Interactions of phototropism and gravitropism in cyanobacteria

Biophysical Journal
Abstract While gene expression in bacteria has been shown to be affected by near-zero or extremely high gravity, a mechanism has not been established to date. In larger organisms, gravity-sensing mechanisms usually rely on a dense body applying directional pressure which can be detected by the cell.

Collet Hairs Are Critical for Anchoring and Survival of Arabidopsis thaliana Seedlings During Early Development

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Rapid and successful establishment of seedlings, beginning with the penetration of the emerging radicle into the soil, is essential for survival. In roots, root hairs increase the surface area for the absorption of water and solutes while providing the mechanical anchorage necessary for deeper soil penetration during elongation.

Plant reactome knowledgebase : biocuration of genes and pathways involved in shoot gravitropism

Plant gravitropism is a complex process in which plants sense and respond to gravity by growing shoots upwards (negative gravitropism) and roots downwards (positive gravitropism).

Nitrate reductase mediates nitric oxide-dependent gravitropic response in Arabidopsis thaliana roots

Plant Signaling & Behavior, 2019
Plant roots respond positively to gravity force and orientate it growth providing anchorage to the soil and gathering water and nutrient sources. The gravitropic response is a complex process wherein nitric oxide (NO) participates as a key signaling ...

Small Signaling Peptides in Sorghum bicolor: Integrating Phylogeny and Gene Expression to Characterize Roles in Stem Development

Plant Direct, Volume 10, Issue 6, June 2026.
ABSTRACT Small signaling peptides (SSPs) are important regulators of plant growth, development, and responses to biotic and abiotic stress, yet their role in the C4 grass Sorghum bicolor is largely uncharacterized. To help fill this knowledge gap, 219 sorghum genes that encode SSPs were identified based on SSP sequences previously identified in ...

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 ...

Plant Peptides on the Rise: From Historical Insight to Future Applications

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3777-3802, June 2026.
ABSTRACT Plant peptides constitute a rapidly expanding class of signalling molecules essential to plant physiology, mediating key processes such as development, stress adaptation, and immune responses. This review traces the history of plant peptide research, from the seminal discovery of systemin to the recent identification of non‐canonical peptides (

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

, 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.

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
