Molecular and genetic analysis of epigenetic components in a model plant. Australia is a major exporter of agricultural food crops thus producers must maintain their competitive advantage in order to compete on the world stage. Food crops unfortunately have large, complex genomes that are not sequenced and a generation time of months that makes research outcomes slow to achieve. This project proposes to utilise a model plant that has a small completely sequenced genome and a short generation tim ....Molecular and genetic analysis of epigenetic components in a model plant. Australia is a major exporter of agricultural food crops thus producers must maintain their competitive advantage in order to compete on the world stage. Food crops unfortunately have large, complex genomes that are not sequenced and a generation time of months that makes research outcomes slow to achieve. This project proposes to utilise a model plant that has a small completely sequenced genome and a short generation time making it ideal to study the fundamental biological process of RNA silencing. Discoveries and outcomes from this project may have the potential to benefit Australian crops, ecosystems and human health.Read moreRead less

The Insect-Plant Chemical Ecology Network (IPCEN). We bring together plant molecular biology, entomology and analytical chemistry to transform three leading fields of Australian research into an advanced science with far reaching capabilities in innovative research and applied outcomes.

We bring together plant molecular biology, entomology and analytical chemistry to transform three leading fields of Australian research into an advanced science with far reaching capabilities in innovative research and applied outcomes. Expertise studying the biochemical pathways that produce specific plant compounds and expertise in insect recognition and response to these chemicals will be brought together. This will lead to new research outcomes and solutions to problems in agriculture, horticulture, forestry and protection of Australia's native flora. Researchers are struggling to create these links, constrained by disciplinary boundaries and geographical isolation. Key industries and researchers already support this proposal.Read moreRead less

Development of cloning technology for the Australian Pig Industry. Cloning has the potential to be the most efficient of the reproductive technologies developed for increasing genetic improvement in livestock. Currently up to 5% of cloned embryos develop to term in the pig. This is higher than that reported for cattle and sheep. Moreover the use of this technology in the pig does not appear not to result in the same sorts of problems and losses seen around the time of birth in these species ....Development of cloning technology for the Australian Pig Industry. Cloning has the potential to be the most efficient of the reproductive technologies developed for increasing genetic improvement in livestock. Currently up to 5% of cloned embryos develop to term in the pig. This is higher than that reported for cattle and sheep. Moreover the use of this technology in the pig does not appear not to result in the same sorts of problems and losses seen around the time of birth in these species i.e. the majority of cloned pigs appear normal and are healthy at birth. However before cloning can be used commercially, current efficiencies need to be increased approx two fold for this to be economically viable. The aim of the present study is to improve the efficiency of our current cloning protocol and develop associated technologies such as embryo freezing to facilitate commercialisation. This will ensure that the Australian Pig Industry remains competitive at a pivotal time in its development.Read moreRead less
Cyclostome bryozoans: Their use as paleoceanographic, paleoclimatologic and paleoenvironmental proxies throughout the cenozoic of southern Australia. The unravelling of ocean evolution relies largely on data from fossils - geochemical proxies of ancient oceans. Southern Australia contains an inrivalled 45 million-year old record of cool-water carbonate sedimentation and thus global paleoceanography. Currently, the only proxies available in these extensive sediments are brachiopods and planktic f ....Cyclostome bryozoans: Their use as paleoceanographic, paleoclimatologic and paleoenvironmental proxies throughout the cenozoic of southern Australia. The unravelling of ocean evolution relies largely on data from fossils - geochemical proxies of ancient oceans. Southern Australia contains an inrivalled 45 million-year old record of cool-water carbonate sedimentation and thus global paleoceanography. Currently, the only proxies available in these extensive sediments are brachiopods and planktic foraminfers. However, these sediments contain prolific low-magnesium calcite bryozoans, particularly cyclostomes, that could be used instead. This research will assess such bryozoans and test their usefulness and reliability, utilising existing extensive modern marine and Tertiary samples, data bases and sections. Such potential proxies would be globally useful for limestones from the last 500My.Read moreRead less
Endosymbiotic DNA transfer. Interorganellar DNA movement is a major force in evolution. In higher organisms, the prokaryotic ancestors of mitochondria and chloroplasts donated many genes to the nucleus. Plants have unique potential in studies of the mechanisms that have driven genome evolution. We established experimentally that DNA moves from the chloroplast to the nucleus at high frequency and this provided us with a world lead in this scientifically new area.

In higher organisms, the prokaryotic ancestors of mitochondria and chloroplasts donated many genes to the nucleus. Plants have unique potential in studies of the mechanisms that have driven genome evolution. We established experimentally that DNA moves from the chloroplast to the nucleus at high frequency and this provided us with a world lead in this scientifically new area. The relocated genes contribute to the number and diversity of genes and gene function. Genetically manipulated (GM) crops use the chloroplast compartment to make high levels of protein, necessitating a full understanding of how transgenes behave within the cellular and the external environment.Read moreRead less

To achieve net-zero carbon emissions in Australia by 2050, this project proposes to develop carbon-negative concrete using two typical industrial wastes, recycled powder from construction and demolition waste and drinking water treatment sludge from the water industry. This project first aims to develop innovative artificial aggregates containing sludge-derived biochar and recycled powder under carbonation curing. The developed artificial aggregates with superior carbon absorption capacity are then used to produce carbon-negative concrete. The properties of artificial aggregates and carbon-negative concrete will be comprehensively investigated. This project creates a green engineering solution to stockpiled industrial wastes.

Trafficking of DNA between chloroplast and nucleus in higher plants. Reliably high levels of diverse proteins can be produced in plant chloroplasts. Environmental risks are considered low for chloroplast genes because they are not transmitted by pollen. However, we recently discovered that DNA escapes from the tobacco chloroplast to the nucleus with unexpectedly high frequency. The associated environmental risks require immediate investigation. This project will determine the fate of chloroplast ....Trafficking of DNA between chloroplast and nucleus in higher plants. Reliably high levels of diverse proteins can be produced in plant chloroplasts. Environmental risks are considered low for chloroplast genes because they are not transmitted by pollen. However, we recently discovered that DNA escapes from the tobacco chloroplast to the nucleus with unexpectedly high frequency. The associated environmental risks require immediate investigation. This project will determine the fate of chloroplast DNA that has moved to the nuclear genome and gain insight into the evolutionary and environmental consequences of chloroplast DNA escape. The ubiquity of DNA escape also will be studied in an edible crop with a small genome, tomato.Read moreRead less
