The phytohormone auxin is a pivotal signaling molecule that functions throughout the plant lifecycle. Proper regulation of the auxin response is critical for optimizing plant growth under ever-changing environmental conditions. Recent studies have demonstrated that the signaling components that modulate auxin sensitivity and responses are functionally and mechanically diverse. In addition to auxin itself, various environmental and hormonal signals are integrated to modulate the auxin response through directly controlling auxin signaling components. This review explores the non-canonical mechanisms that modulate auxin signaling components, including transcriptional, translational, and post-translational regulation. All of these contribute to the wide range in sensitivity and complexity in auxin responses to various signaling cues.
植物激素生长素是一种关键的信号分子，它在植物生命周期中发挥作用。生长素响应的适当调节对于在不断变化的环境条件下优化植物生长至关重要。最近的研究表明，调节生长素敏感性和响应的信号成分在功能和机械上是多样化的。除了生长素本身，各种环境和激素信号被整合在一起，通过直接控制生长素信号成分来调节生长素响应。本综述探讨了调节生长素信号成分的非经典机制，包括转录、翻译和翻译后调节。所有这些都有助于生长素对各种信号的响应的敏感性和复杂性的广泛差异。
