This project aims to develop and apply a novel targeted sequence capture and high throughput DNA sequencing approach to simultaneously type thousands of informative identity, ancestry and phenotype markers in a single assay to facilitate identification of unknown suspects and missing persons. DNA based human identification is both critical and central to criminal and coronial investigations, disaster-victim and missing persons identification, repatriation of war dead and counter-terrorism operations. Persistent technological and conceptual issues associated with the application of standard procedures to trace degraded DNA, or when profiles have no match in DNA databases, limit their application to real-world human identification problems.Read moreRead less
The birth and death of mammalian sex chromosomes. This project aims to unravel the molecular mechanisms that underlie the transition from autosome to sex chromosome and progressive sex chromosome differentiation in mammals. Monotremes are the only mammalian species with a sex chromosome system that consists of ten sex chromosomes in platypus and nine in echidna. This project will analyse the genetic and epigenetic composition and organisation of the monotreme autosomes that evolved into sex chro ....The birth and death of mammalian sex chromosomes. This project aims to unravel the molecular mechanisms that underlie the transition from autosome to sex chromosome and progressive sex chromosome differentiation in mammals. Monotremes are the only mammalian species with a sex chromosome system that consists of ten sex chromosomes in platypus and nine in echidna. This project will analyse the genetic and epigenetic composition and organisation of the monotreme autosomes that evolved into sex chromosomes in other mammals and compare individual platypus and echidna sex chromosomes to discover how sex chromosomes come to be, differentiate and ultimately are replaced by new sex chromosomes.Read moreRead less
The evolutionary origin, cellular response and genetic impact of insecticide resistance mutations in agricultural pests. Diamondback moth is a global pest of canola and Brassica vegetables, and populations can rapidly evolve resistance to insecticides. The project will use a combination of genome sequencing, fieldwork and gene expression analysis to identify mutations causing resistance to Bt insecticidal toxins and assess the threat of resistance evolving in Australia.
Defining pathways that establish and maintain reproductive cell identity in plant ovules and seeds. Unlike animals, individual somatic cells in plants have the remarkable ability to regenerate into new plants, depending on the signals they perceive. This developmental plasticity is particularly important during normal plant growth, when mature cells adopt new identities within multicellular environments. Tissue complexity is critical for the utilisation of plants in society as food, fuel and fib ....Defining pathways that establish and maintain reproductive cell identity in plant ovules and seeds. Unlike animals, individual somatic cells in plants have the remarkable ability to regenerate into new plants, depending on the signals they perceive. This developmental plasticity is particularly important during normal plant growth, when mature cells adopt new identities within multicellular environments. Tissue complexity is critical for the utilisation of plants in society as food, fuel and fibre, but how and why plant cells adopt or change identity has been difficult to determine. This project aims to employ next-generation molecular methods to identify pathways driving differentiation of specific ovule and seed cell-types, which directly impact crop quality, yield and end-use.Read moreRead less

The advanced DNA identification and forensics facility:
The project aims to establish a national integrated facility for cutting-edge forensic genetic research, resources and expertise in wildlife, forest and environmental DNA identification to improve our capacity to identify unknown biological material. The project’s goal will be to enhance synergies between academic research, service delivery and forensic application of DNA identification technologies, addressing vital questions such as: From which individual or species did this material originate? Where in the world is it from? Is it legal? The proposed facility may deliver applied outcomes for government, the criminal justice system, and industry, such as improved pest and threatened species identification; biosecurity, prosecutions of wildlife crime and illegal logging; and missing person and disaster victim identification.Read moreRead less
The genomic landscape of speciation in hominins and other taxa. This project will develop a new analytical framework to build detailed genomic maps of speciation genes across different taxa, to determine whether observed speciation is the result of background selection and demography alone, or whether there are actual barriers to gene flow and introgressed DNA. The model will provide novel insights into the mechanistic basis of speciation, specifically whether a common set of genes or pathways a ....The genomic landscape of speciation in hominins and other taxa. This project will develop a new analytical framework to build detailed genomic maps of speciation genes across different taxa, to determine whether observed speciation is the result of background selection and demography alone, or whether there are actual barriers to gene flow and introgressed DNA. The model will provide novel insights into the mechanistic basis of speciation, specifically whether a common set of genes or pathways are central to the speciation process. The framework will be developed using the large genomic datasets available across a range of plant and animal species. Applying the model to a modern human population dataset will elucidate the role introgressed DNA from Denisovan and Neanderthals has played in shaping human evolutionary history and may provide novel insights into the genetic basis of disease.Read moreRead less

Sustaining crop yield and maintaining food security is a significant worldwide concern. This project aims to strengthen insect pest control strategies and improve bio-insecticide use in agriculture through better understanding of the mode of action of Bacillus thuringiensis (Bt) insecticides. It aims to improve their efficacy and evaluate opportunities to develop bio-insecticides based on plant saponins. This will assist in determining the risk of insecticide resistant moths migrating to Australia, and within our borders. This project aims to provide opportunities to improve transgenic Bt-crops and Bt-sprays, provide commercial development of new bio-insecticides, and develop optimal control strategies for major Australian migratory pests.Read moreRead less

This project aims to address the need for a Queensland fruit fly male-only sterile release strain for the national Sterile Insect Technique program to control this devastating Australian horticulture pest. By combining two molecular technologies in a new strain that responds to temperature cues to trigger development of only male flies, this project expects to produce twice as many sterile males for release to mate with wild females in fruit fly outbreak areas, preventing production of the next generation. Expected outcomes include significant reduction in production costs and increased efficiency of the national sterile release program, facilitating control of this damaging pest to protect Australia's billion dollar horticultural industry.Read moreRead less
