Summary
The dynamic interplay between the matrix and cell fate in developing heart. Malformations in the developing heart can lead to catastrophic defects and embryonic loss. The valves play a critical role in blood flow regulation and are made of a stratified matrix that is laid down early in development. This project aims to determine how the cellular fate of the early valve cells establish the layered matrix and in turn how the matrix can influence cell fate by utilising a multi-omics approach to ide ....The dynamic interplay between the matrix and cell fate in developing heart. Malformations in the developing heart can lead to catastrophic defects and embryonic loss. The valves play a critical role in blood flow regulation and are made of a stratified matrix that is laid down early in development. This project aims to determine how the cellular fate of the early valve cells establish the layered matrix and in turn how the matrix can influence cell fate by utilising a multi-omics approach to identify unique cell populations and integrate transcriptional and protein changes during matrix disruption. This project expects to generate fundamental knowledge on how matrix structure can influence cell fate in the valves and will advance Australia's knowledge base and research capabilities in developmental biology.Read moreRead less

How do humans and other organisms prevent the accumulation of dangerous mitochondrial genome (mtDNA) mutations across generations? This Project aims to uncover the cellular and molecular pathways that help prevent the inheritance of mtDNA mutations to offspring by employing cutting-edge genetic technologies that the laboratory has recently developed in the germline of an animal model system. This Project will generate new knowledge in the area of mitochondrial genetics and evolution.

Expected outcomes include enhanced training of researchers and to build Australia’s capability in the rapidly expanding fields of RNA biology and high-throughput microscopy. This should provide significant benefits for a myriad of applications including health, agriculture and veterinary sciences.Read moreRead less
The control of cell signalling by membrane remodelling. Cells secrete signalling molecules called growth factors to drive critical developmental processes such as growth, differentiation and death. This project aims to understand a new mechanism that we have discovered for the control of growth factors by a protein family evolved to damage cell membranes. This is highly novel since the usual role of these proteins is to kill pathogens targeted by the immune system.

Cells secrete signalling molecules called growth factors to drive critical developmental processes such as growth, differentiation and death. This project aims to understand a new mechanism that we have discovered for the control of growth factors by a protein family evolved to damage cell membranes. This is highly novel since the usual role of these proteins is to kill pathogens targeted by the immune system. By coupling innovative genetics, high-resolution imaging, and advanced biochemical analyses, this project intends to provide key molecular insights into how cell signalling can be regulated during animal development. We anticipate that this will impact our general understanding of membrane biology and its influence on cell signalling.Read moreRead less

Molecular systems biology of novel flower colour evolution. This project aims to discover new and potentially useful structural and regulatory genes while advancing knowledge of the chemical, genetic and ecological basis of unique evolutionary flower colour shifts. Dramatic shifts in floral colour is widespread in flowering plants, however, just how changes in flower colour occur remains poorly understood.

This project will take advantage of unique Australian plants to investigate the molecular mechanisms and evolutionary shift in flower colour changes.

Foundations of a good egg: correctly transitioning from mitosis to meiosis. Production of viable offspring is essential to the survival of any species. In all sexually reproducing species, this requires a unique cell type, the germ cell. Germ cells undergo a special type of cell division, called meiosis, so that they can eventually produce gametes (sperm in males and eggs in females). This project aims to discover how germ cells halt the standard form of cell division, called mitosis, and initia ....Foundations of a good egg: correctly transitioning from mitosis to meiosis. Production of viable offspring is essential to the survival of any species. In all sexually reproducing species, this requires a unique cell type, the germ cell. Germ cells undergo a special type of cell division, called meiosis, so that they can eventually produce gametes (sperm in males and eggs in females). This project aims to discover how germ cells halt the standard form of cell division, called mitosis, and initiate meiotic division instead. It is important to understand all the fundamental processes that occur during normal germ cell development so that, in the future, we can use this knowledge to support agricultural advances, rescue endangered species and solve human problems such as infertility and genetic disease.Read moreRead less

Sustainable, productive agricultural processes are essential for tackling the challenges of tomorrow’s world. The ability to optimise beneficial agricultural traits depends on the precise control of genes in a crop plant’s enormous genome. Yet, identifying valuable gene control regions is like looking for needles in a haystack. The location of these regions is often not obvious and current detection technologies are impractically expensive and intensive. This project aims to develop a new technology that is expected to facilitate rapid and cost-effective discovery of all the control regions in a genome, enhancing our understanding of crop genomes and unlocking new avenues for agricultural improvement, food security and economic stability.Read moreRead less
An integrated molecular approach to human gene regulation. This proposal aims to reveal how the interaction of nuclear RNA and protein molecules control gene regulation in the face of cell stress.

This proposal aims to reveal how the interaction of nuclear RNA and protein molecules control gene regulation in the face of cell stress. To understand how genetic variation leads to changes in the expression of genes, we need new insights into the fundamental principles underpinning complex gene regulatory systems. Building on the discovery of paraspeckles, novel gene regulatory structures, this project will yield insights into gene regulation that will help fill these knowledge gaps. This will provide a more comprehensive understanding of RNA-mediated gene regulation, and will open up new research opportunities to target RNA based gene regulatory complexes.Read moreRead less

Plant genomics has moved to the single cell resolution, allowing precise investigations of previously hidden cell types and cell states that respond to environmental stress and that vary among differentially adapted plant populations. Here, we will extend our pioneering efforts that have mapped and discovered novel root cell types, to determine their salt and nutrient stress responses, and to elegantly dissect the underling causal genetic variation. The unique cell markers and regulatory networks will be validated with tissue specific and transgenic tools that can work across a host of plant species to reveal adaptive cellular responses to harsh environmental conditions.Read moreRead less
