Abstract: Soil salinization is the main reason of economic crop failure and severely limits agricultural production. As a primary abiotic stress factor, high salinity results in the disorder of ionic equilibrium, eventually leads to the reduction of crop yield and the increase of mortality rate. Abscisic acid (ABA), which is one of the five phytohormone groups, is generally acknowledged as a resistant hormone and plays a positive role in plant salt stress response. The author reviewed the correlation, mechanism and signal transduction pathway of ABA in plant salt stress response during recent years, and forecasted researches in the future. The analysis indicated that ABA could response to plant salt stress and also played an important role in plant salt tolerance signal transduction pathway. With the formation of a series of molecular adaptability mechanisms, plant could resist high salinity stress via self-response.
