Fungal Glucanase Genes for Engineering Disease Resistance in Plants. Plants can be engineered for resistance to fungal diseases by transformation with recombinant genes encoding chitinase or glucanase. Although fungi are prolific producers of glucanases, with some species producing novel forms, they have been unexplored as a source of useful glucanases. This project will isolate glucanase-producing fungi from soil, screen them for antifungal activity, and clone the glucanase genes from one or m ....Fungal Glucanase Genes for Engineering Disease Resistance in Plants. Plants can be engineered for resistance to fungal diseases by transformation with recombinant genes encoding chitinase or glucanase. Although fungi are prolific producers of glucanases, with some species producing novel forms, they have been unexplored as a source of useful glucanases. This project will isolate glucanase-producing fungi from soil, screen them for antifungal activity, and clone the glucanase genes from one or more isolates. In view of the high degree of biodiversity in WA soils, we have a high expectation of finding novel glucanases which will be useful for engineering disease resistance in plants, or for other industrial processes.Read moreRead less
Defining the evolutionary processes of resistance to the new mode of action herbicide, pyroxasulfone. The sustainability of the Australin grains industry is threatened by the continuing evolution and widespread expansion of herbicide resistant weed populations across the crop production regions. The resulting loss in herbicide efficacy is forcing producers away from the environmentally friendly practices of stubble retention and reduced tillage in an effort to control herbicide resistant weed po ....Defining the evolutionary processes of resistance to the new mode of action herbicide, pyroxasulfone. The sustainability of the Australin grains industry is threatened by the continuing evolution and widespread expansion of herbicide resistant weed populations across the crop production regions. The resulting loss in herbicide efficacy is forcing producers away from the environmentally friendly practices of stubble retention and reduced tillage in an effort to control herbicide resistant weed populations. This research is aimed at conserving a novel mode of action herbicide with efficacy on resistant Lolium rigidum populations. The success of this project will inevitably lead the pesticide industry to adopt this approach for future product development. Read moreRead less
Expression profiling of giant cells induced in host plant roots by root-knot nematodes. Root-knot nematodes cause crop losses of over $400 million per annum in Australia. Control by toxic chemical nematicodes is expensive and can pollute groundwater. Benefits from this research for the Australian community are: (i) it will ensure that Australian researchers stay at the forefront of research in plant nematology, (ii) it provides significant local and international linkages that will stimulate res ....Expression profiling of giant cells induced in host plant roots by root-knot nematodes.

Benefits from this research for the Australian community are: (i) it will ensure that Australian researchers stay at the forefront of research in plant nematology, (ii) it provides significant local and international linkages that will stimulate research outputs, and (iii) new knowledge will be generated on how plants respond to attack by nematodes - this will generate new intellectual property, leading to better control methods and reduced costs that will support rural communities, and reduce environmental pollution.Read moreRead less

Summary
The Insect-Plant Chemical Ecology Network (IPCEN). We bring together plant molecular biology, entomology and analytical chemistry to transform three leading fields of Australian research into an advanced science with far reaching capabilities in innovative research and applied outcomes. Expertise studying the biochemical pathways that produce specific plant compounds and expertise in insect recognition and response to these chemicals will be brought together. This will lead to new research outco ....The Insect-Plant Chemical Ecology Network (IPCEN). We bring together plant molecular biology, entomology and analytical chemistry to transform three leading fields of Australian research into an advanced science with far reaching capabilities in innovative research and applied outcomes. Expertise studying the biochemical pathways that produce specific plant compounds and expertise in insect recognition and response to these chemicals will be brought together. This will lead to new research outcomes and solutions to problems in agriculture, horticulture, forestry and protection of Australia's native flora. Researchers are struggling to create these links, constrained by disciplinary boundaries and geographical isolation. Key industries and researchers already support this proposal.Read moreRead less
Gene identification and genetic marker analysis of herbicide resistance in Lolium rigidum. Herbicide resistance threatens the vibrant, export-focused Australian cropping industry and environmental sustainability. The Australian herbicide resistance problem is far greater than elsewhere in the world.

Herbicide resistance threatens the vibrant, export-focused Australian cropping industry and environmental sustainability. The Australian herbicide resistance problem is far greater than elsewhere in the world. Herbicide resistance must be avoided, managed and reversed to ensure profitable agriculture and an environmentally sustainable landscape. This research will contribute to the national wealth through helping ensure the profitability of vital Australian export agricultural industries and the sustainability of the soil/land resource. This proposal will ensure that Australia leads international herbicide resistance research and will enable the capture of intellectual property and commercial opportunities. Read moreRead less
Life hanging on a thread; disrupting the structure and function of lepidopteran silking behaviour. The production and use of silk by many invertebrates is vital for their survival. We develop a means of visualising and understanding the role of silking behaviour as a survival mechanism for Helicoverpa larvae (a key world-wide pest) with a view to disrupting silking. This novel project allows us to understand not just where larvae go but what they do along the way. The project outcomes will have ....Life hanging on a thread; disrupting the structure and function of lepidopteran silking behaviour. The production and use of silk by many invertebrates is vital for their survival. We develop a means of visualising and understanding the role of silking behaviour as a survival mechanism for Helicoverpa larvae (a key world-wide pest) with a view to disrupting silking. This novel project allows us to understand not just where larvae go but what they do along the way. The project outcomes will have wide application to the study and control of lepidopteran pests in natural and agricultural ecosystems and is of interest to applied and fundamental projects associated with insect pest control, behaviour and ecology.Read moreRead less
A new approach to control of plant parasitic nematodes. Plant parasitic nematodes are the fourth most important plant pathogens worldwide. The aim of this project is to develop ?proof-of-concept? of a new strategy for nematode control, based on a synthetic ?cell death? resistance gene, in which tight specificity of expression of the resistance gene is provided using two gene promoters. The work focusses on finding the best combination of promoters which are switched on by infection of plants w ....A new approach to control of plant parasitic nematodes. Plant parasitic nematodes are the fourth most important plant pathogens worldwide. The aim of this project is to develop ?proof-of-concept? of a new strategy for nematode control, based on a synthetic ?cell death? resistance gene, in which tight specificity of expression of the resistance gene is provided using two gene promoters. The work focusses on finding the best combination of promoters which are switched on by infection of plants with nematodes. It is based on an Australian patent which has wide applicability in plant biotechnology. Nematode control will benefit horticultural and broadacre farming by reducing pathogen losses and improving quality.Read moreRead less
