Molecular dissection of resistance to subterranean clover mottle virus using Medicago truncatula

Plant virus diseases cause economic losses in most crop plants. Grain and pasture legumes are an important component of Australian agricultural cropping sytems, and provide human food and animal feed: they also contribute to higher yields of crops like cereals when grown in rotation, by providing nitrogen and a disease break. In this project, the 'model' legume, Medicago truncatula ('Barrel Medic') will be used to identify a new virus resistance gene. The knowledge gained will be used to improve resistance to viruses in crop legumes, so reducing losses and aiding sustainability of production. This will support rural communities and the national economy.
