Mucilage facilitates root water uptake under edaphic stress: first evidence at the plant scale.

Abstract excerpt

BACKGROUND AND AIMS: Mucilage has been hypothesized to soften the gradients in matric potential at the root-soil interface, thereby facilitating root water uptake in dry soils and maintaining transpiration with a moderate decline in leaf water potential. So far, this hypothesis has been tested only through simplified experiments and numerical simulations. However, the impact of mucilage on the relationship...
