Abstract

Drought, low temperature and salinity are the most important abiotic stress factors limiting crop productivity.A genomic map of major loci and QTLs affecting stress tolerance in Triticeae identified the crucial role of thegroup 5 chromosomes, where the highest concentration of QTLs and major loci controlling plant’s adaptation tothe environment (heading date, frost and salt tolerance) has been found. In addition, a conserved region with amajor role in drought tolerance has been localized to the group 7 chromosomes. Extensive molecular biologicalstudies have led to the cloning of many stress-related genes and responsive elements. The expression of somestress-related genes was shown to be linked to stress-tolerant QTLs, suggesting that these genes may represent themolecular basis of stress tolerance. The development of suitable genetic tools will allow the role of stress-relatedsequences and their relationship with stress-tolerant loci to be established in the near future.
