Disease caused by the bacterium Clostridium difficile are a significant food production animal and public health problem in many countries. Specific animal and human public health resources have been allocated in many countries in efforts to mitigate the growing epidemics. The study proposed in this application presents a significant opportunity to learn about the virulence factors of animal strains of this bacterium about which very little is known. This project will lead to rationally designed preventative and treatment strategies that apply to both animals and humans, thereby impeding epidemics caused by C. difficile in Australia.Read moreRead less
Pathogenesis, regulation and genomics of the ovine footrot pathogen, Dichelobacter nodosus. Footrot is one of the most economically significant diseases of sheep in Australia. The aim of this project is to develop a detailed understanding of how the bacterium that causes this infection is able to infect the sheep hoof and result in clinical disease. The complete sequence of the genome of the causative bacterium will be determined, enabling us to deduce its genetic potential.

The aim of this project is to develop a detailed understanding of how the bacterium that causes this infection is able to infect the sheep hoof and result in clinical disease. The complete sequence of the genome of the causative bacterium will be determined, enabling us to deduce its genetic potential. The completed project will significantly advance fundamental knowledge of the disease process and will lead to the development of improved methods for the control of the disease, with concomitant cost savings to Australian primary industry.Read moreRead less

Summary
Australian Microbial Genomics Research Network. The Australian Microbial Genomics Research Network aims to bring together Australian scientists with complementary expertise in microbial genomics within two ARC Centres, a Ramaciotti Centre and four institutions across three states. This initiative will involve the strategy and planning of the proposed Network.
ARC Centre for Structural & Functional Microbial Genomics. Australian Primary Industry will benefit from a team of experts in microbial genetics, bioinformatics and protein structure and function undertaking integrated studies on microbial genomics and phenomics that are focused on fundamental biological processes and host/pathogen interactions. Whole genome expression and protein profiling will be used to characterise genes whose expression is altered in the infected host and to analyse genes i ....ARC Centre for Structural & Functional Microbial Genomics. Australian Primary Industry will benefit from a team of experts in microbial genetics, bioinformatics and protein structure and function undertaking integrated studies on microbial genomics and phenomics that are focused on fundamental biological processes and host/pathogen interactions. Whole genome expression and protein profiling will be used to characterise genes whose expression is altered in the infected host and to analyse genes involved in the control of key cellular processes. The Centre will also determine the shapes of key molecules and their interactions. Practical outcomes will include new veterinary vaccines and the identification of novel antimicrobial targets.Read moreRead less
Further Genetic and Molecular studies of an Important Prokaryotic Regulator Protein TyrR. Genomes encode many functions whose expression varies dramatically depending on particular cellular environments. Special proteins called Regulator Proteins act as sensors to detect subtle changes in the environment and, in response, to influence the expression of certain genes either dampening them down or stimulating their activity. We are working with the TyrR regulator protein of the simple bacterium E ....Further Genetic and Molecular studies of an Important Prokaryotic Regulator Protein TyrR. Genomes encode many functions whose expression varies dramatically depending on particular cellular environments. Special proteins called Regulator Proteins act as sensors to detect subtle changes in the environment and, in response, to influence the expression of certain genes either dampening them down or stimulating their activity. We are working with the TyrR regulator protein of the simple bacterium Escherichia coli to elucidate the molecular strategies used in these controls. Because this protein controls the expression of a number of genes with diverse functions, evolution has selected equally diverse mechanisms to achieve appropriate transcriptional responses. The detailed knowledge of the E.coli genome and of the various genes regulated by TyrR make it an excellent system for such fundamental studies.Read moreRead less

Summary
Genes, reproduction and inheritance in a microbe. The project aims to particularly explore sexual gene inheritance in Plasmodium, a representative of a large group of human and animal parasites. Plasmodium must have a sexual exchange of genes in the mosquito for the transfer of disease to a new host. This project will investigate the fate and behaviour of Plasmodium genes during reproduction; the differing chromosome states resulting from sexual genetic processes and the asymmetrical inheritance ....Genes, reproduction and inheritance in a microbe. The project aims to particularly explore sexual gene inheritance in Plasmodium, a representative of a large group of human and animal parasites. Plasmodium must have a sexual exchange of genes in the mosquito for the transfer of disease to a new host. This project will investigate the fate and behaviour of Plasmodium genes during reproduction; the differing chromosome states resulting from sexual genetic processes and the asymmetrical inheritance of some Plasmodium genes. The project is expected to advance Australia’s ability to understand the reproduction and survival of these parasites in their mosquito vector and develop cutting-edge genetic tools that will advance the microbial genetics discipline globally. This may ultimately lead to biotechnology and biomedical outcomes.Read moreRead less
Experimental co-evolution of Yeast and E. coli. This project aims to measure the rates and genetic mechanisms of adaptation for individual species within a microbial community. Expected outcomes of this interdisciplinary project include the first genomic and phenotypic dataset of a model microbial community, and novel tools for the analysis of meta-genomic datasets. This project has the potential to transform understanding of microbial adaptation.

The ability of cells to regulate gene expression is key for organism development, adaptation to new environments and evolutionary changes that shape the diversity of life on Earth. This project studies the RNA binding proteins called PUFs which are central for gene expression in diverse organisms. Using cutting-edge new generation systems biology approaches, this project will study how PUF proteins regulate genes to enable metabolic adaptation, differentiation of cell types and the evolution of new gene expression outputs in distinct biological species. The outcomes will include new insights into the regulation and evolution of posttranscriptional gene networks. Read moreRead less
