Integrons in Xanthomonas pathovars: Do they have a role in plant pathogenicity? Bacteria in the genus Xanthomonas cause serious diseases of plants, identification being based on the plant species from which they were originally recovered. Xanthomonads contain integrons, genetic elements capable of acquiring and expressing diverse genes. In other bacterial groups, the gene content of integrons varies significantly between strains of the same species, and in many cases these genes code for cell su ....Integrons in Xanthomonas pathovars: Do they have a role in plant pathogenicity? Bacteria in the genus Xanthomonas cause serious diseases of plants, identification being based on the plant species from which they were originally recovered. Xanthomonads contain integrons, genetic elements capable of acquiring and expressing diverse genes. In other bacterial groups, the gene content of integrons varies significantly between strains of the same species, and in many cases these genes code for cell surface proteins. These characteristics are precisely those we might expect to be responsible for interactions between plants and bacteria. This project aims to examine a large collection of xanthomonads for integrons, and determine whether particular integron gene contents are associated with host-pathogen specificity.

Engineering plants via modified microtubule dynamics. The plant microtubule cytoskeleton is involved in many economically important functions such as controlling growth and development, cellulose deposition, and responses to pathogens and salinity. This project will increase our understanding of how the regulation of the microtubule cytoskeleton affects these processes and move us nearer to achieving economically important goals, such as the development of crop plants with improved traits. Thi ....Engineering plants via modified microtubule dynamics.

This project will increase our understanding of how the regulation of the microtubule cytoskeleton affects these processes and move us nearer to achieving economically important goals, such as the development of crop plants with improved traits. This project will also help maintain Australia's position at the forefront of plant cell and molecular biology.Read moreRead less
Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts. This research will improve productivity of bluegum plantations by improving current diagnostic techniques (foliage and soil analysis) for nutrient disorders and the supply of water. Using a novel phloem sampling and analysis technique, we will develop a nutrient (e.g. N, P) and water diagnosis procedure that is quick, cheap, robust and reliable for field use. A major in ....Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts. This research will improve productivity of bluegum plantations by improving current diagnostic techniques (foliage and soil analysis) for nutrient disorders and the supply of water. Using a novel phloem sampling and analysis technique, we will develop a nutrient (e.g. N, P) and water diagnosis procedure that is quick, cheap, robust and reliable for field use. A major innovation will be distinguishing the effects of shortages of water on growth from those of other growth influences. Overall, this project will provide a highly significant theoretical, conceptual and practical advance in mid-rotation, diagnostics for plantations with considerable commercial promise.Read moreRead less
ARC Centre of Excellence - In Plant Energy Biology (CPEB). Plant cell metabolism underlies the synthesis of important products in crops, and subtle changes in metabolism can enhance germination rates, early seedling vigour, biomass/yield, and tolerance to harsh environments. Research in CPEB will focus on control of this metabolism. Its expertise will enhance Australia's participation in major international research efforts directly relevant to sustainable agriculture in a country with fragile/ ....ARC Centre of Excellence - In Plant Energy Biology (CPEB). Plant cell metabolism underlies the synthesis of important products in crops, and subtle changes in metabolism can enhance germination rates, early seedling vigour, biomass/yield, and tolerance to harsh environments. Research in CPEB will focus on control of this metabolism. Its expertise will enhance Australia's participation in major international research efforts directly relevant to sustainable agriculture in a country with fragile/degrading ecosystems. The research will provide new approaches for enhancing quality metabolite traits important for human health. It will further strengthen our international leadership in plant energy science, and will strengthen Australia's research training in systems biology to influence plant function.Read moreRead less
Characteristics of chlorophyll d-binding protein complexes: assembly of light-harvesting complexes. This project will investigate molecular mechanisms of photosynthesis in Chl d with the view to applying our findings in biotechnology and artificial photosynthesis. We will use a variety of molecular biology, proteomics and physical techniques to probe the bonding of Chl d to binding proteins. Synthetic peptide maquettes will provide a model to develop this understanding. Only two chlorophylls (a ....Characteristics of chlorophyll d-binding protein complexes: assembly of light-harvesting complexes. This project will investigate molecular mechanisms of photosynthesis in Chl d with the view to applying our findings in biotechnology and artificial photosynthesis. We will use a variety of molecular biology, proteomics and physical techniques to probe the bonding of Chl d to binding proteins. Synthetic peptide maquettes will provide a model to develop this understanding. Only two chlorophylls (a and d) have so far been found to take part in the primary reactions of photosynthesis. This research will grow our understanding of this pivotal process and underpin future developments in artificial photosynthesis and in the photonics industry.Read moreRead less

Climate controlled physical containment 2 (PC2) and pathogen/ insect contained glasshouse facility. The Australian economy relies heavily on agricultural production. The outcomes of the projects supported by these growth facilities will be of economic benefit to the nation by producing new knowledge of plant-insect and plant-pathogen interactions, how plants acquire essential nutrients, and how they respond to environmental stress.

The Australian economy relies heavily on agricultural production. The outcomes of the projects supported by these growth facilities will be of economic benefit to the nation by producing new knowledge of plant-insect and plant-pathogen interactions, how plants acquire essential nutrients, and how they respond to environmental stress. The research outcomes will benefit the environment by increasing legume production and so reducing land degradation and risk of nitrate contamination of waterways and lowering the environmental risk from agrochemicals by developing safer strategies for control of pests and diseases. In addition, a number of projects that will benefit from the glasshouse facilities aim to produce healthier and safer foods.Read moreRead less
