This project aims to determine the effects of beneficial soil fungi on wheat and rice grain quality for human nutrition using an innovative combination of physiological, molecular and agronomic techniques. The project expects to generate fundamental knowledge in sustainable agriculture, to improve grain quality and value. Expected outcomes of this project include enhanced understanding of the mechanisms underlying improved grain quality, and the capacity to use soil fungi to increase grain micronutrient concentrations and bioavailability. This should provide significant environmental and societal benefits, such as promotion of the sustainable use of agricultural soils and more nutritious grain products for human consumption.Read moreRead less
Effects of global climate change on marine phytoplankton: interactions between UV radiation and elevated atmospheric carbon dioxide levels. Global climate change is one of the most significant ecological challenges for the 21st Century. Phytoplankton contribute over 45% of the planet's annual net primary production and form the basis of most aquatic food chains. Conversely, some phytoplankton are toxic and cause problems in marine and fresh waters. Climate change can potentially disrupt aquatic ....Effects of global climate change on marine phytoplankton: interactions between UV radiation and elevated atmospheric carbon dioxide levels. Global climate change is one of the most significant ecological challenges for the 21st Century. Phytoplankton contribute over 45% of the planet's annual net primary production and form the basis of most aquatic food chains. Conversely, some phytoplankton are toxic and cause problems in marine and fresh waters. Climate change can potentially disrupt aquatic foodchains by its impact on primary production by phytoplankton or stimulating growth of potentially toxic forms. Our project will investigate the combined impact of increasing carbon dioxide and ultraviolet light on phytoplankton and thereby help climate modellers assess the impact of climate change on aquatic ecosystems and particularly on the nation's and the world's fisheries.Read moreRead less
Alternative Oxidase to Optimise Plant Growth and Stress Tolerance. Biomass accumulation in plants is the balance of CO2 fixed into carbohydrates through photosynthesis and carbohydrate burned (respired), ~ 50% of fixed CO2, to fuel growth. Plants possess energy conserving and non-conserving respiratory pathways. The alternative energy non-conserving pathway appears wasteful but is necessary for plant tolerance to adverse growth conditions. Our research has achieved modification of the alternativ ....Alternative Oxidase to Optimise Plant Growth and Stress Tolerance. Biomass accumulation in plants is the balance of CO2 fixed into carbohydrates through photosynthesis and carbohydrate burned (respired), ~ 50% of fixed CO2, to fuel growth. Plants possess energy conserving and non-conserving respiratory pathways. The alternative energy non-conserving pathway appears wasteful but is necessary for plant tolerance to adverse growth conditions. Our research has achieved modification of the alternative respiratory pathway that positively impacts plant growth. We will dissect the mechanism(s) of how the alternative respiratory pathway stimulates growth, from a molecular level to whole plant physiology, answering a long-standing question of the role of the alternative respiratory pathway in plant cell biology.Read moreRead less

How do plants cope with temporal variability in water and nutrients? Australia's climate and weather are temporally variable, yet we know little of how Australia's flora is affected by temporally variable vs constant supplies of water and nutrients. In addition, climate change will affect our flora by, among other things, increasing temporal variability in water and nutrient availability. This program of research will provide basic data on growth responses to variable vs. constant water and nu ....How do plants cope with temporal variability in water and nutrients? Australia's climate and weather are temporally variable, yet we know little of how Australia's flora is affected by temporally variable vs constant supplies of water and nutrients. In addition, climate change will affect our flora by, among other things, increasing temporal variability in water and nutrient availability. This program of research will provide basic data on growth responses to variable vs. constant water and nutrient availability. Hence, results will be directly applicable to predicting the effects of climate change on growth, species' distribution and community composition. This research will also improve our basic understanding of limitations to photosynthesis, transpiration and nutrient uptake/assimilation.Read moreRead less
Economics of carbon, nitrogen and water use in Acacia and Eucalyptus. Australia's flora is dominated by plants with sclerophyllous foliage, that is hard leaves that are tolerant of nutrient and/or water stress. Either nutrient and/or water stress are suggested as driving the evolution of sclerophylly and distribution of extant species. Mechanisms of tolerance to drought and nutrient stress differ, and these differences are reflected in patterns of nitrogen and carbon allocation and economics o ....Economics of carbon, nitrogen and water use in Acacia and Eucalyptus. Australia's flora is dominated by plants with sclerophyllous foliage, that is hard leaves that are tolerant of nutrient and/or water stress. Either nutrient and/or water stress are suggested as driving the evolution of sclerophylly and distribution of extant species. Mechanisms of tolerance to drought and nutrient stress differ, and these differences are reflected in patterns of nitrogen and carbon allocation and economics of nitrogen and water use in photosynthesis. The present study will use these differences in economics to distinguish between water- and nutrient-driven adaptations in a range of Acacia and Eucalyptus species from mesic to arid environments.Read moreRead less
Organisation and function of embedded oil glands in eucalypts. Some eucalypt leaves contain large quantities of essential oils, which have been extracted for commercial purposes for many years.
