Identification of osmotic stress-responsive genes from Leymus mollis, a wild relative of wheat (Triticum aestivum L.).

ABSTRACT: The tolerance of the dune grass Leymus mollis (Triticeae; Poaceae) to various biotic and abiotic stresses makes it a very useful genetic resource for wheat breeding. Wide hybridization between L. mollis and wheat allows the introduction of Leymus chromosomes into the wheat genetic background and facilitates the integration of useful traits into wheat. However, the genetic basis controlling the physiological tolerance of L. mollis to multiple environmental stresses remains largely unexplored. Using suppression subtractive hybridization, we identified 112 osmotic-stress-responsive genes from L. mollis and confirmed their differential expression under osmotic stress. These genes were categorized into 13 functional categories, including cell defense and stress response, transcriptional regulat
