The architecture of resilience: a genome assembly of Myrothamnus flabellifolia sheds light on desiccation tolerance and sex determination

open access: yesNew Phytologist, Volume 249, Issue 2, Page 1063-1084, January 2026.
Summary Myrothamnus flabellifolia is a dioecious resurrection plant endemic to southern Africa that has become an important model for understanding desiccation tolerance. Despite its ecological and medicinal significance, genomic and transcriptomic resources for the species are limited.

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

open access: yesPhilosophy 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.

Palisade cell shape affects the light-induced chloroplast movements and leaf photosynthesis [PDF]

open access: yes, 2018
Leaf photosynthesis is regulated by multiple factors that help the plant to adapt to fluctuating light conditions. Leaves of sun-light-grown plants are thicker and contain more columnar palisade cells than those of shade-grown plants.

PHOTOTROPISM OF DIXIPPUS MOROSUS [PDF]

open access: yesJournal of General Physiology, 1928
1. Local differences in the effects of stimulation of parts of the eye by light are expressed in Dixippus morosus by differential circus movements. 2. The angle of inclination of the body axis toward one source of light when the animal is on a vertical plane with light from one side is inversely proportional to the logarithm of the ...

Role of Leaves in Phototropism [PDF]

open access: yesPlant Physiology, 1966
Experiments with green seedlings of sunflower (Helianthus annuns L.) indicate the existence of a phototropic mechanism which involves the leaves or cotyledons, and which can produce an asymmetry of auxin content without the involvement of lateral auxin transport, the classic explanation of phototropism in etiolated seedlings.

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.

open access: yesPLoS 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.

Magnetic field effects on plant growth, development and evolution

open access: yesFrontiers in Plant Science, 2014
The geomagnetic field (GMF) is a natural component of our environment. Plants, which are known to sense different wavelengths of light, respond to gravity, react to touch and electrical signaling, cannot escape the effect of GMF.

Phototropins of the moss Physcomitrella patens function as blue-light receptors for phototropism in Arabidopsis

open access: yesPlant Signalling & Behavior, 2018
Four phototropin genes (PHOTA1, PHOTA2, PHOTB1, PHOTB2) have been isolated in the moss Physcomitrella patens. These genes encode phototropins that mediate blue-light–induced chloroplast movement.

Abstracting Hopper

open access: yesTextes & Contextes, 2019
One of the most seductive aspects of Hopper paintings is the sheer visual potency of their painted surface, the lavish formal trap of line and color that the artist has composed.

The Alpha-Helix Concept: Innovative utilization of the Space Station Program. A report to the National Aeronautical and Space Administration requesting establishment of a Sensory Physiology Laboratory on the Space Station [PDF]

open access: yes
A major laboratory dedicated to biological-medical research is proposed for the Space Platform. The laboratory would focus on sensor physiology and biochemistry since sensory physiology represents the first impact of the new space environment on living ...
