Fertilization in flowering plants begins with a pollen grain bearing the male gametes landing on the female stigma. Several mechanisms enable the stigma to discriminate between the different types of pollen that it may receive, of which the best studied is self-incompatibility. The molecules that regulate self-incompatibility are well characterized in two plant families, the Solanaceae and Brassicaceae. This list has recently been extended to include candidates for self-incompatibility molecules from the Rosaceae, Papaveraceae and Poaceae. The information provided by the sequences of these molecules gives insight into the mechanisms and evolution of self-incompatibility in the different families of flowering plants.
开花植物的受精始于携带雄配子的花粉粒落在雌蕊柱头上。有几种机制使柱头能够区分它可能接收的不同类型的花粉，其中研究得最透彻的是自交不亲和性。在茄科和十字花科这两个植物科中，调节自交不亲和性的分子已得到充分表征。最近，这个名单已经扩大到包括蔷薇科、罂粟科和禾本科中自交不亲和性分子的候选物。这些分子序列提供的信息有助于深入了解不同开花植物科中自交不亲和性的机制和进化。
