摘要
盐胁迫是常见的非生物胁迫因素之一并严重地影响着植物的生长发育。简述了植物在应对盐胁迫时,在胁迫信号的感知、信号的转导和传递、胁迫诱导基因的表达等方面所形成的一系列适应性的分子机制,回顾了近年来对脱落酸信号转导和其受体的研究。分析表明脱落酸受体PYR/PYL/RCAR(pyrabatin resistance/like-pyrabatin resistance/regularly component of ABA receptors)的发现使得ABA的信号转导通路更为清楚,使ABA与植物耐盐胁迫的关系更加明确,认为ABA在植物耐盐信号转导途径中发挥了重要的作用,与经济作物的耐盐性密切相关。
High salinity is the most common abiotic stress factor in environment which impacts on the plant growth. This paper reviewed a series of molecular mechanisms of plant response to salt stress. The mechanism included signal perception, signal transduction, transmission and stress-induced gene expression and the studies on ABA signal transduction and ABA receptors in recent years. The analysis showed that the discovery of the ABA PYR/PYL/RCAR （pyrabatin resistance/ like-pyrabatin resistance/regularly component of ABA receptors） made the ABA signal transduction pathway more clearly, the relationship between ABA and salt stress was defined. ABA had play an important role in salt tolerance of plant signal transduction pathways, and closely related to the salt tolerance of economic crops.
