AFB1 controls rapid auxin signalling through membrane depolarization in Arabidopsis thaliana root.

Nature plants - 1 Sept 2021

Abstract excerpt

The membrane potential reflects the difference between cytoplasmic and apoplastic electrical potentials and is essential for cellular operation. The application of the phytohormone auxin (3-indoleacetic acid (IAA)) causes instantaneous membrane depolarization in various cell types1-6, making depolarization a hallmark of IAA-induced rapid responses. In root hairs, depolarization requires functional IAA transport...
