Ethylene signaling increases reactive oxygen species accumulation to drive root hair initiation in Arabidopsis.

Development (Cambridge, England) - 1 Jul 2022

Abstract excerpt

Root hair initiation is a highly regulated aspect of root development. The plant hormone ethylene and its precursor, 1-amino-cyclopropane-1-carboxylic acid, induce formation and elongation of root hairs. Using confocal microscopy paired with redox biosensors and dyes, we demonstrated that treatments that elevate ethylene levels lead to increased hydrogen peroxide accumulation in hair cells prior to root hair...
