A class I ADP-ribosylation factor GTPase-activating protein is critical for maintaining directional root hair growth in Arabidopsis.

Plant physiology - 1 Aug 2008

Yoo Cheol-Min, Wen Jiangqi, Motes Christy M, Sparks J Alan, Blancaflor Elison B

Abstract excerpt

Membrane trafficking and cytoskeletal dynamics are important cellular processes that drive tip growth in root hairs. These processes interact with a multitude of signaling pathways that allow for the efficient transfer of information to specify the direction in which tip growth occurs. Here, we s...
