Agriculture is an important economic activity in Australia that results in considerable export revenues. Two of the major problems facing agriculture around the globe are the incidence of diseases and the scarcity of water. Agricultural losses caused by plant pathogens and low water availability account for billions of dollars every year and have profound economic and social implications. Water is an extremely scarce resource in Australia and periodic droughts inflict immense losses to the Australian agricultural sector. Our research will explore new and cleaner strategies to provide crop protection as well as to increase water use efficiency.Read moreRead less

Its importance is highlighted by the wide use of agricultural nitrogen fertilizers in Australia and world wide. This comes at substantial costs for the environment and the economy, due to low nitrogen use efficiency of cereals and environmental impacts. By understanding plant responses to nitrogen we can improve nitrogen efficiency. This project will identify proteins and peptides as biomarkers of plant responses to nitrogen withdrawal. Such biomarkers can be used in plant breeding and in agricultural prediction of plant nitrogen requirements with the potential to reduce agricultural costs and environmental impacts.Read moreRead less

The development of hard carbon anode materials for stationary rechargeable sodium and potassium ion batteries remains a major technological challenge. This project aims to utilise two very different biomass feedstock sources, sorghum and macadamia shell agricultural waste to manufacture low-cost, high-performance carbon anodes. Current carbon anode materials such as graphite or carbonised sucrose, pitch or phenolics suffer from poor performance, high cost and/or low carbon yield and device durability issues. This project will investigate combinations of biomass precursors, tailored graphene and carbon alloys in order to significantly enhance anode performance while minimising cost.Read moreRead less
The Betaproteobacteria: could they play a key role in nitrogen fixation on infertile soils with legumes adapted to climate change? Microbial biosecurity is often overlooked when introducing agricultural species to Australia. As we research new legume species to make our $44 billion agricultural industries robust in the face of a changing climate, we need to be aware of the implications of the associated introduction of (beneficial) microbes. By exploring the globe for plants from regions that al ....The Betaproteobacteria: could they play a key role in nitrogen fixation on infertile soils with legumes adapted to climate change? Microbial biosecurity is often overlooked when introducing agricultural species to Australia. As we research new legume species to make our $44 billion agricultural industries robust in the face of a changing climate, we need to be aware of the implications of the associated introduction of (beneficial) microbes. By exploring the globe for plants from regions that already have the climate we are transitioning towards, we have discovered new perennial forage legumes from which we can build a robust agriculture in the arid regions of southern Australia. This will have enormous national benefit in rural regions. This project will research the essential microbial inoculants associated with these new plants.Read moreRead less
Investigation of the impact of malt haze active proteins to improve brewing efficiency and beer quality. Australia is a major world exporter of malting barley (~2 millon t/pa) and malt (600,000 t/pa), primarily to the rapidly expanding Asian economic development region. An additional 200,000 t/pa of malt is provided to the Australian domestic brewing industry. By improving the quality of Australian malting barley and optimising the cost of brewery colloidal stabilisation measures, we expect hi ....Investigation of the impact of malt haze active proteins to improve brewing efficiency and beer quality. Australia is a major world exporter of malting barley (~2 millon t/pa) and malt (600,000 t/pa), primarily to the rapidly expanding Asian economic development region. An additional 200,000 t/pa of malt is provided to the Australian domestic brewing industry. By improving the quality of Australian malting barley and optimising the cost of brewery colloidal stabilisation measures, we expect higher demand and prices for Australian malting barley and malt. This will help support the viability of rural communities and the value adding involved in the malting and brewing of their produce in Australia.Read moreRead less

The project’s goal is to improve crop breeding for increased efficiency of acquiring soil resources. Increasing a crop’s efficiency in capturing soil resources (water and nutrients) is an imperative task in ensuring food security. This project plans to use barley as the model cereal crop and characterise root traits in a panel of cultivars assembled to represent maximum diversity as well as in biparental mapping population followed by association and linkage mapping to identify genetic markers linked with specific root traits. These markers will be incorporated into a computer model of 3-D root structure and function. The enhanced computer model would be able to simulate optimal root systems for specific environments and generate a list of selectable root-trait markers.Read moreRead less

This outcome is significant as there is a huge need for new pesticidal agents that exhibit wide safety margins, reduce problems associated with resistance to existing treatments, and that are safe for the environment.Read moreRead less
Physiological and molecular characterisation of salinity tolerance in chickpea. Chickpea is a grain legume often grown in rotation with cereal crops to enhance profitability and environmental sustainability of broadacre cropping systems in Australia, and elsewhere. Chickpea is sensitive to salinity, and thus can not be grown on soils affected even by mild salinity. Limited grain legume options currently exist for these soils. This project will improve salt tolerance in chickpea and thus allow it ....Physiological and molecular characterisation of salinity tolerance in chickpea. Chickpea is a grain legume often grown in rotation with cereal crops to enhance profitability and environmental sustainability of broadacre cropping systems in Australia, and elsewhere. Chickpea is sensitive to salinity, and thus can not be grown on soils affected even by mild salinity. Limited grain legume options currently exist for these soils. This project will improve salt tolerance in chickpea and thus allow it to be grown in areas too saline for current cultivars. The research contributes to the National Research Priority of 'An Environmentally Sustainable Australia', as new cultivars of chickpea with improved salt tolerance will enhance the profitability and sustainability of rotational cropping systems in Australia.Read moreRead less
