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
Genomic Basis of Resistance to Poisoning by Sodium Fluoroacetate (Compound 1080) in Australian Wildlife. In Australia agricultural conservation activities worth billions of dollars are protected by using sodium fluoroacetate (1080) against pest animals. Target species are Australian rabbits and foxes and New Zealand brushtail possums. Prolonged use of biocontrol agents causes genetic resistance. This occurs naturally in Western Australia in native animals living in areas with high levels of 1080 ....Genomic Basis of Resistance to Poisoning by Sodium Fluoroacetate (Compound 1080) in Australian Wildlife. In Australia agricultural conservation activities worth billions of dollars are protected by using sodium fluoroacetate (1080) against pest animals. Target species are Australian rabbits and foxes and New Zealand brushtail possums. Prolonged use of biocontrol agents causes genetic resistance. This occurs naturally in Western Australia in native animals living in areas with high levels of 1080 in native plants. As part of the Kangaroo Genome project our aim is to discover the genomic basis of this resistance. The outcomes will be improved ability to manage pest animal populations and understanding of the evolution of plant-animal interactions.Read moreRead less
Are neurobehavioural and neuromotor impairments associated with FMR1 gene expansion? The gene that causes Fragile X syndrome is found at the end of the X chromosome and is present in all humans. In many cases there is a small to medium change in this gene that may cause psychological and motor difficulties in later adulthood. The core aim of this project is to identify early age-related changes that would indicate later neurological decline.
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
Epigenetic integration of genomic and environmental information in honey bees. Environmental factors such as nutrition, drugs or childhood neglect alter gene activity without a change to the DNA code and may result in a range of conditions such as cancer, obesity and mental illness. Such epigenetic phenomena are driven by subtle and poorly understood modifications of the genome known as DNA methylation. Our aim is to study the link between DNA methylation and environmental influences. We aspire ....Epigenetic integration of genomic and environmental information in honey bees. Environmental factors such as nutrition, drugs or childhood neglect alter gene activity without a change to the DNA code and may result in a range of conditions such as cancer, obesity and mental illness. Such epigenetic phenomena are driven by subtle and poorly understood modifications of the genome known as DNA methylation. Our aim is to study the link between DNA methylation and environmental influences. We aspire to understand how environmental signals trigger the reprogramming of transcriptional control of genetic networks that lead to contrasting phenotypic and behavioural outcomes using the honey bee modelRead moreRead less

Dissecting insect gut function to understand insecticide detoxification. Massive quantities of chemical insecticides are used daily to control the insect pests that threaten agriculture, human health and the welfare of domestic pets. Insects readily evolve resistance to these chemicals reducing the effectiveness of pest control, increasing the amount of chemical used and increasing costs to consumers. This project examines the way in which insects adapt to the extreme stress imposed on them by ....Dissecting insect gut function to understand insecticide detoxification. Massive quantities of chemical insecticides are used daily to control the insect pests that threaten agriculture, human health and the welfare of domestic pets. Insects readily evolve resistance to these chemicals reducing the effectiveness of pest control, increasing the amount of chemical used and increasing costs to consumers. This project examines the way in which insects adapt to the extreme stress imposed on them by chemical insecticides. A thorough understanding of this adaptation process is required before insecticide resistance can be effectively managed or prevented. Read moreRead less
Potential of gene drives to eliminate incursions of Drosophila suzukii. This project aims to test the efficacy and evolutionary stability of different types of gene drives, and model whether gene drives can be used to eliminate incursions of Drosophila suzukii into Australia.

This project aims to test the efficacy and evolutionary stability of different types of gene drives, and model whether gene drives can be used to eliminate incursions of Drosophila suzukii into Australia. It is now possible to use genome editing technology to alter populations of organisms using ‘gene drives’. Multiple strategies have been conceived with a major distinction between those that aim to eliminate populations versus those that aim to modify populations. This project will examine these strategies in two fly species, the model, Drosophila melanogaster and the devastating pest of horticulture, Drosophila suzukii. The project expects to assess a gene drive strategy to control the invasive pest that threatens the Australian soft-skinned fruit industries.Read moreRead less
Searching for genes influencing reading ability using multivariate genomic linkage analysis and allelic association analysis. Following from the replicated linkages of reading disability to loci on chromosomes 6 & 18, this study examines linkage of these same regions to a range of reading measures in an unselected sample of twins and siblings. Preliminary univariate linkage scans of two neuropsychological reading indices suggest linkage to loci on two chromosomes. Our next step is to include rea ....Searching for genes influencing reading ability using multivariate genomic linkage analysis and allelic association analysis. Following from the replicated linkages of reading disability to loci on chromosomes 6 & 18, this study examines linkage of these same regions to a range of reading measures in an unselected sample of twins and siblings. Preliminary univariate linkage scans of two neuropsychological reading indices suggest linkage to loci on two chromosomes. Our next step is to include reading measures of orthographic skill and phonological decoding in a multivariate linkage analysis with the other reading indices and with measures of IQ and academic achievement. Multivariate linkage increases the power of detecting quantitative traits and assists in defining the phenotype related to the locus. We then aim to identify the functional gene through allelic association analysis. Identification of QTLs for reading ability may lead to practical outcomes such as the behavioural and biomedical management of reading deficits, which may then benefit areas such as scholastic achievement.Read moreRead less
