed by enrofloxacin (10%). On the other hand, the tested samples from Pistacia chinensis revealed that the ethyl acetate extract of bark showed a maximum zone of inhibition of 21.3 mm against MSSA and MRSA isolates at 3 000 µg/disc. Moreover, the methanol extract of Cotoneaster microphyllus formed a 12.3 mm and 9.1 mm zone of inhibition against the MSSA and MRSA isolates, respectively. |

Sap flow modelling based on global radiation and canopy parameters derived from a digital surface modelOriginal PaperTomá¹ Mikita, Zdenìk Patoèka, Elizaveta AvoianiJ. For. Sci., 2023, 69(8):348-359 | DOI: 10.17221/191/2022-JFS Sap flow represents water transport from roots to leaves through the xylem and is used to describe tree transpiration. This paper proposed and tested a procedure to estimate sap flow by calculating global radiation in a digital model of the tree canopy surface obtained by unmanned aerial vehicle imaging. The sap flow of nine trees was continuously measured in the field. In the digital surface model, individual canopies were automatically delineated, their parameters were determined and the global radiation incident on their surface on specific days was calculated. A polynomial relationship was found between sap flow and the calculated incident solar radiation during the morning hours with a coefficient of determination of 0.98, as well as a linear relationship between the decrease in radiation and sap flow during the afternoon with a correlation coefficient of 0.99. Using the Random Forest machine learning method, a model predicting the sap flow of the trees was created based on the global radiation and canopy parameters determined from the digital surface model of tree canopies. The resulting model was deployed on additional days and compared to field measurements of sap flow, achieving a correlation coefficient of 0.918. In addition, two linear regression models were created for a tree group, achieving coefficients of determination of 0.66 and 0.90. |

Strategies and methods for predicting soil organic matter at the field scale based on the provincial near infrared spectral databaseOriginal PaperShengyao Jia, Chunbo Hong, Hongyang Li, Yuchan Li, Siyuan HuSoil & Water Res., 2023, 18(3):158-168 | DOI: 10.17221/133/2022-SWR The development and provision of soil spectral library (SSL) could facilitate the application of near infrared (NIR) spectroscopy for economical, accurate, and efficient determination of soil organic matter (SOM). In this work, the performances of partial least squares regression (PLSR) and convolutional neural network (CNN) combined with the datasets of Zhejiang provincial SSL (ZSSL) and the feature subset (FS) were compared for the prediction of SOM at the target field. The FS dataset was chosen from ZSSL based on similarity to the spectral characteristics of the target samples. The results showed that compared with modelling using ZSSL, modelling using FS can greatly improve the prediction accuracy of the PLSR model, but the impact on the performance of the CNN model was limited. The method of mean squared Euclidean distance (MSD) was an effective way for determining the optimal spiking sample size for the PLSR model only using the spectral data of the spiking subset and the prediction set. The PLSR model combined with the FS dataset and the spiking subset determined by MSD achieved the optimal prediction results among all developed models, which is an accurate and easy-to-implement solution for the SOM determination based on ZSSL. |
Successful treatment of a benign, non-infected cyst in a dog by bone marrow injectionsCase ReportB Degorska, J Sterna, J Bonecka, M Sobczak-Filipiak, J JacewiczVet Med - Czech, 2023, 68(8):337-342 | DOI: 10.17221/19/2023-VETMED Bone cysts are rare orthopaedic problems in dogs. There are no clear treatment guidelines. A young male Shih Tzu was referred to Small Animal Clinic with fifth-degree lameness (5/5) of the left thoracic limb, and with swelling and deformation of the distal humeral region. The radiological assessment revealed an enlargement of the distal brachium and an extensive hypodense osteolytic lesion in the distal metaphyseal region of the humerus. Diagnosis of the bone cyst was formulated and treated with a mini-invasive method using autologous non-concentrated bone marrow injections. The treatment was successful, and at the three weeks, the cyst significantly changed its structure. The follow-up at 12 weeks after the first injection, and at one year revealed complete recovery. To our knowledge, this is the first evidence of a bone cyst in a young dog successfully treated with a minimally-invasive method by using a non-concentrated autologous bone marrow injection. |
