Evolution and the immune system: genetic differences in immune response between human populations due to adaptation to living in different geo-climatic locations. The project, which investigates the genetics of inter-population differences in immune response, will lead to advances in immunology and population genetics research, explain present population specific differences in disease incidence and possibly forecast future population trends of diseases such as asthma and allergy. The study will ....Evolution and the immune system: genetic differences in immune response between human populations due to adaptation to living in different geo-climatic locations. The project, which investigates the genetics of inter-population differences in immune response, will lead to advances in immunology and population genetics research, explain present population specific differences in disease incidence and possibly forecast future population trends of diseases such as asthma and allergy. The study will strengthen ties with collaborators around the world, thus promoting excellence in Australian research and gain Australia prestige in the international community as a country that produces research of global significance. Understanding the immune system's 'recent evolutionary roots' has implications for the health of Australians, especially in light of Australia's increasingly multi-ethnic background.Read moreRead less
Population dynamics and genetic variation of plants with contrasting fire responses. We combine the traditional concerns of population viability analyses with the modern techniques of DNA fingerprinting for precise genotyping of individual plants and their seeds. We expect major breakthroughs in our understanding of how fire-killed species have survived thousands of years of frequent burning by Aborigines (by identifying seeds dispersed long distances from burnt parents); how paternity of offspr ....Population dynamics and genetic variation of plants with contrasting fire responses. We combine the traditional concerns of population viability analyses with the modern techniques of DNA fingerprinting for precise genotyping of individual plants and their seeds. We expect major breakthroughs in our understanding of how fire-killed species have survived thousands of years of frequent burning by Aborigines (by identifying seeds dispersed long distances from burnt parents); how paternity of offspring changes over the lifespan of plants which retain their seeds for many years; at what age within-plant genetic variation is at a maximum as a guide to optimal fire management; and the extent that deleterious somatic mutations explain low seed set among long-lived species.Read moreRead less

Drugging the undruggable: Development of novel technologies to selectively regulate the expression of targets driving cancer and other diseases. Transcription factors are “undruggable” targets playing a principal role driving cancer. This project will create novel therapeutic strategies to inhibit transcription factors and other elusive targets differentially expressed in diseased cells, without affecting normal tissue.

Transcription factors are “undruggable” targets playing a principal role driving cancer. This project will create novel therapeutic strategies to inhibit transcription factors and other elusive targets differentially expressed in diseased cells, without affecting normal tissue. It proposes to construct engineered proteins able to bind and modify specific key genes deregulated in cancer, to correct their expression and stably reprogram the phenotype of the tumour cell in a normal-like state. It outlines the engineering of novel synthetic agents to block specific protein-protein interactions in cancer cells and to induce potent tumour cell death. This work will generate novel and selective therapeutics to treat un-curable forms of tumours.Read moreRead less
Quantifying long-distance seed dispersal and its role in the metapopulation dynamics of plants with contrasting life histories. This work will contribute to the assessment of best fire-management practices, enabling land managers to compare current fire practices against those required for conservation of genetic resources. Our quantification of Long distance seed dispersal (LDD) among species with different life history attributes will be a major theoretical contribution to the fields of popula ....Quantifying long-distance seed dispersal and its role in the metapopulation dynamics of plants with contrasting life histories. This work will contribute to the assessment of best fire-management practices, enabling land managers to compare current fire practices against those required for conservation of genetic resources. Our quantification of Long distance seed dispersal (LDD) among species with different life history attributes will be a major theoretical contribution to the fields of population ecology and population genetics. LDD is also imperative if species are to survive the major shifts in climate projected under modelled climate change scenarios - species without effective LDD may have a greater probability of extinction due to climate change. Assessing LDD enables quantification of this significant aspect of the threat of climate change to biodiversity.Read moreRead less
Transcriptome sequencing and functional characterisation of craniate non-visual sensory systems and their adaptation to diverse light environments. Light detection (photoreception) is critical to species survival. It is not limited to vision, but also serves to set biological rhythms. In mammals, all photoreception is thought to occur solely through the eye, but in non-mammals many other tissues directly monitor light levels. However, the signalling cascades and functional roles of these non-vis ....Transcriptome sequencing and functional characterisation of craniate non-visual sensory systems and their adaptation to diverse light environments. Light detection (photoreception) is critical to species survival. It is not limited to vision, but also serves to set biological rhythms. In mammals, all photoreception is thought to occur solely through the eye, but in non-mammals many other tissues directly monitor light levels. However, the signalling cascades and functional roles of these non-visual pathways are largely unknown. This project will use high-throughput sequencing technologies and functional analyses to trace the origin and function of different irradiance detection systems in each main craniate class. By comparing species from diverse photic habitats, the influence of light as a substrate for adaptation will be investigated.Read moreRead less

DNA is the molecule of life and exists everywhere in the environment as a largely untapped source of information on evolution, biodiversity, and ecosystem health. Our overriding aim is to start mining that information to benefit threatened species. Based on optimized ancient DNA methods, powerful sequencing technology, whole genome analyses, and RNA profiling, we present a novel and holistic framework for genetic biomonitoring. In two parallel model systems we will study corals and reptiles to improve environmental detection while simultaneously obtaining information on their population health. This will foster more efficient conservation of endangered species that are of tremendous importance to our marine and terrestrial ecosystems.Read moreRead less
The Epigenetics of Sex in the Dragon. Genetic codes do not directly translate to phenotypes -- environment acts through epigenetics to modify development. We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway? Which ....The Epigenetics of Sex in the Dragon. Genetic codes do not directly translate to phenotypes -- environment acts through epigenetics to modify development. We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway? Which sex genes are targets? Epigenetic enzymes are astonishingly conserved, providing exciting opportunities to draw from human systems to unravel novel signatures of temperature-induced sex switching in reptiles. This project will advance knowledge of developmental programming generally.Read moreRead less
Dispersal and persistence of large-seeded forest species under global environmental change. This project investigates how decline of a key seed disperser, the emu, due to global environmental change (fragmentation, fire regime change, human population growth, climate change) affects the persistence and migration potential of endemic SW Australian forest plant species. Results will inform approaches to ecosystem management and conservation
