Mechanisms of antifungal resistance in blackleg disease of canola. This project aims to determine how fungicide resistance evolves in the fungus Leptosphaeria maculans, the major pathogen of the oilseed crop canola. Global food production has become more reliant on the use of antifungal agents to protect crops, however these advances are now threatened by the emergence of drug-resistant microbes. The knowledge generated by this project will be used to reduce the risk of resistance evolving in po ....Mechanisms of antifungal resistance in blackleg disease of canola. This project aims to determine how fungicide resistance evolves in the fungus Leptosphaeria maculans, the major pathogen of the oilseed crop canola. Global food production has become more reliant on the use of antifungal agents to protect crops, however these advances are now threatened by the emergence of drug-resistant microbes. The knowledge generated by this project will be used to reduce the risk of resistance evolving in populations of the blackleg fungus. This will have economic benefits through ensuring increased canola yields, while providing health and environmental benefits through minimisation of use of fungicides.Read moreRead less

Gene identification and genetic marker analysis of herbicide resistance in Lolium rigidum. Herbicide resistance threatens the vibrant, export-focused Australian cropping industry and environmental sustainability. The Australian herbicide resistance problem is far greater than elsewhere in the world. Herbicide resistance must be avoided, managed and reversed to ensure profitable agriculture and an environmentally sustainable landscape. This research will contribute to the national wealth through ....Gene identification and genetic marker analysis of herbicide resistance in Lolium rigidum. Herbicide resistance threatens the vibrant, export-focused Australian cropping industry and environmental sustainability. The Australian herbicide resistance problem is far greater than elsewhere in the world. Herbicide resistance must be avoided, managed and reversed to ensure profitable agriculture and an environmentally sustainable landscape. This research will contribute to the national wealth through helping ensure the profitability of vital Australian export agricultural industries and the sustainability of the soil/land resource. This proposal will ensure that Australia leads international herbicide resistance research and will enable the capture of intellectual property and commercial opportunities. Read moreRead less
Seed quality and disease resistance trait mapping in lentil (Lens culinaris ssp. culinaris). To protect and increase our world lentil market share, the mission of the Australian lentil breeders is to develop lentil varieties with superior seed qualities. Three highly desirable seed quality traits are; fatter and larger shape, better splitting efficiency and resistance to blemishing by ascochyta blight infection. To speed up the development of varieties with these traits, the genetic loci governi ....Seed quality and disease resistance trait mapping in lentil (Lens culinaris ssp. culinaris). To protect and increase our world lentil market share, the mission of the Australian lentil breeders is to develop lentil varieties with superior seed qualities. Three highly desirable seed quality traits are; fatter and larger shape, better splitting efficiency and resistance to blemishing by ascochyta blight infection. To speed up the development of varieties with these traits, the genetic loci governing them will be characterised and closely associated molecular markers identified. Markers will be validated for their use in marker-assisted breeding programs via back-crossing and field and glass house testing.Read moreRead less
Pyramiding ascochyta blight (A. rabiei) resistance in chickpea. Ascochyta blight (A. rabiei) is the most devastating disease that affects chickpea production in Australia. This project will produce enhanced chickpea breeding germplasm with sustainable resistance to ascochyta blight. This will be achieved through the enrichment of highly informative genome linkage maps and the development of molecular markers closely associated with novel resistance genes. Markers will be used to screen backcross ....Pyramiding ascochyta blight (A. rabiei) resistance in chickpea. Ascochyta blight (A. rabiei) is the most devastating disease that affects chickpea production in Australia. This project will produce enhanced chickpea breeding germplasm with sustainable resistance to ascochyta blight. This will be achieved through the enrichment of highly informative genome linkage maps and the development of molecular markers closely associated with novel resistance genes. Markers will be used to screen backcrossed populations for novel resistance in order to pyramid the genes involved. The most resistant lines, to all of the A. rabiei pathotypes, will be selected for use in future resistance breeding programs.Read moreRead less
Extracellular vesicles in the pathogenesis of fungal plant disease. Extracellular vesicles (EVs) are small membrane bound sacs that carry information between cells in essentially all organisms. EVs are also produced by bacterial and fungal pathogens and have a crucial role in infection in mammals . We propose that fungal EVs are key players in the establishment of fungal diseases in plants. We have isolated EVs from the cereal pathogen Fusarium graminearum which decreases yield and quality of gr ....Extracellular vesicles in the pathogenesis of fungal plant disease. Extracellular vesicles (EVs) are small membrane bound sacs that carry information between cells in essentially all organisms. EVs are also produced by bacterial and fungal pathogens and have a crucial role in infection in mammals . We propose that fungal EVs are key players in the establishment of fungal diseases in plants. We have isolated EVs from the cereal pathogen Fusarium graminearum which decreases yield and quality of grain in major food crops such as wheat, barley and corn. This project will focus on the cargo that EVs transport through the fungal cell wall and into the plant host and will establish the role of this cargo in disease progression. Ultimately, this knowledge will be used to design new strategies for disease control.Read moreRead less
