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
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]
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]
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]
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.

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
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.

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.

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]
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 ...
