Illuminating the microbial world using genome-based fluorescence microscopy. Our understanding of microbial diversity on Earth has been fundamentally changed by metagenomic characterisation of natural ecosystems. Traditional approaches for visualising microbial communities are time-consuming and provide limited information about the identity of specific microorganisms.

Our understanding of microbial diversity on Earth has been fundamentally changed by metagenomic characterisation of natural ecosystems. Traditional approaches for visualising microbial communities are time-consuming and provide limited information about the identity of specific microorganisms. The proposed research aims to combine single cell genomics and super resolution microscopy for novel, high-throughput, genome-based techniques to visualise microorganisms, plasmids and viruses, with strain level specificity. The application of these highly scalable approaches will provide comprehensive and unprecedented insight into the fine-scale dynamics and evolution of environmentally and biotechnologically important microbial communities.Read moreRead less
Unravelling a novel stress-signalling system in bacteria. This project aims to investigate the cyclic-di-AMP signalling system in industrially important bacteria. The recently discovered cyclic-di-AMP is essential for normal bacterial growth and plays key roles in heat and antibiotic resistance, metabolism and virulence. This project will develop new biological assays to shed light on how bacteria sense and respond to environmental stress. Expected outcomes include a much deeper understanding of ....Unravelling a novel stress-signalling system in bacteria. This project aims to investigate the cyclic-di-AMP signalling system in industrially important bacteria. The recently discovered cyclic-di-AMP is essential for normal bacterial growth and plays key roles in heat and antibiotic resistance, metabolism and virulence. This project will develop new biological assays to shed light on how bacteria sense and respond to environmental stress. Expected outcomes include a much deeper understanding of signalling inputs and outputs. This should lead to benefits such as guiding the improvement of bacterial strains used in food and biochemical biotechnological applications, and may provide the foundation for the development of novel antibiotics.Read moreRead less

Summary
Australian Membership of the International Ocean Discovery Program. This proposal is for an 18-month membership of the International Ocean Discovery Program (IODP), the world’s largest collaborative research program in Earth and Ocean sciences. The Program studies the history and current activity of the Earth by conducting seagoing coring expeditions and monitoring of instrumented boreholes, using globally unique infrastructure that Australians would otherwise have no access to.

This proposal is for an 18-month membership of the International Ocean Discovery Program (IODP), the world’s largest collaborative research program in Earth and Ocean sciences. The Program studies the history and current activity of the Earth by conducting seagoing coring expeditions and monitoring of instrumented boreholes, using globally unique infrastructure that Australians would otherwise have no access to. Program outcomes include understanding past global environmental change on multiple time scales, the deep biosphere, plate tectonics, formation and distribution of resources, and generation of hazards. These outcomes are paramount to Australia’s national science and research priorities, and societal and economic prosperity.Read moreRead less

For thousands of years we have used microbes to create bread, wine, cheese. Now, our Centre will pioneer new approaches to the design of synthetic microbes, enabling the development of custom-designed microbial communities, synthetic organelles and new to nature biological pathways and enzymes. CoESB will combine engineering with molecular biology to design and construct novel biological systems that can convert biomass from agriculture or waste streams to biofuel, bioplastics and other high-value chemicals.Read moreRead less
Changing the classification status quo with a global genome-based taxonomy. A grand challenge in biology is the reconstruction of the complete evolutionary history of life on our planet. A major hurdle to this goal has been the inability to culture most microbial species which comprise the bulk of evolutionary diversity. However, new molecular techniques have removed this hurdle and >1,000 new microbial species are being revealed each month through sequencing of environmental samples.

A grand challenge in biology is the reconstruction of the complete evolutionary history of life on our planet. A major hurdle to this goal has been the inability to culture most microbial species which comprise the bulk of evolutionary diversity. However, new molecular techniques have removed this hurdle and >1,000 new microbial species are being revealed each month through sequencing of environmental samples. This project aims to organise both cultured and uncultured microbial diversity into a systematic evolutionary framework to replace the current highly flawed and incomplete classification of microorganisms. The systematic classification of the microbial world is timely and will enable fundamental insights into ecology and evolution.Read moreRead less
My enemy’s enemy is my friend: The genetics of major plant pathogen killers. Fungi are devastating agents of crop diseases. These plant pathogens, in turn, are often parasitized by other fungi in the field. The project will focus on such interactions between powdery mildews, important pathogens of many crops and wild plants, and their common fungal parasites (Ampelomyces spp.) that have already been utilised as
biocontrol agents in crop protection. Genetic and genomic tools will be used to deter ....My enemy’s enemy is my friend: The genetics of major plant pathogen killers. Fungi are devastating agents of crop diseases. These plant pathogens, in turn, are often parasitized by other fungi in the field. The project will focus on such interactions between powdery mildews, important pathogens of many crops and wild plants, and their common fungal parasites (Ampelomyces spp.) that have already been utilised as
biocontrol agents in crop protection. Genetic and genomic tools will be used to determine if these parasites evolved by switching host from plants to plant pathogens. The project has the potential to make a ground-breaking discovery in this field, and also establish the starting point for new innovative methods to protect a wide diversity
of crops using these fungi or specific compounds derived from them.Read moreRead less
YhcB, a crucial player in the control of bacterial cell envelope biogenesis. All life depends on a cell envelope to enclose the chemical reactions that make life possible. But how do cell envelopes grow? How each component of the cell envelope is incorporated into the envelope at the right amount and in the right time to prevent cell death, has been a longstanding question in bacteriology. Using a unique combination of high through put genetic screens and biochemical approaches, this project wil ....YhcB, a crucial player in the control of bacterial cell envelope biogenesis. All life depends on a cell envelope to enclose the chemical reactions that make life possible. But how do cell envelopes grow? How each component of the cell envelope is incorporated into the envelope at the right amount and in the right time to prevent cell death, has been a longstanding question in bacteriology. Using a unique combination of high through put genetic screens and biochemical approaches, this project will characterise a key regulator of cell envelope growth in Gram-negative bacteria. Knowledge arising from this research will provide insight into a fundamental process in bacteria, will develop new technology to probe protein interactions, and will provide novel avenues to solve infection in plants, humans and animals.Read moreRead less
