Stochastic processes in gravitropism [PDF]

Frontiers in Plant Science, 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.

LAZY Gene Family in Plant Gravitropism [PDF]

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,

Negative gravitropic response of roots directs auxin flow to control root gravitropism [PDF]

Plant, Cell & Environment, 2019
AbstractRoot tip is capable of sensing and adjusting its growth direction in response to gravity, a phenomenon known as root gravitropism. Previously, we have shown that negative gravitropic response of roots (NGR) is essential for the positive gravitropic response of roots.

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

EARLY STARVATION 1 Is a Functionally Conserved Protein Promoting Gravitropic Responses in Plants by Forming Starch Granules

Frontiers in Plant Science, 2021
Starch granules in the endodermis of plant hypocotyls act as statoliths that promote hypocotyl negative gravitropism—the directional growth of hypocotyls against gravity—in the dark.

Microarray analyses and comparisons of upper or lower flanks of rice shoot base preceding gravitropic bending. [PDF]

PLoS ONE, 2013
Gravitropism is a complex process involving a series of physiological pathways. Despite ongoing research, gravitropism sensing and response mechanisms are not well understood.

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 ...

Plant Root Architectural Traits Mediate a Trade-Off Between Suppression and Tolerance of Competitors. [PDF]

Ecol Evol
We use a modelling approach to simulate the evolution of root architecture under increasing levels of competition. An increase in the number of neighbours results in the evolution of roots that grow deeper and are less dense, causing plants to have lower maximum fitness but increased competition tolerance.

Springback in Root Gravitropism [PDF]

Plant Physiology, 1989
Conditions under which a gravistimulus of Merit corn roots (Zea mays L.) is withdrawn result in a subsequent loss of gravitropic curvature, an effect which we refer to as springback.' This loss of curvature begins within 1 to 10 minutes after removal of the gravistimulus. It occurs regardless of the presence or absence of the root cap.
