This research will significantly advance our understanding of the basic biological processes that underpin the fertility rate of all mammals and are key to the immediate and future health and well-being of Australian landscape and society. Understanding the processes that maintain healthy quiescent oocytes over many years before activation and subsequent growth will enable development of methods of increasing productivity in domestic animals and enhancing fertility in endangered species. Knowledge of these cellular mechanisms will underpin biotechnology platforms necessary for novel methods of feral animal population control thus contributing at multiple levels to an economically sustainable Australia.Read moreRead less
The role of the Ttyh1 protein in cell activation. We have cloned TTYH1, a human homologue of the Drosophila melanogaster tweety gene. The mouse gene has also been identified. The predicted structure of the protein is a membrane protein with 5 transmembrane domains. We have also expressed a GFP-tagged fusion protein in mouse fibroblasts. Confocal microscopy indicates that this protein is likely to be a novel adhesion molecule, with a cellular distribution characteristic of molecules such as integ ....The role of the Ttyh1 protein in cell activation. We have cloned TTYH1, a human homologue of the Drosophila melanogaster tweety gene. The mouse gene has also been identified. The predicted structure of the protein is a membrane protein with 5 transmembrane domains. We have also expressed a GFP-tagged fusion protein in mouse fibroblasts. Confocal microscopy indicates that this protein is likely to be a novel adhesion molecule, with a cellular distribution characteristic of molecules such as integrins. We aim to determine the function of Ttyh1, its interacting intra- and extra-cellular proteins and to assess its candidature as a molecule of importance in cell migration and adhesion.Read moreRead less
Examination of the Calcium Signalling Dynamics Linked to Integrin Adhesion Utilising a Novel Micro-imaging System. This study aims at increasing our understanding of the fundamental cell processes that allow cells to adhere to surfaces. The proposed study will lead to a greater understanding of the calcium signalling mechanisms that are fundamental to diverse biological phenomena such as, tissue regeneration and repair, blood clotting, cancer metastasis, and neuronal cell function.

Hierarchical modeling of protein interactions. Protein interactions play a central role in function and structural organization of cells. Their elucidation is essential for a better understanding of many cellular processes from signal transduction to enzyme inhibition. The aim of this project is to utilize the unprecedented powers of current supercomputers in developing a hierarchical model of protein interactions. The method combines Brownian dynamics at large distances and long time scales ....Hierarchical modeling of protein interactions. Protein interactions play a central role in function and structural organization of cells. Their elucidation is essential for a better understanding of many cellular processes from signal transduction to enzyme inhibition. The aim of this project is to utilize the unprecedented powers of current supercomputers in developing a hierarchical model of protein interactions. The method combines Brownian dynamics at large distances and long time scales with molecular dynamics at small distances and shorter times. Applications to both membrane proteins (blocking of ion channels by toxins and drugs) and globular proteins (ligand binding to receptors and protein association) will be considered.Read moreRead less
Selective secretion: a novel mechanism of protein trafficking and its role in Phytophthora pathogenicity. Agriculturally important crops and over 3,000 Australian native plants are susceptible to diseases caused by Phytophthora, fungus-like pathogens that live in the soil. Economic losses exceed $200m pa and natural ecosystems are being destroyed on a vast scale. Phytophthora control depends upon a limited number of chemical inhibitors to which resistance has already emerged. New control stra ....Selective secretion: a novel mechanism of protein trafficking and its role in Phytophthora pathogenicity. Agriculturally important crops and over 3,000 Australian native plants are susceptible to diseases caused by Phytophthora, fungus-like pathogens that live in the soil. Economic losses exceed $200m pa and natural ecosystems are being destroyed on a vast scale. Phytophthora control depends upon a limited number of chemical inhibitors to which resistance has already emerged. New control strategies are urgently needed. This research will investigate a novel mechanism for release of infection material recently discovered in Phytophthora cells, and will increase our understanding of how Phytophthora infects host plants, providing vital information required for the development of new, environmentally-safe inhibitors.

Elucidating the interactions between drought tolerance and photoprotection in plants. The 2002-03 drought cost Australia in the order of $10Billion and 70,000 jobs. Associated with reduced rainfall is increased sunlight irradiance, which exacerbates the reduction in crop yield due to the combined damage of a water deficit and oxidative damage caused by the excess light. Plants have networks of responses to minimise damage due to drought and excess light. We have identified a novel class of genes ....Elucidating the interactions between drought tolerance and photoprotection in plants.

Associated with reduced rainfall is increased sunlight irradiance, which exacerbates the reduction in crop yield due to the combined damage of a water deficit and oxidative damage caused by the excess light. Plants have networks of responses to minimise damage due to drought and excess light. We have identified a novel class of genes that optimise or alter different aspects of these networks and we wish to define the nature of that optimisation to determine how it could be transfered to crop plants.Read moreRead less
Chloroplast pigments as developmental signals. This project will define roles of chloroplast pigments in cellular signaling, plant growth and development. Effective communication between the chloroplast and the nucleus is essential for maintaining viability and productivity of the cell. Similarly, long-distance signaling is required for coordinated growth and development and we hypothesise that pigments also have importance in this role. Our proposal brings together the multidisciplinary skills ....Chloroplast pigments as developmental signals. This project will define roles of chloroplast pigments in cellular signaling, plant growth and development. Effective communication between the chloroplast and the nucleus is essential for maintaining viability and productivity of the cell. Similarly, long-distance signaling is required for coordinated growth and development and we hypothesise that pigments also have importance in this role. Our proposal brings together the multidisciplinary skills and resources of six investigators to define how certain carotenoids and chlorophyll precursors regulate gene expression and to determine the identity of what is most likely a carotenoid derivative with hormonal properties that controls lateral branch growth.Read moreRead less
