Tailoring cellulose properties by manipulating cellulose synthase. Cellulose, a highly abundant polymer produced by plants, has many existing uses in Australian fibre and polymer industries and potential uses as, for example, an abundant feedstuff for biomass conversion into ethanol and other high value products. The optimal properties for different applications vary so that, for example, high crystallinity cellulose gives strong fibres whereas low crystallinity cellulose dissolves in gentler so ....Tailoring cellulose properties by manipulating cellulose synthase. Cellulose, a highly abundant polymer produced by plants, has many existing uses in Australian fibre and polymer industries and potential uses as, for example, an abundant feedstuff for biomass conversion into ethanol and other high value products. The optimal properties for different applications vary so that, for example, high crystallinity cellulose gives strong fibres whereas low crystallinity cellulose dissolves in gentler solvents on the way to producing cellulose-based polymers. By exploring ways to adjust the properties of celluloses for use in different applications, we can deliver potential benefits to primary producers, industries and the environment.

Discovery of new genes for plant cellulose biosynthesis and improved fibre production. Cellulose, the world's most abundant biopolymer, is important to the cotton and forest industries and for human and animal nutrition. Before biotechnology can manipulate cellulose, we must identify the enzymes of the synthesis pathway and understand how their properties determine the properties of the cellulose they produce. Not all enzymes are known and any relationships to cellulose properties remain unexplo ....Discovery of new genes for plant cellulose biosynthesis and improved fibre production. Cellulose, the world's most abundant biopolymer, is important to the cotton and forest industries and for human and animal nutrition. Before biotechnology can manipulate cellulose, we must identify the enzymes of the synthesis pathway and understand how their properties determine the properties of the cellulose they produce. Not all enzymes are known and any relationships to cellulose properties remain unexplored. This study extends our successful mutational analysis of cellulose synthesis in Arabidopsis and initiates the molecular analysis of organisms making cellulose with distinctive properties. It will significantly advance knowledge of cellulose biosynthesis and identify novel genes for fibre improvement.Read moreRead less
Pancreatic Differentiation of Cord Blood Stem Cells using Smart Surfaces. Cord blood cells obtained at the time of delivery of a baby are a valuable resource that have the potential to develop into many cell types. This Project entails attaching stem cells derived from cord blood to appropriate 3 dimensional smart surfaces, and examining the ability of such cells to develop into insulin-producing cells. An understanding of how to coax stem cells, seeded on to smart surfaces, to develop into ma ....Pancreatic Differentiation of Cord Blood Stem Cells using Smart Surfaces.

As well, it enhance the potential usefulness of cord blood for research purposes. Read moreRead less
Blood component interactions with polysaccharide biomaterials for vascular applications. Heart disease is the major killer of people in Australia and the Western world. It is due mainly to the blockage of vessels supplying the muscle of the heart with blood and nutrients, which can be replaced or by-passed but the supply of native vessels in the body is limited. Tissue engineering laboratories have been trying to develop blood vessels for this use for many years without significant success. T ....Blood component interactions with polysaccharide biomaterials for vascular applications. Heart disease is the major killer of people in Australia and the Western world. It is due mainly to the blockage of vessels supplying the muscle of the heart with blood and nutrients, which can be replaced or by-passed but the supply of native vessels in the body is limited. Tissue engineering laboratories have been trying to develop blood vessels for this use for many years without significant success. This application plans to understand the molecular signals contained within the sugar sequences used in a commonly used biomaterial chitosan that may be used in the construction of synthetic vascular grafts. If we can understand how blood cells interact with this biomaterial, we may be able to develop a blood vessel in the laboratory.Read moreRead less
Red Cell Polymorphisms and Malaria. Certain red blood cell disorders have been associated with innate protection against malaria infection. However many early studies were inconclusive. We intend to carry out a comprehensive study to investigate the effect of red blood cell differences on the invasion and/or growth of Plasmodium falciparum in vitro using improved techniques. Identification of red cell components involved in interaction with P.falciparum would give a better understanding of host ....Red Cell Polymorphisms and Malaria. Certain red blood cell disorders have been associated with innate protection against malaria infection. However many early studies were inconclusive. We intend to carry out a comprehensive study to investigate the effect of red blood cell differences on the invasion and/or growth of Plasmodium falciparum in vitro using improved techniques. Identification of red cell components involved in interaction with P.falciparum would give a better understanding of host parasite interactions which may in turn suggest novel approaches or pathways to persue. This may eventually lead to the development of novel therapeutics.

This project will devise nucleic acid and serology methods for detection of Olpidium brassicae, vector of lettuce big-vein disease (LBVD), during various phases of lettuce seedling production in nursery environments. It will be the first study to develop sustainable and environmentally responsible nursery best-practice protocols for integrated management of O. brassicae in routine seedling production and for management within the lettuce industry. These protocols will ensure that the spread of LBVD from contaminated lettuce nurseries to farms is prevented. It will also be a unique study of the establishment of a disease in new land with different soils and agricultural practices.Read moreRead less

This project represents a collaborative effort between Melbourne University, the Department of Defense and Akzo Nobel to develop new, environmentally friendly strategies to modify and/or prevent marine slime adhesion in anti-foul coatings or paint. Fouling by diatom slimes occurs at great expense to industry and the Australian Navy, adding up to 60% annually to the cost of propulsive fuel consumption in shipping. We will characterize the chemical and physical properties of the slime adhesives in order to understand how organisms control adhesion, and use these principles to develop new technology, anti-foul paints.Read moreRead less
