Cellular determinants of retrotransposition. This project aims to understand the processes that control retrotransposition in a genome. Transposable elements make up more than 50% of human genomes. The accumulation of retrotransposons through millions of years of evolution has shaped the genomes of all eukaryotic organisms, including humans. Researchers have elucidated mechanisms the host uses to defend the genome against insertional mutagenesis by retrotransposons, but the cellular machinery an ....Cellular determinants of retrotransposition. This project aims to understand the processes that control retrotransposition in a genome. Transposable elements make up more than 50% of human genomes. The accumulation of retrotransposons through millions of years of evolution has shaped the genomes of all eukaryotic organisms, including humans. Researchers have elucidated mechanisms the host uses to defend the genome against insertional mutagenesis by retrotransposons, but the cellular machinery and genomic environments needed for retrotransposition are undefined. This project aims to use models to uncover the mechanisms that control retrotransposition. This is expected to reveal more about human origins.Read moreRead less
Deciphering the regulatory principles of metazoan development. This proposal aims to elucidate how regulatory elements in the genome, known as enhancers, determine the identity and function of animal tissues. Currently, it is believed that enhancers cannot be traced across evolutionarily distant animals. The project uses novel concepts, computational and molecular approaches to identify deeply conserved enhancers. It further dissects the mechanism of function by proteomics and high-throughput ge ....Deciphering the regulatory principles of metazoan development. This proposal aims to elucidate how regulatory elements in the genome, known as enhancers, determine the identity and function of animal tissues. Currently, it is believed that enhancers cannot be traced across evolutionarily distant animals. The project uses novel concepts, computational and molecular approaches to identify deeply conserved enhancers. It further dissects the mechanism of function by proteomics and high-throughput genomics. The expected outcomes will overturn our current view on enhancer evolution and reposition our understanding of how enhancers are functionally encoded in the genome. The work is an important contribution to understanding cellular complexity and species evolution with wide-ranging impact in genetics.Read moreRead less
Visualising genetic mosaicism during development. Genetic diversity is the variation in DNA sequence among individuals. We now know that there are also differences in the DNA sequences of cells within the same individual, known as genetic mosaicism. The aims of this proposal are 1) to develop a system to visualise genetic mosaicism 2) arising during embryonic development and 3) in the brain, driven by mobile DNA activity. The expected outcome of this proposal is an unprecedented understanding of ....Visualising genetic mosaicism during development. Genetic diversity is the variation in DNA sequence among individuals.

The expected outcome of this proposal is an unprecedented understanding of the scope and consequences of mobile DNA-driven mosaicism. This work will have significant impacts in developmental genetics and neurogenetics, and has the benefit of introducing an innovative experimental system with the potential to spark international scientific collaboration and recognition.Read moreRead less

Summary
Evolution of genome architecture. The project aims to understand how changes to genome architecture over evolutionary time are linked to the diversity of animal morphology. Our genome sequence is arranged into higher order structures that enable coordinated gene expression. The appropriate expression of genes in time and space is necessary to produce the multitude of cell types that make up a multicellular organism. Yet, to date, genome topology is poorly explored, especially between species. Th ....Evolution of genome architecture. The project aims to understand how changes to genome architecture over evolutionary time are linked to the diversity of animal morphology. Our genome sequence is arranged into higher order structures that enable coordinated gene expression. The appropriate expression of genes in time and space is necessary to produce the multitude of cell types that make up a multicellular organism. Yet, to date, genome topology is poorly explored, especially between species. The project involves comparisons of the 3D structure of genomes in divergent species. These findings are expected to inform the underlying principles of gene regulation in animals and species evolution.Read moreRead less
Mapping recombination blocks in Brassica. DNA technology provides new ways to study genomes. Understanding how the genome behaves during plant breeding will help design strategies for the breeding and selection of improved crop plants.
Evolution and function of fragmented animal mitochondrial genomes. This project will reveal why animal mitochondrial genomes are in pieces, and how fragmented mitochondrial genomes evolve and function. This project will discover whether or not fragmented mitochondrial genomes have functional advantages. Knowledge generated from this project will lead to new approaches to mitochondrial genetic diseases in humans.
The MYB gene as a model for global transcriptional regulation: stopping, starting and looping. This project will study how transcriptional elongation controls the MYB gene, a key regulator of normal and cancerous growth and regulation.

This project will study how transcriptional elongation controls the MYB gene, a key regulator of normal and cancerous growth and regulation. There are three major benefits that are likely to flow from the proposed research It will strengthen research in new and important areas of transcriptional regulation, by building research capacity in Australia in the area of gene expression, particularly with respect to transcriptional elongation and long-range regulation. It will highlight a new approach to the therapeutic targeting of MYB in cancer: data generated from this research may enable us to target MYB expression in a range of cancers including breast cancer by inhibiting transcriptional elongation. And it will provide training in advanced molecular biology to postdoctoral scientists and students.Read moreRead less
Towards a new understanding of the reproductive system. The proposed analysis of the reproductive system will provide important new knowledge of gene regulation driving organ development. The insights and technologies developed in this program will be widely applicable in biotechnological and pharmacogenomic research in Australia and worldwide, and assert Australia's leadership in this area of research.
Co-ordinated Action of ATM and DNA-PK in DNA damage recognition. The aim of this project is to investigate the mechanism of repair of double straind breaks in DNA sustained after radiation damage. Specifically we will focus on two proteins ATM (mutated in the genetic disorder ataxia-telangiectasia) and DNA-PK mutated in scid mice. There two proteins recognize double straind breaks in DNA and signal this damage to the DNA repair machinery of the cell and to cell cycle checkpoints. The emphasis ....Co-ordinated Action of ATM and DNA-PK in DNA damage recognition.

There two proteins recognize double straind breaks in DNA and signal this damage to the DNA repair machinery of the cell and to cell cycle checkpoints. The emphasis here will be in the relationship between the two proteins in co-ordinating the repair of breaks in DNA. This information will be important in understanding mechanisms for maintaining the integrity of the genome.Read moreRead less

Gene content varies between individual varieties. The project aims to apply novel genomic tools to identify and characterise the fixed and variable gene content in the important crop canola and use this to understand genome evolution as well as develop tools to accelerate canola breeding. The project team have developed and used a high-resolution genotyping approach to demonstrate that gene conversions, short recombination events which lead to the non-reciprocal exchange of genomic regions during meiosis, are abundant in crop genomes. The project aims to develop methods and resources to characterise gene conversion in canola and establish a basis for gene conversion based crop improvement.Read moreRead less
