Live tracking of moving samples in confocal microscopy for vertically grown roots

eLife, 2017
Roots navigate through soil integrating environmental signals to orient their growth. The Arabidopsis root is a widely used model for developmental, physiological and cell biological studies.

Gravitropism mechanisms in single-celled organs and multicellular organs of plants

, 2022
Plants react to various environmental stimuli by oriented growth. The growth responses are called tropisms. Gravitropism is a directed growth concerning the gravity vector. Plant shoots grow up, negatively gravitropically, to catch the light.

Interaction with gravitropism, reversibility and lateral movements of phototropically stimulated potato shoots [PDF]

, 2016
Phototropic (PT) and gravitropic (GT) bending are the two major tropic movements that determine the spatial position of potato shoots. We studied PT bending of potato plantlets grown under long-day photoperiods in several prearranged position setups ...

Brassinosteroid control of shoot gravitropism interacts with ethylene and depends on auxin signaling components

, 2013
Premise of the study: To reach favorable conditions for photosynthesis, seedlings grow upward when deprived of light upon underground germination. To direct their growth, they use their negative gravitropic capacity.

Regulation of tiller angle by gravity-sensing genes in rice

Crop Journal
Endodermal cells and starch-accumulating amyloplasts are well-known gravity sensors initiating shoot gravitropism in Arabidopsis thaliana. The transcription factors SHR and SGR1 regulate endodermal cell formation, while PGM has been demonstrated to ...

Combining phosphoproteomics and high-throughput phenotyping for the identification of gravitropism-related proteins in Arabidopsis thaliana

, 2023
Gravitropism is a fundamental process in plants that allows shoots to grow upward and roots to grow downward. Protein phosphorylation has been postulated to participate in the intricate signaling cascade of gravitropism.

RCN1-Regulated Phosphatase Activity and EIN2 Modulate Hypocotyl Gravitropism by a Mechanism That Does Not Require Ethylene Signaling

, 2006
The roots curl in naphthylphthalamic acid1 (rcn1) mutant of Arabidopsis (Arabidopsis thaliana) has altered auxin transport, gravitropism, and ethylene response, providing an opportunity to analyze the interplay between ethylene and auxin in control of ...

Peg Biology: Deciphering the Molecular Regulations Involved During Peanut Peg Development

Frontiers in Plant Science, 2019
Peanut or groundnut is one of the most important legume crops with high protein and oil content. The high nutritional qualities of peanut and its multiple usage have made it an indispensable component of our daily life, in both confectionary and ...

The role of Arabidopsis Actin-Related Protein 3 in amyloplast sedimentation and polar auxin transport in root gravitropism

, 2016
Arabidopsis actin-related protein ARP3 plays a role in amyloplast sedimentation and polar auxin redistribution during root gravitropism.Gravitropism is vital for shaping directional plant growth in response to the forces of gravity.

Ethylene biosynthesis and its actions in Arabidopsis thaliana shoot gravitropism

, 2000
The olefin gas ethylene, as one of the five major classes of plant hormones, has a wide range of physiological effects on plants. The production of ethylene by plants is tightly regulated and cannot be uncoupled from its actions.
