Self-incompatibility (SI) in angiosperms prevents inbreeding and promotes outcrossing to generate genetic diversity. In many angiosperms, self/non-self recognition in SI is accomplished by male-specificity and female-specificity determinants (S-determinants), encoded at the S-locus. Recent studies using genetic, molecular biological and biochemical approaches have revealed that angiosperms utilize diverse self/non-self discrimination systems, which can be classified into two fundamentally different systems, self-recognition and non-self recognition systems. The self-recognition system, adopted by Brassicaceae and Papaveraceae, depends on a specific interaction between male and female S-determinants derived from the same S-haplotype. The non-self recognition system, found in Solanaceae, depends on non-self (different S-haplotype)-specific interaction between male and female S-determinants, and the male S-determinant genes are duplicated to recognize diverse non-self female S-determinants.
植物中的自交不亲和性（Self-incompatibility，SI）可以防止近亲繁殖，促进异交以产生遗传多样性。在许多植物中，SI 中的自/非自我识别是通过雄性特异性和雌性特异性决定因素（S-决定因素）来完成的，这些决定因素编码在 S 基因座上。最近的研究使用遗传、分子生物学和生物化学方法揭示了植物利用多种自/非自我歧视系统，这些系统可以分为两种基本不同的系统，即自我识别系统和非自我识别系统。拟南芥和罂粟科采用的自我识别系统依赖于来自相同 S 单倍型的雄性和雌性 S 决定因素之间的特定相互作用。在茄科中发现的非自我识别系统依赖于雄性和雌性 S 决定因素之间的非自我（不同 S 单倍型）特异性相互作用，并且雄性 S 决定基因被复制以识别多种非自我雌性 S 决定因素。
