Self-incompatibility (SI) is a widespread mechanism in flowering plants that prevents self-fertilization. Self-pollen recognition relies on the products of genes located at the S (self-incompatibility) locus. Significant progress towards understanding molecular interactions allowing stigmatic cells to recognize and reject self-pollen in Brassica has been made during the past two years. Thus, the male and female determinants responsible of the self-incompatibility (SI) response have been identified. The structural features of these molecules strongly suggest that SI response is triggered by a ligand-receptor interaction.
自交不亲和性（SI）是开花植物中广泛存在的一种防止自花授粉的机制。自花花粉识别依赖于位于S（自交不亲和）位点的基因产物。在过去两年里，在理解允许芸苔属植物柱头细胞识别和排斥自花花粉的分子相互作用方面取得了重大进展。因此，已经确定了负责自交不亲和性（SI）反应的雄性和雌性决定因素。这些分子的结构特征强烈表明，SI反应是由配体-受体相互作用触发的。
