- W2282259480 abstract "Gravitropic bending of plant organs is mediated by formation of an auxin gradient between the upper and lower side of the respective organ. Studies in monocot shoots suggested that besides auxin also gibberellin (GA) shows asymmetric distribution during gravitropism, but the functional relevance of this observation remains unclear. Here we addressed a role of GA in root gravitropism of Arabidopsis thaliana by genetically and pharmacologically manipulating GA metabolism and signaling. We show that manipulations of GA content and response in the root affect both auxin distribution during gravitropism and gravitropic response. Immunostaining using an antibody directed against GA detected asymmetry of GA distribution in the root tip during the gravitropic response. We observed that GA treatments specifically increased plasma membrane amounts of PIN auxin transporters independent of transcriptional regulation suggesting that GA affects root auxin distribution by stabilization of the gravitropic regulator PIN2. Manipulations of GA levels or GA signaling affected intracellular PIN2 accumulation in response to the trafficking inhibitor Brefeldin A. We propose that the observed increase in PIN2 stability may be due to a GA effect on the retromer complex causing enhanced recycling of PIN2 from the prevacuolar compartment to the trans-Golgi network with the consequence of less PIN2 trafficking to the lytic vacuole." @default.
