中文摘要：

芸薹属的自交不亲和性受S位点基因控制，其上的SRK基因和SCR／SP11基因是自交不亲和反应中的两个关键因子，另外所发现的其他因子也对自交不亲和发挥了重要作用。文章介绍了影响自交不亲和的功能因子及其分子结构特征和功能，对自交不亲和反应的分子机制作了进一步阐述，同时对这些功能基因在芸薹属植物甘蓝染色体组上的定位研究作出展望。

英文摘要：

The self-incompatibility （SI） of Brassica is controlled by S locus genes, and SRK gene and SCR/ SP11 gene are two key factors in SI reaction; in addition, other functional factors also play important roles in SL The article introduced the characteristics of molecular structure and function of S locus genes and functional factors affecting IS, and discussed the molecular mechanism of SI Reaction. At the same time, gene mapping on genome of these functional molecules for Brassica oleracea were prospected.
