Using venoms to map critical and evolutionary conserved vulnerabilities. We have developed and applied new functional genomic approaches to study venom evolution. Using CRISPR screening, we find that unrelated venoms act on cells by exploiting the same vulnerabilities. By functionally mapping these vulnerabilities for all venom classes, we can begin to develop universal venom antidotes. Conversely, much of what we know about venom mechanisms comes from a small percentage of the biodiversity with ....Using venoms to map critical and evolutionary conserved vulnerabilities. We have developed and applied new functional genomic approaches to study venom evolution. Using CRISPR screening, we find that unrelated venoms act on cells by exploiting the same vulnerabilities. By functionally mapping these vulnerabilities for all venom classes, we can begin to develop universal venom antidotes. Conversely, much of what we know about venom mechanisms comes from a small percentage of the biodiversity within a venom, and we have developed genomic tools to study the venom “dark matter”. This work will lead to the full molecular characterisation of venom biodiversity, and new venom components will be useful for research or as novel medicines.Read moreRead less
The evolutionary transition from anaerobic to aerobic metabolism. This project aims to find out how life on Earth survived the revolutionary changes when cyanobacteria first released oxygen into the atmosphere. These events led to a transition from anoxic (oxygen-free) to oxic (oxygen-rich) conditions. A comparative genomic view across a series of photosynthetic organisms will be performed at the molecular level with ecological interpretation. Understanding of what metabolic changes occurred in ....The evolutionary transition from anaerobic to aerobic metabolism. This project aims to find out how life on Earth survived the revolutionary changes when cyanobacteria first released oxygen into the atmosphere. These events led to a transition from anoxic (oxygen-free) to oxic (oxygen-rich) conditions. A comparative genomic view across a series of photosynthetic organisms will be performed at the molecular level with ecological interpretation. Understanding of what metabolic changes occurred in response to the shifts in the environment will have wide implications for predicting the evolutionary events that are still occurring today, such as rapidly changing climatic conditions. This fundamental research will enhance Australia's profile in this field.Read moreRead less
Structure and temperature adaptation of chaperonin TF55 from Sulfolobus solfataricus. Our work has future potential both for biotechnology and for medical therapies. The cages formed by chaperonin subunits and their ability to bind to specific targets could lead to their application as nano-vesicles, could facilitate expression of eukaryotic proteins in bacteria and could help to prevent or dissolve protein aggregates. With Australia's ageing population, we can expect an increasing prevalence of ....Structure and temperature adaptation of chaperonin TF55 from Sulfolobus solfataricus. Our work has future potential both for biotechnology and for medical therapies. The cages formed by chaperonin subunits and their ability to bind to specific targets could lead to their application as nano-vesicles, could facilitate expression of eukaryotic proteins in bacteria and could help to prevent or dissolve protein aggregates. With Australia's ageing population, we can expect an increasing prevalence of pathologies such as Alzheimer's and Parkinson's disease and other diseases that arise from protein mis-folding and aggregation, including myopathies and cataracts. A participation of chaperonins has been implicated in these age-related diseases and demands detailed structural and functional investigations.Read moreRead less
Structural reorganization of the hymenopteran mitochondrial genome. This study will be the first detailed investigation of the evolution of mt genome reorganization, and as such it will identify the processes that shape the evolution of a molecule widely used to interpret phylogeny. A description of the processes that lead to mt genome reorganization will have a substantial impact on our understanding in two areas of mt biology; (1) the discovery of new molecular phenomena that impact on the or ....Structural reorganization of the hymenopteran mitochondrial genome. This study will be the first detailed investigation of the evolution of mt genome reorganization, and as such it will identify the processes that shape the evolution of a molecule widely used to interpret phylogeny. A description of the processes that lead to mt genome reorganization will have a substantial impact on our understanding in two areas of mt biology; (1) the discovery of new molecular phenomena that impact on the organization and evolution of this genome, and (2) the interpretation of its phylogenetic content. It will establish our research group as a leader in the field of evolutionary genetics. Training of high quality students, with exposure to international researchers, will be a significant component of this program.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

We aim to discover how and why the key photosynthetic pigments, chlorophylls, are synthesised and used; this will provide new opportunities for breakthroughs in frontier technologies, such as photoelectric cells based on carbon rather than silicon. We aim to understand how novel chlorophylls are used in a variety of important organisms in a range of ecological niches. The results will aid understanding of the effects of global climate change on coral reefs, in open-ocean systems and in other important biological communities.Read moreRead less
Retracing the Early Evolution of Metazoa using Novel Methods and Strategies. Metazoa is one of the best-characterised groups of species in terms of its morphology, fossil record, development, and genetic make-up, but the phylogeny remains obscure because the fossil record is incomplete and because molecular phylogenetic methods have not yet been developed with the complexity of genomic data in mind. We will develop methods and strategies for the analysis of whole genomes, and use them in studies ....Retracing the Early Evolution of Metazoa using Novel Methods and Strategies. Metazoa is one of the best-characterised groups of species in terms of its morphology, fossil record, development, and genetic make-up, but the phylogeny remains obscure because the fossil record is incomplete and because molecular phylogenetic methods have not yet been developed with the complexity of genomic data in mind. We will develop methods and strategies for the analysis of whole genomes, and use them in studies of the mitochondrial genome. We will infer the animal phylogeny, and use it to chart the evolution of animal morphology and development, and the evolution of mitochondrial genetic codes, gene order, and nucleotide content.Read moreRead less
Evolution and ecology of integron gene cassettes: exploring the protein universe. Bacteria rapidly adapt to new conditions by sharing diverse genes via lateral genetic transfer, best illustrated by the spread of antibiotic resistance. This study will characterise mobile genes, discovering new gene families and proteins, and will expand existing knowledge of bacterial evolution.
