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

The project will upgrade and expand the Newcastle Plant Growth Facility. The upgrades will improve glasshouse environments for the production of high quality plant material. This outcome will be achieved through increasing solar transmittance and more effective temperature control. Expansion will address unmet demand for standard and PC2 plant growth space. Together the infrastructure additions will enhance productivity and excellence of core areas of plant biology research at Newcastle in nutrient transport, cell development as well as environment management and rehabilitation . In addition, they will underpin new collaborative initiatives at the interfaces between plant biology with transgenic delivery of reproductive vaccines and phytoremediation.Read moreRead less
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

The technique of DNA sequencing (or 'reading' the lines of the four repeating letters that make up the genetic code) illustrates how technological developments have become the main drivers in exploring the roles of genetic factors across a spectrum of research activities. Funding provided through this ARC grant will allow the purchase of the latest DNA sequencing platform, the Illumina Solexa, as well as equipment that will be used to understand the biological function of the DNA sequencing results that are obtained. The equipment will allow Australian researchers to compete on an equal footing with the international leaders in understanding the roles played by genes in plants, microorganisms, animals and humans.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

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.

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

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

Symbiotic transport proteins in legumes. Some plants form a symbiosis with soil bacteria (rhizobia) that convert atmospheric nitrogen to ammonia which is then supplied to the plant. This enables legumes to grow without application of nitrogen-based fertilizer, avoiding environmental problems such as run-off and land degradation, thereby contributing to sustainable agriculture practise.

Some plants form a symbiosis with soil bacteria (rhizobia) that convert atmospheric nitrogen to ammonia which is then supplied to the plant. This enables legumes to grow without application of nitrogen-based fertilizer, avoiding environmental problems such as run-off and land degradation, thereby contributing to sustainable agriculture practise. We will investigate the interactions between plant and rhizobia, focusing on identifying genes and proteins which govern nutrient exchange between the partners and development of the special structures in the roots that house the bacteria. Subsequent manipulation of these genes and proteins may allow us to identify control points and enhance nitrogen fixation.
