Signal transduction and the control of bacterial respiration by the NtrYX two component regulatory system. This proposal will define the structural and functional properties of the NtrYX two component signal transduction and define its role in the regulation of respiratory gene expression. The human pathogen Neisseria gonorrhoeae will be used as a model organism for a diverse range of 'oxidase positive' bacteria that possess NtrYX. The outcome will be a major contribution to the understanding of ....Signal transduction and the control of bacterial respiration by the NtrYX two component regulatory system. This proposal will define the structural and functional properties of the NtrYX two component signal transduction and define its role in the regulation of respiratory gene expression. The human pathogen Neisseria gonorrhoeae will be used as a model organism for a diverse range of 'oxidase positive' bacteria that possess NtrYX. The outcome will be a major contribution to the understanding of way in which respiratory gene expression is controlled in bacterial species for which Escherichia coli is not a suitable model.

Redirecting Carbon Flow through Mesophyll and Bundle Sheath Cells of Sugarcane to Produce Poly-3-Hydroxybutyrate. This project is part of the National Priorities "Frontier Technologies for Building and Transforming Australian Industries." Using innovative plant metabolic engineering technologies combined with sophisticated computer modeling we are generating green plants that produce renewable, biodegradable, bioplastics possessing properties such that they are suitable replacements for petrol ....Redirecting Carbon Flow through Mesophyll and Bundle Sheath Cells of Sugarcane to Produce Poly-3-Hydroxybutyrate. This project is part of the National Priorities "Frontier Technologies for Building and Transforming Australian Industries." Using innovative plant metabolic engineering technologies combined with sophisticated computer modeling we are generating green plants that produce renewable, biodegradable, bioplastics possessing properties such that they are suitable replacements for petroleum-derived products in many applications. During the course of these studies, we are increasing our basic level of understanding of plant metabolism of important bioenergy crops. The production of renewable, bioplastics in sugarcane will help to diversify the Australian sugarcane industry by providing a value-added product with significant world-wide markets.Read moreRead less
Sleeping snails: investigating hypometabolism to reveal critical factors that aid life extension. The apparent state of eternal dormancy has fascinated people for hundreds of years. This project will explore new frontiers in life extension and snail control by defining those genes and peptides involved in snail hypometabolism. To achieve this, the project will interrogate the snails' natural state of hypometabolism called estivation.
