In Silico mapping of some genes responsible for abiotic stress tolerance in cereals.

Abstract

Abiotic stresses such as drought, high salinity, cold and low temperature cause great reduction in yields of major crops and affect plant growth. Modern agriculture faces abiotic stresses, especially salinity and drought as major factors limiting crop productivity worldwide. Response to abiotic stresses is a very complex phenomenon. Plants usually respond to the abiotic stresses at the molecular, physiological and biochemical levels, helping them to adapt with these stresses. MYB transcription factor is one of the major families of plant-specific TFs, has been related to drought and salinity responses. In this review the genes related to MYB TF family are selected and In Silico comparative mapping for these genes are performed. The identification and characterization of various genes involved in drought and salinity stress responses play an essential role in crop improvement, such as marker-assisted selection (MAS) and that very important for the breeders, helping them in their breeding programs as well as to develop stress tolerant crops.
