Article Synopsis
- Auxin influences plant growth through various signaling pathways, with a notable one being the SCF-Aux/IAA-ARF pathway, and a recently discovered noncanonical pathway involving Transmembrane Kinase 1 (TMK1).
- In apical hook development, auxin accumulation activates TMK1, leading to the phosphorylation and stabilization of IAA32/34, which ultimately inhibits cell elongation necessary for proper hook formation.
- The study identifies the CKRW1/WAV3 E3 ubiquitin ligases as key players in targeting IAA32/34 for degradation, with their activity being inhibited by TMK1c phosphorylation, thereby regulating the balance of cell elongation on different sides of the apical hook.
