Three new methods indicate that rising carbon dioxide reduces seedling respiration
Can new careful methods help us understand how plant respiration will be affected by rising carbon dioxide concentrations?

Can new careful methods help us understand how plant respiration will be affected by rising carbon dioxide concentrations?
Will photosynthetic processes of trees be able to keep up with future changes in temperature and precipitation under climate change?
A switch from linear to cyclic electron transport provides the extra boost needed until energy can be taken up from the insect itself.
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.
No morsel of the victim is wasted when a plant traps its prey.
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 results in a substantial decrease in respiration, photosynthesis, chloroplastic heat dissipation, ascorbate level and antioxidant systems.
This study provides the first evidence for the physiological role of the hydathode trichomes in active water secretion in the rhinanthoid Orobanchaceae.
They conclude that cotton bracts provide readily available material for studying adaptations to elevated CO2.
