Regulation of Root Angle and Gravitropism [PDF]
G3 Genes|Genomes|Genetics, 2018 AbstractRegulation of plant root angle is critical for obtaining nutrients and water and is an important trait for plant breeding. A plant’s final, long-term root angle is the net result of a complex series of decisions made by a root tip in response to changes in nutrient availability, impediments, the gravity vector and other stimuli. When a root tip

A minus-end directed kinesin motor directs gravitropism in Physcomitrella patens
Nature Communications, 2021 Gravitropism is the process by which plants perceive and respond to gravity. Here the authors identify a minus-end-directed kinesin required for gravity-triggered actin filament rearrangement and negative gravitropic response in the moss Physcomitrella ...

PROG1 acts upstream of LAZY1 to regulate rice tiller angle as a repressor
Crop Journal, 2023 Rice tiller angle, as a component of plant architecture, affects rice grain yield via plant density. However, the molecular mechanism underlying rice tiller angle remains elusive.

The Role of Brassinosteroids in Shoot Gravitropism [PDF]
Plant Physiology, 2011 In the current model of gravitropism, negative gravitropic (upward) growth of the shoot of a dicotyledonous plant involves sedimentation of starch-containing plastids (statoliths) in the endodermis (starch sheath). Here we show that high levels of brassinosteroids (BRs) counteract gravitropic growth, while BR deficiency enhances gravitropism ...

Isolation of new gravitropic mutants under hypergravity conditions
Frontiers in Plant Science, 2016 Forward genetics is a powerful approach used to link genotypes and phenotypes, and mutant screening/analysis has provided deep insights into many aspects of plant physiology.

Gravity induces asymmetric Ca2+ spikes in the root cap in the early stage of gravitropism
Plant Signaling & Behavior, 2022 Gravitropism is an important strategy for the adaptation of plants to the changing environment. Previous reports indicated that Ca2+ participated in plant gravity response.

Gravity sensing, a largely misunderstood trigger of plant orientated growth
Frontiers in Plant Science, 2014 Gravity is a crucial environmental factor regulating plant growth and development. Plants have the ability to sense a change in the direction of gravity, which leads to the re-orientation of their growth direction, so-called gravitropism.

Molecular Mechanisms of Root Gravitropism [PDF]
Current Biology, 2017 Plant shoots typically grow against the gravity vector to access light, whereas roots grow downward into the soil to take up water and nutrients. These gravitropic responses can be altered by developmental and environmental cues. In this review, we discuss the molecular mechanisms that govern the gravitropism of angiosperm roots, where a physical ...
