Plants maintain their yield, vigour and genetic diversity through appropriate selection of genetically diverse mates while rejecting related partners. Given the fact that crop-yield is the most important agronomic trait, understanding the molecular mechanism behind plant reproduction is a major research priority. Successful plant reproduction is dependent on a compatible interaction between the pollen/pollen tube and the pistil. In plant species of Brassicaceae, which are characterized by dry stigmas, only compatible pollen can induce the pistil to provide all the necessary resources for its hydration and penetration into the stigmatic tissue. In contrast, during

植物通过适当选择遗传多样性的配偶，同时拒绝相关的伴侣，保持其产量，活力和遗传多样性。鉴于作物产量是最重要的农艺性状，了解植物繁殖背后的分子机制是一个主要的研究重点。成功的植物繁殖依赖于花粉/花粉管和雌蕊之间的相容性相互作用。在以干燥柱头为特征的菊科植物中，只有相容的花粉才能诱导雌蕊为其水化和渗透到柱头组织中提供所有必要的资源。相反，在
