Abstract excerpt

Understanding the coordination between root and shoot hydraulics is fundamental for improving plant performance under water stress. We used the Arabidopsis thaliana double mutant epf1 epf2, which displays elevated stomatal density and transpiration rate, to investigate how root hydraulics is influenced by enhanced transpiration. Mutant and wild-type (Col-0) plants were grown hydroponically under control and...
