Summary
Uncovering the roles of key ribonucleases critical for post-transcriptional control of chloroplast gene expression. Higher plant chloroplasts harbour key biological processes that are essential to life on earth. Deciphering the roles of important plastid-targeted ribonucleases, central to post-transcriptional ribonucleic acid (RNA) processing events, is crucial to elucidate the genetic elements required to engineer chloroplast metabolic pathways to enhance productive crop yields.

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

Summary
Traffic on DNA: interplay between RNA polymerases and DNA-bound proteins. The DNA inside the cell is not just a repository of information, but is an active player in how that information is used. Proteins bind to defined locations on the DNA to control which genes are active, and genes are expressed by RNA polymerases that track along the DNA. Collisions between RNA polymerases and DNA-bound proteins can remove the proteins or block the polymerase. How can these essential processes safely coexis ....Traffic on DNA: interplay between RNA polymerases and DNA-bound proteins. The DNA inside the cell is not just a repository of information, but is an active player in how that information is used. Proteins bind to defined locations on the DNA to control which genes are active, and genes are expressed by RNA polymerases that track along the DNA. Collisions between RNA polymerases and DNA-bound proteins can remove the proteins or block the polymerase. How can these essential processes safely coexist on the DNA? The project aims to integrate systematic experiments using well-defined genetic components and mathematical modelling to understand the 'design' features of DNA and proteins that minimise these traffic problems. A better understanding could inform new strategies for manipulation of gene expression.Read moreRead less

Summary
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.

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

These elements are now ripe for discovery due to recent advances in epigenomics allowing for rapid identification. This proposal aims to discover heat-associated elements in waxy bluebells, which inhabit Australia’s vulnerable high country. Expected outcomes include new insights on gene regulatory mechanisms in native plants; the generation of resources for genetic conservation, and catalysing further molecular research into Australian flora. This should provide significant benefits by revealing genome regulation in native plants, thereby improving the ability to predict the impacts of climate change.Read moreRead less

Summary
The Life And Death Of Plant Genes. My recent work has demonstrated that in contrast to animal genes, many plant genes show presence/absence variation within a species, with associated trait variation. In this project, I will explore models of gene birth and death by comparing genomes of Brassicaceae, including the model Arabidopsis and Brassica crop species. By comparing many genomes I will learn how new genes were born. I will build models that predict the likelihood of gene loss based on a gen ....The Life And Death Of Plant Genes.

In this project, I will explore models of gene birth and death by comparing genomes of Brassicaceae, including the model Arabidopsis and Brassica crop species. By comparing many genomes I will learn how new genes were born. I will build models that predict the likelihood of gene loss based on a gene’s physical environment, function, and expression. The project will build on our understanding of plant genetic diversity. Expected outcomes of this research include the identification of key genomic elements in gene birth and loss and support strategies to improve plant cultivars.Read moreRead less

Although ribosomes have been historically thought of as uniform entities, recent evidence suggests that their composition might be regulated. Elevating the expression of a target protein without affecting mRNA levels is expected to benefit other disciplines, including biotechnology (e.g. recombinant protein expression), biomedicine (e.g. treatment of a human disease by suppression or enhancement of the levels of key disease-related proteins) and synthetic biology.Read moreRead less
