A new study provides insight into the physiological and genetic control of transpiration in faba bean and opportunities for marker-assisted selection to improve its performance in water-limited environments.
Limited supply of mineral nutrients such as potassium increases the root-to-shoot ratio. This also increases the ratio between water-absorbing and -losing plant surface. Water uptake per unit surface has to either...
Air [CO2] tends to increase due to climate changes, affecting plant growth. Field-grown Coffea arabica trees were grown under actual and elevated [CO2] for four years. Rakocevic et al. find that elevated [CO2]...
Seeking to uncover the responses of root hydraulics and water uptake to transpirational water loss, Meng et al. analyse three-week old rice plants, observing changes in root aquaporin expression and hydraulic...
This study provides the first evidence for the physiological role of the hydathode trichomes in active water secretion in the rhinanthoid Orobanchaceae.
Stomata formed at high relative humidity (RH) are less responsive to abscisic acid (ABA), an effect that varies widely between genotypes. Giday et al. study four rose cultivars (Rosa hybrida) grown at 60% and 90% RH and...
Non-flowering plants have rather complex reproductive life cycles compared to the more familiar pattern of fertilization and seed formation seen in Angiosperms.
