The response of mitochondria to oxidative stress in plants. Crops encounter many situations in their environment which place them under stress. Reactive oxygen molecules produced in these situations act as messengers to trigger defence mechanisms but also cause cellular damage. Mitochondria are the subcellular compartments involved in energy production and are essential for plant development and growth. However, they also have been implicated in the response of plants to stress and pathogen atta ....The response of mitochondria to oxidative stress in plants. Crops encounter many situations in their environment which place them under stress. Reactive oxygen molecules produced in these situations act as messengers to trigger defence mechanisms but also cause cellular damage. Mitochondria are the subcellular compartments involved in energy production and are essential for plant development and growth. However, they also have been implicated in the response of plants to stress and pathogen attack, and in production of reactive oxygen molecules. This proposal seeks to investigate how mitochondria are involved in these processes, focusing on the role of terminal oxidases. Potential outcomes include crops better able to cope with environmental stress.Read moreRead less
Practical application of gene silencing: is delivery of long double stranded ribonucleic acid (dsRNA) by plant cells efficient in conferring host resistance to parasitic nematodes? Nematode that attack plants cause $120 billion of crop losses worldwide. Chemicals used for their control are being phased out because of environmental concerns, and natural resistance is limited. The aim of this project is to use Australian IP to develop a new form of resistance to nematodes based on knowledge of th ....Practical application of gene silencing: is delivery of long double stranded ribonucleic acid (dsRNA) by plant cells efficient in conferring host resistance to parasitic nematodes? Nematode that attack plants cause $120 billion of crop losses worldwide. Chemicals used for their control are being phased out because of environmental concerns, and natural resistance is limited. The aim of this project is to use Australian IP to develop a new form of resistance to nematodes based on knowledge of the host-pathogen interactions. A successful outcome could contribute an additional 5-20% increase in crop yields (depending on the crop) through inherent resistance of crops to nematode pests. This would benefit rural communities and the national economy, and could also generate international royalties.Read moreRead less
Accelerated Domestication of Australian Grass Species Using Molecular Tools. The development of new food crops from the Australian flora will provide opportunities for new sustainable agricultural and food industries in Australia. The project targets the accelerated domestication of native species with lower tillage and fertiliser requirements, better water use efficiencies and increased salt, shade, frost and/or drought tolerances than the current introduced cereal and fodder crops. This will ....Accelerated Domestication of Australian Grass Species Using Molecular Tools. The development of new food crops from the Australian flora will provide opportunities for new sustainable agricultural and food industries in Australia. The project targets the accelerated domestication of native species with lower tillage and fertiliser requirements, better water use efficiencies and increased salt, shade, frost and/or drought tolerances than the current introduced cereal and fodder crops. This will directly benefit regional Australia. The technologies developed in the project will have wide application to accelerated domestication of other Australian plants (for agriculture and food production in Australia and internationally) and to plants found in other parts of the world.Read moreRead less

Improved Indian Mustard for sustainable biodiesel production. There is an urgent need to reduce Australia's dependency on fossil fuels and to improve the sustainability of the Australian farming sector. The on-farm production of biodiesel will reduce farm input costs, reduce farmer dependency on fluctuations in fossil fuel costs and reduce greenhouse gas emissions. Indian mustard is drought tolerant and produces inedible oil suitable for biodiesel production. The genetic improvement of Indian mu ....Improved Indian Mustard for sustainable biodiesel production. There is an urgent need to reduce Australia's dependency on fossil fuels and to improve the sustainability of the Australian farming sector. The on-farm production of biodiesel will reduce farm input costs, reduce farmer dependency on fluctuations in fossil fuel costs and reduce greenhouse gas emissions. Indian mustard is drought tolerant and produces inedible oil suitable for biodiesel production. The genetic improvement of Indian mustard will provide farmers with a viable crop for biodiesel production and its bio-fumigation properties make it an effective addition to the crop rotation. Useful by-products include a natural insecticide and, once the glucosinolates are removed, meal suitable for animal feed. Read moreRead less
Fingerprinting the soil microbial metagenome. The understanding of the impact of current farming systems on soil biology is in its infancy. Technology previously used to examine soil biology only investigates a very small percentage of all soil organisms. We will use an innovative new technology (DArT) to rapidly gain an overview of all soil microbial biodiversity. We will then evaluate the impact of agricultural practices on that biodiversity, firstly based on our long term trial site exhibiti ....Fingerprinting the soil microbial metagenome. The understanding of the impact of current farming systems on soil biology is in its infancy. Technology previously used to examine soil biology only investigates a very small percentage of all soil organisms. We will use an innovative new technology (DArT) to rapidly gain an overview of all soil microbial biodiversity. We will then evaluate the impact of agricultural practices on that biodiversity, firstly based on our long term trial site exhibiting common farming practices, and then by a broader regional survey. Our longer term goal is to find microbiological indicators of healthy soil through a vastly improved ability to determine a wide range of beneficial and disease organisms to identify sustainable farming practices.Read moreRead less
Improved seasonal rainfall prediction for grain growers using farm level data and novel modelling. Successful grain production, a key export commodity for Australia, depends heavily on reliable seasonal forecasts. However, the highly variable climate means that for Australia’s 25,000 grain growers current forecasts lack detail in space and time. Using a combination of fuzzy classification and artificial neural networks, this project will develop a locally detailed continuously updating data-driv ....Improved seasonal rainfall prediction for grain growers using farm level data and novel modelling. Successful grain production, a key export commodity for Australia, depends heavily on reliable seasonal forecasts. However, the highly variable climate means that for Australia’s 25,000 grain growers current forecasts lack detail in space and time. Using a combination of fuzzy classification and artificial neural networks, this project will develop a locally detailed continuously updating data-driven seasonal forecast system using high density climate data from the 17,000 Grain Growers Association members and climate drivers such as sea surface temperature from the Bureau of Meteorology. After validation against observed data, the forecasts will be delivered via a web-based portal to users.Read moreRead less

Australia faces the double challenge of improving the efficiency of its crop production while minimising the agricultural impact on its fragile biodiversity. Our project will meet this challenge by providing the technology for using natural biofertilisers in cereal crops. This will reduce our heavy reliance on chemical fertilisers - with associated soil loss, salinity and acidity, and high demand on scarce water resources - and significantly increase our crop yields. Our advances will help Australian farmers to reduce the costs and increase the productivity of our substantial export crops while improving their environmental sustainability.Read moreRead less
Genome Approaches to Investigate Metabolic Coordination in Plant Cells. Metabolism of C and N in legume nodules requires interaction between the symbiotic bacteria and plant organelles, particularly metabolism in plastids and mitochondria. Fixed N is assimilated through the de novo synthesis of purines in both plastids and mitochondria. However, each of the nine pathway enzymes is encoded by a single gene, indicating each protein is targeted to both organelles. Purine metabolism will provide ....Genome Approaches to Investigate Metabolic Coordination in Plant Cells. Metabolism of C and N in legume nodules requires interaction between the symbiotic bacteria and plant organelles, particularly metabolism in plastids and mitochondria. Fixed N is assimilated through the de novo synthesis of purines in both plastids and mitochondria. However, each of the nine pathway enzymes is encoded by a single gene, indicating each protein is targeted to both organelles. Purine metabolism will provide a model to assess the more general occurrence of dual-targeted proteins in plants. The aim is to identify and eventually exploit the signalling mechanism(s) that mediate communication between plastids and mitochondria.Read moreRead less
