Abscisic Acid Mediated Abiotic Stress Tolerance in Plants

Abiotic stress is one of the major environmental stresses that decrease crop growth and yield even in irrigated soils worldwide. An important plant hormone abscisic acid (ABA) plays a vital role addressing various stresses, such as thermal or heat stress, high salinity level, heavy metal low temperature, drought, on radiation. Its well explained different processes for development, including germination seed, stomata closure, dormancy. Abscisic works through alteration gene expression levels subsequently analyzing cis trans-regulatory components receptive promoters. It considered to have an interaction with signaling elements taking part response seed development. In general, can be vulnerable tolerant when correlated actions stress-reacting genes are considered. Many transcription factors required regulation acid-responsive interacting their specific cis-acting components. Therefore, mechanism behind it should understood make plants stress-tolerant. This review explains significance function ABA concerning management biosynthesis, (TFs) associated tolerance.
