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 ...

Molecular genetics of auxin signaling [PDF]
, 2002 The plant hormone auxin is a simple molecule similar to tryptophan, yet it elicits a diverse array of responses and is involved in the regulation of growth and development throughout the plant life cycle.

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)

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.

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.

Comparative effects of auxin and abscisic acid on growth, hydrogen ion efflux and gravitropism in primary roots of maize [PDF]
In order to test the idea that auxin action on root growth may be mediated by H(+) movement, the correlation of auxin action on growth and H(+) movement in roots was examined along with changes in H(+) efflux patterns associated with the asymmetric ...

Keeping it all together: auxin–actin crosstalk in plant development [PDF]
, 2015 Polar auxin transport and the action of the actin cytoskeleton are tightly interconnected, which is documented by the finding that auxin transporters reach their final destination by active movement of secretory vesicles along F-actin tracks.

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.

Suppression of asymmetric acid efflux and gravitropism in maize roots treated with auxin transport inhibitors of sodium orthovanadate [PDF]
In gravitropically stimulated roots of maize (Zea mays L., hybrid WF9 x 38MS), there is more acid efflux on the rapidly growing upper side than on the slowly growing lower side.

Plant Cognition—A Methodological Primer: Theories, Methods and Challenges
Philosophy Compass, Volume 20, Issue 12, December 2025.ABSTRACT Part I: What counts as cognition, and how can it be studied in organisms without nervous systems? The emerging field of plant cognition confronts these questions by integrating philosophy, plant science and comparative psychology. This article provides a methodological primer on the field.
