Enhancing and manipulating C4 photosynthesis. To meet the challenge of increasing crop yield for a burgeoning world population, it has become apparent that photosynthetic capacity must be increased per unit leaf area to improve yield potential. Plants with the C4 photosynthetic pathway are major contributors to world food production and bioenergy supply.

To meet the challenge of increasing crop yield for a burgeoning world population, it has become apparent that photosynthetic capacity must be increased per unit leaf area to improve yield potential. Plants with the C4 photosynthetic pathway are major contributors to world food production and bioenergy supply. The aim of this study is to explore ways of enhancing C4 photosynthesis using directed molecular modifications of Setaria viridis, the model monocot C4 species, and through high throughput fluorescence imaging of photosynthesis in Setaria italica accessions. This will provide new insights into rate limiting steps of C4 photosynthesis needed for C4 crop improvement.Read moreRead less

This project aims to increase productivity and profitability of the Australian sorghum industry in the face of risks imposed by an increasingly variable climate. This project expects to generate new knowledge of processes limiting hybrid seed production and translate this world-class research into tools and services that can be used by seed companies to improve its efficiency and reliability. The intended outcome will increase the security and sustainability of farming by minimising the risk of climate-induced seed shortages, maintaining Australia’s leadership in agricultural technology development. The expected benefits support profitable and productive businesses, providing Australian agriculture with a competitive, sustainable edge.Read moreRead less
More than defence: primary roles for cyanogenic glucosides. The tropical crop, sorghum, produces toxic cyanide to avoid being eaten by herbivores, but this diverts resources away from growth and reproduction. Using non-toxic sorghum mutants, this project seeks to explain how cyanide production is regulated and enhance agricultural efficiency in the face of climate change.

Summary
Discovering hidden control elements for crop improvement. Sustainable, productive agricultural processes are essential for tackling the challenges of tomorrow’s world. The ability to optimise beneficial agricultural traits depends on the precise control of genes in a crop plant’s enormous genome.

Sustainable, productive agricultural processes are essential for tackling the challenges of tomorrow’s world. The ability to optimise beneficial agricultural traits depends on the precise control of genes in a crop plant’s enormous genome. Yet, identifying valuable gene control regions is like looking for needles in a haystack. The location of these regions is often not obvious and current detection technologies are impractically expensive and intensive. This project aims to develop a new technology that is expected to facilitate rapid and cost-effective discovery of all the control regions in a genome, enhancing our understanding of crop genomes and unlocking new avenues for agricultural improvement, food security and economic stability.Read moreRead less
Slowly digestible, high antioxidant sorghum: a new wholegrain food paradigm to help combat type 2 diabetes. This project has the potential to lead to benefits to several sectors of the community. Government and consumers will benefit by new sorghum foods helping to reduce diabetes, heart disease and obesity and the economic and quality of life burden of these diseases; health professionals will benefit through availability of new food products to recommend for disease risk-reduction and control; ....Slowly digestible, high antioxidant sorghum: a new wholegrain food paradigm to help combat type 2 diabetes.

Drought tolerance in sorghum: the roots of the solution. This project aims to develop an efficient, cost-effective sensing platform for visualising sorghum root systems in the field. Through innovative use of above and below ground sensing technologies, this project expects to generate new knowledge on the association between root structure and improved yield stability under drought stress.

This project aims to develop an efficient, cost-effective sensing platform for visualising sorghum root systems in the field. Through innovative use of above and below ground sensing technologies, this project expects to generate new knowledge on the association between root structure and improved yield stability under drought stress. Expected outcomes include improved capacity for sorghum breeders and new digital agriculture products and services to support the industry more broadly. Given that sorghum is the main summer cereal grown in Australia, this should provide significant benefits, such as improved productivity and profitability for the Australian agriculture sector.

Wild crop relatives are an important source of traits for improving their cultivated counterparts. Analysing the diversity and evolution of Australia’s 17 native sorghum species will provide new understanding of how plants have adapted to environmental challenges across diverse Australian environments. This should provide significant benefit by providing new resources for plant breeders to produce more climate-resilient crops.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 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.

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
