摘要
芸薹属植物自交不亲和性受单一位点的复等位基因控制 ,此位点命名为S位点。它决定柱头表面花粉识别的专一性。S位点糖蛋白基因 (SLG)和S受体激酶基因 (SRK)是控制芸薹属植物花柱自交不亲和性的两个关键因子。本文介绍了编码自交不亲和性的S位点的SLG、SRK和花粉S基因的鉴定、结构及功能 ,并对其信号传导途径的可能机制做了简要概述。
Self_incompatibility in Brassica is controlled by a single multiallelic locus (designated as S locus) that is responsible for pollen recognition on the stigma surface. SLG and SRK are thought to be the key molecules of self_incompatibility in Brassica . This article reviewes the identification, structure and function of S locus genes (including SLG, SRK and pollen S gene), and some aspects on signal transduction pathway involved in self_incompatible reaction.
