The plant hormone auxin regulates growth and development through at least two distinct signaling pathways. The nuclear pathway, involving TIR1/AFB receptors, mediates transcription; whereas the cell surface ABP1-TMK1 auxin perception triggers global ultrafast phosphorylation response. Here, we revisit the rich history of the disputed ABP1 auxin receptor, highlighting recent findings of the involvement of TMKs and other molecular components and focusing on their role in auxin canalization-mediated development.
植物激素生长素通过至少两条不同的信号通路调节生长和发育。涉及TIR1/AFB受体的核途径介导转录；而细胞表面的ABP1-TMK1生长素感知触发整体超快磷酸化反应。在这里，我们回顾了关于有争议的ABP1生长素受体的丰富历史，强调了TMKs和其他分子成分参与的最新发现，并关注它们在生长素通道化介导的发育中的作用。
