SGR1, SGR2, and SGR3: Novel Genetic Loci Involved in Shoot Gravitropism in Arabidopsis thaliana [PDF]

Plant Physiology, 1996
In higher plants shoots show a negative gravitropic response but little is known about its mechanism. To elucidate this phenomenon, we have isolated a number of mutants with abnormal shoot gravitropic responses in Arabidopsis thaliana. Here we describe mainly three mutants: sgr1-1, sgr2-1, and sgr3-1 (shoot gravitropism).

Peptide signaling at the intersection of growth, nutrient sensing, and stress responses

The Plant Journal, Volume 125, Issue 4, February 2026.
SUMMARY Plant endogenous peptides emerge as central regulators of multiple aspects of plant physiology. They are secreted from cells and perceived by plasma membrane localized receptors, which activate downstream signaling pathways to regulate growth and development. In addition, endogenous peptides coordinate physiology with their environment.

Underground roots monitor aboveground environment by sensing stem-piped light

Communicative & Integrative Biology, 2016
Light is a critical environmental cue for plant growth and development. Plants actively monitor surrounding environments by sensing changes in light wavelength and intensity.

Phototropism: Translating light into directional growth. [PDF]

, 2012
Phototropism allows plants to align their photosynthetic tissues with incoming light. The direction of incident light is sensed by the phototropin family of blue light photoreceptors (phot1 and phot2 in Arabidopsis), which are light-activated protein ...

A simple and versatile 2-dimensional platform to study plant germination and growth under controlled humidity [PDF]

, 2014
We describe a simple, inexpensive, but remarkably versatile and controlled growth environment for the observation of plant germination and seedling root growth on a flat, horizontal surface over periods of weeks.

The Effector RipAW Enhances Ralstonia solanacearum Invasion in Arabidopsis via CBP60g/SARD1‐Dependent and ‐Independent Pathways

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
The effector RipAW facilitates R. solanacearum infection by suppressing CBP60g/SARD1‐dependent SA pathway and triggering CBP60g/SARD1‐independent root architecture changes. ABSTRACT CaM‐binding Protein 60‐like G (CBP60g) and Systemic Acquired Resistance Deficient 1 (SARD1) are key immune signalling regulators that redundantly promote salicylic acid (SA)

ACCERBATIN, a small molecule at the intersection of auxin and reactive oxygen species homeostasis with herbicidal properties [PDF]

, 2017
The volatile two-carbon hormone ethylene acts in concert with an array of signals to affect etiolated seedling development. From a chemical screen, we isolated a quinoline carboxamide designated ACCERBATIN (AEX) that exacerbates the 1-aminocyclopropane-1-

Plant Cognition—An Empirical Primer: Evidence, Implications, and Ethics

Philosophy Compass, Volume 21, Issue 1, January/February 2026.
ABSTRACT Recent advances in plant biology suggest that plants engage in complex behaviours once thought to require nervous systems. This article surveys the empirical foundations of plant cognition, covering research on goal‐directed movement, decision‐making, anticipatory behaviour, communication, phytoacoustics, and plant neurobiology.

Genetic dissection of the root system architecture QTLome and its relationship with early shoot development, breeding and adaptation in durum wheat

The Plant Genome, Volume 18, Issue 4, December 2025.
Abstract Root system architecture (RSA), shoot architecture, and shoot‐to‐root biomass allocation are critical for optimizing crop water and nutrient capture and ultimately grain yield. Nevertheless, only a few studies adequately dissected the genetic basis of RSA and its relationship to shoot development.

Gravitropism in plants: Hydraulics and wall growth properties of responding cells [PDF]

Gravitropism is the asymmetrical alteration of plant growth in response to a change in the gravity vector, with the typical result that stems grow up and roots grow down.
