Mechanisms of arsenic tolerance in plants: how do symbiotic arbuscular mycorrhizal (AM) fungi reduce uptake? Arsenic contamination of soil is a major problem caused by irrigation with contaminated ground-water, mining and application of pesticides. Plant uptake leads to entry into food chains, with severe consequences for crop growth and human health. This project will aid the search for mechanisms to reduce plant arsenic accumulation by exploring roles of beneficial plant-fungus symbioses in r ....Mechanisms of arsenic tolerance in plants: how do symbiotic arbuscular mycorrhizal (AM) fungi reduce uptake? Arsenic contamination of soil is a major problem caused by irrigation with contaminated ground-water, mining and application of pesticides. Plant uptake leads to entry into food chains, with severe consequences for crop growth and human health. This project will aid the search for mechanisms to reduce plant arsenic accumulation by exploring roles of beneficial plant-fungus symbioses in reducing uptake. Results will be relevant to most crop plants, because of the widespread occurrence of the symbioses. The project will enhance collaboration with China where arsenic toxicity is prevalent, provide education and training in an internationally recognised laboratory and enhance Australia's reputation for tackling soil contamination.Read moreRead less
Development and regulation of thermogenesis in thermoregulating flowers. Flowers of certain primitive plants produce enough heat to raise their temperatures up to 40 C above the air, and regulate it at a nearly constant level. Like warm-blooded mammals, the flowers increase heat production as environmental temperature falls. However, they thermoregulate on a cellular level, unlike mammals with their complex nervous system. We aim to elucidate the mechanisms involved in regulation of heat-prod ....Development and regulation of thermogenesis in thermoregulating flowers. Flowers of certain primitive plants produce enough heat to raise their temperatures up to 40 C above the air, and regulate it at a nearly constant level. Like warm-blooded mammals, the flowers increase heat production as environmental temperature falls. However, they thermoregulate on a cellular level, unlike mammals with their complex nervous system. We aim to elucidate the mechanisms involved in regulation of heat-production, with molecular, biochemical and stable isotope techniques. We will investigate spatial and temporal patterns of gene expression and activity of putative regulatory enzymes. The results will have implications for human physiology and agriculture.Read moreRead less
Calcium compartmentation in leaves: testing an integrated model of water and calcium transport with cell specific functional genomics. Calcium is a vital nutrient to animals and humans and its storage in vegetation is important for its accessibility. We believe this storage is linked to water flow in the leaf by a novel mechanism. This project will provide fundamental understanding of the cell type-specific processes involved in calcium storage and water flow in plants. High calibre PhD and Hono ....Calcium compartmentation in leaves: testing an integrated model of water and calcium transport with cell specific functional genomics.

This project will provide fundamental understanding of the cell type-specific processes involved in calcium storage and water flow in plants. High calibre PhD and Honours students will be educated to maintain the momentum of international excellence within Australia in the field of plant nutrient relations. The increase in understanding will allow future work to improve calcium availability and water use by plants to the benefit of agricultural productivity and quality of life.Read moreRead less
Multifunctional channels as key components of biotrophic interfaces in legumes. In legumes there are two types of membrane interfaces between different genomes that are critical for growth and yield (nitrogen fixation and seed loading), which require cell-signalling pathways to control nutrient exchange. The membranes of these interfaces contain specialised proteins that form multifunctional channels through which water, uncharged molecules and electrolytes move. These channels are likely to be ....Multifunctional channels as key components of biotrophic interfaces in legumes. In legumes there are two types of membrane interfaces between different genomes that are critical for growth and yield (nitrogen fixation and seed loading), which require cell-signalling pathways to control nutrient exchange. The membranes of these interfaces contain specialised proteins that form multifunctional channels through which water, uncharged molecules and electrolytes move. These channels are likely to be responsible for supporting the bulk of transported nutrients and in controlling their exchange. We aim to discover how these channels function in nitrogen fixation and seed loading with a view to developing new technologies that may enhance crop productivity.Read moreRead less

The Australian Agrifood sector will benefit significantly from the establishment of functional genomics platform technologies, such as metabolomics, that underpin 'Systems Biology'; a new branch of biology that attempts to discover and understand biological properties that emerge from the interactions of many system elements. Australian agriculture will benefit through the development of techniques to improve both yield and quality through minimising the effects of abiotic and biotic stresses, and a reduced dependence on inputs (eg fertilisers) leading to environmentally sustainable production systems. Ultimately this will result in enhanced food quality and analytical methods to monitor quality and safety characteristics of food.Read moreRead less
