Doctorat / PhD Type de contrat : Full Time,Part Time,Fixed-Term/Contract Date limite de candidature : 2026-12-16T00:00:00+00:00

Funding for: UK Students, EU Students, International Students Funding amount: Fully-funded ARIES studentship covering Home fees, maintenance stipend (£21,805 p.a. for 2026-27) and a research training and support grant (£2,500). Limited number of studentships available for international applicants, with the difference between ‘Home’ and ‘International’ fees being waived by the registering university. ARIES funding does not cover additional costs associated with relocation to, and living in, the UK. Hours: Full-Time or Part-Time Closes: 16 December 2026 Background Climate change is increasing environmental pressures across natural and agricultural systems, with rising salinity and drought threatening ecosystem function and crop productivity. Understanding how plants naturally adapt to these stresses is therefore a major scientific and agricultural challenge. Sea beet (Beta vulgaris subsp. maritima), the wild ancestor of sugar beet, occupies coastal habitats spanning strong gradients in salinity, soil moisture, and disturbance, providing an exceptional natural system for studying environmental adaptation. By investigating ecophysiological variation across wild populations, this project will identify adaptive traits that can be translated into future sugar beet breeding. Working with commercial breeders at Lion Seeds Ltd., the project offers a unique opportunity to bridge fundamental ecology with real-world crop improvement. The project The successful candidate will combine field ecology, plant ecophysiology, and quantitative genetics to investigate adaptation across UK sea beet populations. The project will involve in situ phenotyping of wild plants alongside environmental characterisation of their habitats, including soil salinity, moisture, carbon, and nitrogen. Physiological traits linked to photosynthesis, water-use efficiency, and ecological strategy will be related to environmental gradients and variation among maternal families. The candidate will also help develop and analyse a sea beet × sugar beet mapping population to identify genomic regions underpinning salinity resilience and assess their breeding potential. Research will be undertaken across the University of Essex, the Earlham Institute, and Lion Seeds Ltd., providing experience in academic research and commercial crop breeding. This interdisciplinary project provides training in field ecology, plant ecophysiology, quantitative genetics, physiological phenotyping, genetic mapping, and statistical analysis in R. Through collaboration with Lion Seeds Ltd., the candidate will gain first-hand experience of commercial breeding, germplasm development, breeding programme design, and translating discoveries from wild species into improved crop varieties, providing outstanding preparation for careers in academia, industry, or environmental research.
