Quantification and Modeling of Local Root Water Uptake Using Neutron Radiography and Deuterated Water
Knowledge of local water fluxes across the soil–root interface is essential to understand and model root water uptake. Despite its importance, there is a lack of direct methods to measure theExpand

Mucilage exudation facilitates root water uptake in dry soils.
As plant roots take up water and the soil dries, water depletion is expected to occur in the rhizosphere. However, recent experiments showed that the rhizosphere was wetter than the bulk soil duringExpand

Rhizosphere shape of lentil and maize : Spatial distribution of enzyme activities
Abstract The rhizosphere, the small soil volume that surrounds and is influenced by plant roots, is one of the most dynamic biological interfaces on Earth. Enzymes, produced by both roots andExpand

Root hairs enable high transpiration rates in drying soils.
Do root hairs help roots take up water from the soil? Despite the well-documented role of root hairs in phosphate uptake, their role in water extraction is controversial. We grew barley (HordeumExpand

Nonequilibrium water dynamics in the rhizosphere: How mucilage affects water flow in soils
The flow of water from soil to plant roots is controlled by the properties of the narrow region of soil close to the roots, the rhizosphere. In particular, the hydraulic properties of the rhizosphereExpand

Root hairs increase rhizosphere extension and carbon input to soil
Background and Aims Although it is commonly accepted that root exudation enhances plant-microbial interactions in the rhizosphere, experimental data on the spatial distribution of exudates areExpand

Biophysical rhizosphere processes affecting root water uptake.
BACKGROUND Recent advances in imaging techniques now make it possible to visualize the biogeochemical and physical environment around the roots, the rhizosphere. Detailed images of pore spaceExpand

Where do roots take up water? Neutron radiography of water flow into the roots of transpiring plants growing in soil.
Where and how fast does water flow from soil into roots? The answer to this question requires direct and in situ measurement of local flow of water into roots of transpiring plants growing in soil.Expand

Measurements of water uptake of maize roots: the key function of lateral roots
AimsMaize (Zea mays L.) is one of the most important crops worldwide. Despite several studies on maize roots, there is limited information on the function of different root types in extracting waterExpand
