GNOM regulates root hydrotropism and phototropism independently of PIN-mediated auxin transport.

Plant science : an international journal of experimental plant biology - 1 Feb 2014

Abstract excerpt

Plant roots exhibit tropisms in response to gravity, unilateral light and moisture gradients. During gravitropism, an auxin gradient is established by PIN auxin transporters, leading to asymmetric growth. GNOM, a guanine nucleotide exchange factor of ARF GTPase (ARF-GEF), regulates PIN localization by regulating subcellular trafficking of PINs. Therefore, GNOM is important for gravitropism. We previously isolated...
