CsLAZY1 mediates shoot gravitropism and branch angle in tea plants (Camellia sinensis) [PDF]

BMC Plant Biology, 2021
Background Branch angle is a pivotal component of tea plant architecture. Tea plant architecture not only affects tea quality and yield but also influences the efficiency of automatic tea plant pruning.

Inclination not force is sensed by plants during shoot gravitropism. [PDF]

Sci Rep, 2016
International audienceGravity perception plays a key role in how plants develop and adapt to environmental changes. However, more than a century after the pioneering work of Darwin, little is known on the sensing mechanism.

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 ...

Sucrose and Mannans Affect Arabidopsis Shoot Gravitropism at the Cell Wall Level [PDF]

Plants
Gravitropism is the plant organ bending in response to gravity. Gravitropism, phototropism and sufficient mechanical strength define the optimal position of young shoots for photosynthesis.

A mathematical model explores the contributions of bending and stretching forces to shoot gravitropism in Arabidopsis [PDF]

Quantitative Plant Biology, 2020
Plant shoot gravitropism is a complex phenomenon resulting from gravity sensing, curvature sensing (proprioception), the ability to uphold self-weight and growth.

Blocking Rice Shoot Gravitropism by Altering One Amino Acid in LAZY1. [PDF]

Int J Mol Sci, 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.

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.

Adaptive divergence in shoot gravitropism creates hybrid sterility in an Australian wildflower. [PDF]

Proc Natl Acad Sci U S A, 2021
Significance New species originate as populations become reproductively isolated from one another. Despite recent progress in uncovering the genetic basis of reproductive isolation, it remains unclear whether intrinsic reproductive barriers, such as hybrid sterility, can evolve as a by-product of local adaptation to contrasting ...

An auxin response factor regulates tiller angle and shoot gravitropism by directly activating related gene expression in rice [PDF]

Journal of Advanced Research
Introduction: 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.
