Studying the influence of root hairs on the microstructure of rhizosphere soil and its implication for root water uptake
Roots interact in various ways with the surrounding soil to facilitate water and nutrient uptake. Thereby, they induce changes in the properties of rhizosphere soil. Besides root exudates, root hairs seem to play an important role in modifying the pore structure of the rhizosphere, which is thought to significantly contribute to its distinct hydraulic behaviour observed in various neutron experiments. To better understand the structural alterations of the rhizosphere soil induced by root hairs including its implications for the root water uptake, we propose a study on maize plants comparing a hairless mutant with a hairy wild type. We will apply a combination of high-resolution neutron (NT) and X-ray tomography (XCT) to visualize and quantify transport-relevant changes in the rhizosphere microstructure and relate this highly resolved soil water patterns around the root surface. We expect to gain new insights into the specific hydraulic behaviour of rhizosphere soil as well as into the mechanism triggering the formation of the rhizosheath.
