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.

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

Continual improvement to agricultural plant production is key to maintaining future sustainable growth in Australian agriculture. Our respective research teams are focussed on improving how plants utilise both nitrogen and water. Many questions remain with respect to where, how and when plants use and or access these important nutrients. The proposed facility will enable plant scientists to begin in-depth analysis of both nitrogen transport mechanisms and the ability to model root development and water allocation in crop species. This research will ultimately lead to improved knowledge on how plants respond to their environment and where modifications can be made to generate sustainable crops suited to Australian agriculture.Read moreRead less

The Australian Agrifood sector will benefit significantly from the establishment of functional genomics platform technologies, such as metabolomics, that underpin 'Systems Biology'; a new branch of biology that attempts to discover and understand biological properties that emerge from the interactions of many system elements. Australian agriculture will benefit through the development of techniques to improve both yield and quality through minimising the effects of abiotic and biotic stresses, and a reduced dependence on inputs (eg fertilisers) leading to environmentally sustainable production systems. Ultimately this will result in enhanced food quality and analytical methods to monitor quality and safety characteristics of food.Read moreRead less

This will be achieved through the application of bioinformatics for gene discovery and molecular, biochemical and genetics approaches to define gene function. Understanding mechanisms that control plant growth and development will ultimately impact on industries (agriculture, horticulture and forestry) vital to Australia's prosperity.Read moreRead less

Agro-ecosystem sensor capability for elevated carbon dioxide-free air research facility: This project will provide infrastructure upgrades to the Australian Grains Free Air Carbon dioxide Enrichment (AGFACE) facility, globally the only FACE facility in low rainfall, non-irrigated agri-ecosystems. Low rainfall, non-irrigated agriculture systems play a very significant role in global crop production and are predicted to be negatively affected by climate changes. The requested infrastructure will enable direct, plot scale measurements of crop water balance and water status, including crucial influence factors such as root growth and architecture and crop canopy temperatures, and allow manipulation experiments to develop adaptation options to improve crop resource use efficiencies.

Symbiotic transport proteins in legumes. Some plants form a symbiosis with soil bacteria (rhizobia) that convert atmospheric nitrogen to ammonia which is then supplied to the plant. This enables legumes to grow without application of nitrogen-based fertilizer, avoiding environmental problems such as run-off and land degradation, thereby contributing to sustainable agriculture practise. We will investigate the interactions between plant and rhizobia, focusing on identifying genes and proteins wh ....Symbiotic transport proteins in legumes.

This enables legumes to grow without application of nitrogen-based fertilizer, avoiding environmental problems such as run-off and land degradation, thereby contributing to sustainable agriculture practise. We will investigate the interactions between plant and rhizobia, focusing on identifying genes and proteins which govern nutrient exchange between the partners and development of the special structures in the roots that house the bacteria. Subsequent manipulation of these genes and proteins may allow us to identify control points and enhance nitrogen fixation.

This research hub aims to provide Australian growers and industrial stakeholders with improved plant materials to maximise production, environmental sustainability and profitability. In particular, the research aims to improve the nitrogen delivery capacity of legumes and their resilience to abiotic stress, which will be an important consideration as our climate changes. Grain legumes are often grown in rotation with cereal crops for their high nutritional seed value and their unique ability to develop a self-sufficient nitrogen-fixing symbiosis with soil bacteria. Maintaining legume productivity against the challenges of climate change and the need for increased food production is important to the future of Australian agriculture.Read moreRead less
