Membrane transporters mediating 2,4-D resistance in wild radish. This project aims to identify the membrane transporter protein(s) that endows resistance to the herbicide 2,4-D in wild radish (Raphanus raphanistrum). Wild radish is a particular problem in Australia due to its high competitiveness with crops and widespread resistance to other herbicides. 2,4-D resistance is rapidly increasing and threatening crop production in Australia and the United States. The anticipated outcome of the projec ....Membrane transporters mediating 2,4-D resistance in wild radish. This project aims to identify the membrane transporter protein(s) that endows resistance to the herbicide 2,4-D in wild radish (Raphanus raphanistrum). Wild radish is a particular problem in Australia due to its high competitiveness with crops and widespread resistance to other herbicides. 2,4-D resistance is rapidly increasing and threatening crop production in Australia and the United States. The anticipated outcome of the project is to identify strategies to minimise 2,4-D resistance in wild radish by interfering with the specific transporters that confer resistance and by taking advantage of the fitness cost associated with resistance in some populations. It is expected that this will help to improve crop yields and preserve 2,4-D as an effective herbicide.Read moreRead less
In touch with the environment: dissecting early tactile responses in plants. This project aims to identify the regulatory mechanisms that control touch-responses in plants. Although plants cannot relocate in the face of danger, they are able to sense mechanical manipulations from the environment. These could be caused by pathogens, herbivores, rain or even wind. This touch-responsiveness of plants is essential for pathogen resistance and for triggering architectural changes to overcome obstacles ....In touch with the environment: dissecting early tactile responses in plants. This project aims to identify the regulatory mechanisms that control touch-responses in plants. Although plants cannot relocate in the face of danger, they are able to sense mechanical manipulations from the environment. These could be caused by pathogens, herbivores, rain or even wind. This touch-responsiveness of plants is essential for pathogen resistance and for triggering architectural changes to overcome obstacles and prevent mechanical damage. Using a comprehensive tool set of genetics, genomics and proteomics, this project aims to identify the upstream regulators that control touch responses. Furthermore, it is expected to expand our understanding of the physiological impacts of touch-responses on growth and stress tolerance.Read moreRead less
Identifying the biochemical and molecular bases of 2,4-D herbicide resistance in the economically important weed Raphanus raphanistrum (wild radish). An alarming increase in the incidence of field-evolved resistance to 2,4-D in Australian wild radish has recently been observed. The project aims to characterise the molecular and biochemical mechanism(s) of resistance to help minimise its impact on Australian cropping.
Putting new herbicide targets on the table. This project aims to discover plant processes and plant proteins that can be the target for new herbicides. Australia's food security is being threatened by a rise in resistance to herbicides, the chemicals relied on to control weeds. In over 20 years a truly new herbicide has not appeared. This project aims to provide validated new targets to engage agrochemical industry and accelerate the rate farmers get tools to manage problematic weeds, the major ....Putting new herbicide targets on the table. This project aims to discover plant processes and plant proteins that can be the target for new herbicides. Australia's food security is being threatened by a rise in resistance to herbicides, the chemicals relied on to control weeds. In over 20 years a truly new herbicide has not appeared. This project aims to provide validated new targets to engage agrochemical industry and accelerate the rate farmers get tools to manage problematic weeds, the major yield penalty for both developed and developing world agriculture. The project expects enable effective collaboration with industry to develop new herbicides.Read moreRead less
Understanding trifluralin resistance in annual ryegrass, a major Australian agricultural weed. This project aims to better understand the biochemical and molecular basis of trifluralin resistance in annual ryegrass. The herbicide trifluralin is an alternative to soil cultivation in controlling crop-infesting weeds such as annual ryegrass. However, resistance to trifluralin in annual ryegrass now looms. A fundamental understanding and insight into trifluralin resistance will assist resistance man ....Understanding trifluralin resistance in annual ryegrass, a major Australian agricultural weed. This project aims to better understand the biochemical and molecular basis of trifluralin resistance in annual ryegrass. The herbicide trifluralin is an alternative to soil cultivation in controlling crop-infesting weeds such as annual ryegrass. However, resistance to trifluralin in annual ryegrass now looms. A fundamental understanding and insight into trifluralin resistance will assist resistance management, trifluralin sustainability and soil conservation. This will provide significant benefits for Australian grain production and soil conservation.Read moreRead less

Summary
Structure-based investigations into new modes of action for herbicides. This project aims to focus on identifying and providing protein structure information for new protein targets against which herbicides can be developed. Food security for a growing population relies on agriculture, which in turn relies on herbicides. Presently, herbicide efficacy is under serious threat from resistant weeds.

This project aims to focus on identifying and providing protein structure information for new protein targets against which herbicides can be developed. Food security for a growing population relies on agriculture, which in turn relies on herbicides. Presently, herbicide efficacy is under serious threat from resistant weeds. In this project, innovative applications of chemical libraries and exploiting a little-known connection between plants and human parasites will help to resolve the structure of herbicide targets for the development of new herbicides to ensure future food security.Read moreRead less
