Shoot gravitropism and organ straightening cooperate to arrive at a mechanically favorable shape in Arabidopsis [PDF]
Scientific Reports, 2023 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 simultaneously around the inflorescence stem tip.

An auxin response factor regulates tiller angle and shoot gravitropism by directly activating related gene expression in rice [PDF]
Journal of Advanced ResearchIntroduction: The angle of tillers is crucial for shaping plant architecture, which in turn affects grain yield of rice. The formation of tiller angle is associated with the asymmetrical distribution and polar transport of auxin.

A Unifying Modeling of Plant Shoot Gravitropism With an Explicit Account of the Effects of Growth [PDF]
Frontiers in Plant Science, 2014 Gravitropism, the slow reorientation of plant growth in response to gravity, is a major determinant of the form and posture of land plants. Recently a universal model of shoot gravitropism, the AC model, has been presented, in which the dynamics of the ...

Blocking Rice Shoot Gravitropism by Altering One Amino Acid in LAZY1 [PDF]
International Journal of Molecular Sciences, 2022 Tiller angle is an important trait that determines plant architecture and yield in cereal crops. Tiller angle is partially controlled during gravistimulation by the dynamic re-allocation of LAZY1 (LA1) protein between the nucleus and plasma membrane, but the underlying mechanism remains unclear.

Elucidating the Genetic Basis of Columnar Upright Architecture in Populus Through CRISPR Disruption of TILLER ANGLE CONTROL1. [PDF]
Plant Biotechnol JABSTRACT Narrow or upright branch angles in shoots and leaves lead to columnar, upright‐growing tree architectures, as observed in various tree species such as Lombardy poplar (Populus nigra var. italica). However, the genetic mechanism underlying this unique growth habit in Lombardy poplar has not yet been elucidated.
