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
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.

My enemy’s enemy is my friend: The genetics of major plant pathogen killers. Fungi are devastating agents of crop diseases. These plant pathogens, in turn, are often parasitized by other fungi in the field. The project will focus on such interactions between powdery mildews, important pathogens of many crops and wild plants, and their common fungal parasites (Ampelomyces spp.) that have already been utilised as
biocontrol agents in crop protection. Genetic and genomic tools will be used to deter ....My enemy’s enemy is my friend: The genetics of major plant pathogen killers. Fungi are devastating agents of crop diseases. These plant pathogens, in turn, are often parasitized by other fungi in the field. The project will focus on such interactions between powdery mildews, important pathogens of many crops and wild plants, and their common fungal parasites (Ampelomyces spp.) that have already been utilised as
biocontrol agents in crop protection. Genetic and genomic tools will be used to determine if these parasites evolved by switching host from plants to plant pathogens. The project has the potential to make a ground-breaking discovery in this field, and also establish the starting point for new innovative methods to protect a wide diversity
of crops using these fungi or specific compounds derived from them.Read moreRead less
Mediator: a new concept for controlled gene expression in plant biotechnology. The Mediator protein complex is a new control point for the activation of all genes in higher organisms and the purpose of this project is to understand how three Mediator subunits regulate disease resistance in plants. The outcomes provide a new concept to direct natural gene expression towards robust crop plants able to cope with climatic variations.
The roles viruses play in the decline of terrestrial orchids in Australia’s hotspot of global biodiversity. Plant viruses play both positive and negative roles in native plant health and population viability. This study will use deep sequencing and plant physiology approaches to elucidate how threatened terrestrial orchids respond to infection by exotic and indigenous viruses, allowing more informed management of critically-important ecosystems.
