Marie is doing her PhD on biotransformation in microorganisms. She is investigating how the chemical composition of an environment influences the interactions and diversity of its microbiome. 1 year of this project will be with INTERACT, where she will focus on root exudate biotransformation in the wheat rhizosphere, by labelling plants with 13C and then combining chemical and biological analyses to follow the labelled compounds from soil excretion as root exudate, to various endpoints as it incorporates into microorganisms and is transformed into metabolites. This will identify any key species associated with wheat growth, and will reveal changes in rhizosphere microbiome and chemical composition, in response to stressors.
