This project aims to explore metabolic diversity of Klebsiella pneumoniae, a bacterium relevant to the agricultural, veterinary, medical and biotechnology industries. It is expected to reveal significant insights into the biology of this diverse organism via an innovative combination of DNA sequence analyses and metabolic modelling. Expected outcomes include 4500 novel metabolic models and a novel population metabolic framework. This should provide major benefits for understanding bacterial ecology and evolution, and for future studies seeking to optimise industrial processes or prevent disease. It will also directly contribute to building Australia’s capacity in computational biology- a key driver of biotechnology innovation.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. By coupling innovative genetic ....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. 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

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

Transcription factors find their targets by reading the epigenetic code. This project aims to elucidate how transcription factors, proteins that regulate gene expression, find their target genes. The hypothesis is that non-DNA binding domains play an essential role in this process. This project expects to transform our understanding of transcription factor families, and how factors in families with the same DNA-binding domain manage to regulate different genes. Expected outcomes of this project ....Transcription factors find their targets by reading the epigenetic code. This project aims to elucidate how transcription factors, proteins that regulate gene expression, find their target genes. The hypothesis is that non-DNA binding domains play an essential role in this process. This project expects to transform our understanding of transcription factor families, and how factors in families with the same DNA-binding domain manage to regulate different genes. Expected outcomes of this project include revealing how accessory proteins help transcription factors identify their targets in the genome by reading epigenetic marks. This should provide significant benefits including improved design of artificial transcription factors to up- or down-regulate specific genes in research and agriculture.Read moreRead less
