摘　要：摘　要：ASR (abscisic acid， stress， ripening) 蛋白是植物特有的一类蛋白质家族。ASR 基因在成熟果实中表达，也受脱落酸和胁迫诱导在营养组织中表达。现对ASR 基因家族的发现和进化、时空表达和ASR 蛋白的特性及亚细胞定位等进行综述，特别对ASR 蛋白抗非生物胁迫功能及其可能的分子机制进行了总结，旨在为ASR 蛋白的农业应用提供新思路。

Abstract: Abstract: Abscisic acid stress ripening (ASR) protein is only found in plant kingdom up to now. ASR gene was expressed not only in ripening fruit， but also induced by ABA and stresses in vegetable tissues. This review summarizes the cloning， characterization， evolution and expression pattern of ASR gene， the amino acid composition and subcellular localization of ASR protein. Especially， the role and molecular mechanism of ASR protein in abiotic-stresses resistance are analyzed to provide new insight for applying ASR protein in agriculture.
