Open AccessShoot gravitropism and organ straightening cooperate to arrive at a mechanically favorable shape in Arabidopsis
Gravitropism is the plant organ bending in response to gravity, while a straightening mechanism prevents bending beyond the gravitropic set-point angle. The promotion and prevention of bending occur simultaneo...

Open AccessDesign and synthesis of strong root gravitropism inhibitors with no concomitant growth inhibition
Herein, we describe a highly potent gravitropic bending inhibitor with no concomitant growth inhibition. Previously, we reported that (2Z,4E)-5-phenylpenta-2,4-dienoic acid (ku-76) selectively inhibits root gravi...

Open AccessConnected function of PRAF/RLD and GNOM in membrane trafficking controls intrinsic cell polarity in plants
Cell polarity is a fundamental feature underlying cell morphogenesis and organismal development. In the Arabidopsis stomatal lineage, the polarity protein BASL controls stomatal asymmetric cell division. However,...

Open AccessPolar recruitment of RLD by LAZY1-like protein during gravity signaling in root branch angle control
In many plant species, roots maintain specific growth angles relative to the direction of gravity, known as gravitropic set point angles (GSAs). These contribute to the efficient acquisition of water and nutri...

Open AccessTranscriptional regulation of PIN genes by FOUR LIPS and MYB88 during Arabidopsis root gravitropism
PIN proteins are auxin export carriers that direct intercellular auxin flow and in turn regulate many aspects of plant growth and development including responses to environmental changes. The Arabidopsis R2R3-MYB...

Erratum: Regulation of organ straightening and plant posture by an actin–myosin XI cytoskeleton
Nature Plants 1, 15031 (2015); published online 23 March 2015; corrected 14 April 2015. In the version of the Supplementary Information originally published several characters in Fig. 4 were rendered incorrect...

Regulation of organ straightening and plant posture by an actin–myosin XI cytoskeleton
Plants are able to bend nearly every organ in response to environmental stimuli such as gravity and light1,2. After this first phase, the responses to stimuli are restrained by an independent mechanism, or even r...

Live Cell Imaging of Cytoskeletal and Organelle Dynamics in Gravity-Sensing Cells in Plant Gravitropism
Plants sense gravity and change their morphology/growth direction accordingly (gravitropism). The early process of gravitropism, gravity sensing, is supposed to be triggered by sedimentation of starch-filled p...
