Factors controlling higher-level starch structure. In a new paradigm for cereal chemistry, we will link structural and functional genomics to a mechanistic understanding of starch polymer structure. By using our novel characterization techniques, we will obtain the first data on the complex multiscale structure of starch in cereal grains that will be sensitive to the mechanisms of starch biosynthesis. These results will enable us to identify the genetic and environmental factors that, separately ....Factors controlling higher-level starch structure. In a new paradigm for cereal chemistry, we will link structural and functional genomics to a mechanistic understanding of starch polymer structure. By using our novel characterization techniques, we will obtain the first data on the complex multiscale structure of starch in cereal grains that will be sensitive to the mechanisms of starch biosynthesis. These results will enable us to identify the genetic and environmental factors that, separately and together, control starch structure in a range of cereals. This knowledge will provide a powerful tool for plant breeders and biotechnologists to produce cereals with improved properties.Read moreRead less
Graft copolymers from starch and synthetic monomers. Polymer dispersions, manufactured as latexes in large quantities in Australia and elsewhere, have myriad applications, such as in adhesives, bitumen modifiers, paints and paper coatings. This project will create the enabling science to replace by starch the current synthetic products used to stop these dispersions from coagulating. This will create new uses for renewable resources and will reduce environmental insult by avoiding the leaching o ....Graft copolymers from starch and synthetic monomers. Polymer dispersions, manufactured as latexes in large quantities in Australia and elsewhere, have myriad applications, such as in adhesives, bitumen modifiers, paints and paper coatings. This project will create the enabling science to replace by starch the current synthetic products used to stop these dispersions from coagulating. This will create new uses for renewable resources and will reduce environmental insult by avoiding the leaching of biologically incompatible chemicals. By using starch from crops suited for Australia's arid climate, the new technology will reduce both our dependence on imported products and our greenhouse gas emissions.Read moreRead less
Mechanistic characterisation of genotype x environment interactions in sorghum and arabidopsis. Sorghum is an economically important cereal crop for Australia. In Australia, sorghum is used as a staple animal feed and it is very important for the live stock industry. With the predicted changes of temperature and rainfall patterns due to climate change, negative effects on sorghum yield are expected, which can have adverse effects on Australian economy. Our studies will identify and mark genes th ....Mechanistic characterisation of genotype x environment interactions in sorghum and arabidopsis. Sorghum is an economically important cereal crop for Australia. In Australia, sorghum is used as a staple animal feed and it is very important for the live stock industry. With the predicted changes of temperature and rainfall patterns due to climate change, negative effects on sorghum yield are expected, which can have adverse effects on Australian economy. Our studies will identify and mark genes that regulate flowering and seed production in sorghum in response to changes in temperature and light interactions. These studies will help to develop novel sorghum varieties with desirable characters through plant-breeding programmes.Read moreRead less
Enabling Molecular Plant Breeding for Drought Adaptation Using Genome-to-Phenome Modelling Technologies. Effective molecular plant breeding for improved water productivity of sorghum would generate significant economic and social benefits for rural communities in NE Australia.

Effective molecular plant breeding for improved water productivity of sorghum would generate significant economic and social benefits for rural communities in NE Australia. There is a significant opportunity to expand the sorghum industry in the region. Despite the global financial crisis, global demand for meat continues to increase, generating strong demand from intensive livestock industries for feed grain. Price is projected to return to high levels given continuing use of major feed grains for biofuel. A 10% increase in sorghum production would add net value of $48M annually, much via employment. The scientific content of this project positions Australia at the leading edge globally in this emerging research field. Read moreRead less
Targeted approaches to improve nitrogen use efficiency in maize. Nitrogen is an essential input required for growing high yielding quality cereal crops such as maize and wheat. Unfortunately, excessive use of nitrogen fertilizers can lead to serious environmental costs including nitrogen pollution through leaching and the significant cost in non-renewable fossil fuels used in their production. Improving nitrogen use efficiency in crops such as maize will reduce fertilizer use while ensuring lo ....Targeted approaches to improve nitrogen use efficiency in maize. Nitrogen is an essential input required for growing high yielding quality cereal crops such as maize and wheat. Unfortunately, excessive use of nitrogen fertilizers can lead to serious environmental costs including nitrogen pollution through leaching and the significant cost in non-renewable fossil fuels used in their production. Improving nitrogen use efficiency in crops such as maize will reduce fertilizer use while ensuring long-term sustainable production and harvestable yields. This collaboration with DuPont-Pioneer will focus on identifying nitrogen-linked traits in Maize that will be incorporated into new lines targeted at reducing grower dependence on nitrogen fertilizers.Read moreRead less
Investigating a new paradigm for plant-pathogen interactions; Identification of host-selective toxin proteins in the wheat pathogen Stagonospora nodorum. Stagonospora nodorum is a fungus that causes leaf and glume blotch disease on wheat. This disease alone causes $55 million dollars in yield losses per annum. Traditional breeding methods have yielded crops that are only mildly resistant leaving control of the disease to be worryingly reliant on fungicides. This project aims to identify and char ....Investigating a new paradigm for plant-pathogen interactions; Identification of host-selective toxin proteins in the wheat pathogen Stagonospora nodorum. Stagonospora nodorum is a fungus that causes leaf and glume blotch disease on wheat. This disease alone causes $55 million dollars in yield losses per annum. Traditional breeding methods have yielded crops that are only mildly resistant leaving control of the disease to be worryingly reliant on fungicides. This project aims to identify and characterise proteins that the fungus secretes to cause disease on wheat. By identifying these proteins, it is anticipated that strategies, both traditional and modern, could be employed to enable better control of the disease. This in turn would help provide a long term and secure supply of wheat and wheat based products to the community.Read moreRead less

Increasing fuel costs, finite resources and the need to develop more carbon neutral and cleaner fuels have created a need for renewable sources. Ethanol and future generation biofuels (butanol and more energy-rich alcohols) can be extracted from biomass sources. Sorghum is an ideal bioenergy feedstock in the hotter, drier areas of Northern Australia, where starch (grain), sugar and lignocellulose (stover) can be amassed in this water efficient plant. Identifying and manipulating the genes to enable the improvement of sorghum as a dedicated bioenergy crop, will enable the increased efficiency of the Australian biofuels industry and create sustainable rural industries.Read moreRead less
