Hormonal cues regulate many aspects of plant growth and development, facilitating the plant's ability to systemically respond to environmental changes. Elucidating the molecular mechanisms governing these signaling pathways is crucial to understanding how plants function. Structural and functional biology methods have been essential in decoding plant genetic findings and revealing precise molecular actions at the protein level. Past studies of plant hormone signaling have uncovered mechanisms that involves highly coordinated protein turnover to elicit immediate cellular responses. Many phytohormone signaling pathways rely on the ubiquitin (Ub) proteasome system, specifically E3 Ub ligases, for perception and initiation of signaling transduction. In this review, we highlight structural aspects of plant hormone-sensing mechanisms by Ub ligases and discuss our current understanding of the emerging field of strigolactone signaling.

植物激素信号感知和调节泛素里加斯的结构方面。

激素提示调节植物生长和发育的许多方面，从而促进植物对环境变化做出系统反应的能力。阐明控制这些信号传导途径的分子机制对于理解植物的功能至关重要。结构和功能生物学方法对于解码植物遗传发现和揭示蛋白质水平的精确分子作用至关重要。过去对植物激素信号传导的研究尚未发现涉及高度协调的蛋白质更新以引起立即细胞反应的机制。许多植物激素信号传导途径依赖于泛素（Ub）蛋白酶体系统，特别是E3 Ub连接酶，以感知和引发信号传导。在这篇评论中
