Development of symbiont based approaches to pest and disease control in sugarcane. This project aims to develop a new approach to the control of insect damage to sugarcane in Australia. It focuses on the manipulation of bacteria that are intimately associated with insects that feed on sugarcane, so as to decrease their ability to cause crop damage both directly through feeding and indirectly through the transmission of disease
Development of solvent extraction systems for improved sugar quality and yield. The recent collapse in the international sugar price and increased competition amongst producers have highlighted the vulnerability of Australian sugar mills and the regional communities reliant on sugar cane growing to variation in the price of this commodity. Hence, the development of new, more efficient means to produce raw sugar of high quality is of paramount importance to maintain Australia as a low cost produ ....Development of solvent extraction systems for improved sugar quality and yield. The recent collapse in the international sugar price and increased competition amongst producers have highlighted the vulnerability of Australian sugar mills and the regional communities reliant on sugar cane growing to variation in the price of this commodity. Hence, the development of new, more efficient means to produce raw sugar of high quality is of paramount importance to maintain Australia as a low cost producer. This project aims to investigate the use of unique solvent extraction methods to remove deleterious impurities from the raw cane juice in sugar mills with the consequent improvement in both sugar yield and quality.Read moreRead less

Manipulation of carbon partitioning to enhance the value of sugarcane. This project aims to develop enhanced varieties of sugarcane, a highly efficient crop for capturing carbon in plant biomass. This project will use genomic and metabolomic tools to investigate the biochemical and molecular genetic control of carbon partitioning into the major components of sugarcane biomass; identify key genetic controls of sucrose, cellulose, hemicellulose and lignin biosynthesis; and establish strategies for genetic selection of sugarcane genotypes with desirable biomass components. Anticipated outcomes are an optimised industrial sugarcane crops with higher sugar content and other biomass components designed for high value end uses such as bio-energy or bio-material production.Read moreRead less

Understanding an exotic disease: Initiation of sex and infection by the sugarcane smut Ustilago scitaminea. Australian sugar exports generate almost $2 billion in annual sales, making the sugar industry a critical facet of the Australian economy. In 2006, Australia's primary sugar producing region came under threat when an outbreak of sugarcane smut caused by the fungus Ustilago scitaminea first appeared in Queensland. Management of this potentially devastating disease has focused on breeding pr ....Understanding an exotic disease: Initiation of sex and infection by the sugarcane smut Ustilago scitaminea. Australian sugar exports generate almost $2 billion in annual sales, making the sugar industry a critical facet of the Australian economy. In 2006, Australia's primary sugar producing region came under threat when an outbreak of sugarcane smut caused by the fungus Ustilago scitaminea first appeared in Queensland. Management of this potentially devastating disease has focused on breeding programmes aimed at developing resistant sugarcane cultivars, a complex process hampered by a lack of information about the mechanisms of smut resistance. Our research will provide key insight into the mechanisms by which U. scitaminea infects sugarcane, directing future breeding efforts and protecting this valuable industry against further outbreaks.Read moreRead less

This will provide the first tools to readily measure the full size distribution of starch in industry laboratories, giving far more information than is currently accessible. The data will be extremely sensitive to structural characteristics associated with desirable end-use properties. The new process will enable conventional instrumentation methodology to be re-engineered to better select starch-containing materials. This will enable superior targeting and processing of materials for improved products in human nutrition, animal feed and manufactured goods such as biodegradable plastics.Read moreRead less
A New Window into Transgene Silencing in Plants: mechanisms of copy-number independent, 5' sequence dependent, post-transcriptional silencing in a complex polyploid. Silencing of introduced genes is a major problem limiting plant molecular improvement. Sugarcane, a complex polyploid, shows the most efficient transgene silencing ever observed in plants. Silencing operates on the RNA, depends on the upstream sequence of the gene, and is independent of copy number. Other plant species develop endop ....A New Window into Transgene Silencing in Plants: mechanisms of copy-number independent, 5' sequence dependent, post-transcriptional silencing in a complex polyploid. Silencing of introduced genes is a major problem limiting plant molecular improvement. Sugarcane, a complex polyploid, shows the most efficient transgene silencing ever observed in plants. Silencing operates on the RNA, depends on the upstream sequence of the gene, and is independent of copy number. Other plant species develop endopolyploidy with age, and show unpredictable or patchy silencing. We speculate that differential silencing is a natural control mechanism in the exploitation of polyploidy in plants. The sugarcane system provides an exceptional opportunity to identify the sequences that trigger and protect from silencing, and to develop approaches to avoid the problem.Read moreRead less

Sugarcane is one of Australia's most important rural industries. However, as a single product industry, declining sugar prices threaten the industry's long term economic sustainability unless alternative markets for sugarcane are created. Utilising the sugarcane waste for cellulosic ethanol would provide a new revenue stream, injecting life into the Australian sugarcane industry. In addition, cellulosic ethanol from sugarcane has the potential to substantially decrease the cost of biofuel production and significantly reduce greenhouse gas emissions. The research proposed here will advance our ability to improve sugarcane through biotechnology.Read moreRead less
