In touch with the environment: dissecting early tactile responses in plants. This project aims to identify the regulatory mechanisms that control touch-responses in plants. Although plants cannot relocate in the face of danger, they are able to sense mechanical manipulations from the environment. These could be caused by pathogens, herbivores, rain or even wind. This touch-responsiveness of plants is essential for pathogen resistance and for triggering architectural changes to overcome obstacles ....In touch with the environment: dissecting early tactile responses in plants. This project aims to identify the regulatory mechanisms that control touch-responses in plants. Although plants cannot relocate in the face of danger, they are able to sense mechanical manipulations from the environment. These could be caused by pathogens, herbivores, rain or even wind. This touch-responsiveness of plants is essential for pathogen resistance and for triggering architectural changes to overcome obstacles and prevent mechanical damage. Using a comprehensive tool set of genetics, genomics and proteomics, this project aims to identify the upstream regulators that control touch responses. Furthermore, it is expected to expand our understanding of the physiological impacts of touch-responses on growth and stress tolerance.Read moreRead less
Biosynthesis and functions of two phytotoxins in Septoria nodorum blotch. This project aims to investigate how a fungal plant pathogen makes and uses small bioactive molecules to facilitate infection. It will characterise the function of the genes and enzymes involved in the biosynthesis of a light-activated phytotoxic molecule and a potential anti-plant defence molecule found in the pathogenic wheat fungus Parastagonospora nodorum, and investigate their contribution to disease development.

This project aims to investigate how a fungal plant pathogen makes and uses small bioactive molecules to facilitate infection. It will characterise the function of the genes and enzymes involved in the biosynthesis of a light-activated phytotoxic molecule and a potential anti-plant defence molecule found in the pathogenic wheat fungus Parastagonospora nodorum, and investigate their contribution to disease development. Expected outcomes include better understanding of plant-microbe interactions, disease management strategies, technologies for identifying biosynthetic pathways in other fungi, and enzyme technology for synthesising molecules. This could lead to new herbicides, biopesticides and drugs.Read moreRead less

Molecular interaction between tomato and Fusarium oxysporum. This project aims to develop fungus-resistant crops. Fungal pathogens of crop plants threaten food production food security. The fungus Fusarium oxysporum is the fifth most notorious fungal pathogens of crop plants. This project will use the tomato–Fusarium oxysporum pathosystem to discover how Fusarium manipulates plants to infect them and how plants can resist Fusarium infection. Anticipated outcomes include reduced yield loss in tom ....Molecular interaction between tomato and Fusarium oxysporum. This project aims to develop fungus-resistant crops.

This project will use the tomato–Fusarium oxysporum pathosystem to discover how Fusarium manipulates plants to infect them and how plants can resist Fusarium infection. Anticipated outcomes include reduced yield loss in tomato and other crop plants by using genome-editing techniques to develop Fusarium-resistant cultivars.Read moreRead less
The roles of pathogen effectors in promoting rust diseases of plants. Rust diseases threaten global food security. This cross-institutional project aims to discover how proteins secreted by rust fungi promote disease following their translocation into plant cells. It will use the interaction between flax and the flax rust fungus as a powerful model system to test the hypothesis that manipulation of host RNA metabolism is a fundamental mechanism underpinning rust pathogenesis. This research is in ....The roles of pathogen effectors in promoting rust diseases of plants. Rust diseases threaten global food security. This cross-institutional project aims to discover how proteins secreted by rust fungi promote disease following their translocation into plant cells. It will use the interaction between flax and the flax rust fungus as a powerful model system to test the hypothesis that manipulation of host RNA metabolism is a fundamental mechanism underpinning rust pathogenesis. This research is intended to dramatically improve our understanding of the molecular mechanisms used by rust fungi to establish infection. The knowledge gained is expected to facilitate the development of new strategies for rust disease management in food crops by identifying pathogenic processes that can be targeted for intervention.Read moreRead less
Molecular basis for susceptibility and immunity to Fusarium wilt disease. Fusarium wilt is a devastating disease of many important crop plants, including banana, cotton and tomato. There are significant gaps in our understanding of this disease that need to be addressed to enable better disease management. This project aims to identify and analyse tomato proteins targeted by Fusarium effector proteins (virulence factors), determine how corresponding tomato receptors (resistance proteins) recogni ....Molecular basis for susceptibility and immunity to Fusarium wilt disease. Fusarium wilt is a devastating disease of many important crop plants, including banana, cotton and tomato. There are significant gaps in our understanding of this disease that need to be addressed to enable better disease management. This project aims to identify and analyse tomato proteins targeted by Fusarium effector proteins (virulence factors), determine how corresponding tomato receptors (resistance proteins) recognise these effectors, and identify the signalling pathways and critical defence responses activated by these receptors. The intention is to close the gaps in our understanding and use the knowledge gained to develop new strategies for disease control by interfering with fungal pathogenicity and enhancing plant resistance.Read moreRead less
Transcriptome profiling of Phytophthora pathogenicity genes: regulation of cell wall degrading enzyme synthesis during plant infection. This project will catalogue the repertoire of enzymes produced by plant pathogens to break down plant cell walls during initial penetration and later establishment of disease. This project will determine how production of these enzymes is regulated and how their function is optimised to achieve successful plant infection.
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.
Molecular basis of rust infection and host plant resistance. Plant diseases threaten agricultural productivity in Australia, with rust fungi being a major problem for cereal grain production. This project will investigate molecular processes underlying the infection of plants by rust fungi and will provide basic knowledge for development of novel and durable disease resistance strategies.

Enhancing resistance to wheat stripe rust disease. This project aims to investigate why wheat succumbs to stripe rust fungus, a grave threat to global wheat production. Wheat is the primary agricultural and revenue crop of Australia, cultivated since early European settlement. Severe disease epidemics arise when the fast evolving rust pathogen breaks down host plant genetic resistance.

This project aims to investigate why wheat succumbs to stripe rust fungus, a grave threat to global wheat production. Wheat is the primary agricultural and revenue crop of Australia, cultivated since early European settlement. Severe disease epidemics arise when the fast evolving rust pathogen breaks down host plant genetic resistance. This project will investigate the molecular mechanisms of host-pathogen recognition and the consequences of pathogen variation to determine the causes of resistance breakdown. The expected outcome is robust rust-resistant wheat cultivars to maintain global food security.Read moreRead less
