This project will provide new information about the molecular determinants which influence NMDA receptor channel gating that will significantly advance our understanding of a link between NMDA receptor function and many neurodegenerative diseases as well as pain and learning and memory. The outcomes of this project may lead to the discovery of novel lipid-based biomaterials for application in medicine and the drug industry. This research is highly significant in relation to human health. The biological and nutritional aspects of polyunsaturated lipids and dietary fish oils have long been recognized. Thus this project will provide further knowledge that could benefit the health of the nation with consequent reduced health care costs.Read moreRead less
Understanding the differentiation of the endocardium. The project aims to understand the genetic regulation of endocardial development. The heart is essential for survival, its beat the indicator of life. The endocardium, the heart’s inner lining, is required for signalling during heart development and is a major component of the valves, septa and trabeculae. Despite its indispensable role, little is known about how it forms or develops. This project integrates two complementary approaches that ....Understanding the differentiation of the endocardium. The project aims to understand the genetic regulation of endocardial development. The heart is essential for survival, its beat the indicator of life. The endocardium, the heart’s inner lining, is required for signalling during heart development and is a major component of the valves, septa and trabeculae. Despite its indispensable role, little is known about how it forms or develops. This project integrates two complementary approaches that have identified the earliest marker of endocardial differentiation and devised the method to make endocardium from stem cells. Knowledge from this work will inform future research into growing and regenerating damaged tissue.Read moreRead less
Kruppel-like factors and the methylome. This project aims to test the hypothesis that the KLF/SP family of transcription factors work in part via dynamic interactions with methylated cytosine nucleotides in DNA. This is fundamental to their function as pioneer factors in reprograming and their ability to co-ordinate differentiation and organogenesis. Conversely, dynamic changes in methylation status engage or disengage new regulatory elements in the genome via recruitment of KLF/SP family protei ....Kruppel-like factors and the methylome. This project aims to test the hypothesis that the KLF/SP family of transcription factors work in part via dynamic interactions with methylated cytosine nucleotides in DNA. This is fundamental to their function as pioneer factors in reprograming and their ability to co-ordinate differentiation and organogenesis. Conversely, dynamic changes in methylation status engage or disengage new regulatory elements in the genome via recruitment of KLF/SP family proteins as specific effectors. This project will address a new paradigm in genetics that is likely to underpin development.Read moreRead less
Molecular definition of cellular states in the vascular endothelium. The endothelium is the main cell type forming blood vessels and spans across multiple cell states from stem/progenitor to a variety of terminally differentiated cells. How each of these cell states are defined at the molecular level is not known preventing the optimal formation and integration of blood vessels in bioengineered tissues. Using innovative single cell gene expression and chromatin accessibility studies combined wit ....Molecular definition of cellular states in the vascular endothelium. The endothelium is the main cell type forming blood vessels and spans across multiple cell states from stem/progenitor to a variety of terminally differentiated cells. How each of these cell states are defined at the molecular level is not known preventing the optimal formation and integration of blood vessels in bioengineered tissues. Using innovative single cell gene expression and chromatin accessibility studies combined with innovative analysis, we propose to define and validate each cell state at the molecular level.
This new knowledge would greatly enhance our ability to control the transition between cell states leading to a more widespread use of endothelial cells in bioengineering of tissues globally for many applications.

