Functional characterisation of the necrotrophic effector proteins Tox1 and Tox3 from the wheat pathogen Stagonospora nodorum. Fungal pathogens cost the Australian agricultural industry over one billion dollars per year. This project will build upon recent key advances to provide a fundamental basis on how fungal pathogens cause disease. The results from this study will promote future advances in disease management with the aim of securing Australian wheat supplies.
Interactions between genotype, plant nutrition and fungal disease development in strawberry. Strawberry (Fragaria x ananassa) growers lose more than 30% of their crop annually to disease. This project will elucidate the role of plant nutrition in disease development and investigate the interaction/s between plant genotype, pathogen and the environment. The physiological basis for durable resistance will also be established. Molecular markers for field resistance and nutrient use efficiency will ....Interactions between genotype, plant nutrition and fungal disease development in strawberry.

This project will elucidate the role of plant nutrition in disease development and investigate the interaction/s between plant genotype, pathogen and the environment. The physiological basis for durable resistance will also be established. Molecular markers for field resistance and nutrient use efficiency will be developed for use in breeding programs. Furthermore, this project will enhance profitability and sustainability of the Australian strawberry industry.

Understanding the evolution of fungicide resistance for durable control of fungal pathogens in pyrethrum. The pyrethrum plant is grown for the extraction of natural insecticidal pyrethrins used in a variety of pest control products. Australia supplies 60 per cent of the global market for natural pyrethrins. Fungal pathogens of pyrethrum can cause severe losses. This project will investigate fungicide resistance in these pathogens at the molecular level.
Regulation and expression of disease resistance responses in the Rhynchosporium secalis/barley interaction. The barley leaf scald fungus, Rhynchosporium secalis, causes annual losses of up to 10% in Australia's major export crop, barley. The primary aim of this project is to isolate and understand the interplay of genes specifically involved in the regulation of resistance to scald. Several resistance-specific genes will be functionally analysed to identify regulatory signalling pathways that li ....Regulation and expression of disease resistance responses in the Rhynchosporium secalis/barley interaction. The barley leaf scald fungus, Rhynchosporium secalis, causes annual losses of up to 10% in Australia's major export crop, barley. The primary aim of this project is to isolate and understand the interplay of genes specifically involved in the regulation of resistance to scald. Several resistance-specific genes will be functionally analysed to identify regulatory signalling pathways that link genetic expression with the specific gene-for-gene disease resistance phenotype. Knowledge of the genes controlling signalling processes within the disease-challenged plant will allow for the development of more effective and durable resistances by traditional breeding and transgenic approaches.Read moreRead less
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

Phytosphere: new facilities for controlled manipulation of effects of climate change & airborne pollutants on disease epidemiology & plant performance. Western Australia is home to a range of world-leading plant science research groups. Establishing a world-class multi-purpose phytosphere facility in WA will enable these groups to remain at the forefront of their research fields and continue to attract high-profile international scientists and students. Such a facility will result in significant ....Phytosphere: new facilities for controlled manipulation of effects of climate change & airborne pollutants on disease epidemiology & plant performance. Western Australia is home to a range of world-leading plant science research groups. Establishing a world-class multi-purpose phytosphere facility in WA will enable these groups to remain at the forefront of their research fields and continue to attract high-profile international scientists and students. Such a facility will result in significant advancement of our understanding of the impact of climate change on plants through biotic stresses (e.g., disease epidemiology, plant-pathogen interactions) and in interaction with abiotic variables (e.g., CO2 concentrations, temperature, light intensity, humidity, moisture stress, airborne pollutants such as SO2), and allow crop yield optimisation in future environments.Read moreRead less
Isolation and functional characterisation of a pathogen meta effector able to inhibit detection of multiple disease effectors by resistant plants. The rust fungi are a major economic threat to crop production in Australia. This project will investigate the molecular mechanism used by a rust fungus to prevent detection of multiple disease-inducing proteins by resistant plants and generate knowledge that will lead to the development of new and more effective disease control strategies.
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.
Plant microRNA systems: investigating slicing versus translational repression and the development of an anti-viral defence mechanism. The ability to specifically switch off genes has revolutionised biotechnological approaches, from fighting diseases to developing superior crops, however the underlying mechanism is poorly understood, limiting its application in practice. Outcomes from this project will provide such knowledge, allowing its precise use in diverse applications.
The identification of Mycosphaerella graminicola effectors that promote pathogenicity on wheat. Fungal diseases are one of the greatest challenges to sustainable wheat production in the 21st century. Septoria tritici blotch is one such disease as it inflicts millions of tonnes in yield losses per annum. This project will identify the molecular basis of Septoria tritici blotch and assess its potential as an Australian biosecurity threat.
