A novel link between plant pathogen defence and DNA repair capability. Plants and plant-based industries are essential for the provision of food, clothing and building materials and underpin the economies of rural communities. Plant yield and quality and the biodiversity of natural systems are dramatically reduced by disease. The fundamental knowledge gained from our research will enable manipulation of the factors that enhance disease resistance resulting in a significant benefit to Australian ....A novel link between plant pathogen defence and DNA repair capability. Plants and plant-based industries are essential for the provision of food, clothing and building materials and underpin the economies of rural communities. Plant yield and quality and the biodiversity of natural systems are dramatically reduced by disease. The fundamental knowledge gained from our research will enable manipulation of the factors that enhance disease resistance resulting in a significant benefit to Australian agriculture and protection of our natural resources. The current reliance for disease control on chemicals that damage the environment will be reduced and our research will contribute directly to the provision of cheaper, simpler and more effective methods of control.

Characterisation of interacting genes that condition avirulence and resistance between Phytophthora pathogens and soybean. Plant pathogens from the genus Phytophthora cause severe crop losses in Australia and worldwide. Resistance in host plants is frequently overcome by mutation of avirulence genes in the pathogen to create virulent new races. We will clone and characterise genes from Phytophthora sojae that control virulence and avirulence, and isolate soybean genes whose products interact w ....Characterisation of interacting genes that condition avirulence and resistance between Phytophthora pathogens and soybean. Plant pathogens from the genus Phytophthora cause severe crop losses in Australia and worldwide. Resistance in host plants is frequently overcome by mutation of avirulence genes in the pathogen to create virulent new races. We will clone and characterise genes from Phytophthora sojae that control virulence and avirulence, and isolate soybean genes whose products interact with the Phytophthora gene products. An understanding of the molecular mechanisms than enable current plant varieties to recognise Phytophthora pathogens leading to resistance or susceptibility will assist the development of novel strategies for durable disease resistance in soybean and other crop plants.Read moreRead less

Bioengineering High Efficiency Solar Driven H2 Production. The project aims to bio-engineer high-efficiency microalgae cell-lines that can drive solar powered H2 production from water. It plans to do so by increasing proton and electron supply to the H2-producing hydrogenase. It builds on patented cell lines that have enhanced light capture efficiency and H2 production capabilities. The aim of this project is to increase the efficiency of the last stage of the process (three fold) in a major ste ....Bioengineering High Efficiency Solar Driven H2 Production.

It plans to do so by increasing proton and electron supply to the H2-producing hydrogenase. It builds on patented cell lines that have enhanced light capture efficiency and H2 production capabilities. The aim of this project is to increase the efficiency of the last stage of the process (three fold) in a major step in developing economic solar-fuel systems. National benefits include the development of advanced microalgae fuels systems to increase future fuel security, reduce CO2 emissions and assist with regional development.Read moreRead less
Efficient organelle transformation. Chloroplasts and mitochondria are the powerhouses of plant and animal cells. Ability to express introduced genes in these organelles has enormous biotechnological potential in agriculture and medicine, but practical development has been almost stalled for 15 years by very low transformation efficiency. Plastid transformation is today routine only in tobacco; and mitochondrial transformation has been achieved only in yeasts and algae. We have developed a soluti ....Efficient organelle transformation. Chloroplasts and mitochondria are the powerhouses of plant and animal cells. Ability to express introduced genes in these organelles has enormous biotechnological potential in agriculture and medicine, but practical development has been almost stalled for 15 years by very low transformation efficiency. Plastid transformation is today routine only in tobacco; and mitochondrial transformation has been achieved only in yeasts and algae. We have developed a solution, and achieved the key technical requirements for proof of concept. This collaboration between industry, government and university partners will deliver key Australian-owned IP, for environmentally-friendly plant biofactories, and for treatment of mitochondrial genetic disorders.Read moreRead less
Advanced solar powered hydrogen production systems based on green algal cells. This project aims to enhance the efficiency of solar powered hydrogen production from water and will facilitate the co-production of H2 and oil through microalgal biofuel systems. This frontier science project will therefore deliver a process with high solar conversion efficiency and will deliver multiple product streams increasing profitability.
