Summary
Unravelling the structural evolution of centipede toxins. The project intends to improve understanding of venom evolution in centipedes, and uncover new families of peptides with potential application in the agrochemical and pharmaceutical sectors. Venoms have emerged as a rich source of pharmacological tools with potential for development into therapeutics and bioinsecticides. However, venoms-based discovery has been limited by the narrow taxonomical range studied, and many groups of venomous a ....Unravelling the structural evolution of centipede toxins. The project intends to improve understanding of venom evolution in centipedes, and uncover new families of peptides with potential application in the agrochemical and pharmaceutical sectors. Venoms have emerged as a rich source of pharmacological tools with potential for development into therapeutics and bioinsecticides. However, venoms-based discovery has been limited by the narrow taxonomical range studied, and many groups of venomous animals remain overlooked. One such group is centipedes, whose venoms contain diverse novel toxins. This project aims to provide an insight into centipede toxin evolution, and establish a structure-based approach to understanding their evolution and structural diversification. The outcomes may contribute to our understanding of protein evolution and support the development of new products.Read moreRead less

First, it will enhance Australia's research capacity in the fields of organelle genomics and evolutionary biology. Second, it will yield highly skilled young researchers: a postdoctoral fellow (Shao), a PhD student and two BSc Honours students. Third, it will generate new knowledge about genome recombination in animal mitochondria. Recombination is a fundamental, yet poorly understood issue in mitochondrial genomics and evolutionary biology. Knowledge from this project will also improve our understanding of other important issues that are associated with animal mitochondria; like the mechanisms of mitochondrial disease and ageing, and the evolution of modern humans and other animals.Read moreRead less
Monotreme immune system provides insights into their evolutionary relationships. Genes of immunological importance will be cloned and characterised from the short-beaked echidna with the purpose of investigating the immune system in monotremes, gaining insights into the timing and order of evolutionary separation of the three extant mammalian groups:- the Prototherians (monotremes), the Metatherians (marsupials) and Eutherians (placentals), increasing understanding of the evolution of the verteb ....Monotreme immune system provides insights into their evolutionary relationships.

Movement patterns and habitat utilisation of the endangered eastern freshwater cod, Maccullochella ikei Rowland. The project aims to quantify the movement patterns and habitat utilisation of the endangered eastern freshwater cod (Maccullochella ikei) at a larval, juvenile, adult and historical level. Most previous studies regarding the life-history of fish species have failed to adopt this holistic approach, with management often based on fragmented information. The project will also provide an ....Movement patterns and habitat utilisation of the endangered eastern freshwater cod, Maccullochella ikei Rowland. The project aims to quantify the movement patterns and habitat utilisation of the endangered eastern freshwater cod (Maccullochella ikei) at a larval, juvenile, adult and historical level. Most previous studies regarding the life-history of fish species have failed to adopt this holistic approach, with management often based on fragmented information. The project will also provide an insight into the biology of one of the most poorly understood coastal stream fishes of eastern-Australia and assist in ensuring the conservation of this endangered species, and offer a framework from which future studies into the life history of freshwater fish species worldwide can be based.Read moreRead less
Conservation genetics of the Endangered Oxleyan Pygmy Perch Nannoperca oxleyana. The aim of this study is to determine how isolation of populations of the endangered Oxleyan Pygmy Perch Nannoperca Oxleyana affects their genetic composition. The significance of the study is that it will enhance our ability to conserve the species, and enhance our understanding of the genetics of isolated populations of freshwater fish generally.

The primary benefits are contribution to Australia's knowledge base and raising the profile of functional genomics in Australia, with the research priority of Frontier Technologies for Building and Transforming Australian Industries and priority goals in Breakthrough Science and Frontier Technologies. This project focuses on important biological questions surrounding gene regulation and sex chromosome evolution. International attention has already resulted in genome characterization of Australian icons (wallaby, Tasmanian devil and platypus), more research on these, and other Australian animals, will further highlight the importance of Australian fauna and impact positively on our scientific profile.Read moreRead less
Origin and evolution of genes on the human X chromosome. Two groups of functionally related genes are found on the human X chromosome in disproportionately high numbers. I will test whether an uneven distribution of genes is common in mammalian genomes, or whether the human X is special. I will test hypotheses of how the gene groups arose on the human X by comparing their location and expression patterns in other mammals, and other vertebrates. It will then be clear whether the ancestral autosom ....Origin and evolution of genes on the human X chromosome. Two groups of functionally related genes are found on the human X chromosome in disproportionately high numbers. I will test whether an uneven distribution of genes is common in mammalian genomes, or whether the human X is special. I will test hypotheses of how the gene groups arose on the human X by comparing their location and expression patterns in other mammals, and other vertebrates. It will then be clear whether the ancestral autosome was ?chosen?, whether it ?selfishly? accumulated these genes, or whether the function of genes changed in response to selective pressures.Read moreRead less
Small is beautiful: Did gene-rich regions of mammal chromosomes evolve from microchromosomes? Most birds and reptile genomes feature many tiny microchromosomes. These are not junk, as previously thought, but contain most of the genes. Mammals lack microchromosomes, but contain gene-rich regions with similar attributes. We suggest that microchromosomes originated by genome duplication, and evolved into the gene-rich regions of mammalian chromosomes. We will test this hypothesis by comparing seque ....Small is beautiful: Did gene-rich regions of mammal chromosomes evolve from microchromosomes? Most birds and reptile genomes feature many tiny microchromosomes. These are not junk, as previously thought, but contain most of the genes. Mammals lack microchromosomes, but contain gene-rich regions with similar attributes. We suggest that microchromosomes originated by genome duplication, and evolved into the gene-rich regions of mammalian chromosomes. We will test this hypothesis by comparing sequences and genes in microchromosomes of birds, reptiles and monotremes. This will clarify the origin and evolution of the ?microgenome?, establish its suitability as a model for vertebrate genome organisation, and demonstrate whether microchromosomes are the ancestors of the gene-rich regions of mammalian chromosomes.Read moreRead less
