HISTONE MODIFICATIONS IN RESPONSE TO ABIOTIC STRESS

Journal Title: IJAR-Indian Journal of Applied Research - Year 2019, Vol 9, Issue 2

Abstract

Plants, being sessile, are subjected to multitudinous untoward environmental conditions perpetuated by a complex concourse of abiotic factors that possess the ability to negatively impact their growth, development or productivity. Stress conditions induce a plethora of plant responses, ranging from changes in growth rates and growth yields to altered gene expression and cellular metabolism. Under adverse conditions, plants perceive stimuli from the surrounding environment and in due course of time have developed extensive regulatory mechanisms that generate variations in gene, in response. Histone modications such as H3K9ac, H4ac, H3K4me3, H3K9me2, H3K27me3, H3K23ac, H3K27ac, along with DNA methylation have been found to be associated with altered gene expression in response to abiotic stresses which includes drought, extreme temperatures, and high salinity conditions. This review provides a comprehensive overview of histone modications that occur as part of chromatin changes, in response to drought, salinity, heat, cold and nutrient stress.
