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.
Australia, the centre of diversity and the centre of origin of rice? Wild relatives of rice are found across northern Australia. The project aims to apply emerging technologies for efficient whole genome sequencing to determination of the genetic diversity of these populations in relation to cultivated rice and wild rice from other parts of the world.

Wild relatives of rice are found across northern Australia. The project aims to apply emerging technologies for efficient whole genome sequencing to determination of the genetic diversity of these populations in relation to cultivated rice and wild rice from other parts of the world. The role of the Australian populations in the evolution of rice and the potential of these populations to contribute valuable diversity to rice crops worldwide are intended to be analysed. The impact of domestication on rice in Asia is expected to be established by the characterisation of the related Australian populations that were isolated from the impacts of agriculture for around 7000 years. Whole genome associations with environment may provide clues to adapting agriculture to climate.Read moreRead less
Stomata functioning in halophytes for improved plant stress tolerance. This project aims to determine how halophytes balance photosynthesis and water loss under extreme soil conditions. Salinity and drought affect crop production. Plants’ ability to balance carbon dioxide uptake and water loss through stomata determines how they cope with stressors. Halophytes can achieve this balance at conditions that normally kill 99% of crops, but how they do so is unknown. This project will characterise the ....Stomata functioning in halophytes for improved plant stress tolerance. This project aims to determine how halophytes balance photosynthesis and water loss under extreme soil conditions. Salinity and drought affect crop production. Plants’ ability to balance carbon dioxide uptake and water loss through stomata determines how they cope with stressors. Halophytes can achieve this balance at conditions that normally kill 99% of crops, but how they do so is unknown. This project will characterise the transport systems mediating stomata function in halophytes and contribute to understanding the molecular and physiological basis of their operation. This should allow breeders to use this trait to improve crop performance under conditions of extreme salinity and drought.Read moreRead less

This project aims to establish a breeding program for Plantago ovata in Australia to provide a reliable supply of high quality, superior psyllium as a key ingredient in the gluten-free food industry, providing benefits to the industrial partner, growers in Australia and consumers. Target traits include better harvest index, reduced seed shattering and identification of lines carrying psyllium with novel properties or whole seeds that can be ground and used as flour that imparts less intense colour changes or effects on loaf structure, and which may be highly suitable for other baked gluten-free products. The fundamental knowledge gained from the genetic and biochemical anlayses of these lines will also broadly benefit seed biology research.Read moreRead less
Australia's native sorghums: a model for testing plant adaptation theories. This proposal tests an emerging theory that allocation of resources by plants to growth or defence are interrelated, not alternatives as currently assumed. Like many crops, sorghum produces toxic cyanide, especially during droughts but its wild relatives make much less. This project aims to discover why cyanide is so common in domesticated plants and why levels increase with stress. This has important implications for de ....Australia's native sorghums: a model for testing plant adaptation theories. This proposal tests an emerging theory that allocation of resources by plants to growth or defence are interrelated, not alternatives as currently assumed. Like many crops, sorghum produces toxic cyanide, especially during droughts but its wild relatives make much less. This project aims to discover why cyanide is so common in domesticated plants and why levels increase with stress. This has important implications for developing crops that are high yielding and also climate resilient. Expected outcomes include full genome sequences for all of Australia’s unique native sorghums, confirmation of new theories on the interrelationships between defence and growth and identification of new traits vital for developing the crops of the future.

The project aims to identify genes and molecular processes that regulate inflorescence architecture in wheat, using state-of-the-art genetic resources to identify novel biological mechanisms that regulate the development of spikelets – reproductive branches that contain grain-producing florets. The research is highly significant as little is known about how spikelet and floret numbers are determined genetically in wheat, and new traits need to be identified to increase yields for the world’s growing population. Project outcomes will include new insights into the biology that underpins grain production of wheat, with expected benefits enabling sustainable increases of yields by breeders and growers to help bolster global food security.Read moreRead less
Breaking the nexus: more biomass in cereal grain. Grain yield is controlled by complex, regulated genetic networks or quantitative trait loci (QTLs) derived from natural variations in many crop plants. Yield is a product of the three major parameters: panicle number, grain number and grain size, trade-offs are commonly observed between grain number and size. There is evidence to suggest it is possible to improve grain size without altering overall biomass. With the genomic and genetic resource t ....Breaking the nexus: more biomass in cereal grain. Grain yield is controlled by complex, regulated genetic networks or quantitative trait loci (QTLs) derived from natural variations in many crop plants. Yield is a product of the three major parameters: panicle number, grain number and grain size, trade-offs are commonly observed between grain number and size. There is evidence to suggest it is possible to improve grain size without altering overall biomass. With the genomic and genetic resource tools at hand. This project will elucidate the genetic architecture of grain size, and manipulate the key loci to generate more biomass in the grain, minimising or eliminating the adverse impact on seed number. This will maximise harvestable yield without imposing increased demand for water and nutrients.Read moreRead less
