🚨 New preprint by @cate-giannini.bsky.social🚨 We uncover an unexpected link between auxin signalling, transcription, and autophagy — revealing how plants coordinate gene expression and cytoplasmic renewal to drive developmental reprogramming. 🌱✨ www.biorxiv.org/content/10.1...

It is out! A tandem of two papers showing TMK regulation of PIN-dependent auxin transport www.cell.com/cell/fulltex... (PIN2, Friml lab) and www.cell.com/developmenta... (PIN1, Xu lab)

ABP1/ABL3-TMK1 cell-surface auxin signaling targets PIN2-mediated auxin fluxes for root gravitropism

In gravistimulated roots, gravity perception in the columella redirects the flow of the plant hormone auxin toward the lower root side, where it inhibits cell elongation for downward root bending. Thi...
