All flowering plants adjust their reproductive period for successful reproduction. Flower initiation is controlled by a myriad of intensively studied factors, so it can occur in the most favorable conditions. However, the end of flowering is also a controlled process, required to optimize the size of the offspring and to maximize resource allocation. Reproductive arrest was described and mainly studied in the last century by physiological approaches, but it is much less understood at the genetic or molecular level. In this review, we present an overview of recent progress in this topic, fueled by highly complementary studies that are beginning to provide an integrated view of how the end of flowering is regulated. In this emerging picture, we also highlight key missing aspects that will guide future research and may provide new biotechnological avenues to improve crop yield in annual plants.
所有开花植物都会调整其繁殖期以实现成功繁殖。花的起始受众多经过深入研究的因素控制，因此可以在最有利的条件下发生。然而，开花的结束也是一个受控的过程，需要优化后代的大小并最大限度地分配资源。在上个世纪，生理方法描述并主要研究了生殖中止，但在遗传或分子水平上，人们对其了解要少得多。在这篇综述中，我们介绍了这一主题的最新进展，这些进展得益于高度互补的研究，这些研究开始提供一个综合的视角，了解开花的结束是如何被调控的。在这个新兴的图景中，我们还强调了关键的缺失方面，这些方面将指导未来的研究，并可能为提高一年生植物的作物产量提供新的生物技术途径。
