| 摘 要： | ASR蛋白（the abscisic acid，stress，ripening protein）是生物体中广泛存在的一类与渗透调节有关的家族蛋白，植物受到逆境胁迫（如干旱、低温、盐胁迫、ABA等）后，ASR蛋白大量表达，可以减轻逆境引起的伤害。ASR蛋白在细胞中可以稳定细胞膜结构，作为分子伴侣，具有结合离子和防止氧化等作用，被认为是在胁迫过程中对植物起保护作用的物质之一。针对这些重要特性，综述了ASR蛋白分类、结构和编码基因及其表达调控方式及ASR基因表达、ASR蛋白积累与植物抗逆性的关系等方面的研究进展。

| Abstract: | ASR（the abscisic acid，stress，ripening protein）proteins are a suite of important family proteins found in organisms，which are generally involved in osmoregulation. They will be induced in plants under stress conditions，such as drought，low temperature，salt stress and ABA. The overexpression of ASR proteins can reduce plant injure by stress. ASR proteins can stabilize the cell membrane structure，and as molecular chaperones，can combine ions and prevent oxidation. In current paper，the classification and structure of ASR proteins，encoding genes，the expression and regulation of ASR proteins，and the relationship among ASR gene expression，ASR protein accumulation and plant stress tolerance has been summarized. |
