Transcriptional Regulatory Networks in Response to Abiotic Stresses in Arabidopsis and Grasses

Abstract

Various abiotic stresses such as drought, high salinity, high temperature, and low temperature negatively impact plant growth and productivity of crops. Plants have adapted to respond to these stresses at the molecular, cellular, physiological, and biochemical level, enabling them to survive. Various adverse environmental stresses induce the expression of a variety of genes in many plant species Numerous stress-induced genes have been identified using microarray experiments The products of these genes are thought to promote stress tolerance and to regulate gene expression through signal transduction pathways
