How does an essential histone variant effect changes in gene expression? The mechanisms that determine how genes are switched on and off in different tissues and at different times are not clearly known. It is well established that gene expression patterns are determined in part by the molecular signals transmitted by variation in the proteins that package eukaryotic DNA. Our aim is to understand new aspects of these mechanisms that revolve around how our DNA is packaged. This foundational knowl ....How does an essential histone variant effect changes in gene expression? The mechanisms that determine how genes are switched on and off in different tissues and at different times are not clearly known. It is well established that gene expression patterns are determined in part by the molecular signals transmitted by variation in the proteins that package eukaryotic DNA. Our aim is to understand new aspects of these mechanisms that revolve around how our DNA is packaged. This foundational knowledge will deepen our understanding of gene regulation in all complex organisms and will inform future efforts to rationally modulate gene expression patterns in agriculture, research and other important areas.Read moreRead less
National Macadamia Conservation Program. Macadamia is a national icon, and the only indigenous Australian plant food crop to be commercialised. However, it is vulnerable to extinction in the wild, needing conservation action. University, government, industry and community sectors will work together applying cutting edge research methodologies to produce a systematic conservation and recovery plan for Macadamia. This requires: Habitat modelling to predict past, contemporary and potential distribu ....National Macadamia Conservation Program. Macadamia is a national icon, and the only indigenous Australian plant food crop to be commercialised. However, it is vulnerable to extinction in the wild, needing conservation action. University, government, industry and community sectors will work together applying cutting edge research methodologies to produce a systematic conservation and recovery plan for Macadamia. This requires: Habitat modelling to predict past, contemporary and potential distributions for advising resource discovery and rehabilitation; Genetic variation modelling to assess quality and distinctness of native genetic resources and potential for rehabilitation by natural colonisation; and Developing a unifying statistical framework to support this work.Read moreRead less
Uncovering an evolutionary advanced mechanism of gene expression control. This project aims to uncover a new mechanism that activates gene expression in mammals, which involves unexpected connections between the core components of chromosomes and essential enzymatic machines required for the expression of genes. This project will generate new knowledge on the poorly understood process of how the extensive genomic information of multicellular organisms is selectively chosen to enable the expressi ....Uncovering an evolutionary advanced mechanism of gene expression control. This project aims to uncover a new mechanism that activates gene expression in mammals, which involves unexpected connections between the core components of chromosomes and essential enzymatic machines required for the expression of genes. This project will generate new knowledge on the poorly understood process of how the extensive genomic information of multicellular organisms is selectively chosen to enable the expression of only the required subset of genes. This will revolutionise our understanding of the mechanisms of gene control thereby shaping the field in the future. Significantly, this will allow new ways to manipulate gene expression that will impact biotechnology by providing new efficient ways to produce proteins or RNA. Read moreRead less
Nuclear RNA surveillance and its connection to splicing quality control. Due to the error-prone nature of RNA splicing, elaborate quality control processes ensure that only correctly spliced transcripts can leave the nucleus. It has long been known that incorrectly spliced mRNA transcripts are degraded by the nuclear RNA surveillance machinery, but how the RNA quality control machinery is connected to nuclear RNA surveillance is not known. This proposal aims to uncover the connection between the ....Nuclear RNA surveillance and its connection to splicing quality control. Due to the error-prone nature of RNA splicing, elaborate quality control processes ensure that only correctly spliced transcripts can leave the nucleus. It has long been known that incorrectly spliced mRNA transcripts are degraded by the nuclear RNA surveillance machinery, but how the RNA quality control machinery is connected to nuclear RNA surveillance is not known. This proposal aims to uncover the connection between these two important processes and will fill a significant gap in our understanding of how splicing quality control and nuclear RNA surveillance work. The project will also identify sequence features that trigger abortive splicing reactions and will thus help to improve the design of synthetic mRNAs.Read moreRead less
Membrane attack complex/perforin-like proteins in developmental and neurobiology. This project will aim to use the fruit fly as a model system to understand how members of the perforin-like superfamily, a family of proteins more usually associated with mammalian immunity, function in embryonic and neural development. These data will eventually provide central insight into human diseases such as cancer and autism spectrum disorder.
Transcription factors find their targets by reading the epigenetic code. This project aims to elucidate how transcription factors, proteins that regulate gene expression, find their target genes. The hypothesis is that non-DNA binding domains play an essential role in this process. This project expects to transform our understanding of transcription factor families, and how factors in families with the same DNA-binding domain manage to regulate different genes. Expected outcomes of this project ....Transcription factors find their targets by reading the epigenetic code. This project aims to elucidate how transcription factors, proteins that regulate gene expression, find their target genes. The hypothesis is that non-DNA binding domains play an essential role in this process. This project expects to transform our understanding of transcription factor families, and how factors in families with the same DNA-binding domain manage to regulate different genes. Expected outcomes of this project include revealing how accessory proteins help transcription factors identify their targets in the genome by reading epigenetic marks. This should provide significant benefits including improved design of artificial transcription factors to up- or down-regulate specific genes in research and agriculture.Read moreRead less

Polycomb Group Proteins - Shaping Chromatin Architecture to Silence Genes . This project aims to address the fundamental question of how genes are switched off by studying a group of molecular off-switches, the polycomb group proteins.

The project is expected to generate new knowledge in the area of gene regulation and epigenetics by combining innovative methods of structural biology and cell biology in an interdisciplinary way. The expected outcomes include a more complete picture of the molecular mechanisms that regulate gene expression and the development of novel methods to image the genome. This should provide significant benefits, such as facilitated development of gene editing tools and regulatory circuits for synthetic biology, as well as novel capabilities to image the genome at high resolution Read moreRead less
Development of genetic technology for rodent population suppression. Vertebrate pests cost Australia over $1 billion each year in agricultural losses and environmental damage and novel strategies are urgently required to tackle this massive challenge. Newly proposed “gene drives”, which might rapidly spread through populations, have enormous potential for the sustained management and even eradication of pests.

Vertebrate pests cost Australia over $1 billion each year in agricultural losses and environmental damage and novel strategies are urgently required to tackle this massive challenge. Newly proposed “gene drives”, which might rapidly spread through populations, have enormous potential for the sustained management and even eradication of pests. Through innovative application of cutting-edge genome editing approaches, this proposal aims to develop gene drive technology in mice as a prototypical vertebrate pest species. We will also develop cutting-edge mathematical models of rodent gene drives to identify crucial parameters for efficacious employment and investigate potential for impact on non-target populations.Read moreRead less
