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
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
Peptidic spider toxins: a novel paradigm for control of insect pests. Many insects are serious pests of Australian crops, livestock, and pets. Australian farmers spend about $300 million per annum on insecticides and acaricides, while Australian consumers spend more than $100 million annually on insecticides for use around the home and garden, and on pets. Viruses disseminated by insects are also responsible for diseases such as dengue, Japanese encephalitis, and Ross River fever. Unfortunately, ....Peptidic spider toxins: a novel paradigm for control of insect pests. Many insects are serious pests of Australian crops, livestock, and pets. Australian farmers spend about $300 million per annum on insecticides and acaricides, while Australian consumers spend more than $100 million annually on insecticides for use around the home and garden, and on pets. Viruses disseminated by insects are also responsible for diseases such as dengue, Japanese encephalitis, and Ross River fever. Unfortunately, many of these insect pests have developed resistance to chemical insecticides. The aim of this research program is to develop a new generation of environmentally-friendly natural products and insect-resistant crops that can be used to control insect pests on farms and around the home and garden.Read moreRead less
Orally active spider toxins: a novel paradigm for control of insect pests. Many insects and other arthropods are serious pests of Australian crops, livestock, and pets.

Safeguarding Australia against invasive arthropod pests. An increasingly serious public health issue for Australia is the emergence of infectious diseases disseminated by arthropods such as ticks and mosquitoes. Arthropod-borne viruses are already the major human pathogens in Australia, and they disproportionately affect Aboriginal communities. The aim of this research is to develop environmentally-sustainable methods for controlling arthropods that destroy crops or disseminate human and animal ....Safeguarding Australia against invasive arthropod pests. An increasingly serious public health issue for Australia is the emergence of infectious diseases disseminated by arthropods such as ticks and mosquitoes. Arthropod-borne viruses are already the major human pathogens in Australia, and they disproportionately affect Aboriginal communities. The aim of this research is to develop environmentally-sustainable methods for controlling arthropods that destroy crops or disseminate human and animal disease. These insecticides will not only provide benefits within Australian territories, but will be useful to our defence forces when operating in overseas locations where arthropod pests are a problem (e.g., malarial regions of Iraq).Read moreRead less
Benign strategies to engineer nematode resistance in plant crops. Applications to other plant pests. Control of plant pests relies on the heavy use of chemical insecticides that cause an extraordinary impact on the environment. Some insect pests have been controlled by the production of toxins (like BT) by the plant. We will combine newly discovered RNA interference and genomics methods to develop innovative solutions to nematode resistance and insect control. Our methods can be tailored to any ....Benign strategies to engineer nematode resistance in plant crops. Applications to other plant pests. Control of plant pests relies on the heavy use of chemical insecticides that cause an extraordinary impact on the environment. Some insect pests have been controlled by the production of toxins (like BT) by the plant. We will combine newly discovered RNA interference and genomics methods to develop innovative solutions to nematode resistance and insect control. Our methods can be tailored to any pest with wide or narrow spectrum of action and does not require the production of toxins by the plant. The novelty of our approach will generate a large amount of intellectual property.Read moreRead less

Generating broad and stable resistance to gemini- and nanoviruses. The ssDNA geminiviruses and nanoviruses are considered a major threat to crop production in the tropics and subtropics. There are currently no effective control strategies for these viruses. We have been developing a novel transgenic strategy for generating resistance to ssDNA viruses based on the activation of a suicide gene in the presence of the viral Rep protein. Importantly, we have demonstrated proof-of-principle using Toba ....Generating broad and stable resistance to gemini- and nanoviruses. The ssDNA geminiviruses and nanoviruses are considered a major threat to crop production in the tropics and subtropics. There are currently no effective control strategies for these viruses. We have been developing a novel transgenic strategy for generating resistance to ssDNA viruses based on the activation of a suicide gene in the presence of the viral Rep protein. Importantly, we have demonstrated proof-of-principle using Tobacco yellow dwarf mastrevirus. In this project, we aim to further develop this strategy into a broad and stable mechanism for generating resistance to all known geminiviruses and nanoviruses.Read moreRead less
Systemic control of nodule proliferation. We aim to clone and characterize the functions of the supernodulation (NTS-1) locus of soybean using positional cloning and functional genomics approaches. Supernodulation fascinatingly results from a mutant Nts-1 gene functioning in the shoot, although the phenotype is expressed as excessive nodule proliferation in the root. The cloned gene will be used to monitor expression changes after inoculation with Bradyrhizobium, treatment with nitrate, nod-fac ....Systemic control of nodule proliferation. We aim to clone and characterize the functions of the supernodulation (NTS-1) locus of soybean using positional cloning and functional genomics approaches. Supernodulation fascinatingly results from a mutant Nts-1 gene functioning in the shoot, although the phenotype is expressed as excessive nodule proliferation in the root. The cloned gene will be used to monitor expression changes after inoculation with Bradyrhizobium, treatment with nitrate, nod-factor, xylem exudates and phytohormones. We will use RT-PCR, in situ hybridisation and reporter gene expression in transgenic plants. Microarray analysis of soybean ESTs (4200 arrayed) will analyse concurrent gene expression changes in both root and shoot.Read moreRead less
To move or not to move: are insect movement strategies driven by plant-induced defences? Plants change chemically when damaged by insects. By showing how movement and feeding is related to these induced defences we can manipulate plant defences to resist insect attack in a more focused way. Our target insects are major pests against which we use large amounts of insecticide. Our research will decrease insect damage to crops using existing genetic machinery of plants as opposed to inserting 'nove ....To move or not to move: are insect movement strategies driven by plant-induced defences? Plants change chemically when damaged by insects. By showing how movement and feeding is related to these induced defences we can manipulate plant defences to resist insect attack in a more focused way. Our target insects are major pests against which we use large amounts of insecticide. Our research will decrease insect damage to crops using existing genetic machinery of plants as opposed to inserting 'novel' toxin-expressing genes. This project builds on Australia's strong record of achievement in agricultural and natural resource research by increasing understanding of the interplay between plant traits and insects. We will build cross-disciplinary research capacity training a new generation of biologists in an exciting area of science.Read moreRead less
