Leveraging orthology within maize and Arabidopsis QTL to identify genes affecting natural variation in gravitropism

, 2022
Plants typically orient their organs with respect to the Earth's gravity field by a dynamic process called gravitropism. To discover conserved genetic elements affecting seedling root gravitropism, we measured the process in a set of Zea mays (maize ...

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

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.

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 ...

Functional mapping of gravitropism and phototropism for a desert tree, Populus euphratica

Frontiers in Bioscience-Landmark, 2021
Background: Plants have evolved the dual capacity for maximizing light assimilation through stem growth (phototropism) and maximizing water and nutrient absorption through root growth (gravitropism).

A functional TOC complex contributes to gravity signal transduction in Arabidopsis

Frontiers in Plant Science, 2014
Although plastid sedimentation has long been recognized as important for a plant’s perception of gravity, it was recently shown that plastids play an additional function in gravitropism. The Translocon at the Outer envelope membrane of Chloroplasts (TOC)

Calcium in the Regulation of Gravitropism by Light [PDF]

Plant Physiology, 1988
The red light requirement for positive gravitropism in roots of corn (Zea mays cv "Merit") provides an entry for examining the participation of calcium in gravitropism. Applications of calcium chelators inhibit the light response. Calcium channel blockers (verapamil, lanthanum) can also inhibit the light response, and a calcium ionophore, A23187, can

Diagram explaining the interactions between gravitropism and phototropism in classical experiments dedicated to the study of gravitropism and phototropism.

, 2019
A: In classical experiments, a plant is tilted from the vertical in order to study gravitropism. In this case, since the light is coming from the top, one side of the stem is shaded, which can induce a phototropic reaction. B: In classical experiments, a

Distribution of Endogenous NO Regulates Early Gravitropic Response and PIN2 Localization in Arabidopsis Roots

Frontiers in Plant Science, 2018
High-resolution and automated image analysis of individual roots demonstrated that endogenous nitric oxide (NO) contribute significantly to gravitropism of Arabidopsis roots.
