显花植物交配模式和性系统的显著多样性吸引了进化生物学家超过世纪。关于这一主题的持久问题包括为什么性多态性在100多个植物家族中独立进化，以及为什么自花受精和异花受精的比例在种群内和种群之间经常发生显着变化。关于植物交配系统进化动力学的重要新见解建立在理论模型以及创新的田间和实验室实验的坚实基础之上。然而，随着这一领域的进步步伐加快，研究人员越来越难以跟踪其主要研究领域之外的发展，在这篇观点论文中，我们强调了三个跨越和整合不同学科的重要主题：形态学，物候学和生理学的变化，伴随着向自交的过渡;开花植物花粉池多样性的进化结果;性多态性的进化动力学。我们还强调了分子技术的最新发展，这将有助于更有效和更具成本效益的研究交配模式在大型自然种群，花粉运输的动态研究，和调查的遗传基础上的性多态性。这一观点也作为介绍植物交配系统的进化特刊。这份特刊中的15篇论文提供了最近发现的鼓舞人心的例子，以及即将到来的令人兴奋的发展。
The remarkable diversity of mating patterns and sexual systems in flowering plants has fascinated evolutionary biologists for more than a century. Enduring questions about this topic include why sexual polymorphisms have evolved independently in over 100 plant families, and why proportions of self- and cross-fertilization often vary dramatically within and among populations. Important new insights concerning the evolutionary dynamics of plant mating systems have built upon a strong foundation of theoretical models and innovative field and laboratory experiments. However, as the pace of advancement in this field has accelerated, it has become increasingly difficult for researchers to follow developments outside their primary area of research expertise.In this Viewpoint paper we highlight three important themes that span and integrate different subdisciplines: the changes in morphology, phenology, and physiology that accompany the transition to selfing; the evolutionary consequences of pollen pool diversity in flowering plants; and the evolutionary dynamics of sexual polymorphisms. We also highlight recent developments in molecular techniques that will facilitate more efficient and cost-effective study of mating patterns in large natural populations, research on the dynamics of pollen transport, and investigations on the genetic basis of sexual polymorphisms. This Viewpoint also serves as the introduction to a Special Issue on the Evolution of Plant Mating Systems. The 15 papers in this special issue provide inspiring examples of recent discoveries, and glimpses of exciting developments yet to come.
