PhD Studentship at the University of East Anglia: Balancing Wheat Rust Resilience and Soil Microbial Diversity

This PhD project investigates how disrupting wheat disease susceptibility genes changes root exudation and shapes the wheat rhizosphere microbiome. The work sits at the interface of plant pathology, microbiome science, metabolomics, and sustainable agriculture, with a particular focus on wheat rust resistance and the broader ecological consequences of engineering disease-resilient crops.

The project builds on prior discovery of four wheat S-genes—TaBCAT1, TaCSP41a, TaICL and TaASIL2—that, when disrupted, confer protection against wheat rust fungi. The research asks an important next question: how do these genetic changes alter plant metabolism, root exudates, and the communities of microbes that colonise the rhizosphere? Understanding this is crucial for deploying resistant wheat lines in ways that preserve beneficial microbial diversity and support sustainable crop production.

Methodologically, the project combines field and greenhouse experiments, metagenomics, environmental microbiology, GC/MS metabolomics, and spatial landscape modelling. The successful candidate will characterise how S-gene disruption influences root microbial communities, identify metabolites that drive microbiome assembly, and evaluate optimal deployment strategies for mutant lines at landscape scale.

The studentship is linked to the international, multidisciplinary Saunders and Malone Labs at the John Innes Centre, with additional training in landscape modelling from research leaders at Exeter University. The training environment is broad and interdisciplinary, offering experience in plant pathology, molecular biology, environmental microbiology, and computational/landscape approaches relevant to agricultural systems.

Funding is provided through ARIES subject to UKRI terms and conditions. Eligible candidates will receive a fully funded studentship including tuition fees, a maintenance stipend of £21,805 per annum for 2026/27, and a research training and support grant (RTSG). A limited number of places are available for international applicants, with the home/international fee difference waived by the registering university, though relocation costs, visa costs, and the UK health surcharge are not covered.

The application deadline is 16 December. Interested applicants should apply via the University of East Anglia postgraduate research application portal and ensure they meet UKRI/ARIES eligibility criteria before submitting.
