Kinetics of phytochemical adsorption and desorption in clay nanoparticles. Biologically active phytochemicals are of increasing importance in many areas of human endeavour. There is a growing interest in the agricultural uses of such compounds. A major limiting factor has been the control of the release rate and the general susceptibility to UV breakdown. This project aims to develop a platform technology for the controlled release and for improved UV protection of these chemicals. Through the s ....Kinetics of phytochemical adsorption and desorption in clay nanoparticles. Biologically active phytochemicals are of increasing importance in many areas of human endeavour. There is a growing interest in the agricultural uses of such compounds. A major limiting factor has been the control of the release rate and the general susceptibility to UV breakdown. This project aims to develop a platform technology for the controlled release and for improved UV protection of these chemicals. Through the studies on the adsorption and desorption kinetics of select phytochemicals, we aim to develop a nanoparticle clay based carrier system and a predictive model for control of the desorption characteristics. Such a platform technology will enable wide range of applications of phytochemical products in pesticides, plant stress alleviating and growth enhancing areas.Read moreRead less
Sterol interference as a new approach to the control of insect pests of crops. This project aims to develop a new approach to control chewing insect pests of crops. This will be achieved by interfering with insect sterol metabolism so that they fail to grow and reproduce normally.
A novel reversible male sterility system for hybrid seed production in canola, cotton and oilseed mustard. Demand for grains, fibre and other agricultural products has recently increased significantly. Hence, the security of food production is emerging as a critical global issue. We have identified a central component (AtMYB103) controlling tapetum and thus pollen development and designed a novel reversible male sterility system using AtMYB103. The efficient hybrid seed production systems develo ....A novel reversible male sterility system for hybrid seed production in canola, cotton and oilseed mustard. Demand for grains, fibre and other agricultural products has recently increased significantly. Hence, the security of food production is emerging as a critical global issue. We have identified a central component (AtMYB103) controlling tapetum and thus pollen development and designed a novel reversible male sterility system using AtMYB103. The efficient hybrid seed production systems developed in this project for canola, cotton and mustard will increase the productivity of the Australian oilseed and fibre industries. AtMYB103 gene is conserved among many crop plants. Hence, the new technologies and knowledge gained will be applicable to a wide range of crop plants and have important implications for the agricultural and food industries.Read moreRead less
Development of eco-friendly alternatives for crop pest management. This project will produce novel insecticides to protect cotton and other crops from a range of economically damaging pests. It will lead to a more sustainable and eco-friendly cotton industry by reducing the dependence on chemical insecticides and genetically modified cotton plants.
Enhancement of plant proteinase inhibitors for the protection of crop plants against insect attack. The aim of this project is to characterise the interactions between various known plant proteinase inhibitors and the major digestive enzymes of insects by structural and dynamic studies and to utilise mutational studies to design new inhibitors that more effectively bind to target proteinases. The outcomes will be the knowledge to design specific inhibitors to give optimal inhibition of specific ....Enhancement of plant proteinase inhibitors for the protection of crop plants against insect attack. The aim of this project is to characterise the interactions between various known plant proteinase inhibitors and the major digestive enzymes of insects by structural and dynamic studies and to utilise mutational studies to design new inhibitors that more effectively bind to target proteinases. The outcomes will be the knowledge to design specific inhibitors to give optimal inhibition of specific insect proteinases. This knowledge will lead to novel approaches to protect economically important crops, such as cotton, from insect pests in Australia - potentially saving tens of millions of dollars per annum in chemical pesticide use and enhancing crop production in Australia and internationally.Read moreRead less
Minimising environmental and public health risk of pesticide application through understanding the droplet-canopy interface. Pesticides are essential tools for agricultural industries in most Australian cropping systems. Accurate placement of pesticide droplets onto plant surfaces is the key step in guaranteeing high quality food production, while loss of droplets to air and soil are inefficiencies leading to environmental and public health risks. Innovations in plant architecture informatics wi ....Minimising environmental and public health risk of pesticide application through understanding the droplet-canopy interface. Pesticides are essential tools for agricultural industries in most Australian cropping systems. Accurate placement of pesticide droplets onto plant surfaces is the key step in guaranteeing high quality food production, while loss of droplets to air and soil are inefficiencies leading to environmental and public health risks. Innovations in plant architecture informatics will be used to develop an improved understanding of droplet/plant canopy interactions that will be validated through wind tunnel experimentation. This research will result in a risk assessment tool that can be applied generally to controlled spray applications of pesticides.Read moreRead less
