Summary
Genes, reproduction and inheritance in a microbe. The project aims to particularly explore sexual gene inheritance in Plasmodium, a representative of a large group of human and animal parasites. Plasmodium must have a sexual exchange of genes in the mosquito for the transfer of disease to a new host. This project will investigate the fate and behaviour of Plasmodium genes during reproduction; the differing chromosome states resulting from sexual genetic processes and the asymmetrical inheritance ....Genes, reproduction and inheritance in a microbe. The project aims to particularly explore sexual gene inheritance in Plasmodium, a representative of a large group of human and animal parasites. Plasmodium must have a sexual exchange of genes in the mosquito for the transfer of disease to a new host. This project will investigate the fate and behaviour of Plasmodium genes during reproduction; the differing chromosome states resulting from sexual genetic processes and the asymmetrical inheritance of some Plasmodium genes. The project is expected to advance Australia’s ability to understand the reproduction and survival of these parasites in their mosquito vector and develop cutting-edge genetic tools that will advance the microbial genetics discipline globally. This may ultimately lead to biotechnology and biomedical outcomes.Read moreRead less
Defining the Molecular Targets of Evolution. With significant advances in next-generation sequencing technologies we now have the genomes of hundreds vertebrate species, but understanding how the differences and similarities within these genomes control species diversity is largely unknown. The similarity in skull shape between the thylacine and dogs coupled with their deep ancestry, having last shared a common ancestor over 160 million years ago, provides an unprecedented opportunity to examine ....Defining the Molecular Targets of Evolution. With significant advances in next-generation sequencing technologies we now have the genomes of hundreds vertebrate species, but understanding how the differences and similarities within these genomes control species diversity is largely unknown. The similarity in skull shape between the thylacine and dogs coupled with their deep ancestry, having last shared a common ancestor over 160 million years ago, provides an unprecedented opportunity to examine how evolution works at the DNA level. This proposal will determine if animals that develop identical skull shapes, also show identical changes in their DNA. The findings will define new developmental genes and explain how selection, adaptation and evolution works at the DNA level. Read moreRead less
Function and evolution of insect odorant receptors. This project aims to shed light on how insect odorant receptors function by using comparative genomic studies between the genetic model insect Drosophila melanogaster and a pest species, the Australian sheep blowfly. This project expects to generate knowledge of how specific chemicals activate specific receptors in order to excite sensory neurons and drive behaviour, which is not well understood. Expected outcomes include increased understandin ....Function and evolution of insect odorant receptors. This project aims to shed light on how insect odorant receptors function by using comparative genomic studies between the genetic model insect Drosophila melanogaster and a pest species, the Australian sheep blowfly. This project expects to generate knowledge of how specific chemicals activate specific receptors in order to excite sensory neurons and drive behaviour, which is not well understood. Expected outcomes include increased understanding of olfaction in insects, increased national and international collaboration, and outstanding graduate student training. This research will be of significant future benefit in deriving methods to modify the behaviour of insects of agricultural or medical importance, for example the sheep blowfly. Read moreRead less
Characterising a new regulator of the Hedgehog pathway . The Hedgehog pathway is crucial for embryonic development, and disruption causes multi-organ morphogenesis defects. The CI team has uncovered a new gene required for Hedgehog signalling in mouse, zebrafish, and Drosophila. Preliminary data hints at mechanism for this novel gene and shows it may in fact be a member of a new superfamily. The project will examine gene function and identify interacting protein partners, using the zebrafish, Dr ....Characterising a new regulator of the Hedgehog pathway . The Hedgehog pathway is crucial for embryonic development, and disruption causes multi-organ morphogenesis defects. The CI team has uncovered a new gene required for Hedgehog signalling in mouse, zebrafish, and Drosophila. Preliminary data hints at mechanism for this novel gene and shows it may in fact be a member of a new superfamily. The project will examine gene function and identify interacting protein partners, using the zebrafish, Drosophila, and cell-based models. Findings will provide basic knowledge about this mysterious gene and uncover how it modulates an essential pathway in embryonic development. This research is expected to impact knowledge generation, health, and well-being.Read moreRead less

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
Visualising chromatin changes in 3 dimensions: super to ultra resolution. Packaging of genomic information into the nucleus of a cell necessitates the formation of tightly compacted and highly organized genomic structures within the nucleus, a configuration that is inherently repressive for gene transcription. Hence, mechanisms that alter the spatial organisation of DNA are critical to enable a variety of genome functions, including DNA transcription. This proposal will utilise novel adaptations ....Visualising chromatin changes in 3 dimensions: super to ultra resolution. Packaging of genomic information into the nucleus of a cell necessitates the formation of tightly compacted and highly organized genomic structures within the nucleus, a configuration that is inherently repressive for gene transcription. Hence, mechanisms that alter the spatial organisation of DNA are critical to enable a variety of genome functions, including DNA transcription. This proposal will utilise novel adaptations of super resolution microscopy to visualise in 3 dimensions how changes in chromatin modifications impact genome spatial organisation within the nucleus, and how this then links to cellular differentiation. This will provide a picture of how spatial organisation within the nucleus supports general cell differentiation.
