Plant : fungal symbioses in Australian forests - new perspectives using laser microdissection. Ericaceae are important components of the Australian flora in many habitats, including forests and fragile alpine regions that are significant to Australia's cultural and natural heritage, and several species are considered threatened. This project addresses the fundamental question of whether networks of symbiotic fungal mycelia act as below-ground bridges between Ericaceae plants and tree roots.

Ericaceae are important components of the Australian flora in many habitats, including forests and fragile alpine regions that are significant to Australia's cultural and natural heritage, and several species are considered threatened. This project addresses the fundamental question of whether networks of symbiotic fungal mycelia act as below-ground bridges between Ericaceae plants and tree roots. If demonstrated, this would alter current views of carbon and nutrient cycling in Australian forests and provide the basis for better informed decisions for the sustainable management of Australian forest resources. This is particularly important in the context of carbon sequestration and future climate change.Read moreRead less
Understanding fungal diversity and functioning in forest soils using molecular and stable isotope approaches. The project aims to investigate fungal community structure and functioning in forest soils using novel molecular, stable isotope and physiological approaches. This will provide new insights into the linkage between diversity and functioning in forest soil fungal communities and the importance of these organisms in ecosystem processes. In addition, this pioneering research will facilitate ....Understanding fungal diversity and functioning in forest soils using molecular and stable isotope approaches. The project aims to investigate fungal community structure and functioning in forest soils using novel molecular, stable isotope and physiological approaches. This will provide new insights into the linkage between diversity and functioning in forest soil fungal communities and the importance of these organisms in ecosystem processes. In addition, this pioneering research will facilitate development and refinement of methodologies that will pave the way for future investigations of fungal ecology. The on-going collaboration will produce high quality joint publications and provide significant opportunities for early career researchers to gain international experience in a dynamic research environment.Read moreRead less

Summary
The genetic basis for bioactivity in the traditional medicine plants of Australia. A plant species that produces a bioactive compound usually produce the compound in very small amounts. To allow for marketable levels of production of the bioactive compound, numerous amounts of plants would need to be removed from the environment. This not only removes the limited supply of possibly rare types of plants from the environment but also denies the use of this plant by traditional people. Locating and ....The genetic basis for bioactivity in the traditional medicine plants of Australia. A plant species that produces a bioactive compound usually produce the compound in very small amounts. To allow for marketable levels of production of the bioactive compound, numerous amounts of plants would need to be removed from the environment. This not only removes the limited supply of possibly rare types of plants from the environment but also denies the use of this plant by traditional people. Locating and using the genes responsible for producing these bioactive compounds will allow their sustainable biosynthesis.Read moreRead less
Exploiting microbial metabolites to understand fungal biology. The project aims to investigate the principles of hyphal growth in fungi, by studying the mechanisms of action of a bacteria-derived compound that inhibits hyphae. Changing cell shape between yeast and hyphae is a prototype developmental switch enabling fungi to escape stressful environments, while hyphal invasion promotes fungal infections of animals and plants that endanger food security and biodiversity. By using interdisciplinary ....Exploiting microbial metabolites to understand fungal biology. The project aims to investigate the principles of hyphal growth in fungi, by studying the mechanisms of action of a bacteria-derived compound that inhibits hyphae. Changing cell shape between yeast and hyphae is a prototype developmental switch enabling fungi to escape stressful environments, while hyphal invasion promotes fungal infections of animals and plants that endanger food security and biodiversity. By using interdisciplinary approaches of microbiology and chemistry, the expected outcomes are to generate deep knowledge of an important microbial process and how it could be modulated, characterise a new bacterial compound and build research capacity at the nexus of biology and chemistry to benefit discoveries in academia and industry.Read moreRead less
Closing the carbon cycle: an ecological understanding of wood decay. The project aims to understand the controls on the return of carbon to the atmosphere within forests, especially focusing on this problem from a microbial perspective. Microbial dynamics and wood decay are crucially important for the global carbon cycle. What the field is lacking is a trait-based ecology of wood decomposers. The project plans to examine the interactions among fungal and oomycete endophytes and decomposers throu ....Closing the carbon cycle: an ecological understanding of wood decay. The project aims to understand the controls on the return of carbon to the atmosphere within forests, especially focusing on this problem from a microbial perspective. Microbial dynamics and wood decay are crucially important for the global carbon cycle. What the field is lacking is a trait-based ecology of wood decomposers. The project plans to examine the interactions among fungal and oomycete endophytes and decomposers through a series of experiments. The expected outcome of this project is a clear understanding of the role of traits in wood decomposer communities, especially their influence on priority effects, competitive hierarchies, and the resultant wood decay rate.Read moreRead less
