中国人. 植物自交不亲和性是植物花粉―雌蕊相互识别,防止其近亲繁殖的重要机制,是植物发育生物学的研究热点之一。蔷薇科果树如梨、苹果、李子等表现出自交不亲和性,该反应由S位点（S-locus）的一对S等位基因,即雌蕊和花粉的S基因控制,分别为S-RNase和S-locus F-box/S-haplotype-specific F-box基因。本文综述了蔷薇科果树雌蕊和花粉S基因的鉴定及其结构和进化的特性、自交亲和性突变机制及自交不亲和性反应发生过程中花粉生理生化变化及其信号转导机制等,以期为深入系统研究蔷薇科果树自交不亲和及亲和性机制提供参考。

The plant self-incompatibility is an important mechanism to prevent inbreeding by pollen-pistil of mutual recognition, and it is one of the frontier topics of plant developmental biology. Rosaceae fruit trees such as apples, pears and plums exhibit self-incom- patibility. This reaction in this species is controlled by the pistil and pollen S gene, named the S-RNase and the S-locus F-box/S- haplotype-specific F-box genes, respectively. In this review, we summary of Rosaeeae fruit trees pistil and pollen S gene identification, structural and evolutionary characteristics, self-compatible mutation mechanism, and pollen physiological and biochemical characteristics and signal transduetion mechanisms during the self-incompatibility reaction. It will be used to provide reference for further research in this field.
