脱落是一个受到严格调控的发育过程，是对内源性和环境因素的反应。在农业方面，脱落调控对作物产量和质量有重大影响。作物驯化通常选择防止果实脱落，使其更容易收获。因此，更好地了解脱落的机制将为改进作物育种和收获方法的努力提供信息。在这篇文章中，我们总结了目前关于脱落的各种调节机制的知识。我们首先回顾了脱落带细胞在获得对脱落信号的响应能力时的调控。在此基础上，综述了植物脱落发生的调控机制，探讨了植物激素信号、发育因子和环境因素对脱落发生的调控作用。
Abscission is a tightly regulated developmental process that initiates in response to endogenous and environmental cues. In an agricultural context, regulation of abscission has substantial effects on crop productivity and quality. Crop domestication often selected against abscission of the fruit, allowing easier harvesting. A better understanding of the mechanisms underlying abscission will, therefore, inform efforts to improve crop breeding and harvesting practices. In this article, we summarize our current knowledge of the various regulatory mechanisms involved in abscission. We first review the regulation of abscission zone cells as they acquire competence in response to abscission signals. We then summarize the regulation of abscission initiation, exploring the phytohormone signals, developmental factors, and environmental cues regulating the initiation of abscission.
