Enhancing stress tolerance in plants by manipulation of properties of stress responsive transcription factors. This project will describe structural and functional properties of cereal transcription factors that are critical to plant development under hostile environmental conditions. The knowledge of the revealed molecular mechanisms of transcription factors will open avenues to developments of improved crop plants.
Genomic strategies for reducing losses during processing and improving the nutritional value of wheat in human diets. Wheat breeding requires efficient tools to allow selection of varieties with both high grain yield and good functional and nutritional value. Whole genome analysis will be used to develop screening methods to deliver wheat varieties with novel processing and nutritional properties for human diets contributing to global food and nutritional security.
Transport systems that underpin nitrogen efficient maize. This project aims to define the nitrogen transport network involved in the uptake, storage and redistribution of inorganic nitrogen (nitrate and ammonium) over the developmental life cycle of maize. This information will provide novel insight into the genetic control of nitrogen use in maize and other cereal crops.
Gene identification and functional characterization for metabolism-based herbicide resistance in Lolium rigidum. Evolution of multiple herbicide resistance is widespread in Lolium rigidum in Australia. This resistance is very often endowed by enhanced rates of herbicide metabolism (metabolic resistance) involving cytochrome P450. This project aims to identify, clone and characterise important herbicide-metabolising P450 and other genes from multiple herbicide-resistant L. rigidum biotypes, and d ....Gene identification and functional characterization for metabolism-based herbicide resistance in Lolium rigidum. Evolution of multiple herbicide resistance is widespread in Lolium rigidum in Australia. This resistance is very often endowed by enhanced rates of herbicide metabolism (metabolic resistance) involving cytochrome P450. This project aims to identify, clone and characterise important herbicide-metabolising P450 and other genes from multiple herbicide-resistant L. rigidum biotypes, and develop transcriptional and biochemical markers for metabolic resistance diagnosis. Herbicide-metabolising gene discovery, characterisation and marker development will greatly extend the currently limited knowledge and understanding of metabolic resistance and help achieve sustainable weed management.Read moreRead less
New approaches for screening cereal germplasm for enhanced microbial pathogen resistance and desirable grain texture. The trait of grain hardness (texture) is of significance to the Australian infrastructure, as exports of hard wheat contribute over 5 billion dollars per year on average to the national economy and hard wheats are also important for domestic usage. The genes responsible for grain texture also impart resistance to bacterial and fungal pathogens which can cause extensive damage. ....New approaches for screening cereal germplasm for enhanced microbial pathogen resistance and desirable grain texture. The trait of grain hardness (texture) is of significance to the Australian infrastructure, as exports of hard wheat contribute over 5 billion dollars per year on average to the national economy and hard wheats are also important for domestic usage. The genes responsible for grain texture also impart resistance to bacterial and fungal pathogens which can cause extensive damage. However, the Australian gene pool has very limited genetic diversity in grain textures and thus possibly in pathogen resistance. The project will work out the science behind these two traits and identify lines with new variants of textures and pathogen resistances, thus greatly benefiting the national infrastructure and local primary industries.Read moreRead less
Functional network analysis of plant metabolism in response to salinity and temperature through targeted proteomics. This project will measure changes in plant metabolism and provide methods and a pipeline for quantification and modelling. It will assess nitrogen linked metabolism under environmental stress experienced in Australian wheat cropping systems and build fundamental knowledge of changes in networks of nitrogen metabolism in model plants.
Advanced plant breeding and food manufacturing for healthier bread. This project aims to generate bread containing high amounts of biologically available iron through targeted manipulation of plant-derived phytonutrients at several points along the wheat-to-bread supply chain. The project expects to generate new knowledge for developing healthier bread and address consumer demands for value-added food products. Anticipated outcomes are novel plant breeding and food manufacturing techniques that ....Advanced plant breeding and food manufacturing for healthier bread. This project aims to generate bread containing high amounts of biologically available iron through targeted manipulation of plant-derived phytonutrients at several points along the wheat-to-bread supply chain. The project expects to generate new knowledge for developing healthier bread and address consumer demands for value-added food products. Anticipated outcomes are novel plant breeding and food manufacturing techniques that enhance the nutritional composition of wheat grain and bread making products, resulting in higher-value agricultural commodities and breads. The project should benefit bread retailers and crop growers involved in Australia’s $4.7 billion bread market and reduce the environmental impacts of bread production.Read moreRead less
Digging deeper to improve yield stability. This project aims to provide innovative breeding solutions that harness the ‘hidden’ part of the plant, roots, to support the development of more productive crops in the face of climate variability. The project expects to generate new insights into the biology and genetics of root development in barley, a model cereal crop, by applying cutting-edge genome editing, phenotyping and genomics technologies. Anticipated outcomes include novel methodologies to ....Digging deeper to improve yield stability. This project aims to provide innovative breeding solutions that harness the ‘hidden’ part of the plant, roots, to support the development of more productive crops in the face of climate variability. The project expects to generate new insights into the biology and genetics of root development in barley, a model cereal crop, by applying cutting-edge genome editing, phenotyping and genomics technologies. Anticipated outcomes include novel methodologies to accelerate breeding for diverse production environments, with direct applications in barley, and other major cereals including wheat and oats. This should provide significant economic and social benefits to the Australian grains industry through yield stability amidst climate variability.Read moreRead less
Small molecules with large effect: The dual role of nitrogen-containing metabolites in stress tolerance and nutrient recycling. The main objective of this project is to identify drought and nutrient-deficiency responsive pathways in tolerant wheat and to provide markers to breeding programs that facilitate selection of superior breeding lines.

The main objective of this project is to identify drought and nutrient-deficiency responsive pathways in tolerant wheat and to provide markers to breeding programs that facilitate selection of superior breeding lines. This project builds on a pilot study conducted in rice in which tolerant-specific metabolites were identified which are representative of pathways relevant for the protection of cells from damage through reactive oxygen species (ROS) and for nutrient (nitrogen, phosphorus, sugars) recycling under stress. Available data suggest that these pathways are also relevant in wheat. Quantitative metabolomics, genetics, and molecular tools will be used to deliver either DNA-based or metabolomics markers to breeders.Read moreRead less
Developing strong restorer-of-fertility genes for hybrid wheat breeding. Hybrid wheat varieties yield 10-15% more than conventional lines but a cost-effective system to produce hybrid seeds on a commercial scale is missing. This project aims to deliver such a system for use in hybrid wheat breeding programmes. The outcome will be ultimately higher wheat yield gains in Australia and worldwide. Higher and more stable yields will contribute to higher food security for the growing human population.
