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.

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

Phytosphere: new facilities for controlled manipulation of effects of climate change & airborne pollutants on disease epidemiology & plant performance. Western Australia is home to a range of world-leading plant science research groups. Establishing a world-class multi-purpose phytosphere facility in WA will enable these groups to remain at the forefront of their research fields and continue to attract high-profile international scientists and students. Such a facility will result in significant ....Phytosphere: new facilities for controlled manipulation of effects of climate change & airborne pollutants on disease epidemiology & plant performance. Western Australia is home to a range of world-leading plant science research groups. Establishing a world-class multi-purpose phytosphere facility in WA will enable these groups to remain at the forefront of their research fields and continue to attract high-profile international scientists and students. Such a facility will result in significant advancement of our understanding of the impact of climate change on plants through biotic stresses (e.g., disease epidemiology, plant-pathogen interactions) and in interaction with abiotic variables (e.g., CO2 concentrations, temperature, light intensity, humidity, moisture stress, airborne pollutants such as SO2), and allow crop yield optimisation in future environments.Read moreRead less
Combinatorial controlled gene expression delivering crops resistant to nematodes. Root-knot nematodes cause US$130 billion crop losses worldwide pa, and at least AUS$ 450 pa in Australia. Current control methods involve fumigation, chemicals (mainly carbamates and organophosphates), natural plant resistance and biological control. The fumigants (eg methyl bromide) are being phased out because they damage the ozone layer, most of the non-fumigants are being banned because of environmental damag ....Combinatorial controlled gene expression delivering crops resistant to nematodes. Root-knot nematodes cause US$130 billion crop losses worldwide pa, and at least AUS$ 450 pa in Australia. Current control methods involve fumigation, chemicals (mainly carbamates and organophosphates), natural plant resistance and biological control. The fumigants (eg methyl bromide) are being phased out because they damage the ozone layer, most of the non-fumigants are being banned because of environmental damage and persistence in groundwater, and biological control has had limited success. These problems are addressed in this project with development of synthetic plant resistance to nematodes, which will benefit horticultural and broadacre farming by reducing pathogen losses and improving quality.Read moreRead less

The aim of this proposal is to establish a high quality, controlled-environment growth facility for plant research in Perth, jointly managed by Murdoch University and the University of Western Australia. This facility is needed urgently to support current research and new initiatives in plant molecular biology and biotechnology. It will focus on the molecular bases of plant growth and defence against pathogens. Outcomes include enhancement of WA plant research and its application to improved agricultural production that will benefit rural industries and promote exports. It will also facilitate postgraduate training in plant biotechnology and enhance career prospects of graduates.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 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

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.
