In this Australian-led Kangaroo Genome Project, we will map and characterize the tammar wallaby genome at the molecular level. Marsupial genomes are uniquely valuable because they provide comparisons that reveal new human genes, regulatory sequences and marsupial-specific genes. These will deliver new products and information useful for medicine, industry, agriculture and conservation. We will construct integrated genetic and physical maps of the genome, clone the whole genome as large inserts in BAC vectors, and build a "golden path" with minimal overlap. We will construct libraries of expressed genes from tammar tissues and array them for use in analysing gene expression.Read moreRead less
Recombination of mitochondrial genomes: what can we learn from chigger mites? This project will bring three benefits to Australia. 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 ....Recombination of mitochondrial genomes: what can we learn from chigger mites? This project will bring three benefits to Australia. 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
New models for the role of chromatin in controlling inducible gene expression. This proposal aims to test novel models of how packaging of DNA in the nucleus plays a fundamental role in gene expression. Understanding these concepts is important in the context of successful gene therapy where major hurdles need to be overcome. This work also has implications for somatic cell therapy since it is important to understand how genes are expressed in order to successfully reprogram cells. Both of these ....New models for the role of chromatin in controlling inducible gene expression. This proposal aims to test novel models of how packaging of DNA in the nucleus plays a fundamental role in gene expression. Understanding these concepts is important in the context of successful gene therapy where major hurdles need to be overcome. This work also has implications for somatic cell therapy since it is important to understand how genes are expressed in order to successfully reprogram cells. Both of these areas are important to the Biotechnology industry. Answering questions about higher order chromatin structure in gene transcription will provide cutting edge, innovative knowledge that will have international significance. Read moreRead less
Chromatin structure and pervasive transcription. This project aims to understand mechanisms that repress pervasive transcription and to identify chromatin characteristics that repress transcription initiation outside the promoter regions. Chromatin characteristics, such as position, occupancy and turnover-rate of nucleosomes, establish an elaborate genomic indexing mechanism, which defines functional units in the genome. Defects in this process increase pervasive transcription, toxic accumulatio ....Chromatin structure and pervasive transcription. This project aims to understand mechanisms that repress pervasive transcription and to identify chromatin characteristics that repress transcription initiation outside the promoter regions. Chromatin characteristics, such as position, occupancy and turnover-rate of nucleosomes, establish an elaborate genomic indexing mechanism, which defines functional units in the genome. Defects in this process increase pervasive transcription, toxic accumulation of non-coding transcripts and genomic instability. This work aims to understand eukaryotic genome organisation and may have long-term therapeutic implications for cancer and ageing-related diseases.Read moreRead less

Summary
Characterisation of nuclear-localised microRNAs. This project is focused on a set of very small RNA molecules, called microRNAs that regulate genes activity. This project will likely redefine our understanding of microRNA-based gene regulation in complex animals, and may result in new RNA therapeutics for previously untreatable illnesses.
Development of molecular markers for resistance to blackleg disease (Leptosphaeria maculans) in canola. Canola (Brassica napus) is a valuable oil seed crop grown in many parts of the world and contributes annually $A450 million to the Australian economy.

Canola (Brassica napus) is a valuable oil seed crop grown in many parts of the world and contributes annually $A450 million to the Australian economy. The overall aim of this project is to develop molecular markers for blackleg resistance using Australian germplasm along with evaluation in Australian disease nurseries which are regarded worlwide to develop the highest levels of disease pressure. Once molecular marker systems are developed and evaluated, they will be applied to facilitate the selection of Nugrain's (Industry Partner) canola breeding programs. Any molecular markers and QTL developed for Australian cultivars would find commercial application in breeding programmes.Read moreRead less

Elucidating a novel mechanism for coping with harmful mutations. This project aims to improve our understanding of the complex regulatory mechanisms that increase genetic and phenotypic robustness. Survival of organisms depends on their ability to cope with genetic variation. A novel process of genetic compensation has recently been identified, producing a normal phenotype in a homozygous mutant, that would be expected to have deleterious effects.

This project aims to improve our understanding of the complex regulatory mechanisms that increase genetic and phenotypic robustness. Survival of organisms depends on their ability to cope with genetic variation. A novel process of genetic compensation has recently been identified, producing a normal phenotype in a homozygous mutant, that would be expected to have deleterious effects. This project will reveal how compensation is achieved by examining the molecular pathways that are activated following genetic mutation. This project is expected to strengthen Australian reputation in evolutionary genetics, and in turn enhance our understanding of how organisms adapt to changing environments.Read moreRead less

Summary
Identifying parent-of-origin effects and their impact on complex traits. This project aims to systematically identify genetic variants whose effects depend on whether they were inherited from the mother or the father, and to assess their impact on complex human traits. Most gene mapping studies to date assume that the effects of genetic variants are equal regardless of the parent of origin, thus have not explored this source of genetic variation. However, animal studies indicate that parent-of-o ....Identifying parent-of-origin effects and their impact on complex traits. This project aims to systematically identify genetic variants whose effects depend on whether they were inherited from the mother or the father, and to assess their impact on complex human traits. Most gene mapping studies to date assume that the effects of genetic variants are equal regardless of the parent of origin, thus have not explored this source of genetic variation. However, animal studies indicate that parent-of-origin specific effects (POEs) are important contributors to variability of developmental and behavioural traits. Leveraging genetic and epigenetic data from some of the world’s largest cohorts, this project will improve our understanding of POEs on complex human traits related to early development, growth and behaviour.Read moreRead less
