The Centre will create a new generation of leaders in the implementation of advanced gene and field technologies for the benefit of the Australian agriculture industry. We will build the workforce and foundations that will drive translation of breakthroughs in advanced breeding, phenotyping and genetic technologies into higher-yielding crops. This will increase productivity across the sector and create new markets. Our technical training programs for graduates, trainees and industry will interface with best evidence-based practices in the wider socio-economic, regulatory and environmental contexts. Coupled with community and stakeholder engagement, the Centre will redefine and secure Australia’s future in agriculture. Read moreRead less
Is physiological flexibility of forest trees constrained by home climate in a rapidly warming world? The projected average Australian climate warming of 3 degrees celsius by 2070 represents a shift in climate equivalent to moving 900 km from Sydney to Brisbane. As forest trees cannot migrate fast enough to avoid these unprecedented increases in temperature, the resiliency of Australian forests to climate warming will depend on their capacity to physiologically adjust to higher temperatures. But, ....Is physiological flexibility of forest trees constrained by home climate in a rapidly warming world? The projected average Australian climate warming of 3 degrees celsius by 2070 represents a shift in climate equivalent to moving 900 km from Sydney to Brisbane. As forest trees cannot migrate fast enough to avoid these unprecedented increases in temperature, the resiliency of Australian forests to climate warming will depend on their capacity to physiologically adjust to higher temperatures. But, can forest trees successfully adjust to new climates in their current locations? This project plans to determine how thermal acclimation influences leaf and tree carbon exchange, and whether this depends upon a tree’s “home” climate. These knowledge gaps limit our ability to predict the future of our forests and consequences for carbon cycling in a warmer world.Read moreRead less
Understanding leaf water isotope composition. This project aims to quantify variation in leaf water isotopes and develop mechanistic models for paleoclimatologists and plant scientists to constrain global carbon cycles. Leaf water stable isotopes influence the isotope compositions of atmospheric oxygen, carbon dioxide and water vapour, and impart an evaporative signal on the isotope composition of plant organic material. These isotope signals have been used to constrain global carbon and water c ....Understanding leaf water isotope composition. This project aims to quantify variation in leaf water isotopes and develop mechanistic models for paleoclimatologists and plant scientists to constrain global carbon cycles. Leaf water stable isotopes influence the isotope compositions of atmospheric oxygen, carbon dioxide and water vapour, and impart an evaporative signal on the isotope composition of plant organic material. These isotope signals have been used to constrain global carbon and water cycles and reconstruct past climates. This project aims to quantify variation in leaf water isotopes and develop mechanistic models for use by paleoclimatologists, plant scientists and to constrain global carbon cycles and develop accurate models of leaf water isotopes to reduce uncertainty in climate models.Read moreRead less

Summary
Shifting rainfall from spring to autumn: tree growth and water use under climate change. Managing Australia's variable water resources is imperative. When the timing of rain shifts, with decreases in spring and increases in autumn, is water use in plants similar to plants which experience only a spring drought? Understanding plant water use as the timing of rain shifts will help us manage Australia's water more effectively.

Summary
Water and carbon stable isotope exchange between the biosphere and atmosphere. Understanding how climatic factors affect ecosystem carbon dioxide and water fluxes is essential for better climate models and managements strategies. This project will use novel isotope laser spectroscopy to measure the oxygen isotope of transpired water and that of the atmosphere to examine carbon dioxide and water at both the leaf and ecosystem scale.
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
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
