Co-evolution of the host pathogen interaction between Leptosphaeria maculans and Brassica species. Brassica canola is Australia's third largest export crop, producing 13% of the world's canola oil. However, blackleg disease, caused by the fungus Leptospheria maculans leads to annual yield losses of 15%, with 100% loss associated with breakdown of resistance. International investment has provided novel genome resources for Brassica and L. maculans. Applying these resources to understand the co-ev ....Co-evolution of the host pathogen interaction between Leptosphaeria maculans and Brassica species. Brassica canola is Australia's third largest export crop, producing 13% of the world's canola oil. However, blackleg disease, caused by the fungus Leptospheria maculans leads to annual yield losses of 15%, with 100% loss associated with breakdown of resistance. International investment has provided novel genome resources for Brassica and L. maculans. Applying these resources to understand the co-evolution of this plant-fungal interaction could prevent the current boom-bust cycle of canola production in Australia. This study will also provide a model and knowledge base for applications in other species, leading to enhanced crops with increased plant protection and robust, reliable productivity.Read moreRead less
Role of alanine aminotransferase in improved nitrogen use efficiency (NUE) in cereals. The use of nitrogen-based fertilisers by crop plants is poor where efficiencies (nitrogen taken up to that applied) is often less than 40%. Nitrogen not used is often lost to the environment through leaching and or volatilisation. Improving nitrogen use efficiency (NUE) in agriculture will decrease overall nitrogen fertiliser use and minimise its environmental footprint. This project will characterise a nov ....Role of alanine aminotransferase in improved nitrogen use efficiency (NUE) in cereals. The use of nitrogen-based fertilisers by crop plants is poor where efficiencies (nitrogen taken up to that applied) is often less than 40%. Nitrogen not used is often lost to the environment through leaching and or volatilisation. Improving nitrogen use efficiency (NUE) in agriculture will decrease overall nitrogen fertiliser use and minimise its environmental footprint. This project will characterise a novel NUE technology that when transferred to plants significantly improves NUE. We will define the phenotype at the molecular, biochemical and physiological levels to maximise its adoption to other agricultural crops such as wheat, barley and maize.Read moreRead less
