Development of Novel Pesticidal Agents. We have discovered a family of naturally occurring plant proteins called the cyclotides that have potent insecticidal activity against Helicoverpa species, one of the major pests on cotton and corn in Australia and world wide. Preliminary evidence has shown that they also have activity against major pests to livestock in Australia, including sheep blowflies. To develop these proteins as potential pesticidal agents it is necessary to understand the struct ....Development of Novel Pesticidal Agents. We have discovered a family of naturally occurring plant proteins called the cyclotides that have potent insecticidal activity against Helicoverpa species, one of the major pests on cotton and corn in Australia and world wide. Preliminary evidence has shown that they also have activity against major pests to livestock in Australia, including sheep blowflies. To develop these proteins as potential pesticidal agents it is necessary to understand the structural basis for their activity. We will do this by chemically synthesising peptides with selected residues mutated to determine their effects on activity.Read moreRead less
Influence of high temperature on phenology, metabolism and the fate of axillary buds and inflorescences in grapevine. Subtropical regions in Australia, due to a warm climate, land and water availability, have the potential to produce a variety of agricultural produce, particularly fruit, to meet market demand. However adoption of fruit crops, many of which, including table grape, have temperate origins, requires intensive management. Despite years of agronomic R&D, production remains variable du ....Influence of high temperature on phenology, metabolism and the fate of axillary buds and inflorescences in grapevine. Subtropical regions in Australia, due to a warm climate, land and water availability, have the potential to produce a variety of agricultural produce, particularly fruit, to meet market demand. However adoption of fruit crops, many of which, including table grape, have temperate origins, requires intensive management. Despite years of agronomic R&D, production remains variable due to a lack of fundamental knowledge on how climate impacts on the development cycle, particularly flowering, required to produce fruit. This proposal will carry out basic research to provide knowledge that will enable consistent production and expansion of table grape and other temperate crop industries.Read moreRead less
The future of fruit fly control: making the Sterile Insect Technique work for Queensland fruit fly. The future of fruit fly control in Australia lies in the Sterile Insect Technique (SIT): it is the only non-pesticide option that can totally eliminate pest populations. Millions of dollars have already been invested to establish an SIT program against Queensland fruit fly (Q-fly) in southern and eastern Australia, but this program is currently largely ineffective due to the poor performance of t ....The future of fruit fly control: making the Sterile Insect Technique work for Queensland fruit fly. The future of fruit fly control in Australia lies in the Sterile Insect Technique (SIT): it is the only non-pesticide option that can totally eliminate pest populations. Millions of dollars have already been invested to establish an SIT program against Queensland fruit fly (Q-fly) in southern and eastern Australia, but this program is currently largely ineffective due to the poor performance of the mass-reared sterile flies. This project will apply genetic, ecological and technical solutions to the problems facing the current Q-fly control program. Effective control of Q-fly will enhance the international competitiveness of Australia's horticultural industries.Read moreRead less
Protection of Botanical Innovation: A legal analysis of the scope and operation of national and international plant breeder's rights. Plants play a crucial role in Australian society: they are a major source of nutrition, shelter, clothing, fuel, medicines and aesthetic pleasure. They also make an important contribution to the Australian economy.

Plants play a crucial role in Australian society: they are a major source of nutrition, shelter, clothing, fuel, medicines and aesthetic pleasure. They also make an important contribution to the Australian economy. The legislative regime established under the 1994 Plant Breeder's Rights Act was designed to promote research, investment and innovation in Australian plant breeding. A lack of familiarity and widespread misunderstanding mean that the system is under-utilised with adverse consequences for plant innovation and Australia's economy. This groundbreaking research will provide a comprehensive analysis of plant breeder's rights in Australia to maximise understanding and awareness amongst key stakeholders.Read moreRead less
Regulation of Plant Development by Small RNAs. Understanding the roles of small RNAs and their pathways is a new field of research that is giving, and will continue to give profound insights into how multicellular organisms regulate gene expression at a genomic level. Research in this area has already led to RNA interference technology, by which almost any gene can be switched off, and there is considerable potential for other gene silencing and trait modification technologies to emerge. The pro ....Regulation of Plant Development by Small RNAs. Understanding the roles of small RNAs and their pathways is a new field of research that is giving, and will continue to give profound insights into how multicellular organisms regulate gene expression at a genomic level. Research in this area has already led to RNA interference technology, by which almost any gene can be switched off, and there is considerable potential for other gene silencing and trait modification technologies to emerge. The project will yield insights into fundamental biological processes which are expected to engender applications in agriculture and biotechnology. It will maintain and enhance Australia's position in this area.Read moreRead less

Better guidance on alternative land cropping systems that can be grown to optimise farm productivity is needed. Micro-level land classes maps have been identified hby AgWA, farmers and regional development and community groups as an urgent need to enable them to design resilient and diversified farming systems. To this end, we propose integrating high resolution digital multispectral images, GIS and multi-criteria decision analysis techniques to help farmers use input appropriate to the productive capacity of their paddocks and to elaborate sound farm planning based on the potential of the land for specific land uses.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.

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
Manipulation of apoptosis-related genes to generate novel disease resistances in banana. Bananas are one of Australia's most important fruit crops. However, the industry is continually threatened by numerous diseases including yellow and black Sigatoka, Fusarium wilt and bunchy top. Control of these diseases currently requires either extensive pesticide treatments or complex agronomic procedures, of which most are ineffective, expensive or environmentally damaging.

However, the industry is continually threatened by numerous diseases including yellow and black Sigatoka, Fusarium wilt and bunchy top. Control of these diseases currently requires either extensive pesticide treatments or complex agronomic procedures, of which most are ineffective, expensive or environmentally damaging. The aim of this project is to utilise a novel strategy to generate transgenic bananas with resistance to these diseases. The benefit will be both economic and environmental as implementation should significantly reduce or eliminate pesticide use. Importantly, this strategy can potentially be extrapolated to many other crops.Read moreRead less
