Feasting on protein? Strategies of organic nitrogen acquisition by plant roots. Crops require large amounts of nitrogen for growth. Application of nitrogen fertiliser enhances yield, but causes off-site nitrogen pollution, a main threat to ecosystem integrity. Most nitrogen in soil occurs as organic complexes that are broken down by soil organism into small compounds, which are taken up roots or lost from the soil. This project will generate fundamental knowledge of how an Australian species and ....Feasting on protein? Strategies of organic nitrogen acquisition by plant roots. Crops require large amounts of nitrogen for growth. Application of nitrogen fertiliser enhances yield, but causes off-site nitrogen pollution, a main threat to ecosystem integrity. Most nitrogen in soil occurs as organic complexes that are broken down by soil organism into small compounds, which are taken up roots or lost from the soil. This project will generate fundamental knowledge of how an Australian species and a crop species with unusual root specialisations access soil organic nitrogen, thus increasing the efficiency of nitrogen use and reducing nitrogen loss. The research employs cutting-edge techniques for sustainable resource use, improved efficiency of crops and farming systems, and preservation of Australia's biodiversity.Read moreRead less
Eco-Turf: Water and nutrient use efficient turfgrasses from Australian biodiversity. Domestic water consumption in Australia is approximately 30% higher than the OECD average. Approximately one third of domestic water consumption is applied to the garden, including turfgrass lawns. Turfgrasses are significant users of fertilisers, which can lead to problems with runoff and infiltration into the water table. We will use the unique diversity of Australian couch grasses to identify new turfs for ....Eco-Turf: Water and nutrient use efficient turfgrasses from Australian biodiversity. Domestic water consumption in Australia is approximately 30% higher than the OECD average. Approximately one third of domestic water consumption is applied to the garden, including turfgrass lawns. Turfgrasses are significant users of fertilisers, which can lead to problems with runoff and infiltration into the water table. We will use the unique diversity of Australian couch grasses to identify new turfs for domestic, sportsground and amenity lawns. This project will develop tools to select turfgrasses that maintain quality with reduced inputs of water and nutrients, leading to an overall reduction in resource use and downstream ecological effects. Benefits of this project extend to urban and rural communities Australia-wide.Read moreRead less
Regulation of ion homeostasis by two-component signalling elements. Dryland salinity is continuously claiming Australian lands and is a serious threat to our agricultural industry, native flora and fauna, and infrastructure. Attempting to feed an increasing population whilst agricultural land is disappearing, places an ever-increasing burden on our remaining land. While there is no simple solution to this problem, understanding how plants regulate cellular ion concentrations will help to generat ....Regulation of ion homeostasis by two-component signalling elements. Dryland salinity is continuously claiming Australian lands and is a serious threat to our agricultural industry, native flora and fauna, and infrastructure. Attempting to feed an increasing population whilst agricultural land is disappearing, places an ever-increasing burden on our remaining land. While there is no simple solution to this problem, understanding how plants regulate cellular ion concentrations will help to generate plants that are suitable for restoration of damaged lands or crop plants that are more tolerant to saline soils. Furthermore, knowledge acquired from the proposed project will also be useful for generating healthier crop plants with enhanced levels of ions essential for the human diet. Read moreRead less

A novel link between plant pathogen defence and DNA repair capability. Plants and plant-based industries are essential for the provision of food, clothing and building materials and underpin the economies of rural communities.

Plants and plant-based industries are essential for the provision of food, clothing and building materials and underpin the economies of rural communities. Plant yield and quality and the biodiversity of natural systems are dramatically reduced by disease. The fundamental knowledge gained from our research will enable manipulation of the factors that enhance disease resistance resulting in a significant benefit to Australian agriculture and protection of our natural resources. The current reliance for disease control on chemicals that damage the environment will be reduced and our research will contribute directly to the provision of cheaper, simpler and more effective methods of control.

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

Modern molecular tools have lead to an explosion in genome projects and unification of all areas of biology. The most basic need for such research is access to improving technologies for detecting DNA fingerprints that distinguish genetically-diverse genes, and determining which genes are "switched on" or 'off' in various situations. Real time PCR technology, pioneered by The University of Queensland (UQ) and Southern Cross University (SCU) using ARC funding in 1996, is now the technology of choice for much of this research. This project will provide high-throughput equipment for real time PCR, and will develop complementary high-throughput "nanoparticle" DNA genotyping technologies, with applications to medicine and agriculture.

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
