Why is most of the genetic variance for complex traits undetected by large powerful screens of common variants? The genomics revolution has made it possible to measure thousands of DNA variants in individuals. These variants have been associated with phenotypic outcomes in a range of species. Paradoxically, even very large studies have only accounted for a fraction of the resemblance between relatives that we know exist. Our study will test three specific hypotheses to explain this paradox. A be ....Why is most of the genetic variance for complex traits undetected by large powerful screens of common variants? The genomics revolution has made it possible to measure thousands of DNA variants in individuals. These variants have been associated with phenotypic outcomes in a range of species. Paradoxically, even very large studies have only accounted for a fraction of the resemblance between relatives that we know exist. Our study will test three specific hypotheses to explain this paradox. A better understanding about the genetic architecture for complex traits will improve the efficiency of gene mapping methods, including applications in humans for traits related to productive ageing and a healthy start to life, will lead to more efficient selection programs in agricultural populations and will inform us with respect to past evolutionary events.Read moreRead less
Dissociation of a Tetrameric Enzyme with Interface-Targeted Peptides. With antibiotic resistance on the rise, there is an urgent need to develop new antibiotics and an equally urgent need to characterise new antibiotic targets. One such target is dihydrodipicolinate synthase (DHDPS) which catalyses the critical step in lysine and cell wall biosynthesis in bacteria. This proposal aims to generate new drugs targeting DHDPS for effective and rapid treatment of bacterial infections, including gastro ....Dissociation of a Tetrameric Enzyme with Interface-Targeted Peptides. With antibiotic resistance on the rise, there is an urgent need to develop new antibiotics and an equally urgent need to characterise new antibiotic targets. One such target is dihydrodipicolinate synthase (DHDPS) which catalyses the critical step in lysine and cell wall biosynthesis in bacteria. This proposal aims to generate new drugs targeting DHDPS for effective and rapid treatment of bacterial infections, including gastroenteritis. Recent statistics show that over 5 million Australians suffer from gastroenteritis each year and hospitalisation for this infection is nearly seven times higher for indigenous than non-indigenous children. Accordingly, this research has the potential to assure a healthier future for millions of Australians.Read moreRead less
Inhibitors of meso-diaminopimelic acid (meso-DAP) and lysine biosynthesis: targeting dihydrodipicolinate synthase. With antibiotic resistance on the rise, there is an urgent need to develop new antibiotics with novel modes of action. This project aims to generate new drug candidates that target dihydrodipicolinate synthase (DHDPS) - the first enzyme in the synthesis of the bacterial cell wall - using a triple-pronged approach. This novel approach will allow for the development of new drugs to tr ....Inhibitors of meso-diaminopimelic acid (meso-DAP) and lysine biosynthesis: targeting dihydrodipicolinate synthase. With antibiotic resistance on the rise, there is an urgent need to develop new antibiotics with novel modes of action. This project aims to generate new drug candidates that target dihydrodipicolinate synthase (DHDPS) - the first enzyme in the synthesis of the bacterial cell wall - using a triple-pronged approach. This novel approach will allow for the development of new drugs to treat a range of pathogenic bacteria, including "Golden Staph".Read moreRead less

Summary
A 5-D Correlative Imaging Platform: Combining the strengths of light and electron microscopy. This will be Australia's first dedicated five-dimensional multiphoton-microscopy platform, allowing observation of dynamic structures across different length and time scales under controlled temperatures, followed by high-resolution electron microscopy studies on the same samples. This platform will provide a unique characterisation tool to Australia's top-flight investigators, and so contribute to the ....A 5-D Correlative Imaging Platform: Combining the strengths of light and electron microscopy. This will be Australia's first dedicated five-dimensional multiphoton-microscopy platform, allowing observation of dynamic structures across different length and time scales under controlled temperatures, followed by high-resolution electron microscopy studies on the same samples. This platform will provide a unique characterisation tool to Australia's top-flight investigators, and so contribute to the nation's research priorities. It will enable: fundamental studies of cancer, neural diseases and immune disorders; the development of frontier technologies, such as smart nanomaterials, biosensors and targeted drug delivery; and applied research to help plants and soils adapt to climate variability, and to increase sustainable use of water.Read moreRead less
