Organisation, expression and diversity of the sub-telomeric regions of the ancient eukaryote, Giardia duodenalis. We propose to extend our findings on the extreme plasticity of the structure and organisation of the sub-telomeric region of the complete genome of Giardia by more extensive chromosome walking, and comparison of different isolates. These regions are subject to gene conversion, transcriptional silencing, gene mobility, recombination, variable surface protein expression, subtelomeric i ....Organisation, expression and diversity of the sub-telomeric regions of the ancient eukaryote, Giardia duodenalis. We propose to extend our findings on the extreme plasticity of the structure and organisation of the sub-telomeric region of the complete genome of Giardia by more extensive chromosome walking, and comparison of different isolates. These regions are subject to gene conversion, transcriptional silencing, gene mobility, recombination, variable surface protein expression, subtelomeric instability and the insertion of transposable elements, a dynamic balance between structural conservation and rapid evolution. This is a rare opportunity to understand the forces at work in moulding eukaryotic sub-telomeric sequences because Giardia is not constrained by sexual homogenisation and the dynamic variability is retained.Read moreRead less
Kingdom switching microbial pathogens: the bioinformatics of mutation in the genomes of viruses and bacteria affecting crops, livestock and people. Some organisms that cause infectious diseases have moved between plants and vertebrates, either recently or repeatedly over evolutionary time. Switching between plants and vertebrates strongly influences the way these microbes mutate and evolve. We will search the genomic sequence databases for information about how the choice of host influences muta ....Kingdom switching microbial pathogens: the bioinformatics of mutation in the genomes of viruses and bacteria affecting crops, livestock and people. Some organisms that cause infectious diseases have moved between plants and vertebrates, either recently or repeatedly over evolutionary time. Switching between plants and vertebrates strongly influences the way these microbes mutate and evolve. We will search the genomic sequence databases for information about how the choice of host influences mutations in viral and bacterial genomes and model the evolutionary processes involved. This project will advance our understanding of the fine structure of microbial genomes and the importance of selection pressures on genes. It will lead to better disease management strategies for humans, and for domestic crops and livestock.Read moreRead less

The candidate is an international scientific leader, in terms of his own research, his responsibilities within the United States Department of Energy (DoE) and his role as Chair of the International Union of Pure and Applied Physics (IUPAP) Working Group on International Cooperation in Nuclear Physics. His return to South Australia to establish a major new research centre in the physical sciences will dramatically enhance the State's reputation in science and engineering, an essential component of its contribution to the nation's defence. It will underline Australia's commitment to contribute its share to advancing fundamental science. The involvement of senior researchers from fields as diverse as applied optics and mathematical biology will ensure that the opportunities for cross-disciplinary research are fully exploited.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
