To overcome the devastating economic and environmental impact of yellow rust, breeders and scientists have developed wheat varieties resistant to the disease. However, a general lack of understanding about how the yellow rust pathogen overcomes the plants resistance means that new varieties have not stayed resistant for long. This five-year project aims to tackle this.
Using new DNA sequencing technologies and a variety of strains of wheat yellow rust from Africa, India and the UK,we will sequence current and historical collections of yellow rust to understand how the disease has evolved over time and across continents. We hope that this new information at the DNA level will help maximize the potential for sustainable and durable resistance to the wheat yellow rust pathogen. Identifying those wheat genes best able to resist the pathogen for longer should enable new varieties of yellow rust resistant wheat to be bred, grown and harvested.
