Biochemical, Genomic and Phenomic Analysis of Gastric Parietal Cells from Wildtype and Mutant Mice. The interface between the cell and its environment is the cell membrane. Signals, nutrients, and ions all have to cross this barrier. In addition, the cells contain many specialized intracellular membranous compartments. We know little about the signals that direct the synthesis of these structures and determine their final composition and shape. This grant will utilize acid secretory cells in the ....Biochemical, Genomic and Phenomic Analysis of Gastric Parietal Cells from Wildtype and Mutant Mice. The interface between the cell and its environment is the cell membrane. Signals, nutrients, and ions all have to cross this barrier. In addition, the cells contain many specialized intracellular membranous compartments. We know little about the signals that direct the synthesis of these structures and determine their final composition and shape. This grant will utilize acid secretory cells in the stomach to examine these questions because they contain a very extensive membrane system. We will use a state-of-the-art genetic and cell biological technologies to manipulate and analyse these cells in a whole animal setting.Read moreRead less
Novel mechanisms of bacterial arsenic metabolism - arsenate reduction and arsenite oxidation. Novel arsenic metabolising bacteria (i.e., arsenate respiring and arsenite oxidising), which are both phylogenetically and physiologically unique, have been isolated from arsenic-contaminated areas in Australia. The arsenate respiring bacterium, Chrysiogenes arsenatis, is of particular interest as it is the only organism reported able to respire with arsenate using the respiratory substrate acetate as t ....Novel mechanisms of bacterial arsenic metabolism - arsenate reduction and arsenite oxidation. Novel arsenic metabolising bacteria (i.e., arsenate respiring and arsenite oxidising), which are both phylogenetically and physiologically unique, have been isolated from arsenic-contaminated areas in Australia. The arsenate respiring bacterium, Chrysiogenes arsenatis, is of particular interest as it is the only organism reported able to respire with arsenate using the respiratory substrate acetate as the electron donor. It is proposed that physiological, biochemical and molecular biological studies be carried out to better understand the mechanisms by which these organisms metabolise arsenic. The knowledge gained from these studies will have worldwide application in the development of an arsenic bioremediation system.Read moreRead less

Plants have considerable potential for the bioremediation ("phytoremediation") of contaminated soils, including soils polluted with heavy metals. Progress has been made in understanding the physiological and biochemical mechanisms by which plants accumulate and detoxify heavy metals. One important aspect of metal detoxification is the transport of metals across cell membranes. The recently completed genome project for the model plant Arabidopsis has identified a family of genes encoding heavy metal transport proteins. This project aims to investigate the roles of these genes in metal detoxification. In the longer term this knowledge can be applied to the improvement of phytoremediation processes.Read moreRead less
Mechanisms of zinc transport and homeostasis in the plant, Arabidopsis. Zinc-deficiency is one of the most widespread factors limiting crop production and affects many soils of south-east and south-west Australia. Certain zinc-efficient (ZE) crop cultivars are able to grow well under zinc deficient conditions but the genetic basis for ZE is not well understood. Using a model organism such as Arabidopsis to identify genes in plants that are important in zinc transport and homeostasis will ultimat ....Mechanisms of zinc transport and homeostasis in the plant, Arabidopsis. Zinc-deficiency is one of the most widespread factors limiting crop production and affects many soils of south-east and south-west Australia. Certain zinc-efficient (ZE) crop cultivars are able to grow well under zinc deficient conditions but the genetic basis for ZE is not well understood. Using a model organism such as Arabidopsis to identify genes in plants that are important in zinc transport and homeostasis will ultimately allow us to assess whether the homologous genes in crop species are responsible for ZE. This may contribute to more rapid and directed strategies in breeding ZE crop cultivars.Read moreRead less

Plants and plant-based industries are essential for the provision of food, clothing and building materials and underpin the economies of rural communities. Plant yield and quality and the biodiversity of natural systems are dramatically reduced by disease. The fundamental knowledge gained from our research will enable manipulation of the factors that enhance disease resistance resulting in a significant benefit to Australian agriculture and protection of our natural resources. The current reliance for disease control on chemicals that damage the environment will be reduced and our research will contribute directly to the provision of cheaper, simpler and more effective methods of control.
