Genetic and environmental basis for endosperm hardness in malting barley. Barleys with a hard endosperm do not malt as well as other barleys, leading to under-modified malt. While malts may appear to be satisfactory by bulk chemical analysis, even relatively small amounts of under-modified malt causes problems in the brewing industry, such as slow filtration rates and increasing haze formation. We aim to examine two new procedures potentially useful in determining heterogeneity in barley hardn ....Genetic and environmental basis for endosperm hardness in malting barley. Barleys with a hard endosperm do not malt as well as other barleys, leading to under-modified malt. While malts may appear to be satisfactory by bulk chemical analysis, even relatively small amounts of under-modified malt causes problems in the brewing industry, such as slow filtration rates and increasing haze formation. We aim to examine two new procedures potentially useful in determining heterogeneity in barley hardness by examining single kernels, and investigating the role of barley variety and growing conditions on hardness.This project will aid in the production and selection of more uniform barleys for the malting and brewing industries.Read moreRead less
How is the plant genome reactivated and controlled during seed germination? This project aims to determine the mechanisms by which plant genomes are regulated during seed germination. The genomes of cells in mature, inactive seeds are repressed, but later must be rapidly reactivated to allow the gene expression that drives early seedling growth and development. This project will study proteins that turn genes on and off, and how these interact with the structure of DNA, in order to understand ho ....How is the plant genome reactivated and controlled during seed germination? This project aims to determine the mechanisms by which plant genomes are regulated during seed germination. The genomes of cells in mature, inactive seeds are repressed, but later must be rapidly reactivated to allow the gene expression that drives early seedling growth and development. This project will study proteins that turn genes on and off, and how these interact with the structure of DNA, in order to understand how spatial and temporal patterns of gene expression are controlled. It will advance our understanding of genome regulatory programs controlling germination and growth, and how they vary between Arabidopsis and barley. This can improve our ability to manipulate seed behaviour which would benefit growers and producers. Read moreRead less
Novel biological and genetic disease control tools for the barley industry. This project places Australian barley breeders at the forefront of disease resistance by providing them with novel tools to develop varieties with enhanced protection against fungal diseases. The aims are to produce fungal strains with multiple virulence genes for fast and cost-effective testing of barley lines, untangle the fungal/host gene interaction for resistance breeding and identify new sources of resistance. The ....Novel biological and genetic disease control tools for the barley industry. This project places Australian barley breeders at the forefront of disease resistance by providing them with novel tools to develop varieties with enhanced protection against fungal diseases. The aims are to produce fungal strains with multiple virulence genes for fast and cost-effective testing of barley lines, untangle the fungal/host gene interaction for resistance breeding and identify new sources of resistance. The outcomes will lead to the commercialisation by Australian breeding companies of barley varieties with durable fungal resistance. This will benefit the Australian economy by providing sustainability and protection for barley breeding thereby significantly reducing crop losses for this important global agricultural commodity.Read moreRead less
Control points in nitrogen uptake: enhancing the response of cereals to nitrogen supply and demand. Vast amounts of nitrogen fertiliser are applied to cereal crops to maintain yields. By uncovering what limits nitrogen uptake in cereals, this project will provide the scientific basis for improving nitrogen use efficiency and decreasing fertiliser use, with significant economic and environmental benefits.

Summary
Unlocking The Agricultural Potential Of The Dark Genome. Sustaining competitive agricultural production in the face of climate change demands more resilient, diverse, and adaptable crop varieties. Studies on the genes of crop plants have had huge benefits for agriculture, but genes themselves make up only a tiny fraction of the genome. It has until recently been impossible to assemble the 'dark' space between genes. Using ultra-modern barley genomes, this project aims to harness information from ....Unlocking The Agricultural Potential Of The Dark Genome. Sustaining competitive agricultural production in the face of climate change demands more resilient, diverse, and adaptable crop varieties. Studies on the genes of crop plants have had huge benefits for agriculture, but genes themselves make up only a tiny fraction of the genome. It has until recently been impossible to assemble the 'dark' space between genes. Using ultra-modern barley genomes, this project aims to harness information from the dark genome to (i) discover new genes with agricultural importance, (ii) illuminate invisible genomic features that can slow down plant breeding programs, and (iii) identify opportunities to transfer useful new genes into the cultivated gene pool.Read moreRead less
Physiology and genetics of barley grain germination in the malting and brewing industries. An international research team will provide new scientific information on barley grain germination. This detailed basic knowledge will be immediately applied in breeding programs that are aimed at improving malting and brewing quality in a commercial context. At the same time, the industry's carbon footprint will be significantly reduced.
Adding value to waste products from the brewing industry. Adding value to waste products from the brewing industry. This project aims to extract value from spent barley grains, the major by-product of the brewing industry. Currently sold as animal feed, this waste stream is a raw source of valuable carbohydrates and proteins for functional foods, packaging materials and liquid biofuels.

Adding value to waste products from the brewing industry. This project aims to extract value from spent barley grains, the major by-product of the brewing industry. Currently sold as animal feed, this waste stream is a raw source of valuable carbohydrates and proteins for functional foods, packaging materials and liquid biofuels. This project will combine multidisciplinary approaches to characterise spent grain components and optimise release of bioactive molecules for use as prebiotics, antioxidants, nutraceuticals, and modifiers of beer quality. The research is expected to generate resources for studying barley grain, intellectual property, patents and new in-line processes for the brewing industry.Read moreRead less
Mitochondrial Biogenesis and Signalling in Plants . This proposal aims to define the mechanisms of how mitochondrial growth and stress signalling interact and are regulated. Mitochondria are central machines in cells that use energy obtained through photosynthesis to drive growth and also play an important role in sensing and responding to non-optimal environmental growth conditions. As mitochondrial growth and stress signalling are antagonistic, growth is retarded when stress signalling is acti ....Mitochondrial Biogenesis and Signalling in Plants . This proposal aims to define the mechanisms of how mitochondrial growth and stress signalling interact and are regulated. Mitochondria are central machines in cells that use energy obtained through photosynthesis to drive growth and also play an important role in sensing and responding to non-optimal environmental growth conditions. As mitochondrial growth and stress signalling are antagonistic, growth is retarded when stress signalling is activated. Thus, the outcomes will be new knowledge and understanding of how plants balance growth and stress responses. This benefit of this knowledge and understanding is that it can be used to pursue novel avenues to optimise crop performance in changing and adverse environments.Read moreRead less
Reconstructing wheat evolution using ancient DNA. The domestication of wild grasses by farmers was a step change in human history; it led to the emergence of modern cereals and with them, western civilisation. This project will apply modern DNA sequencing methods to 5000-year-old cereal seeds to reconstruct the history of wheat, barley and other crops, and identify lost ancient forms and diversity.
