Epigenetic and neurobehavioural changes in a new mouse model of foetal alcohol spectrum disorders. Foetal alcohol syndrome involves changes in growth, skull structure, central nervous system defects and intellectual disabilities. This project will use a mouse model to study the underlying causes of this disorder, focussing on brain structure and function, and aim to identify markers that can be used for early diagnosis and treatment.
System-level characterisation of the siphonophore, Indo-Pacific man o' war. The Indo-Pacific man o' war (bluebottle), is a cnidarian from the siphonophore order. These animals frequent Australian beaches in swarms and cause thousands of stings every year. The project proposes to profile the genome, transcriptome, epigenome, and proteome of the bluebottle to gain insight into its life cycle, its behaviour, and toxins. Expected outcomes include the generation of novel information related to bluebo ....System-level characterisation of the siphonophore, Indo-Pacific man o' war. The Indo-Pacific man o' war (bluebottle), is a cnidarian from the siphonophore order. These animals frequent Australian beaches in swarms and cause thousands of stings every year. The project proposes to profile the genome, transcriptome, epigenome, and proteome of the bluebottle to gain insight into its life cycle, its behaviour, and toxins. Expected outcomes include the generation of novel information related to bluebottle gene regulation and its toxin repertoire, which will be highly beneficial for the design of future sting treatment strategies. Given that the bluebottle is a colony made of functionally specialised polyps, this study will also provide significant novel insight into the origins and evolution of animal multicellularity.Read moreRead less

This would provide significant future benefits to all academic, biotechnology, agricultural, veterinary and pharmaceutical applications that involve bacterial genomic analysis.Read moreRead less
The molecular mechanism of action of bacterial epigenetic regulators. This project aims to determine the mechanisms of action of a class of bacterial epigenetic regulators. Many bacteria exhibit phase variable expression of genes (random, high frequency on/off switching of expression), typically due to simple DNA repeats within the gene(s) that encode them. Many bacterial species contain phase variable DNA methyltransferases that regulate epigenetics and control expression of distinct sets of pr ....The molecular mechanism of action of bacterial epigenetic regulators. This project aims to determine the mechanisms of action of a class of bacterial epigenetic regulators. Many bacteria exhibit phase variable expression of genes (random, high frequency on/off switching of expression), typically due to simple DNA repeats within the gene(s) that encode them. Many bacterial species contain phase variable DNA methyltransferases that regulate epigenetics and control expression of distinct sets of proteins (phasevarions) via variable methylation of the genome. The precise mechanism of action of these regulators is unknown. Characterisation of these systems will provide better understanding of bacterial gene regulation and adaptation, which will inform biotechnology and vaccine development and could contribute to economic and health advancements.Read moreRead less

Summary
Epitranscriptomic regulation of learning and memory. This project aims to investigate m6A, the most prevalent internal modification in eukaryotic messenger RNA, in the mammalian brain. The adult brain contains a high level of reversible m6A, suggesting that m6A regulates the neuronal transcriptome during synaptic plasticity, the cellular basis of learning and memory. This project will use epitranscriptomics to investigate the more than 100 modifications on RNA, many of which are not yet characte ....Epitranscriptomic regulation of learning and memory.

The adult brain contains a high level of reversible m6A, suggesting that m6A regulates the neuronal transcriptome during synaptic plasticity, the cellular basis of learning and memory. This project will use epitranscriptomics to investigate the more than 100 modifications on RNA, many of which are not yet characterised. Through molecular and mouse behavioural assays, the expected outcomes are insights into the post-transcriptional regulation underlying learning and memory, essential for survival in a constantly changing environment.Read moreRead less

Fertility is a key driver of productivity and profitability for beef industry; however, a substantial industry challenge is poor fertility and the difficulty and expense of measuring fertility in remote Australia. By integrating multiple omics datasets and fifty thousand fertility phenotypes recorded on beef cattle, the project will identify sequence variation, including structural variants, that underpin genetic variation in cattle fertility. Our industry partner, which genotypes hundreds of thousands of cattle a year, will produce new genotype arrays and novel low-cost sequencing approaches including these variants, enabling selection that could potentially increase herd reproductive rate by 4%, returning $40M per annum to the farmers.Read moreRead less

Each cell of the human body contains identical genetic information that is activated in different ways to form varied cell types. This research aims to develop novel single-cell genomic technologies to explain the origins of different cell types. This project expects to discover the molecular mechanisms through which specialised cell types are formed, which has been difficult to decipher using existing methods. My novel approach will elucidate how a small population of seemingly homogenous cells can give rise to a myriad of types of cells. Tracing the life histories of cells across time should lead to broad applications including in developmental biology, neuroscience and immunology.Read moreRead less
