| 摘 要： | 土壤盐渍化是迫使经济作物减产甚至严重限制农业生产的主要原因。作为主要的非生物胁迫因素，高盐可引起植物体内离子紊乱，最终导致植物产量降低，死亡率升高。ABA作为植物五大激素之一，是公认的抗性激素，在响应植物盐胁迫时起到积极作用。笔者就近年来ABA在响应植物盐胁迫时的相关性、作用机制及其信号转导途径进行综述，并对今后相关领域的研究予以展望。分析表明：ABA可响应植物盐胁迫，并在植物耐盐信号转导中发挥极为重要的作用，同时形成一系列适应性分子机制，使得植物通过自身响应机制抵抗高盐胁迫。

| 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. |
