Clonning of DREB1 gene in wheat wild relatives and development of a DNA marker for its monitoring in wheat background

The DREB gene encodes the transcription factor DREB involved in the response of the plant to drought, salinity and heat. The DREB transcription factors induce the expression of multiple genes linked by signal transmission, abscisic acid-dependent and independent, in response to abiotic stress. Many wild species have evolved under extreme environmental conditions (drought, salinity), so they can serve as sources of new genetic variants of DREB in breeding wheat for stress resistance. The study of DREB orthologousgenes in wild relatives of wheat will permit to expand the set of genes in its breeding improvement using wide hybridization, and the design and application of molecular markers will facilitate transfer of these genes into a genome of bread wheat. Among the diversity of genes encoding DREB proteins, DREB1 is of the greatest interest due to itsinvolvement in control of plant resistance to various abiotic factors, such as drought, salinity, low temperatures. We were the first to study the DREB1 orthologs in members of the genera Thinopyrum, Dasypyrum and Pseudoroegneria...
