Preparation of Photo-Affinity Molecular Probes for the Identification of Gibberellin Receptors. Bioactive gibberellins affect numerous processes during plant growth and development, including seed germination, leaf expansion, stem elongation, flowering and fruit development. However, only very limited information is available regarding their mode of action at the molecular level. The central aim of the project is to prepare a family of photo-affinity molecular probes based on the gibberellin m ....Preparation of Photo-Affinity Molecular Probes for the Identification of Gibberellin Receptors. Bioactive gibberellins affect numerous processes during plant growth and development, including seed germination, leaf expansion, stem elongation, flowering and fruit development. However, only very limited information is available regarding their mode of action at the molecular level. The central aim of the project is to prepare a family of photo-affinity molecular probes based on the gibberellin molecule that will be designed to provide critical information on the location and structure of gibberellin receptors. Screening of the probes for potential effectiveness will be determined initially by the measurement of alpha-amylase produced in a standard barley aleurone assay.Read moreRead less

Disruption of Sex Pheromone Biosynthesis: A Novel Control Method for Pestiferous Fruit Flies by. Fruit flies from the genus Bactrocera are economically important worldwide. B. tryoni, (Queensland fruit fly) is the most damaging horticultural pest in Australia and B. oleae (olive fly) is a major European pest. These flies use chemicals of similar but distinct structure for communication and particularly for finding mates. This research will examine the pathways and enzymes these flies use to sy ....Disruption of Sex Pheromone Biosynthesis: A Novel Control Method for Pestiferous Fruit Flies by. Fruit flies from the genus Bactrocera are economically important worldwide. B. tryoni, (Queensland fruit fly) is the most damaging horticultural pest in Australia and B. oleae (olive fly) is a major European pest. These flies use chemicals of similar but distinct structure for communication and particularly for finding mates. This research will examine the pathways and enzymes these flies use to synthesise sex pheromones. We propose that understanding the chemical and biochemical steps employed by the flies will allow us to design inhibitors to prevent pheromone production and thus provide a novel, species specific method for controlling fruit flies.Read moreRead less

Design and evaluation of new environmentally-benign herbicides that inhibit branched-chain amino acid biosynthesis. Herbicides interfere with processes that occur in plants, such as photosynthesis or the biosynthesis of certain amino acids. In this project we will focus on branched-chain amino acid biosynthesis, designing and evaluating inhibitors of the first two enzymes in this process. Based on their three dimensional structures we will develop an understanding of the molecular features that ....Design and evaluation of new environmentally-benign herbicides that inhibit branched-chain amino acid biosynthesis. Herbicides interfere with processes that occur in plants, such as photosynthesis or the biosynthesis of certain amino acids. In this project we will focus on branched-chain amino acid biosynthesis, designing and evaluating inhibitors of the first two enzymes in this process. Based on their three dimensional structures we will develop an understanding of the molecular features that contribute to a potent inhibitor and those that are required for it to be effective upon plants. Using this information we will design and synthesis new compounds as potential environmentally-benign herbicides.Read moreRead less
