Stomatal trait variation may have evolved more in response to pathogens than climate, or climate may be affecting the traits in unexpected ways.

Urban environments and climate change: how do we choose resilient urban trees for the future?
On a hot day in the city, the shade under a leafy tree can be a welcome relief from the sun. But can you imagine if you looked around and there were no trees in sight? Or the only trees you can see are either dead or...

Root hairs offer benefit during drought without decreasing yield in good years
This makes them an ideal target for breeders looking to up resilience without bringing down productivity.
PtHMGR overexpression enhances tolerance of salt and drought
Overexpression of PtHMGR enhanced the stress resistance of poplar.

Potential involvement of root auxins in drought tolerance by modulating nocturnal and daytime water use in wheat
The ability of wheat genotypes to save water by reducing their transpiration rate (TR) at times of the day with high vapour pressure deficit (VPD) has been linked to increasing yields in terminal drought environments...

Trait divergence determines the success of a newly invasive plant
It is often assumed that the ability of plants to acclimatize to the local environment through non-genetic changes in their anatomy and physiology (phenotypic plasticity) is important for the success of invasive species...
Potential risk of photo-damage in Antarctic photosynthetic organisms
Light is indispensable for photosynthetic organisms, but excess light energy causes damage in photosystems and readily leads to cell death in severe environments such as Antarctica. Kosugi et al. determine reaction...
Interactive effects of [CO2] and water availability on maritime pine
Evidence from this study indicates that elevated [CO2] not only can aggravate the effects of water deficit on photosynthetic performance and growth of maritime pine but also it can attenuate genotypic differences in...

Predicting habitat affinities with drought tolerance traits in herbaceous dicots
Soil water availability is an important mechanism filtering plant species. Twenty-five herbaceous dicot species were grown under controlled conditions in order to measure a suite of physiological traits associated with...
Antarctic endophytes improve drought tolerance in lettuce plants
Climate change has limited the availability of water for irrigating crops throughout many regions of the world. Indeed, current models of climate change predict that arid and semi-arid zones will be places where...

Deep roots and their functions in ecosystems
Deep roots determine many ecosystem services but remain understudied, due to the challenges involved in the observation and measurement of deep roots. In this paper, Pierret et al. show that root structures and...
Brachypodium peroxidase and drought tolerance
The peroxidase (POD) family shows functional diversity. Luo et al. demonstrate that Brachypodium distachyon ecotypes have distinct specific POD isozymes. Two POD genes are closely associated with whole-plant response to...
Conflicting genomic signals affect phylogenetic inference in four species of North American pines
Pines (genus Pinus) are among the most ecologically and economically important plant species. Some, such as the pines of the southeastern USA (southern pines in subsection Australes), are the subject of intensive...
Epigenetics of drought-induced trans-generational plasticity; consequences for range limit development
Offspring phenotypes may be altered by environments that their parents lived in.These environmentally-induced trans-generational effects may be mediated by epigenetic mechanisms such as DNA methylation. Little is known...
