This project aims to determine how plants can increase their water availability by altering the small volume of soil, rhizosheath that adheres to roots. This project expects to integrate root exudates metabolomics, biophysics and microbial ecology to determine for the first time which of a suite of interconnected factors increase water availability in the root zone. Expected outcomes include better understanding of the direct and indirect roles of soil pore geometry, root exudates and microbial communities play in shaping plant’s ability to take up water from soil. This knowledge may ultimately pave the way for engineering the rhizosheath of crops to cope with increased drought conditions.

这个项目旨在确定植物如何通过改变附着在根上的土壤和根鞘的小体积来增加它们的水分供应。
