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 ...

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.

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

Gravity-Sensing Tissues for Gravitropism Are Required for “Anti-Gravitropic” Phenotypes of lzy Multiple Mutants in Arabidopsis

Plants, 2020
Plant posture is controlled by various environmental cues, such as light, temperature, and gravity. The overall architecture is determined by the growth angles of lateral organs, such as roots and branches.

Auxins and environmental factors regulate root gravitropism

Biologia Plantarum
Roots are important for plant anchoring, water and nutrient absorption, and other physiological processes. Gravity is a primary determinant of the spatial distribution of plant roots in the soil.

Stem gravitropism and tension wood formation in three tropical woody species with different wood densities

Journal of Wood Science
Angiosperm trees develop tension wood on the upper side of leaning stems to reorient the direction of stems towards their normal positions in response to a gravitational stimulus. The development of gelatinous fibers with thick inner gelatinous layers (G-

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

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 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.

Root Gravitropism: Quantification, Challenges, and Solutions [PDF]

, 2018
Better understanding of root traits such as root angle and root gravitropism will be crucial for development of crops with improved resource use efficiency. This chapter describes a high-throughput, automated image analysis method to trace Arabidopsis (Arabidopsis thaliana) seedling roots grown on agar plates.
