Multi-functional probes for global analysis of proteome stress in cells. This project aims to create a suite of multi-functional chemical probes to identify damaged proteins that undergo unfolding or specific modifications in cells under stress. These probes will not only generate fluorescence responses to reflect on protein quality control capacity but allow associated proteins and their networks to be identified in complex cellular environments, which is difficult to achieve by current methods ....Multi-functional probes for global analysis of proteome stress in cells. This project aims to create a suite of multi-functional chemical probes to identify damaged proteins that undergo unfolding or specific modifications in cells under stress. These probes will not only generate fluorescence responses to reflect on protein quality control capacity but allow associated proteins and their networks to be identified in complex cellular environments, which is difficult to achieve by current methods. The expected outcome is to deliver new methodology for a comprehensive understanding of the correlation between quality control machinery, stress responses and cell functions. This should provide significant benefits, including contributing to fundamental knowledge on the molecular causes of neurodegenerative diseases.Read moreRead less

Structure and metabolism of bioactive carbohydrates from brown algae. Brown algae produce a diversity of species-specific carbohydrates in their cell walls that exhibit a variety of biological activities that can be exploited for the development of functional food and biopharmaceutical formulations. However, the metabolic pathways responsible for the biosynthesis of these carbohydrates are poorly characterised. This multidisciplinary project aims to understand the molecular events that control t ....Structure and metabolism of bioactive carbohydrates from brown algae. Brown algae produce a diversity of species-specific carbohydrates in their cell walls that exhibit a variety of biological activities that can be exploited for the development of functional food and biopharmaceutical formulations. However, the metabolic pathways responsible for the biosynthesis of these carbohydrates are poorly characterised. This multidisciplinary project aims to understand the molecular events that control the structure and metabolism of bioactive carbohydrates in the prominent Australian brown alga Ecklonia radiata, with particular focus on alginates and fucoidans. This knowledge will be used to produce in yeast bioactive oligosaccharides that are of high commercial interest to the biopharmaceutical industry.Read moreRead less
The colour of cellular aging: a deep probe of cellular processes. Understanding why we age and whether aging is preventable are profound research challenges, which must be first tackled at a cellular level. Building on our advances in non-invasive colour monitoring of cell function, this project aims to uncover intimate links between cellular processes and aging in cells that must survive for many decades such as oocytes and neurons. We will explore the tantalising possibility to rejuvenate such ....The colour of cellular aging: a deep probe of cellular processes. Understanding why we age and whether aging is preventable are profound research challenges, which must be first tackled at a cellular level. Building on our advances in non-invasive colour monitoring of cell function, this project aims to uncover intimate links between cellular processes and aging in cells that must survive for many decades such as oocytes and neurons. We will explore the tantalising possibility to rejuvenate such aged cells by interfering with molecular master switches of aging. A unique machine learning approach will be applied for finding the most effective interventions. The results will have broad impact beyond the science of aging, in the areas of female fertility, neurodegeneration and immunity.

Understanding chaperone function, one molecule at a time. This project aims to determine how molecular chaperones, a class of proteins represented in all phyla of life, work together to keep proteins folded and functional, particularly following cellular stress. This is important as proteins are involved in virtually all biological processes. This project will exploit innovative microscopy techniques to watch these molecular chaperones as they work. Expected outcomes of this project are the firs ....Understanding chaperone function, one molecule at a time. This project aims to determine how molecular chaperones, a class of proteins represented in all phyla of life, work together to keep proteins folded and functional, particularly following cellular stress. This is important as proteins are involved in virtually all biological processes. This project will exploit innovative microscopy techniques to watch these molecular chaperones as they work. Expected outcomes of this project are the first definitive description of how molecular chaperones interact to refold proteins, and the development of novel methods to study dynamic biological processes. This should provide significant benefits including enhanced collaboration and scientific capacity in Australia.Read moreRead less
Characterising the transport and delivery of oligonucleotides . Short RNA and DNA molecules represent a class of macromolecules that have great potential, but to facilitate their trafficking across cellular and membrane barriers into specific sites of action is challenging. This project aims to develop and apply novel imaging approaches to track them in cells and tissues. Expected outcomes include better understanding of the trafficking across cellular and membrane barriers, and improved imaging ....Characterising the transport and delivery of oligonucleotides .

This project aims to develop and apply novel imaging approaches to track them in cells and tissues. Expected outcomes include better understanding of the trafficking across cellular and membrane barriers, and improved imaging tools that could be used to further study the molecular mechanisms of accumulation, metabolism and trafficking of these molecules. This project should provide new strategies to target these molecules to specific cells and tissues, which have significant social and economic benefits to the Australian community.Read moreRead less
Phosphorus-efficient Australian plants: applications for crop improvement. This project aims to investigate ways to improve the phosphorus (P) efficiency of selected crops (Lupinus) in Australia.

This project aims to investigate ways to improve the phosphorus (P) efficiency of selected crops (Lupinus) in Australia. The phosphorus impoverished soils in Australia has allowed the evolution of plants that are highly efficient at acquiring and using phosphorus. Increasing understanding of highly-efficient phosphorus use mechanisms at the physiological, biochemical, anatomical and molecular biological levels will provide knowledge of traits to guide breeding efforts to develop more phosphorus efficient crops that can perform well in P-limited environments; an outstanding strategy to balance the phosphorus demand for increasing global food production with gradually decreasing non-renewable phosphorus reserves. An expected outcome of this project is to develop crops better able to use scarce phosphorus.Read moreRead less
