Self-incompatibility (SI), a genetically controlled mechanism to prevent inbreeding in plants, offers a relatively simple model system for studying the interactions between plant cells or between a plant cell and the secreted product or products of another cell. Examples of two major types of SI, gametophytic and sporophytic, have been studied by cloning cDNAs corresponding to glycoproteins of the female tissues that segregate with particular variants encoded by the putative S locus. These secreted glycoproteins are envisaged to interact with the currently undescribed pollen component to cause arrest of pollen tube growth.
自交不亲和性（SI）是一种防止植物近亲繁殖的遗传控制机制，为研究植物细胞之间或植物细胞与另一个细胞分泌产物之间的相互作用提供了一个相对简单的模型系统。通过克隆与雌性组织糖蛋白相对应的cDNA，研究了两种主要类型的SI（配子体自交不亲和性和孢子体自交不亲和性）的例子，这些糖蛋白与假定的S位点编码的特定变体分离。这些分泌的糖蛋白被设想与目前尚未描述的花粉成分相互作用，从而导致花粉管生长停滞。
