Enhancing native seed performance for minesite restoration and biodiversity conservation. The knowledge and practical outcomes generated from this project will facilitate more effective restoration of degraded native ecosystems through the return of a wider range of key understorey plant taxa and more efficient use of seed supplies. Availability of a broader suite of species will increase biodiversity, improve ecosystem resilience to change, and help in the conservation and recovery of nationall ....Enhancing native seed performance for minesite restoration and biodiversity conservation. The knowledge and practical outcomes generated from this project will facilitate more effective restoration of degraded native ecosystems through the return of a wider range of key understorey plant taxa and more efficient use of seed supplies. Availability of a broader suite of species will increase biodiversity, improve ecosystem resilience to change, and help in the conservation and recovery of nationally threatened taxa. By increasing the range of species with horticultural potential available for commercial propagation, it will also reduce the harvest of wild flowers. More efficient production and use of seed stocks will reduce the pressure on limited seed resources from seed harvesting.Read moreRead less
Novel oxygen sensing tools for monitoring the effects of dredging on Australian seagrass communities. Seagrass meadows sustain marine biodiversity and the fishing industries on Australian coasts. Dredging of ports and shipping channels is contributing to their rapid global decline. The project will use state-of-the-art technologies in bio-optics and genomics to create a toolkit for seagrass managers to make informed decisions to safeguard seagrass meadows.
Strigolactone, a new plant hormone: its regulation, role and potential for plant improvement. This Project will investigate a new plant hormone, one of only 10 or so discovered to date in plants. This hormone regulates shoot number, water and nutrient uptake and the ability of shoots to generate roots and develop wood. The Project will produce genetic tools and describe new processes for applications in sustainable plant improvement.
Unsaturation of vapour pressure inside leaves: fundamental, but unknown. This project aims to determine when and to what extent the air inside leaves becomes unsaturated with water vapour. All current interpretation and modelling of leaf gas exchange assumes saturation under all circumstances. Compelling evidence has been obtained that suggests this is not true under moderate air vapour pressure deficits. A novel technique will be employed to assess the water vapour concentration of the air insi ....Unsaturation of vapour pressure inside leaves: fundamental, but unknown. This project aims to determine when and to what extent the air inside leaves becomes unsaturated with water vapour. All current interpretation and modelling of leaf gas exchange assumes saturation under all circumstances. Compelling evidence has been obtained that suggests this is not true under moderate air vapour pressure deficits. A novel technique will be employed to assess the water vapour concentration of the air inside leaves based on stable isotope analysis of carbon dioxide and water vapour exchanged between leaves and air. The project is expected to provide fundamental knowledge about how stomata regulate photosynthesis and water use, with significant implications for modelling vegetation function and for improving the performance of crop plants.Read moreRead less
Top-down rehydration: role of multiple water sources in mangrove function. This project aims to combine cutting-edge analytical and imaging techniques to assess contributions of atmospheric water sources to shoot-water balances, identify leaf traits associated with top-down rehydration, and determine the relative importance of different sources of water used by mangroves in maintenance of photosynthetic carbon assimilation along natural gradients in salinity and aridity. The capacity of shoots ....Top-down rehydration: role of multiple water sources in mangrove function. This project aims to combine cutting-edge analytical and imaging techniques to assess contributions of atmospheric water sources to shoot-water balances, identify leaf traits associated with top-down rehydration, and determine the relative importance of different sources of water used by mangroves in maintenance of photosynthetic carbon assimilation along natural gradients in salinity and aridity. The capacity of shoots to absorb atmospheric water could profoundly affect the diversity, survival and productivity of mangroves where high soil salinity limits water uptake by roots, particularly during hot, dry conditions.Read moreRead less
Interactive effects of salinity and nutrients: linking physiological processes with patterns in mangrove forest productivity. The proposed research will provide insight into physiological mechanisms that underpin mangrove productivity along salinity and aridity gradients, and determine how these factors affect plant responses to nutrient enrichment. Plant traits that increase salt and drought tolerance will be identified, thereby assisting development of plant varieties suited to Australian cond ....Interactive effects of salinity and nutrients: linking physiological processes with patterns in mangrove forest productivity. The proposed research will provide insight into physiological mechanisms that underpin mangrove productivity along salinity and aridity gradients, and determine how these factors affect plant responses to nutrient enrichment. Plant traits that increase salt and drought tolerance will be identified, thereby assisting development of plant varieties suited to Australian conditions. The results will also contribute to development of process-based models to better manage mangrove resources with climate change and increasing nutrient influx from urban or agricultural activities. Such models are essential for managing mangrove productivity for sustainable fisheries, and protecting the ecological well being of the coastal zone.Read moreRead less

Summary
Is plant organisation the fountain of eternal youth? The decline in performance at advanced ages, senescence, affects life quality, lifespan and productivity. It is believed that this phenomenon is universal, including all species from microbes to humans. Yet, some plants do not exhibit senescence. This project will identify the mechanisms that enable plants to escape senescence. Using a unique global demographic database, the project will determine whether, how and when senescence has evolved a ....Is plant organisation the fountain of eternal youth? The decline in performance at advanced ages, senescence, affects life quality, lifespan and productivity. It is believed that this phenomenon is universal, including all species from microbes to humans. Yet, some plants do not exhibit senescence. This project will identify the mechanisms that enable plants to escape senescence. Using a unique global demographic database, the project will determine whether, how and when senescence has evolved across 850 plant species. It will also experimentally test how drought, nutrients and resprouting affect senescence in two mallee Eucalyptus species in the Simpson Desert. This research will provide new insights into the evolution of senescence and will elucidate how some plants escape a supposedly unavoidable fate.Read moreRead less
How do sunflowers make protein drugs in their seeds? We recently discovered in sunflower the origin of a small protein ring that chemists have used for a decade to base designed drugs upon. This project aims to know how sunflowers make it so we may manipulate other plants to manufacture ring-based drugs.
The new plant hormone controlling shoot branching. This project will create genetic tools and knowledge on the control of a new plant growth hormone that affects a diverse number of plant properties. These important traits include shoot number, water and nutrient uptake, wood production, the ability to generate roots and the ability to stimulate particular potentially devastating parasitic weeds.

Initially I will use plants to create engineered cyclotides that incorporate peptides with proven therapeutic activity against cancer and multiple sclerosis. Successful production of therapeutic proteins in plants will benefit Australians by making treatments for these and other diseases more accessible. It also has the potential for a major economic benefit from the sales of Australian-based drugs. This proposal will also provide outstanding research training for graduate students in multidisciplinary methods that constitute state-of the-art structural and plant molecular biology.Read moreRead less
