The primary objective of my research is to gain a comprehensive mechanistic understanding of rhizosphere trait functionality for improved water use under drought in wheat (Triticum aestivum L.) and maize (Zea mays L.). Relevant traits include root structure related traits (e.g. root architecture and root hairs), root physiology related traits (e.g. exudation and mucilage production), and rhizosphere microbiome related traits (e.g. mycorrhization and microbiome selection).

A comparative approach is chosen to elucidate trait functions by focussing on a well-tailored selection of high yield varieties vs. old landraces and different soil textures. Process knowledge will be gained by measurements of the relation between soil- and leaf water potential and transpiration rates as well as stomata conductance. This will be linked to plant performance measured in phenotyping platforms, field trials as well as laboratory studies.
