Research Progress on the Tolerance of Abscisic Acid in Plants to Abiotic Stresses

The growth and development of plants are inhibited by abiotic stress, which is one of the factors limiting crop yield. Abscisic acid (ABA) is an important phytohormone and plays a key role in plant response to abiotic stresses. In this review, abscisic acid was introduced from its discovery, distribution and transportation. It was discussed the role of abscisic acid in abiotic stresses from three aspects, drought stress, salt stress and high temperature stress, and the application prospect of abscisic acid in agriculture was prospected.
