Improving production of essential oils from Australian trees. Production of essential oils from eucalypts and tea tree is an important rural industry in Australia but we are only a minor producer worldwide. Using new genetic discoveries about how plants make oils, this project will help the industry improve the yield and profitability from both eucalypts and tea tree and contribute new technologies to rural industry.
Molecular characterisation of the fungal disease defence response in tropical sandalwood (Santalum album). The tropical sandalwood industry in Australia is a highly profitable and expanding enterprise; however this cannot be taken for granted. Fungal diseases in tropical plantations are of increasing concern to growers and left unchecked could result in substantial economic loss and an unsustainable industry. This research seeks to understand the defence response of the tree in order to develop ....Molecular characterisation of the fungal disease defence response in tropical sandalwood (Santalum album). The tropical sandalwood industry in Australia is a highly profitable and expanding enterprise; however this cannot be taken for granted. Fungal diseases in tropical plantations are of increasing concern to growers and left unchecked could result in substantial economic loss and an unsustainable industry. This research seeks to understand the defence response of the tree in order to develop tools to combat fungal disease by rapid selection of highly resistant trees. Essential oil production is also linked to the defence response. Understanding this response as well as exploring chemical means of increasing both disease resistance and oil production will deliver a substantial economic benefit to the expanding tropical sandalwood industry.Read moreRead less
Re-evaluating the nature, origins and roles of terpenes in Eucalyptus. Terpenes give eucalypts their characteristic smell and mediate many interactions between trees and the environment. Studies of the genome show that eucalypts have more genes to make terpenes than any other plant. Our knowledge of the chemistry and roles of these terpenes is confined to leaves but almost half of the genes occur in roots, wood and bark and there is little idea what their roles are. This project will conduct the ....Re-evaluating the nature, origins and roles of terpenes in Eucalyptus.

Studies of the genome show that eucalypts have more genes to make terpenes than any other plant. Our knowledge of the chemistry and roles of these terpenes is confined to leaves but almost half of the genes occur in roots, wood and bark and there is little idea what their roles are. This project will conduct the first comprehensive study of terpenes in Eucalyptus to identify where and how they are made in the plant, how the major compounds evolved and how terpenes contribute to defence against insects, atmospheric emissions and the composition of soil.Read moreRead less

Gas chromatography: separating inseparables, identifiying unidentifiables. This project aims to provide researchers with an integrated capability for separation, isolation, and precise structural identification of volatile compounds. It expects to deliver a systematic solution using unprecedented, automated multidimensional gas chromatographic separation, isolating pure compounds for off-line characterisation using appropriate spectroscopic tools, for example nuclear magnetic resonance.

This project aims to provide researchers with an integrated capability for separation, isolation, and precise structural identification of volatile compounds. It expects to deliver a systematic solution using unprecedented, automated multidimensional gas chromatographic separation, isolating pure compounds for off-line characterisation using appropriate spectroscopic tools, for example nuclear magnetic resonance. This will provide significant benefits, such as permitting traceability of (bio)-synthetic pathways, better characterise chemical signalling in plants, accelerate identification of advanced intermediates required for total synthesis of alkaloids, improve detection of metabolites, and determine interactions between small allergens and proteins.Read moreRead less
Combating myrtle rust, a new disease threatening Australia’s unique flora. This project aims to reduce the impact of myrtle rust, an invasive plant disease. Myrtle rust is a globally significant biodiversity threat that is rapidly spreading to new regions. It affects many iconic native species as well as impacting commercial industries. The expected project outcomes are; a comprehensive understanding of the host genes involved in successful plant defence, and of the pathogen genes involved in th ....Combating myrtle rust, a new disease threatening Australia’s unique flora. This project aims to reduce the impact of myrtle rust, an invasive plant disease. Myrtle rust is a globally significant biodiversity threat that is rapidly spreading to new regions. It affects many iconic native species as well as impacting commercial industries. The expected project outcomes are; a comprehensive understanding of the host genes involved in successful plant defence, and of the pathogen genes involved in the establishment of parasitism. The project will employ new approaches that enhance the application of biotechnology to Australian biosecurity. Key expected benefits are; gene-specific tools for plant breeders and conservation land managers, and improved preparedness for the threat posed by new rust strains.Read moreRead less
New hyphenated chromatographic and spectroscopic methods for oil analysis. This project aims to use novel chemical separation methods combined with spectroscopy to identify useful markers in olive oil and essential oil to ensure purity, quality and authenticity, which are all ongoing issues in these industries in Australia and overseas.

This project aims to use novel chemical separation methods combined with spectroscopy to identify useful markers in olive oil and essential oil to ensure purity, quality and authenticity, which are all ongoing issues in these industries in Australia and overseas. The project plans to compare and integrate results of multidimensional gas chromatography combined with mass spectrometry and Fourier transform infrared analyses with data libraries to generate precise molecular identification. The outcome is expected to help monitor adulteration of oils and maintain the high quality standards of Australian produce.Read moreRead less
