A gravitropic stimulus alters the distribution of EHB1, a negative effector of root gravitropism in Arabidopsis

open access: yesPlant 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.

Sclerified Cork Outperforms the Exodermis: Root Water Permeability Decreases in the Soil‐To‐Canopy Transition of the Aroid Vine Epipremnum aureum

open access: yesPhysiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT The aroid vine Epipremnum aureum undergoes changes in habitat and growth axis direction from terrestrial (plagiotropic) to canopy (orthotropic) conditions. Since aerial roots connected to the forest soil are vital for water and nutrient uptake in these vines, we hypothesize that morphophysiological acclimation occurs, enabling root survival ...

LARGE ROOT ANGLE1, encoding OsPIN2, is involved in root system architecture in rice [PDF]

open access: yes, 2017
Root system architecture is very important for plant growth and crop yield. It is essential for nutrient and water uptake, anchoring, and mechanical support.

The Ca2+ pump inhibitor, thapsigargin, inhibits root gravitropism in Arabidopsis thaliana

open access: yesBiological Research, 2006
Thapsigargin, a specific inhibitor of most animal intracellular SERCA-type Ca2+ pumps present in the sarcoplasmic/endoplasmic reticulum, was originally isolated from the roots of the Mediterranean plant Thapsia gargancia L. Here, we demonstrate that this

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

open access: yesJournal 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-

The Photomorphogenic Central Repressor COP1: Conservation and Functional Diversification during Evolution

open access: yesPlant Communications, 2020
Green plants on the earth have evolved intricate mechanisms to acclimatize to and utilize sunlight. In Arabidopsis, light signals are perceived by photoreceptors and transmitted through divergent but overlapping signaling networks to modulate plant ...

Tailored for swift recognition: A structural perspective on secondary active plant hormone transporters

open access: yesThe Plant Journal, Volume 125, Issue 5, March 2026.
Significance Statement This review synthesizes current knowledge of plant hormone transporters across five major protein superfamilies. It links structural classification to transport mechanism and substrate specificity and demonstrates that this structural perspective provides a predictive framework for understanding substrate scope, selectivity ...

Circumnutation in the growth of Chara rhizoids

open access: yesActa Societatis Botanicorum Poloniae, 2014
Chara rhizoids, cylindrical cells growing in their apex, having the capability of positive orthogravitropic response, while growing without any change of position are not ideally straight, but they are characterised by slight and repeating cyclic ...

SMXL3 controls multiple aspects of Arabidopsis development via EAR motif‐dependent and ‐independent functions

open access: yesThe Plant Journal, Volume 125, Issue 5, March 2026.
SUMMARY SMAX1‐LIKE (SMXL) proteins, previously linked to strigolactone and karrikin signalling, play diverse and partially redundant roles in plant development. The divergent SMXL4 superclade—comprising SMXL3, SMXL4 and SMXL5—is not subject to strigolactone‐ or karrikin‐dependent proteolysis.

ZIFL1.1 transporter modulates polar auxin transport by stabilizing membrane abundance of multiple PINs inArabidopsisroot tip [PDF]

open access: yes, 2013
Cell-to-cell directional flow of the phytohormone auxin is primarily established by polar localization of the PIN auxin transporters, a process tightly regulated at multiple levels by auxin itself.
