中文摘要：

富含半胱氨酸蛋白（cystein-rich proteins,CRPs）是动植物中广泛存在的一类小的分泌性蛋白,具有广泛的生物学功能,如防御、蛋白酶抑制、重金属解毒等。人们在深入研究植物CRPs防御功能的同时,发现CRPs还参与调节植物的生长、发育、生殖等。本文综述了植物CRPs的分类、结构及其在植物生长发育、生殖信号转导等方面的研究进展。

英文摘要：

Cysteine-rich proteins are a kind of small secretory proteins widely existing in anminals an plants,have extensive biological functions,such as defense,proteinase inhibitors,heavy metal detoxification,etc.Research has showen CRPs regulate growth,development and reproduction of plants besides the function of defense.The progress of CRPs in classification,structure,plants growing development and reproduction signal transduction were reviewed.
