Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial ana ....Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial analysis and modelling methods. Expected outcomes are a mechanistic understanding of tree-mediated methane fluxes, helping to constrain regional, national and global methane budgets. The results of this study will help inform publicly funded greenhouse gas abatement strategies, ensuring a maximal return on investment.Read moreRead less
Comparative eco-physiology of two contrasting arid-zone woodlands in Central Australia: hydrological niche separation and ecosystem resilience. This proposal addresses two fundamental questions: how do co-occurring species co-exist and why do Australian ecosystems have larger ecosystem water-use-efficiencies than those in the USA? This proposal will: determine the resilience of two contrasting arid-zone woodlands; compare variation in hydraulic-related plant traits across co-existing species; an ....Comparative eco-physiology of two contrasting arid-zone woodlands in Central Australia: hydrological niche separation and ecosystem resilience. This proposal addresses two fundamental questions: how do co-occurring species co-exist and why do Australian ecosystems have larger ecosystem water-use-efficiencies than those in the USA? This proposal will: determine the resilience of two contrasting arid-zone woodlands; compare variation in hydraulic-related plant traits across co-existing species; and, determine the relative contribution of changes in assimilation and stomatal conductance to variation (across species and time) in water-use-efficiency. Outcomes of this work include a mechanistic understanding of the behaviour of water-limited woodlands in current and future climates. This is significant because such biomes are globally important and are home to two billion people. Read moreRead less
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.

This project will also help maintain Australia's position at the forefront of plant cell and molecular biology.Read moreRead less
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.

Peridinin-chlorophyll-protein complex: unravelling the unique photosynthetic apparatus of dinoflagellates in response to climatic variation. Dinoflagellates sustain the food chain. They live in coral and in ice, and also create toxic algal blooms. This project will dissect the unique photosynthetic machinery of these organisms to learn how they adapt and thrive in extreme environments. This new knowledge will predict how dinoflagellate-based ecosystems will respond to future climate change.
Transport systems that underpin nitrogen efficient maize. This project aims to define the nitrogen transport network involved in the uptake, storage and redistribution of inorganic nitrogen (nitrate and ammonium) over the developmental life cycle of maize. This information will provide novel insight into the genetic control of nitrogen use in maize and other cereal crops.
Nutrient transfer across symbiotic membranes in soybean. Legume plants interact with soil bacteria that fix nitrogen from the air to obtain nitrogen required for growth, reducing their use of fertilisers. Understanding how nutrients are exchanged between bacteria and legumes may improve the efficiency of this process. This would make legumes a more valuable component of sustainable agricultural systems.
Harnessing peptide hormone outputs to improve root nodulation’s efficacy. This project aims to transform our understanding of symbiotic nitrogen fixation in legume root nodules. Root nodulation sustainably fixes sizeable amounts of nitrogen to boost crop production worldwide yet its utilisation is waning in favour of using nitrogen fertilisers. The project applies cutting-edge tools to define how two hormone systems boost and limit nitrogen fixation, respectively. The project expects to reveal w ....Harnessing peptide hormone outputs to improve root nodulation’s efficacy. This project aims to transform our understanding of symbiotic nitrogen fixation in legume root nodules. Root nodulation sustainably fixes sizeable amounts of nitrogen to boost crop production worldwide yet its utilisation is waning in favour of using nitrogen fertilisers. The project applies cutting-edge tools to define how two hormone systems boost and limit nitrogen fixation, respectively. The project expects to reveal ways to reconfigure these hormone outputs to improve nodule number and the efficacy of nitrogen fixation. The findings will benefit agriculture by reducing the reliance on costly nitrogen fertilisers, thus mitigating the huge environmental damage they cause, and will provide more sustainable ways to ensure food security.Read moreRead less
Advanced cryobanking for recalcitrant-seeded Australian rainforest plants. This project aims to develop an interdisciplinary research alliance to enhance the efficiency of ecological restoration for recalcitrant Australian rainforest plant species. The project expects to provide fundamental knowledge to target two major impediments to cryostorage of recalcitrant-seeded native species: desiccation sensitivity with relatively large size, and active metabolism and precocious germination. These attr ....Advanced cryobanking for recalcitrant-seeded Australian rainforest plants. This project aims to develop an interdisciplinary research alliance to enhance the efficiency of ecological restoration for recalcitrant Australian rainforest plant species. The project expects to provide fundamental knowledge to target two major impediments to cryostorage of recalcitrant-seeded native species: desiccation sensitivity with relatively large size, and active metabolism and precocious germination. These attributes severely limit the time available for effective use of collected germplasm for long-term storage. A combination of biochemical, biophysical and molecular simulation approaches will be used to optimise cryopreservation of a wide range of endangered Australian rainforest species. This should provide significant benefits such as enabling conservation agencies to greatly enhance their ability to preserve the unique Australian rainforest flora, particularly given current threats due to habitat loss and global warming.Read moreRead less
