Wheat sustainability

Wheat is one of the most important crops in the world, but as the population grows and the climate changes, we will need to develop more resilient, nutrient and water-efficient varieties. We are investigating the basis for variation in some of these traits in diverse landrace wheats.


Ralstonia bacterial wilt

Ralstonia solanacearum is a bacterial pathogen of global importance, causing diseases such as bacterial wilt and potato brown rot. This collaborative project is investigating sustainable ways to control this pathogen, such as treatment with phages or breeding genetic resistance into crops.
