Genetic control of plant organ growth. Plants organs, such as leaves and petals, have a distinct size and shape reflecting differences in growth. Despite its importance, very little is known about the mechanisms that regulate growth. The objectives of this proposal are a) to test whether organ growth depends on cell-cell signalling and b) to identifying genes that regulate growth, and to characterize their molecular function.
Does a novel class of small RNA molecules control self-incompatibility in solanaceous plants? Self-incompatibility is a simple and genetically defined cell recognition system that prevents inbreeding in many plant species. Flowers of self-incompatible plants can distinguish self pollen from foreign pollen, and allow only foreign pollen to fertilise their egg cells. This proposal will investigate the possibility that the part of the genetic self-incompatibility locus controlling recognition of ....Does a novel class of small RNA molecules control self-incompatibility in solanaceous plants? Self-incompatibility is a simple and genetically defined cell recognition system that prevents inbreeding in many plant species. Flowers of self-incompatible plants can distinguish self pollen from foreign pollen, and allow only foreign pollen to fertilise their egg cells. This proposal will investigate the possibility that the part of the genetic self-incompatibility locus controlling recognition of pollen is a novel type of gene that encodes a small RNA molecule but no protein. Knowledge gained by studying the self-incompatibility genes will help us to understand how plant cells recognise each other, and may allow us to manipulate seed (and hence crop) production.Read moreRead less

Summary
A liquid chromatograph-mass spectrometer for plant metabolomics. The Australian Agrifood sector will benefit significantly from the establishment of functional genomics platform technologies, such as metabolomics, that underpin 'Systems Biology'; a new branch of biology that attempts to discover and understand biological properties that emerge from the interactions of many system elements.

The Australian Agrifood sector will benefit significantly from the establishment of functional genomics platform technologies, such as metabolomics, that underpin 'Systems Biology'; a new branch of biology that attempts to discover and understand biological properties that emerge from the interactions of many system elements. Australian agriculture will benefit through the development of techniques to improve both yield and quality through minimising the effects of abiotic and biotic stresses, and a reduced dependence on inputs (eg fertilisers) leading to environmentally sustainable production systems. Ultimately this will result in enhanced food quality and analytical methods to monitor quality and safety characteristics of food.Read moreRead less
Pheromone evolution and ecology in insects on intra- and inter-specific scales. The study of pheromones is important because so many insect pests use them as part of their reproductive life cycle, increasing their potential to cause damage to crops and other natural products. My research will improve our understanding of the evolution of pheromones and communication by smell, a subject that has been largely neglected by evolutionary biologists. More specifically, by identifying the ecological fa ....Pheromone evolution and ecology in insects on intra- and inter-specific scales. The study of pheromones is important because so many insect pests use them as part of their reproductive life cycle, increasing their potential to cause damage to crops and other natural products. My research will improve our understanding of the evolution of pheromones and communication by smell, a subject that has been largely neglected by evolutionary biologists. More specifically, by identifying the ecological factors that influence pheromone evolution, the research will help to assess the long-term consequences of the control measures currently used against such pests and, in particular, will have direct applications to the prevention of damage to Australian pine plantations by the invasive five-spined bark beetle, Ips grandicollis.

Australians are increasingly exposed to insect-transmitted diseases such as dengue fever. Novel biocontrol methods using the bacterium Wolbachia aim to control insect populations to reduce disease transmission. Our research will be the first to investigate genomic variation and the process of adaptation to new insect hosts in Wolbachia. The novel data and understanding of evolutionary processes we generate will be critical for screening bacterial biocontrol candidates and designing biocontrol release strategies. It will also strengthen the position of Australian research as a world-leader in the fusion of post-genomics and applied microbiology. Read moreRead less

This project will address several neglected but fundamental issues in the field of chemical communication and insect diversity. These include the evolutionary importance of receptor structures in a communication system, and the basis of diversity in one of the most defining characteristics of insects: antennae. The moth species in the proposed experiments are commercial pests of crops and therefore understanding of the evolutionary processes shaping their communication systems and mating behaviour will contribute to better predictive knowledge of the effects of control measures used against them. The project will also involve international collaboration to learn and develop new a technique in the analysis of pheromone communication. Read moreRead less
Olfactory signal transduction in Drosophila melanogaster. This project will strengthen Australia's research capabilities in the areas of molecular neurobiology and neurogenetics. The project will equip students with the intellectual and technical skills needed to work in priority areas such as genomics and biotechnology, as well as in medical and agricultural research, and education.

This project will strengthen Australia's research capabilities in the areas of molecular neurobiology and neurogenetics. The project will equip students with the intellectual and technical skills needed to work in priority areas such as genomics and biotechnology, as well as in medical and agricultural research, and education. The research has possible long term applications in modifying the behaviour of insects of agricultural or medical importance. For example, by inhibiting the ability of insects to perceive specific odours it may ultimately be possible to prevent insects that carry disease from identifying target animals, or plant pests from locating their host plants.Read moreRead less
Olfactory signalling and coding in Drosophila and other insects. Animals rely on olfactory cues to detect food, danger, and others of the same species. The olfactory systems of Drosophila and other insects are simpler than those of mammals, yet complex enough to offer fascinating systems for studying neural information processing.

The olfactory systems of Drosophila and other insects are simpler than those of mammals, yet complex enough to offer fascinating systems for studying neural information processing. This project aims to investigate the role of the Drosophila odorant receptors in olfactory coding, and to use multiple approaches to isolate components of the poorly understood insect olfactory signal transduction pathway. In addition, the role of the NO/cGMP pathway in olfactory signalling will be studied using an olfactory mutant that has nitric oxide synthase defects.Read moreRead less
