Abstract

To cope with unpredictably environmental perturbations and sometimes stresses, plants have evolved with some mechanisms so that these developing stresses can be sensitivity perceived and the physiology can be rapidly regulated. Such perception and regulation can be a kind of feed-forward mechanism and may involve many biochemical and physiological processes and/or the expression of many genes. Although many dehydration-responsive genes have been identified, much fewer of their functions have been known. Such stress-induced responses should include the initial perception of the dehydration signal, then the complicated signal transduction and cellular transmission until to the final gene activation or expression. As an important plant stress hormone abscisic acid (ABA) mediates many such responses. We believe that starting from the initial perception of dehydration to the gene expression leading to the stress-induced ABA biosynthesis is the most important stress signal transduction pathway among all the plant responses to stresses. Identification of the genes involved and understanding their roles during stress perception and physiological regulation shall be the most important and interesting research field in the coming years.
