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
Evaluating Research Policy in Australian Broadacre Agriculture - Accounting for Interactions between the Beef, Sheep Meat, Wool, and Grains Industries. This project studies the returns from R&D investments in Australia's broadacre agricultural industries and equity in the funding of these investments. The contribution is to explicitly recognise the interaction across cattle, sheep and cropping enterprises, while past analyses have been single industry approach. Econometric models of multi-output ....Evaluating Research Policy in Australian Broadacre Agriculture - Accounting for Interactions between the Beef, Sheep Meat, Wool, and Grains Industries. This project studies the returns from R&D investments in Australia's broadacre agricultural industries and equity in the funding of these investments. The contribution is to explicitly recognise the interaction across cattle, sheep and cropping enterprises, while past analyses have been single industry approach. Econometric models of multi-output profit function for Australian broadacre agriculture and demand systems involving these products are estimated. A multi-industry equilibrium displacement model is developed to simulate the incidence of both costs and returns of agricultural R&D, with cross-industry interaction recognised. The project is likely to contribute to the way agricultural research is administered and funded in Australia.Read moreRead less
