Flowers have fascinated humans for millennia, not only because of their beauty, but also because they give rise to fruits, from which most agricultural products are derived. In most angiosperms, the number and position of floral organs are morphologically and genetically defined, and their development is tightly controlled by complex regulatory networks to ensure reproductive success. How flower development is temporally initiated and spatially maintained has been widely researched. As the flower develops, the balance between proliferation and differentiation dynamically shifts towards organogenesis and termination of floral stem cell maintenance. In this review, we focus on recent findings that further reveal the intricate molecular mechanisms for precise timing of floral meristem termination.
花已经吸引人类数千年了，不仅因为它们的美丽，还因为它们产生了果实，而大多数农产品都来自于果实。在大多数被子植物中，花器官的数量和位置在形态和遗传上是确定的，它们的发育受到复杂的调控网络的严格控制，以确保繁殖成功。花发育是如何在时间上启动和空间上维持的，这个问题已经得到了广泛的研究。随着花的发育，增殖和分化之间的平衡动态地向器官发生和终止花分生组织维持的方向转变。在这篇综述中，我们重点介绍了最近的发现，这些发现进一步揭示了精确控制花分生组织终止的复杂分子机制。
