Flowers underpin plant evolution, genetic legacy and global food supply. They are exposed to similar evaporative conditions as leaves, yet floral physiology is a product of different selective forces. We used Tanacetum cinerariifolium, a perennial daisy, to examine the…
The evolution of terrestrial plants capable of growing upwards into the dry atmosphere profoundly transformed the Earth. A transition from small, ‘non-vascular’ bryophytes to arborescent vascular plants during the Devonian period is partially attributed to the evolutionary innovation…
Efficient water transport from soil to leaves sustains stomatal opening and steady‐state photosynthesis. The aboveground portion of this pathway is well‐described, yet the roots and their connection with the soil are still poorly understood due to technical limitations….
Trees are the living foundations on which most terrestrial biodiversity is built. Central to the success of trees are their woody bodies, which connect their elevated photosynthetic canopies with the essential belowground activities of water and nutrient acquisition….
Identifying the drivers of stomatal closure and leaf damage during stress in grasses is a critical prerequisite for understanding crop resilience. Here, we investigated whether changes in stomatal conductance (gs) during dehydration were associated with changes in leaf…
Eighty barley (Hordeum vulgare L.) genotypes of different geographical origin and contrasting in salinity stress tolerance were grown under glasshouse conditions and exposed to high salinity stress (300 mM NaCl) for four weeks to investigate the relationship between leaf gas…Download
Background: While most water loss from leaf surfaces occurs via stomata, part of this loss also occurs through the leaf cuticle, even when the stomata are fully closed. This component, termed residual transpiration, dominates during the night and…Download
Plant breeders are in the need for a convenient, reproducible, reliable and rapid screening methods to be used as a proxy for drought tolerance for a large number of genotypes. Addressing this need, we compared different physiological measures…Download
A simple model combining leaf hydraulics and abscisic acid 23 sensitivity can predict stomatal dynamics to short-term changes in plant water status in a conifer.Download
Water stress is known to cause xylem cavitation in the leaves, roots and stems of plants, but little is known about the vulnerability of flowers to xylem damage during drought. This is an important gap in our understanding…Download
