Nucleolus targeting by negative strand RNA viruses. Negative strand viruses (NSVs) include diverse animal pathogens that represent significant threats to Australian livestock industries and access to export markets. The project aims to investigate the interface formed by NSVs with cellular nucleoli in order to determine roles in viral manipulation of cell biology during infection. This project hopes to address a major gap in knowledge in virology regarding the fundamental biology of NSVs, and is ....Nucleolus targeting by negative strand RNA viruses. Negative strand viruses (NSVs) include diverse animal pathogens that represent significant threats to Australian livestock industries and access to export markets. The project aims to investigate the interface formed by NSVs with cellular nucleoli in order to determine roles in viral manipulation of cell biology during infection. This project hopes to address a major gap in knowledge in virology regarding the fundamental biology of NSVs, and is expected to redefine our understanding of the virus-host interactions formed by these important pathogens. By determining the mechanisms of NSV-nucleolus interaction, the project plans to also provide important information for the development of new vaccines/therapeutics for livestock to combat NSVs that target nucleoli.Read moreRead less
A novel approach to fighting fungal infections: targeted disruption of hydrophobin monolayers. Fungal infestations of important crops such as cotton cause large economic losses to Australian agriculture while in the medical sector, fungal infections are responsible for high levels of mortality in immunocompromised patients. Our research will provide a new approach to fighting fungal infections by targeting the hydrophobin proteins, which form a robust coating on fungal aerial structures, such as ....A novel approach to fighting fungal infections: targeted disruption of hydrophobin monolayers. Fungal infestations of important crops such as cotton cause large economic losses to Australian agriculture while in the medical sector, fungal infections are responsible for high levels of mortality in immunocompromised patients. Our research will provide a new approach to fighting fungal infections by targeting the hydrophobin proteins, which form a robust coating on fungal aerial structures, such as spores. This layer is critical for fungal growth and reproduction and confers water resistance and tolerance to harsh conditions. Our work seeks to develop reagents that can specifically block regions on the protein that are responsible for forming this coating.

Cell wall structure and dynamics in emerging fungal pathogens of crops. The project aims to understand the role of fungal cell wall biosynthetic enzymes in cell wall stability. The fungal cell wall is a dynamic structure whose composition constantly changes in response to biotic and abiotic stresses and at different developmental stages. The devastating fungal crop pathogen Fusarium graminearum is responsible for the head blight disease in cereals. The project aims to understand the molecular ev ....Cell wall structure and dynamics in emerging fungal pathogens of crops. The project aims to understand the role of fungal cell wall biosynthetic enzymes in cell wall stability. The fungal cell wall is a dynamic structure whose composition constantly changes in response to biotic and abiotic stresses and at different developmental stages. The devastating fungal crop pathogen Fusarium graminearum is responsible for the head blight disease in cereals. The project aims to understand the molecular events that govern metabolism and dynamics of the cell wall of F. graminearum. The project also plans to characterise the molecular interactions involved in plant defence against fungal pathogens and fungal responses to plant immune factors called defensins. Expected long-term outcomes include the development of novel strategies for disease control and crop protection.Read moreRead less
Biogenesis of secretory organelles and the function of adhesins secreted during the establishment of plant disease. Many agriculturally important crops and Australian native plants are susceptible to diseases caused by species of Phytophthora, a fungus-like organism that lives in the soil. Economic losses due to Phytophthora diseases are estimated to exceed $200 million per annum and the scale of environmental damage in natural ecosystems is huge. Currently, control of Phytophthora diseases la ....Biogenesis of secretory organelles and the function of adhesins secreted during the establishment of plant disease. Many agriculturally important crops and Australian native plants are susceptible to diseases caused by species of Phytophthora, a fungus-like organism that lives in the soil. Economic losses due to Phytophthora diseases are estimated to exceed $200 million per annum and the scale of environmental damage in natural ecosystems is huge. Currently, control of Phytophthora diseases largely depends on a very small number of effective chemicals and there is an imminent risk of the development of pathogen resistance. This research will increase our understanding of how Phytophthora spores infect host plants and will identify suitable targets for the development of novel, environmentally safe chemicals that inhibit disease development.Read moreRead less
The molecular mechanism of bacterial ABC toxins. This project aims to establish that the ABC family of bacterial protein toxins, the main virulence factors in many species of naturally-occurring bacterial pathogens of insect pests, represent a protein machinery that cells and other organisms may use to deliver bioactive proteins to specific cells.

This project aims to establish that the ABC family of bacterial protein toxins, the main virulence factors in many species of naturally-occurring bacterial pathogens of insect pests, represent a protein machinery that cells and other organisms may use to deliver bioactive proteins to specific cells. ABC toxins are the main virulence factors in many species of naturally-occurring bacterial pathogens of insect pests. This project aims to establish that ABC toxins represent a new protein machinery that may be used more widely throughout cells and other organisms to direct the intercellular delivery of bioactive proteins in a highly cell-specific manner. The project expects these findings to enable the development of biopesticides based on ABC toxins, and generic intercellular protein delivery devices for biotechnological use.Read moreRead less
