No acclimation: flexible responses of photosynthesis to different temperatures in American elm
Will photosynthetic processes of trees be able to keep up with future changes in temperature and precipitation under climate change?
Venus flytraps meet post-capture energy needs with cyclic electron transport
A switch from linear to cyclic electron transport provides the extra boost needed until energy can be taken up from the insect itself.

Night-time transpiration facilitates respiratory carbon dioxide release
Night-time transpiration accounts for a considerable amount of water loss in crop plants, yet its biological function, regulation and response to salt stress are poorly understood. Even et al. present data on barley...

Fueling the fire – how is stem growth respiration linked to stem growth?
Understanding how forests grow and how they metabolize carbon is crucial to ecosystem carbon flux, feedbacks between vegetation and climate, and the forestry. However, a key question remains unanswered: how is carbon...

Waterlogging tolerance in the forage legume Melilotus siculus
Messina (Melilotus siculus, Fabaceae) is a waterlogging-tolerant annual forage legume, but data were lacking for the effects of waterlogging on nodulated plants reliant on N2 fixation. Konnerup et al. find that plants...

Thermal acclimation of photosynthesis and dark respiration in white spruce
The results showed moderate thermal acclimation of respiration and no evidence for thermal acclimation of photosynthesis or local genetic adaptation for traits related to thermal acclimation.
Carnivory, more than meets the eye…
No morsel of the victim is wasted when a plant traps its prey.

Seedling photosynthesis and leaf respiration under climate change
Climate change is expected to bring warmer temperatures and more variable precipitation patterns worldwide, patterns that will depend on the ability of the world’s flora to take up carbon under these new conditions. In...

Photosynthetic responses to temperature in black spruce
The carbon balance of boreal terrestrial ecosystems is sensitive to increasing temperature, but the direction and thresholds of responses are uncertain. Jensen et al. measure seasonal- and cohort-specific photosynthetic...
Role of AOX1A in optimizing photosynthesis
Vishwakarma et al. treat wild-type and aox1a knock-out mutants of Arabidopsis thaliana with antimycin A and find that restriction of the cytochrome c oxidase (COX) pathway in the background of an impaired AOX pathway...
Hydathode trichomes in parasitic Orobanchaceae
This study provides the first evidence for the physiological role of the hydathode trichomes in active water secretion in the rhinanthoid Orobanchaceae.
Adaptation of cotton bracts to high CO2
They conclude that cotton bracts provide readily available material for studying adaptations to elevated CO2.
Modelling crown and wood characteristics of Pinus
Functional–structural tree models can be used not only for biomass and crown architecture modelling, but also for wood properties. Using L-system language, Fernández et al. develop a model based on plant allometry and...
