| Popis: | Drought and salinity are major constraints to agriculture. In this review, we presentan overview of the global situation and the consequences of drought and salt stress connected toclimatic changes. We provide a list of possible genetic resources as sources of resistance or toleranttraits, together with the previous studies that focused on transferring genes from the germplasm tocultivated varieties. We explained the morphological and physiological aspects connected to hydricstresses, described the mechanisms that induce tolerance, and discussed the results of the mainstudies. Finally, we described more than 100 genes associated with tolerance to hydric stresses inthe Triticeae. These were divided in agreement with their main function into osmotic adjustmentand ionic and redox homeostasis. The understanding of a given gene function and expressionpattern according to hydric stress is particularly important for the efficient selection of new tolerantgenotypes in classical breeding. For this reason, the current review provides a crucial reference forfuture studies on the mechanism involved in hydric stress tolerance and the use of these genes in mark assistance selection (MAS) to select the wheat germplasm to face the climatic changes. |
