Sugar transporters in coral symbiosis and origin of parasitism. We aim to identify how symbiotic algae feed sugar to their coral hosts. Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef. We also aim to explore whether coral/algal coopera ....Sugar transporters in coral symbiosis and origin of parasitism. We aim to identify how symbiotic algae feed sugar to their coral hosts. Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef. We also aim to explore whether coral/algal cooperation paved the way for the origin of parasitism. The second key outcome will be to identify the precise molecular mechanism that allowed parasitism to arise. This will benefit us through understanding the origins of important diseases such as human malaria and related infections of livestock and wildlife.

Revealing the determinants of viral emergence and evolution in fish. Viral diseases pose an ongoing threat to Australian aquaculture. The devastating impact of emerging viruses makes it imperative to understand the factors that allow them to evolve and infect new hosts. We will address these key issues by revealing the diversity, abundance and evolution of viruses in fish sampled along the Australian east coast. The data generated will reveal the untapped biodiversity of fish viruses, the freque ....Revealing the determinants of viral emergence and evolution in fish. Viral diseases pose an ongoing threat to Australian aquaculture. The devastating impact of emerging viruses makes it imperative to understand the factors that allow them to evolve and infect new hosts. We will address these key issues by revealing the diversity, abundance and evolution of viruses in fish sampled along the Australian east coast. The data generated will reveal the untapped biodiversity of fish viruses, the frequency which they jump species boundaries and the determinants of this process, and how they are impacted by host ecology, including whether fish viruses follow a latitudinal gradient in diversity. The data generated will transform our understanding of fish viruses and identify those most likely to impact aquaculture.Read moreRead less
The effect of methylation and phosphorylation on ribosome function. This project aims to discover how cells regulate ribosome function and selectivity, by modifying their ribosomal proteins. This affects protein synthesis, a process which is central to the growth of all living things. Expected outcomes include new knowledge on the regulation of protein synthesis, improved techniques for the study of this process and an enhanced capacity for international collaboration.

This affects protein synthesis, a process which is central to the growth of all living things. Expected outcomes include new knowledge on the regulation of protein synthesis, improved techniques for the study of this process and an enhanced capacity for international collaboration. New avenues for the artificial regulation of the ribosome may also emerge, relevant to synthetic biology and the engineering of industrial yeasts. The project should provide significant new findings for the research community, generate research citations and contribute to a highly skilled workforce by the training of staff and students.Read moreRead less
The macrophage nucleus - its form and function during migration in vivo. As cells migrate through tissues, they encounter complex, 3-dimensional environments that provide cues to guide them and present obstacles in their path. This project focuses on macrophages, a large immune cell capable of both amoeboid and mesenchymal modes of migration. The nucleus is the largest organelle and its bulk and stiffness must be managed as migrating cells travel through constrictions. The project uses specialis ....The macrophage nucleus - its form and function during migration in vivo. As cells migrate through tissues, they encounter complex, 3-dimensional environments that provide cues to guide them and present obstacles in their path. This project focuses on macrophages, a large immune cell capable of both amoeboid and mesenchymal modes of migration. The nucleus is the largest organelle and its bulk and stiffness must be managed as migrating cells travel through constrictions. The project uses specialised high-end microscopy and genetic methods to examine how the nucleus of migrating zebrafish macrophages deforms, repositions and is restructured during migration in living tissues, and how this influences macrophage locomotion. The goal is to provide fundamental insights into the cell biology of macrophage migration.Read moreRead less
How do protein quality control mechanisms maintain neuronal ageing? This project aims to interrogate how mechanisms of protein quality control act in the brain - an organ that is particularly vulnerable to a high load of misfolded protein - to maintain normal physiology during ageing.

This project aims to interrogate how mechanisms of protein quality control act in the brain - an organ that is particularly vulnerable to a high load of misfolded protein - to maintain normal physiology during ageing. This project expects to make advances in cellular biochemistry and neuroscience, using an innovative proximity labelling approach to identify quality control regulators in neurons that specifically engage with misfolded proteins during ageing, within the nervous system of a living animal. Expected outcomes of this project will generate new knowledge of brain physiology and ageing relevant to all animals. This should provide significant benefits, such as a greater understanding of long-term brain functions including memory.Read moreRead less
Cracking the code of snails to elucidate parasite disease transmission. In Australia, a disease caused by liver flukes causes major economic losses to livestock production. The role of Australian pond snails as intermediate hosts for this parasite is poorly understood. This project aims to explore the phylogeography, biology and genomics of these snails. It expects to create novel molecular resources for important snail species and verify their roles as key vectors of flatworm parasites.

The role of Australian pond snails as intermediate hosts for this parasite is poorly understood. This project aims to explore the phylogeography, biology and genomics of these snails. It expects to create novel molecular resources for important snail species and verify their roles as key vectors of flatworm parasites. The curation of genomic and transcriptomic data sets, and elucidation of snail–parasite interactions will underpin the development of environmental diagnostic tests and deliver a new generation of intervention strategies to reduce the burden of liver fluke disease through the control of their snail intermediate hosts.Read moreRead less
