This review focuses on the evolution of plant hormone signaling pathways. Like the chemical nature of the hormones themselves, the signaling pathways are diverse. Therefore, we focus on a group of hormones whose primary perception mechanism involves an Skp1/Cullin/F-box-type ubiquitin ligase: auxin, jasmonic acid, gibberellic acid, and strigolactone. We begin with a comparison of the core signaling pathways of these four hormones, which have been established through studies conducted in model organisms in the Angiosperms. With the advent of next-generation sequencing and advanced tools for genetic manipulation, the door to understanding the origins of hormone signaling mechanisms in plants beyond these few model systems has opened. For example, in-depth phylogenetic analyses of hormone signaling components are now being complemented by genetic studies in early diverging land plants. Here we discuss recent investigations of how basal land plants make and sense hormones. Finally, we propose connections between the emergence of hormone signaling complexity and major developmental transitions in plant evolution. Expected final online publication date for the Annual Review of Plant Biology, Volume 71 is April 29, 2020. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

植物激素反应途径的演变

本综述重点关注植物激素信号通路的演变。就像激素本身的化学性质一样，信号通路也是多种多样的。因此，我们关注一组主要感知机制涉及 Skp1/Cullin/F-box 型泛素连接酶的激素：生长素、茉莉酸、赤霉酸和独脚金内酯。我们首先比较这四种激素的核心信号通路，这些通路是通过在被子植物模型生物中进行的研究建立的。随着新一代测序技术和先进的基因操作工具的出现，了解除了这些少数模型系统之外的植物激素信号机制起源的大门已经打开。例如，对激素信号成分的深入系统发育分析现在得到了早期分化陆地植物的遗传研究的补充。在这里，我们讨论了最近对基生陆生植物如何制造和感知激素的研究。最后，我们提出了激素信号复杂性的出现与植物进化中的主要发育转变之间的联系。《植物生物学年度评论》第 71 卷的预计最终在线出版日期为 2020 年 4 月 29 日。请参阅 http://www.annualreviews.org/page/journal/pubdates 了解修订后的估计值。
