Investigating the Role of Small RNA Pathways in Arabidopsis Shoot Gravitropism

, 2022
The plant stem grows against the gravitational force, a phenomenon called negative gravitropism. In the model dicotyledonous plant Arabidopsis thaliana, gravity is sensed by starch-filled amyloplasts, which trigger the shoot gravitropic response through ...

Gravity induces asymmetric Ca²⁺ spikes in the root cap in the early stage of gravitropism

, 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.

Plant subtilases as key initiators of peptide ligand‐receptor signaling

The Plant Journal, Volume 126, Issue 1, April 2026.
SUMMARY Peptide ligand‐receptor signaling plays a crucial role in regulating diverse biological processes in plants. Over the past three decades, numerous peptide ligands and their corresponding receptors have been identified, and our understanding of their downstream signaling pathways and biological functions has gradually advanced.

Plants and Graviperception [PDF]

فناوری در مهندسی هوافضا, 2019
Plants have different mechanisms for understanding and responding to environmental stimuli cues. Gravity is one of the most important directional environmental cues to control growth direction, that plants can permanently adapt to it. Gravitropism can be

Discrete and cell‐specific hypoxic responses in Arabidopsis roots resolved by single‐nuclei transcriptomics

New Phytologist, Volume 249, Issue 6, Page 2652-2667, March 2026.
Summary With the intensification of unpredictable flooding events because of global warming, there is a need to understand how root cells perceive and respond to oxygen deprivation. The use of high‐throughput single‐nuclei RNA‐sequencing (snRNA‐Seq) allows the examination of gene expression profiles in discrete cell types.

Anatomical changes of xylem cells in stem of Pinus radiata seedlings exposed to inclination and ethylene

Biologia Plantarum, 2013
In conifers, relationship between ethylene and the response to inclination are not well understood. The aim of this work was to study the consequence for the application of 2-chloroethyl phosphonic acid (ethephon), compound able to release ethylene, in ...

Effects of a hypogeomagnetic field on gravitropism and germination in soybean

, 2011
Any plants grown during long-term space missions will inevitably experience an extremely low magnetic field (i.e. a hypogeomagnetic field, HGMF). It is possible that the innate adaptation of plants to the earth’s magnetic field (i.e.

A method for the quantification of phototropic and gravitropic sensitivities of plants combining an original experimental device with model-assisted phenotyping: Exploratory test of the method on three hardwood tree species.

PLoS ONE, 2019
Perception of inclination in the gravity field and perception of light direction are two important environmental signals implicated in the control of plant shape and habit. However, their quantitative study in light-grown plants remains a challenge.

Hook formation in sunflower seedlings is directed by both positive gravitropism and a form of circumnutation

, 1998
The apical hook that forms at the apex of most dicotyledonous seedlings during germination has in the past been variously described either as the consequence of positive gravitropism or as an autonomous process.
