Physiological and genetic mechanisms underlying tolerance of bread wheat to ion toxicities. Ion toxicities associated with acidic or alkaline soils and waterlogging cost about $190 million per year in lost yield in Western Australia alone. Soil ameliorants and agricultural measures to deal with these constraints are non-existent (B toxicity in alkaline sodic subsoils), non-effective (liming of acidic subsoils), expensive (drainage for waterlogged soils) or a combination of the above. This projec ....Physiological and genetic mechanisms underlying tolerance of bread wheat to ion toxicities. Ion toxicities associated with acidic or alkaline soils and waterlogging cost about $190 million per year in lost yield in Western Australia alone. Soil ameliorants and agricultural measures to deal with these constraints are non-existent (B toxicity in alkaline sodic subsoils), non-effective (liming of acidic subsoils), expensive (drainage for waterlogged soils) or a combination of the above. This project will characterise wheat genotypes for tolerance to ion toxicities and will lay the groundwork for deliberate breeding effort toward pyramiding tolerance to ion toxicities in elite germplasm.Read moreRead less
Physiological and molecular characterisation of salinity tolerance in chickpea. Chickpea is a grain legume often grown in rotation with cereal crops to enhance profitability and environmental sustainability of broadacre cropping systems in Australia, and elsewhere. Chickpea is sensitive to salinity, and thus can not be grown on soils affected even by mild salinity. Limited grain legume options currently exist for these soils. This project will improve salt tolerance in chickpea and thus allow it ....Physiological and molecular characterisation of salinity tolerance in chickpea. Chickpea is a grain legume often grown in rotation with cereal crops to enhance profitability and environmental sustainability of broadacre cropping systems in Australia, and elsewhere. Chickpea is sensitive to salinity, and thus can not be grown on soils affected even by mild salinity. Limited grain legume options currently exist for these soils. This project will improve salt tolerance in chickpea and thus allow it to be grown in areas too saline for current cultivars. The research contributes to the National Research Priority of 'An Environmentally Sustainable Australia', as new cultivars of chickpea with improved salt tolerance will enhance the profitability and sustainability of rotational cropping systems in Australia.Read moreRead less
Invesitgation of environmental staining and storage discolouration in Faba Bean. Faba beans are an important pulse crop in Australia. They are exported to the Middle East and Europe for human consumption where buff coloured beans are desired. A third of beans become discoloured in storage. These are downgraded to stock feed with a loss of $50 per ton to the grower. Currently little is known about the causes. Environmental factors and selected genotypes will be assessed to determine the potential ....Invesitgation of environmental staining and storage discolouration in Faba Bean. Faba beans are an important pulse crop in Australia. They are exported to the Middle East and Europe for human consumption where buff coloured beans are desired. A third of beans become discoloured in storage. These are downgraded to stock feed with a loss of $50 per ton to the grower. Currently little is known about the causes. Environmental factors and selected genotypes will be assessed to determine the potential causes of discoluration. Analytical techniques will ascertain the discolouration process and the compounds produced. The aim is to provide growers with information on management strategies and breeders of strain resistant genotypes.Read moreRead less
Plant Mitochondrial Signalling and Regulation. Plant energy production is essential for successful growth and development and is essential for processes such as seedling establishment and germination. This research project intends to expand our understanding of energy regulation within the plant using advanced technologies. Such studies can provide direct benefits to the Australian agriculture community through novel targets for genetic improvements.

Plant energy production is essential for successful growth and development and is essential for processes such as seedling establishment and germination. This research project intends to expand our understanding of energy regulation within the plant using advanced technologies. Such studies can provide direct benefits to the Australian agriculture community through novel targets for genetic improvements. The capacity to create such advantages is economically vital for the industry and the development of such expertise within Australia will ensure we are well placed to exploit future advances in agricultural improvements and provide the capacity to further generate novel biotechnological applications.Read moreRead less
Isolation and characterization of cell signalling systems that activate or suppress apoptosis in pathogenic and symbiotic fungal:plant interactions. The key roles of programmed cell death (PCD) in plant disease are becoming apparent. This project will test the hypotheses that successful colonisation by arbuscular mycorrhizae in plant roots requires the plant to up-regulate inhibitors of PCD; that susceptibility in plants to necrotrophic fungal pathogens requires triggering of PCD; and that resis ....Isolation and characterization of cell signalling systems that activate or suppress apoptosis in pathogenic and symbiotic fungal:plant interactions. The key roles of programmed cell death (PCD) in plant disease are becoming apparent. This project will test the hypotheses that successful colonisation by arbuscular mycorrhizae in plant roots requires the plant to up-regulate inhibitors of PCD; that susceptibility in plants to necrotrophic fungal pathogens requires triggering of PCD; and that resistance is the result of activation of inhibitors of PCD. This international project will have important implications biologically and economically for control of plant disease and symbiosis, will train early career researchers in an area of international expertise and will strengthen collaboration between the US and Australian research groupRead moreRead less
The regulation and role of dual targeted proteins in plant cells. Plant cells are the factories that provide the food we eat, the air we breath, play a critical role in a balanced environment and provide energy in a sustainable manner. The varied use of plants and plant products is underpinned by an understanding of biochemistry that takes place in plant cells. This proposal is aimed at understanding how some proteins function in more than one location in the multi-compartmentalised plant cell b ....The regulation and role of dual targeted proteins in plant cells. Plant cells are the factories that provide the food we eat, the air we breath, play a critical role in a balanced environment and provide energy in a sustainable manner. The varied use of plants and plant products is underpinned by an understanding of biochemistry that takes place in plant cells. This proposal is aimed at understanding how some proteins function in more than one location in the multi-compartmentalised plant cell biochemical factory. The knowledge that is generated from this research can be used to underpin innovative use of plants within Australia's plant based industries. Furthermore it provides a rich intellectual training environment for students and postdoctoral researchers.Read moreRead less

Joint Facility for Plant Genetic Analysis and Gene Discovery in WA. This project will extend collaboration between Murdoch and UWA by provision of advanced facilities for plant genetic analysis and gene discovery. This will be achieved by purchase of novel equipment for discovery and analysis of single nucleotide polymorphisms (SNPs - single base changes between individual plants) that mark differences in their properties, and by purchase of equipment to underpin gene discovery and analysis of ....Joint Facility for Plant Genetic Analysis and Gene Discovery in WA. This project will extend collaboration between Murdoch and UWA by provision of advanced facilities for plant genetic analysis and gene discovery. This will be achieved by purchase of novel equipment for discovery and analysis of single nucleotide polymorphisms (SNPs - single base changes between individual plants) that mark differences in their properties, and by purchase of equipment to underpin gene discovery and analysis of expression. Provision of this equipment will enable full use of plant growth facilities now under construction, lead to advanced technologies of plant genetic analysis, and discovery of new basic information on fundamental plant processes.Read moreRead less
