The RGI1–BAK1 module acts as the main receptor–coreceptor pair for regulating primary root gravitropism and meristem activity in response to RGF1 peptide in Arabidopsis [PDF]
Plant Signaling & Behavior, 2023 ROOT MERISTEM GROWTH FACTOR1 (RGF1) and its receptors RGF1 INSENSITIVEs (RGIs), a group of leucine-rich repeat receptor kinases, promote primary root meristem activity via a mitogen-activated protein kinase (MPK) signaling cascade and control root ...

A gravitropic stimulus alters the distribution of EHB1, a negative effector of root gravitropism in Arabidopsis [PDF]
Plant Direct, 2020 In Arabidopsis gravitropism is affected by two antagonistically interacting proteins, AGD12 (ADP‐RIBOSYLATION FACTOR GTPase‐ACTIVATING PROTEIN) and EHB1 (ENHANCED BENDING 1). While AGD12 enhances gravitropic bending, EHB1 functions as a negative element.

Sucrose and Mannans Affect Arabidopsis Shoot Gravitropism at the Cell Wall Level [PDF]
PlantsGravitropism is the plant organ bending in response to gravity. Gravitropism, phototropism and sufficient mechanical strength define the optimal position of young shoots for photosynthesis.

TOP1α suppresses lateral root gravitropism in Arabidopsis
Plant Signaling & Behavior, 2022 Root gravitropism is important for anchorage and exploration of soil for water and nutrients. It affects root architecture, which is one of the elements that influence crop yield. The mechanism of primary root gravitropism has been widely studied, but it

LAZY Gene Family in Plant Gravitropism
Frontiers in Plant Science, 2021 Adapting to the omnipresent gravitational field was a fundamental basis driving the flourishing of terrestrial plants on the Earth. Plants have evolved a remarkable capability that not only allows them to live and develop within the Earth’s gravity field,

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 ...

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.

Stochastic processes in gravitropism [PDF]
, 2014 In this short review we focus on the role of noise in gravitropism of plants – the reorientation of plants according to the direction of gravity. We briefly introduce the conventional picture of static gravisensing in cells specialized in sensing.

Asymmetric cytokinin signaling opposes gravitropism in roots [PDF]
Journal of Integrative Plant Biology, 2020 Plants depend on gravity to provide the constant landmark for downward root growth and upward shoot growth. The phytohormone auxin and its cell‐to‐cell transport machinery are central determinants ensuring gravitropic growth.
