Název v původním jazyce

Crop proteome ganges under abiotic stresses

Popis výsledku v původním jazyce

The ability of crops to survive abiotic stress such as cold or drought depends on their genotype (polygenic trait) and is affected by environment. Winter crops are able to survive long-term periods of cold during winter. However, within a winter crop gene pool, there are large differences in the ability to acquire frost tolerance (FT) during cold acclimation (CA). CA includes plant complex physiological response to cold aimed at minimizing the harmful effects of low temperatures and gaining a sufficient level of FT. After sufficient CA, the plants could survive freezing temperatures lethal for nonacclimated plants. The stress acclimation is important also for other abiotic stresses (e.g., drought, salt). The aim of this study was to reveal components of plant response to cold (wheat, barley, oilseed rape), drought (barley, oilseed rape, melon) and salt stress (barley) by proteomics analysis (protein immunoblot, 2DE-DIGE). The stress-induced processes result in changes in carbohydrate metabolism and photosynthesis, protein biosynthesis, folding and degradation as well as reactive oxygen species (ROS) scavenging and biosynthesis of compatible solutes and stress-related proteins among other processes. Moreover, the differences in stress responses were found between different crops, genotypes and also plant organs. Comprehension of mechanism by which crops cope with abiotic stress is essential for breeding new resistant cultivars and thus for increasing yields in lower productive areas.
