Project description
Primary supervisor - Dr Chris Morgan
It has long been recognised that temperature affects meiotic crossover rates in a variety of species and that extreme high temperature can disrupt meiosis, leading to reduced fertility and yield in many crops. However, a detailed mechanistic understanding of why temperature affects meiotic recombination is currently lacking. We recently proposed a new model to explain how meiotic crossover rate and position is determined, based on the coarsening behaviour of a conserved protein, HEI10. Since HEI10 coarsening is envisioned as a physical process it is likely to be affected by temperature, and this in turn could help explain the mystery of why temperature affects crossover patterning. During this project,the student will study the interplay between temperature and crossover patterning and discover whether temperature-induced changes in coarsening dynamics can explain the long-recognised effect of temperature on recombination rate and fertility.This project will improve our fundamental understanding of how and why meiotic recombination is so exquisitively sensitive to temperature stress and, importantly, could pave the way for developing technologies to stregthen the temperature tolerance of meiosis and to ameliorate the impact of climate change on global crop yields.
