About the Project
Meiotic recombination generates the genetic diversity on which both evolution and crop breeding depend. In wheat and other cereals, crossovers are strongly biased towards certain regions of the genome, leaving vast stretches almost untouched. This is a major bottleneck for breeders racing to develop climate-resilient varieties, as beneficial alleles within these low-recombination regions cannot easily be separated from linked deleterious variants ("linkage drag").
This PhD will investigate whether the crossover landscape in wheat can be deliberately manipulated or exploited, combining fundamental meiotic cell biology with applied wheat genetics to generate tools relevant to future-proofing food security. First, you will use TILLING mutant alleles of meiotic genes, together with super-resolution microscopy and genomics, testing whether disrupting specific meiotic mechanisms can redistribute crossovers towards otherwise recombination-poor regions of the wheat genome. Second, you will investigate whether natural allelic variation in meiotic genes achieves the same effect, mining the rich genetic diversity of the JIC Watkins wheat landrace collection. Third, you will develop a high-throughput pollen-typing assay to measure recombination frequency directly in wheat gametes, and use this to run a genome-wide association study across the Watkins panel, hunting for novel loci that could unlock recombination exactly where breeders need it most.
You will be based in the Morgan group, and co-supervised by Dr Simon Griffiths, an expert in wheat quantitative genetics at the John Innes Centre, gaining training across meiotic cytology, molecular genetics, population genomics and quantitative statistical methods. This is a genuinely interdisciplinary project well suited to a student with a background in genetics, plant sciences, or a related bioscience discipline who is excited by fundamental cell biology with a clear route to real-world impact: the alleles and tools this project generates could help breeders develop climate-resilient wheat varieties faster than ever before.
The Norwich Research Park Biosciences Doctoral Training Programme (NRPDTP) is offering fully funded studentships for October 2027 entry. The programme offers postgraduates the opportunity to undertake a 4-year PhD research project whilst enhancing professional development and research skills through a comprehensive training programme. You will join a vibrant community of world-leading researchers. All NRPDTP students undertake a three-month professional internship placement (PIPS) during their study. The placement offers exciting and invaluable work experience designed to enhance professional development. Full support and advice will be provided by our Professional Internship team.
This project has been shortlisted for funding by the NRPDTP. Shortlisted applicants will be interviewed on the 2nd, 3rd and 4th February 2027.

Our partners value diverse and inclusive work environments that are positive and supportive. Students are selected for admission without regard to gender, marital or civil partnership status, disability, race, nationality, ethnic origin, religion or belief, sexual orientation, age or social background.
To maximise accessibility and attract students from underrepresented groups to our programme we have introduced bespoke templates for applicant Personal and Research statements which will enable every applicant to fully represent themselves through providing suitable examples and evidence. These forms are on the NRPDTP website and must be used for these sections of the application form.
