This project addresses some of the most burning issues in molecular biology and genetic research, and the results will be widely applicable to a broad range of fields, including biotechnology, animal breeding, agricultural production, genetic engineering, medical science, and computational biology. By understanding the regulatory potential of microRNA molecules, we will understand more about species diversity, regulatory networks, and plant and animal development. The early adoption of multi-gigabase next-generation sequencing technology in Australia provides rare and exciting opportunity to lead the world in genome-scale research, and to ensure that Australia has the necessary skill base to remain internationally competitive in this field.Read moreRead less
A paradigm of genomic discovery - an investigation of the allelic architecture of height. Understanding the complexities of the human body from its DNA sequence has proven difficult. Genomic discovery is best developed using stable, easily measurable and highly heritable characteristics such as height. By taking advantage of 2 large population surveys of adult and adolescent stature we shall apply modern molecular techniques and statistical strategies to identify and characterise the exact chang ....A paradigm of genomic discovery - an investigation of the allelic architecture of height. Understanding the complexities of the human body from its DNA sequence has proven difficult. Genomic discovery is best developed using stable, easily measurable and highly heritable characteristics such as height. By taking advantage of 2 large population surveys of adult and adolescent stature we shall apply modern molecular techniques and statistical strategies to identify and characterise the exact changes in DNA that determine height. This work builds on substantial preliminary leads from unique resources and complementary expertise in the scientific specialties. The results from this work will inform other genomic research and provide information about growth and bone biology.Read moreRead less
Characterisation of heavy metal transport genes in the plant Arabidopsis: potential roles in metal detoxification and accumulation. Plants have considerable potential for the bioremediation ("phytoremediation") of contaminated soils, including soils polluted with heavy metals. Progress has been made in understanding the physiological and biochemical mechanisms by which plants accumulate and detoxify heavy metals. One important aspect of metal detoxification is the transport of metals across cell ....Characterisation of heavy metal transport genes in the plant Arabidopsis: potential roles in metal detoxification and accumulation. Plants have considerable potential for the bioremediation ("phytoremediation") of contaminated soils, including soils polluted with heavy metals. Progress has been made in understanding the physiological and biochemical mechanisms by which plants accumulate and detoxify heavy metals. One important aspect of metal detoxification is the transport of metals across cell membranes. The recently completed genome project for the model plant Arabidopsis has identified a family of genes encoding heavy metal transport proteins. This project aims to investigate the roles of these genes in metal detoxification. In the longer term this knowledge can be applied to the improvement of phytoremediation processes.Read moreRead less
Genetics of longevity and the delay of post-reproductive senescence. Ageing of the population in the coming decades will cause an increasing health care burden. Diseases of ageing such as Alzheimer's, heart disease, Parkinson's and a range of cancers, as well as impairments of ageing such as reduced mobility and cognitive ability are all caused or exacerbated by oxidative stress. With some exceptions, current medical practices focus on surgical repair or drug therapy to alleviate symptoms of ag ....Genetics of longevity and the delay of post-reproductive senescence. Ageing of the population in the coming decades will cause an increasing health care burden. Diseases of ageing such as Alzheimer's, heart disease, Parkinson's and a range of cancers, as well as impairments of ageing such as reduced mobility and cognitive ability are all caused or exacerbated by oxidative stress. With some exceptions, current medical practices focus on surgical repair or drug therapy to alleviate symptoms of ageing rather than addressing the physiological causes of ageing itself. Our project will provide understanding of natural systems that prevent age-related senescence due to oxidative stress. The goal is to identify novel and natural ways to maximise the fitness, well-being and self-sufficiency of people as they age.Read moreRead less

The national and community benefits of the project will be to maintain Australian leadership in advanced genetics and genome-phenome informatics. It will provide a platform for many applications in biology and biotechnology, including new genetic diagnostics and an informed basis for the engineering of complex traits in agriculture. The project will also provide insights into the structure of biological communication and control systems with applications in information science and the programming of integrated complex systems in other domains.Read moreRead less
Mechanisms of zinc transport and homeostasis in the plant, Arabidopsis. Zinc-deficiency is one of the most widespread factors limiting crop production and affects many soils of south-east and south-west Australia. Certain zinc-efficient (ZE) crop cultivars are able to grow well under zinc deficient conditions but the genetic basis for ZE is not well understood. Using a model organism such as Arabidopsis to identify genes in plants that are important in zinc transport and homeostasis will ultimat ....Mechanisms of zinc transport and homeostasis in the plant, Arabidopsis. Zinc-deficiency is one of the most widespread factors limiting crop production and affects many soils of south-east and south-west Australia. Certain zinc-efficient (ZE) crop cultivars are able to grow well under zinc deficient conditions but the genetic basis for ZE is not well understood. Using a model organism such as Arabidopsis to identify genes in plants that are important in zinc transport and homeostasis will ultimately allow us to assess whether the homologous genes in crop species are responsible for ZE. This may contribute to more rapid and directed strategies in breeding ZE crop cultivars.Read moreRead less
Inter-kingdom signalling in animal health and disease. This project aims to understand how animals can control their bacterial associates. Animals evolved in a world dominated by bacteria, and intimately associated microbes affect the development, health and disease of all animals – from corals to man. To date, animal-microbe interactions have been studied nearly exclusively in terms of how bacteria affect animals. the researchers have discovered that the coral Acropora can control its associate ....Inter-kingdom signalling in animal health and disease. This project aims to understand how animals can control their bacterial associates. Animals evolved in a world dominated by bacteria, and intimately associated microbes affect the development, health and disease of all animals – from corals to man. To date, animal-microbe interactions have been studied nearly exclusively in terms of how bacteria affect animals. the researchers have discovered that the coral Acropora can control its associated bacteria. Understanding how a simple animal manipulates its microbial associates should have implications for coral disease and resilience and for health and disease across the animal kingdom.Read moreRead less
