China Title: Extracellular ATP: a potential molecule regulating the defence response of plants to biotic stresses - a review Abstract: Although adenosine 5'-triphosphate (ATP) is commonly considered as an intracellular energy currency molecule, animal, plant, and microbial cells can secrete ATP from the cytosol into the extracellular matrix. In plant cells, extracellular ATP (eATP) is found to play important roles in regulating several physiological processes, such as cell growth, development, and death. Interestingly, recent studies suggest that eATP could be a potential molecule required for the regulation of the defence responses of plants to pathogen infection and herbivore attack. This review article summarises the preliminary studies that have been conducted regarding the possible involvement of eATP in plant defence responses to biotic stress. And, we also attempt to address some speculations and theoretical discussions to aid future research in this area.

The use of secondary metabolites in a defensive manner isolated from plants is a tradition more than 3000 years old. However, despite current intensive research, the assortment of suitable commercial products is very limited and insufficient in view of the global rise in the demand for biopesticides. Farm products as well as new basic substances offer an important perspective of being widely used in the protection against harmful insects due to their multiple undoubted benefits. These benefits, which are also drawbacks of botanical insecticides, as well as their history in addition to their presence and perspective are critically reviewed in this paper.

China Title: Postulation of seedling stem rust resistance genes of Yunnan wheat cultivars in China Abstract: To determine stem rust resistance genes of wheat varieties in Yunnan province, 11 Chinese strains of Puccinia graminis f.sp. tritici with different virulence and 1 artificial mutant strain were used in 110 wheat varieties. The results indicated that among the 45 Sr genes, Sr31, Sr5, SrTmp, Sr30, Sr36, Sr8a, Sr11, Sr24, Sr29, Sr34, Sr9e, Sr26, Sr38, Sr47, and SrTt3 were characterised in 55 wheat varieties singly or in combination. Sr5, Sr31, SrTmp, Sr36, and Sr30 were contained in 17, 16, 5, 5, and 3 cultivars, respectively. Six cultivars contained Sr24 and/or Sr34. Three plant materials likely contained one or more of Sr8a, Sr11, Sr34, and Sr23 genes as well as other unknown genes. The 16 immune or highly resistant varieties contained one or more of Sr9e, Sr26, Sr38, Sr47, SrTt3, and other unknown resistance genes. The reaction types on 22 of the tested cultivars were different from those on Sr genes tested, and their resistance genes could not be analysed. Additionally, 17 varieties were susceptible to all the tested strains, having no postulation value. Our study provides a basis for improved breeding of stem rust resistant wheat in China.

A disease was observed on 20% of the trees. The first symptoms are wilting, stunting, chlorosis, and discolouration of needles, which turned yellow on affected twigs, then red and finally they fell off. Isolations of the pathogen were done from the discoloured tissues of needles (twenty samples from each tree) on Potato Dextrose Agar. Colonies of the fungus (3-4 Petri dishes from each tree) were initially aerial, white or slightly violet, but with age they became red and red pigments were produced in agar. The observed micromorphological characteristics of the fungus, such as presence of simple and proliferating conidiophores with polyphialides, microconidia, macroconidial shape, and chlamydospore presence matched the description of Fusarium sporotrichioides. The identity of the fungus was confirmed by phylogenetic analysis of internal transcribed spacer (ITS) sequences. Sequence comparisons placed the fungus to the species F. sporotrichioides with similarity of 99.6% at the ITS sequence level.

We predicted that maximum abundances on late maturing cultivars would be greater than on early ones. This was tested using 8 spring wheat cultivars that differed in the length of time to senescence. In a 4-year experiment, numbers of aphids were checked at weekly intervals. Maximum abundances on late-maturing cultivars were significantly greater than those on early cultivars. However, the length of the vegetation period affected maximum abundances less than did the annual variation in aphid abundance. Genetic disposition for early ripening thus tends to decrease aphid numbers, but manipulation of this character is unlikely to become an important source of aphid resistance.

Healthy potato plants at different growth stages (4, 5, and 7 weeks after germination) were exposed separately to four different B. cockerelli densities (0, 5, 20, and 40 psyllids per cage) in field cages and Zebra chip (ZC) symptoms, leaf photosynthetic rates, tuber yield, and total nonstructural carbohydrate accumulation in leaves and tubers of healthy and B. cockerelli-infested plants were monitored. Potato psyllid nymph and egg populations reached a seasonal peak at 6 weeks after the exposure to insect. Younger plants at 4-week growth stage after germination were more susceptible to B. cockerelli infestation and ZC expression than older plants. As few as five B. cockerelli adults were enough to transmit the ZC pathogen and cause ZC expression both in foliage and tuber. At the density of 20 psyllids per cage, more than 50% of plants showed ZC symptoms in tubers. Furthermore, B. cockerelli infestation reduced leaf photosynthesis rates (Pn), resulting in less starch and more reducing sugars in tubers, and hence reduced tuber weight and yield, especially when psyllid infestation occurred at the early growth stages. The results indicate that early B. cockerelli infestation of younger plants was associated with more severe ZC expression in both foliage and tubers, leading to earlier dead plants. The data suggest that strategies for controlling B. cockerelli during early potato crop development could thus lessen the severity of ZC development.

Landsat images from the period before (2002) and after the T. viridana infestation (2007, 2014) were compared in oak forests of Zagros in western Iran. The Normalised Difference Vegetation Index (NDVI) was calculated for the test area from Landsat 5, 7, and 8 images. Because the red and near-infrared spectral bands of Landsat 8 OLI sensors are different from the other two, a model for the calibration of Landsat OLI NDVI was developed. The proposed model with a correlation coefficient of 0.928 and root mean square error of 0.05 turned out to be applicable and the NDVI decreased significantly during the observation period. Taking into account the protection status of the area and small fluctuations in temperature, the decrease in NDVI could be attributed to T. viridana damage.

To our knowledge, the occurrence of D. micans on P. orientalis in Central Europe has not been described yet. We found that D. micans preferred P. orientalis over P. pungens and other coniferous trees in urban areas. In laboratory conditions, 352 adults of D. micans emerged and only 1 predator, Rhizophagus grandis (Gyllenhal) (Coleoptera: Monotomidae), was recorded. D. micans has a potential to become a serious pest of P. orientalis and P. pungens in urban, and in air-polluted areas.
