Crop Genetics

Weather and climate have important influences on plant development which ultimately cause variation in crop yield and crop performance known as yield instability.

Breeding more resilient crops will be important for mitigating the effects of changes in weather and climate on crop performance, but to do this we need a good understanding of the biological processes that underlie variation in yield.  

A key feature of most plants is that seed development and seed performance are highly dependent on the environment which the parent plants have experienced.

Steve's group are focussed on understanding how temperature variation during seed production leads to changes in seeds, including seed development, seed dormancy and post-germination growth vigour. Because most major crops are seed crops, they are showing that these processes lead to yield variation in major crops, at the laboratory, field and landscape scales.

Using this knowledge we are devising and testing strategies to engineer rapeseed and vegetable Brassica crops to be less sensitive to the environment, and to perform more resiliently for farmers and growers even in the face of weather variation and climate change.

Working with industrial partners they're taking novel germplasm through to field trials to evaluate potential for genetic seed quality improvement.
