The dynamics of organic matter turnover in soils to improve the productivity of Australia's agricultural industries. Two recent national reports on the soils issues facing Australian agriculture (Reeves et al, 1997; CSIRO, 2000) concluded that soil structural degradation remains, after salinisation, our major threat to the sustainability of agricultural production. This research will provide fundamental understanding of how the dynamics of organic matter turnover benefit aggregate formation and ....The dynamics of organic matter turnover in soils to improve the productivity of Australia's agricultural industries. Two recent national reports on the soils issues facing Australian agriculture (Reeves et al, 1997; CSIRO, 2000) concluded that soil structural degradation remains, after salinisation, our major threat to the sustainability of agricultural production. This research will provide fundamental understanding of how the dynamics of organic matter turnover benefit aggregate formation and stability. This will advance the understanding of organic matter from simply considering the quantity of carbon present, to one of predicting the short- and long-term benefits to soil structure. This approach is innovative in the study of soil health, and has the potential to greatly advance the development of conservation farming systems.Read moreRead less

This project aims to provide proof-of-concept for the rapid production of plant-made vaccines of high strategic value to the poultry industry. Plant-made AI vaccines would help safeguard primary industries in Australia from exotic influenza strains and shield rural communities from the impact of stock losses. This collaboration will also contribute to the Molecular Farming industry by ensuring that Australian interests are considered as this frontier technology tackles the challenges of turning academic research into marketable products. The key features of an oral plant-made AI vaccine, including rapid and non-egg based production, also make this an attractive technology for the future development of swine and human influenza vaccines.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
Synthesis of carbohydrate antigens and production of monoclonal antibodies for biotechnological applications. Plant proteoglycans are widely used in the Australian agrifood industry as emulsifiers and thickening agents. In plants, they have been implicated in critical roles such as embryogenesis, development and programmed cell death; processes that ultimately determine agricultural production. However studies into plant proteoglycans are limited by a lack of specific reagents to probe their cel ....Synthesis of carbohydrate antigens and production of monoclonal antibodies for biotechnological applications. Plant proteoglycans are widely used in the Australian agrifood industry as emulsifiers and thickening agents. In plants, they have been implicated in critical roles such as embryogenesis, development and programmed cell death; processes that ultimately determine agricultural production. However studies into plant proteoglycans are limited by a lack of specific reagents to probe their cellular function. We propose to develop a series of monoclonal antibodies that can be used to study the structure and function of plant proteoglycans. These antibodies will have broad uses in basic and strategic research programs and will accelerate the commercial development of plant proteoglycans for use in the food industry.Read moreRead less
Plant Cells for Improved Oral Delivery of Vaccines. The pharmaceutical industry is ever assessing methods of improved delivery of their valuable vaccines, pharmaceuticals and nutraceuticals. The oral route increases ease of delivery, is less expensive, and has increased patient compliance. It may also allow vaccination of free-ranging animal populations that may otherwise go untreated. Optimizing oral delivery of plant-made, valuable proteins will therefore have broad ramifications to animal and ....Plant Cells for Improved Oral Delivery of Vaccines. The pharmaceutical industry is ever assessing methods of improved delivery of their valuable vaccines, pharmaceuticals and nutraceuticals. The oral route increases ease of delivery, is less expensive, and has increased patient compliance. It may also allow vaccination of free-ranging animal populations that may otherwise go untreated. Optimizing oral delivery of plant-made, valuable proteins will therefore have broad ramifications to animal and human health industries, enhancing use of existing valuable compounds and creating opportunities for new compounds and user groups including wild and domesticated animals.Read moreRead less
The role of mycorrhizal fungi in nutrient supply and habitat specificity of the rare underground orchid (Rhizanthella gardneri). The underground orchid (Rhizanthella gardneri) is an extremely rare achlorophyllous myco-heterotroph that shares a mycorrhizal fungus with broom bush (Melaleuca uncinata). This project will investigate habitat requirements for R. gardneri and assess the orchid dependence on M. uncinata for carbon and nutrient supply. We will measure magnitude and timing of nutrient a ....The role of mycorrhizal fungi in nutrient supply and habitat specificity of the rare underground orchid (Rhizanthella gardneri). The underground orchid (Rhizanthella gardneri) is an extremely rare achlorophyllous myco-heterotroph that shares a mycorrhizal fungus with broom bush (Melaleuca uncinata). This project will investigate habitat requirements for R. gardneri and assess the orchid dependence on M. uncinata for carbon and nutrient supply. We will measure magnitude and timing of nutrient and carbon transfers between M. uncinata roots, fungal hyphae and R. gardneri using stable isotope techniques. This project will provide knowledge essential for conserving the underground orchid, a unique Australian plant, and other critically endangered orchids.Read moreRead less
