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.

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.

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 ...

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.

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.

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 ...

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 ...

Rapid translocation of NGR proteins driving polarization of PIN-activating D6 protein kinase during root gravitropism

eLife
Root gravitropic bending represents a fundamental aspect of terrestrial plant physiology. Gravity is perceived by sedimentation of starch-rich plastids (statoliths) to the bottom of the central root cap cells.
