A Conditional Mutation in SCD1 Reveals Linkage Between PIN Protein Trafficking, Auxin Transport, Gravitropism, and Lateral Root Initiation

Frontiers in Plant Science, 2020
Auxin is transported in plants with distinct polarity, defined by transport proteins of the PIN-formed (PIN) family. Components of the complex trafficking machinery responsible for polar PIN protein localization have been identified by genetic approaches,

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 ...

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

Biological 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

Journal 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-

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 (

Circumnutation in the growth of Chara rhizoids

Acta 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 ...

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

Plant 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 ...

Auxins and environmental factors regulate root gravitropism

Biologia Plantarum
Roots are important for plant anchoring, water and nutrient absorption, and other physiological processes. Gravity is a primary determinant of the spatial distribution of plant roots in the soil.