The molecular evolution of wings in flightless birds. The flightless Australian emu and New Zealand kiwi have small wings, while the extinct moa had none at all. This project will identify the genetic changes that have lead to wing reduction and loss in flightless birds. The results will shed light on the genetic control of forelimb development and how it has evolved.
Beyond the gene: Linking herbivore behaviour to plant defense gene expression. This collaborative project investigates insect herbivore avoidance of plant defence mechanisms. Our project is novel because it integrates changes in the plant at a number of different levels and links them to insect foraging behaviour. Researchers assume that insects respond to plant defences by changing their foraging behaviour. This has not been tested directly. We use the genetically well characterised plant Arabi ....Beyond the gene: Linking herbivore behaviour to plant defense gene expression. This collaborative project investigates insect herbivore avoidance of plant defence mechanisms. Our project is novel because it integrates changes in the plant at a number of different levels and links them to insect foraging behaviour. Researchers assume that insects respond to plant defences by changing their foraging behaviour. This has not been tested directly. We use the genetically well characterised plant Arabidopsis and the world-wide pest Helicoverpa (heliothis) as a model system. Damage caused to crops by insect herbivores is a direct function of behaviour. Understanding this behaviour will lead to improved pest management and reduced economic losses.Read moreRead less
Discovery of pathways to embryogenesis in pathogenic flatworm parasites using microdissection and transcriptomic technologies. The cost to Australia of flatworm parasites to animal production and human health is substantial (hundreds of millions of dollars per year). This research will give new insights into how flatworms reproduce and equip their progeny for survival, providing impetus for new vaccine or drug therapies to be developed. As these pathogens are more significant in Australia's ne ....Discovery of pathways to embryogenesis in pathogenic flatworm parasites using microdissection and transcriptomic technologies. The cost to Australia of flatworm parasites to animal production and human health is substantial (hundreds of millions of dollars per year). This research will give new insights into how flatworms reproduce and equip their progeny for survival, providing impetus for new vaccine or drug therapies to be developed. As these pathogens are more significant in Australia's near neighbours, this project will strengthen Australia's international leadership in this field. Our study will provide, for the first time for any helminth parasite, a freely available genetic database that profiles the gene expression repertoire of individual parasite tissues, a development likely to enhance the international effort in controlling these harmful diseases.Read moreRead less
Insect host/vector genetic responses to rhabdovirus infection. Rhabdoviruses cause important diseases in humans, animals and plants. These viruses are transmitted by insect vectors in which they persist and propagate, an intimate and specific association. Insect-rhabdovirus interactions will be studied at the molecular level using a planthopper-maize rhabdovirus model. Insect genes specifically induced by rhabdovirus infection as well as the viral genes themselves will be identified and characte ....Insect host/vector genetic responses to rhabdovirus infection. Rhabdoviruses cause important diseases in humans, animals and plants. These viruses are transmitted by insect vectors in which they persist and propagate, an intimate and specific association. Insect-rhabdovirus interactions will be studied at the molecular level using a planthopper-maize rhabdovirus model. Insect genes specifically induced by rhabdovirus infection as well as the viral genes themselves will be identified and characterized using genomics and bioinformatics tools. We will extend the same approaches to a comparative analysis of these planthopper genes with other insect-rhabdovirus systems under investigation in our institutes. Identification of viral genes expressed in insects, the insect genes that respond to virus infection, and interpretation of the roles of these genes in insects, may indicate new opportunities to control serious plant and animal diseases through control of virus transmission.Read moreRead less

This project aims to predict the future of coral reefs in the rapidly changing climate of the Anthropocene by integrating state-of-the-art population genomics with evolutionary and ecological modelling. The project expects to describe pathways of genetic and non-genetic adaptation; and the strength and direction of connectivity of warm vs cold adapted coral populations - united in an eco-evolutionary framework. Expected outcomes address critical gaps in data and methodology that currently hinder our ability to reliably model the evolutionary and ecological dynamics of one of the most biologically diverse, socially and economically valuable and climatically vulnerable ecosystems of our planet, contributing to their science-based management.

Environmental determinants of mass extinctions by emerging disease: why does chytridiomycosis exterminate frogs in rainforest but not in open forest? The emerging fungal disease known as chytridiomycosis is causing decline and extinctions of many species of frogs around the world; Australia is no exception. Although a threat abatement plan is currently in place, a successful management strategy to deal with this problem in the wild does not exist. In the wet tropics region of north Queensland, h ....Environmental determinants of mass extinctions by emerging disease: why does chytridiomycosis exterminate frogs in rainforest but not in open forest? The emerging fungal disease known as chytridiomycosis is causing decline and extinctions of many species of frogs around the world; Australia is no exception. Although a threat abatement plan is currently in place, a successful management strategy to deal with this problem in the wild does not exist. In the wet tropics region of north Queensland, healthy populations of torrent frogs exist in the drier areas adjacent to the rainforest where they disappeared. Understanding how they coexist with this pathogen, as well as their dispersal capacity to recolonise the rainforest is basic information necessary to aid theses species in future conservation efforts.Read moreRead less
