Developmental and environmental signals converge on cell cycle machinery to achieve proper and flexible organogenesis under changing environments. Studies on the plant cell cycle began 30 years ago, and accumulated research has revealed many links between internal and external factors and the cell cycle. In this review, we focus on how phytohormones and environmental signals regulate the cell cycle to enable plants to cope with a fluctuating environment. After introducing key cell cycle regulators, we first discuss how phytohormones and their synergy are important for regulating cell cycle progression and how environmental factors positively and negatively affect cell division. We then focus on the well-studied example of stress-induced G2 arrest and view the current model from an evolutionary perspective. Finally, we discuss the mechanisms controlling the transition from the mitotic cycle to the endocycle, which greatly contributes to cell enlargement and resultant organ growth in plants. Expected final online publication date for the Annual Review of Plant Biology, Volume 72 is May 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

响应激素和环境对植物细胞周期的调节。

发育和环境信号在细胞周期机器上汇聚，以在不断变化的环境中实现适当而灵活的器官发生。关于植物细胞周期的研究始于30年前，积累的研究揭示了内部和外部因素与细胞周期之间的许多联系。在这篇综述中，我们着重于植物激素和环境信号如何调节细胞周期，从而使植物能够应对不断变化的环境。在介绍了关键的细胞周期调节剂之后，我们首先讨论植物激素及其协同作用对调节细胞周期进程的重要性，以及环境因素如何对细胞分裂产生积极和消极的影响。然后，我们集中研究应力引起的G2阻滞的经过充分研究的示例，并从进化的角度查看当前模型。最后，我们讨论了控制从有丝分裂周期向内周期过渡的机制，这极大地促进了植物的细胞增大和器官生长。《植物生物学年度评论》第72卷的最终最终在线发布日期为2021年5月。有关修订的估算，请参见http://www.annualreviews.org/page/journal/pubdates。
