Pathogenicity genes of the blackleg fungal pathogen of canola. Blackleg disease, caused by the fungus, Leptosphaeria maculans, is the most serious disease of canola (Brassica napus) Australia and worldwide. Control strategies require knowledge of mechanisms of both plant defence (resistance) and fungal pathogenicity; little is known about such processes for blackleg. I will make pathogenicity mutants of L.maculans (unable to attack canola) and characterise the mutated genes. This project will ....Pathogenicity genes of the blackleg fungal pathogen of canola. Blackleg disease, caused by the fungus, Leptosphaeria maculans, is the most serious disease of canola (Brassica napus) Australia and worldwide. Control strategies require knowledge of mechanisms of both plant defence (resistance) and fungal pathogenicity; little is known about such processes for blackleg. I will make pathogenicity mutants of L.maculans (unable to attack canola) and characterise the mutated genes. This project will develop a better understanding of the disease process for blackleg, identify novel disease control targets in this important fungus and lead to disease resistant canola.Read moreRead less
Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts. This research will improve productivity of bluegum plantations by improving current diagnostic techniques (foliage and soil analysis) for nutrient disorders and the supply of water. Using a novel phloem sampling and analysis technique, we will develop a nutrient (e.g. N, P) and water diagnosis procedure that is quick, cheap, robust and reliable for field use. A major in ....Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts. This research will improve productivity of bluegum plantations by improving current diagnostic techniques (foliage and soil analysis) for nutrient disorders and the supply of water. Using a novel phloem sampling and analysis technique, we will develop a nutrient (e.g. N, P) and water diagnosis procedure that is quick, cheap, robust and reliable for field use. A major innovation will be distinguishing the effects of shortages of water on growth from those of other growth influences. Overall, this project will provide a highly significant theoretical, conceptual and practical advance in mid-rotation, diagnostics for plantations with considerable commercial promise.Read moreRead less
A novel link between plant pathogen defence and DNA repair capability. Plants and plant-based industries are essential for the provision of food, clothing and building materials and underpin the economies of rural communities. Plant yield and quality and the biodiversity of natural systems are dramatically reduced by disease. The fundamental knowledge gained from our research will enable manipulation of the factors that enhance disease resistance resulting in a significant benefit to Australian ....A novel link between plant pathogen defence and DNA repair capability. Plants and plant-based industries are essential for the provision of food, clothing and building materials and underpin the economies of rural communities. Plant yield and quality and the biodiversity of natural systems are dramatically reduced by disease. The fundamental knowledge gained from our research will enable manipulation of the factors that enhance disease resistance resulting in a significant benefit to Australian agriculture and protection of our natural resources. The current reliance for disease control on chemicals that damage the environment will be reduced and our research will contribute directly to the provision of cheaper, simpler and more effective methods of control.

PHYSIOLOGICAL AND BIOCHEMICAL DISSECTION OF COBALT ACCUMULATION BY PLANTS. Co is a valuable metal for the Australian economy. The project will advance phytomining of non-economic Co ores and also the phytoremediation of (60)Co-contaminated soils. It will assist development of phytotechnologies for Co, eg improvement of Co content of fodder crops for ruminants in Co-deficient areas. All these applications will benefit ARC's National Research Priorities Goal 1: an environmentally friendly Australi ....PHYSIOLOGICAL AND BIOCHEMICAL DISSECTION OF COBALT ACCUMULATION BY PLANTS. Co is a valuable metal for the Australian economy. The project will advance phytomining of non-economic Co ores and also the phytoremediation of (60)Co-contaminated soils. It will assist development of phytotechnologies for Co, eg improvement of Co content of fodder crops for ruminants in Co-deficient areas. All these applications will benefit ARC's National Research Priorities Goal 1: an environmentally friendly Australia. Understanding Co uptake by accumulator species will also promote awareness, conservation and sustainable use of biodiversity in Australia. Outcomes will impact on Goal 3: frontier technologies, as the potential spin-off applications of Co-based phytotechnologies will fuel future environmental technologies in Australia.Read moreRead less

Summary
Towards understanding the molecular details of canola-infection by Fusarium. This project aims at improving our understanding of how canola plants are infected by the pathogenic fungus Fusarium oxysporum. Canola is the primary oilseed crop, and the overall third most important crop in Australia, accounting for a 3 billion AUS$ industry. Fusarium is a relatively new fungal disease to Australian canola, but projected to become a serious threat in the future. The project will provide insights into ....Towards understanding the molecular details of canola-infection by Fusarium. This project aims at improving our understanding of how canola plants are infected by the pathogenic fungus Fusarium oxysporum. Canola is the primary oilseed crop, and the overall third most important crop in Australia, accounting for a 3 billion AUS$ industry. Fusarium is a relatively new fungal disease to Australian canola, but projected to become a serious threat in the future. The project will provide insights into the earliest stages of plant-infection by the fungus on a cellular level, using molecular biology, genetics and microscopic tools. Expected outcomes of this research include the identification of key components to improve plant defense against Fusarium, and the development of strategies to improve the plant's resilience.Read moreRead less
