植物自交不亲和系统的频率依赖选择是固有的，并且在理论上已经很好地理解了。一个自交不亲和位点导致了基因组中一个强大的多样性峰值，导致了物种间多样性的独特分布，并可能增加了近亲物种之间的渐渗。我们回顾了最近的实证研究，证明了这些特征，并将实证结果与理论预测联系起来。我们展示了这些特征是如何被利用在多等位基因平衡选择下寻找其他基因和推断最近的自交不亲和的崩溃。
Frequency-dependent selection at plant self-incompatibility systems is inherent and well understood theoretically. A self-incompatibility locus leads to a strong peak of diversity in the genome, to a unique distribution of diversity across the species and possibly to increased introgression between closely related species. We review recent empirical studies demonstrating these features and relate the empirical findings to theoretical predictions. We show how these features are being exploited in searches for other genes under multi-allelic balancing selection and for inference on recent breakdown of self-incompatibility.
