The Research Progress of Plant DNA Methylation Variation under Stresses
Stress refers to the organism under the stimulus of constant exposure to the environment.Plants have the ability to set up the system of protection and adaptation.Adversity stress inhibits the growth,development and reproduction of the organism.It often determines the distribution of the species.What is important is that it provides a selective dynamic evolution for a specific population.Plants can cope with stress through three different strategies,and these three different strategy is to endure,resistance and avoid or final escape.DNA methylation,as an epigenetic phenomenon,can make the gene function change without changing the DNA sequence via the effect of methylase,in response to external environmental stimuli.This change can often be passed on to offspring and form the epigenetic memory,this provides a possibility for cultivating plants resistant varieties.The research progress of plants DNA methylation modification under adversity stresses weve reviewed,aimed at further understanding the effects of DNA methylation changes to plant resistance.
