The Penfield group works to understand how weather and climate affect plant reproductive development and seed quality.
They are especially interested in the effects of temperature on crop yields, seed quality and seedling establishment.
Their work uses crop species from the Brassica family, especially oilseed rape (canola) and vegetable Brassicas, as well as model species such as Arabidopsis thaliana.
In this way they aim to understand precise mechanisms by which weather and climate affect crop performance, an consider strategies for increasing crop resilience, for instance using conventional plant breeding or genome editing techniques.

Opportunities
We’re looking for a Postdoctoral Researcher to join the lab to oversee a programme of marker discovery and population development aimed at designing more resilient high yielding varieties of oilseed rape.
We’re also looking for a Research Assistant to investigate how the mother plant controls the germination of her progeny seeds, and testing the effects of different gene variants on germination control
Both positions close on Wednesday 29 January
