The sponge genome project and the evolution of multicellularity: using comparative genomics and developmental biology to reconstruct the first animals. Recently the entire genome from a living fossil - a sponge from the Great Barrier Reef - was sequenced (jointly supported by the ARC and US Department of Energy). As this genome is assembled and analysed, many of the fundamental biological processes that underlie the construction and evolution of all animals, including humans, will be revealed. ....The sponge genome project and the evolution of multicellularity: using comparative genomics and developmental biology to reconstruct the first animals. Recently the entire genome from a living fossil - a sponge from the Great Barrier Reef - was sequenced (jointly supported by the ARC and US Department of Energy). As this genome is assembled and analysed, many of the fundamental biological processes that underlie the construction and evolution of all animals, including humans, will be revealed. In addition, sponge genomics will fuel innovations in medicine and biotechnology. Specifically, sponges are renowned for their capacity to synthesise bioactive compounds used in drug development, and high-grade silica used for semi-conductor construction. This project will identify the gene networks controlling these biosynthetic processes.Read moreRead less
Variation in larval gene expression in a marine invertebrate: implications for population divergence via differential settlement response. Evolutionary and ecological functional genomics is an emerging field that integrates gene profiling technologies with experimental and field approaches of ecology and evolution. I take this approach to address a key problem in marine invertebrate biology: how do larvae respond to their environment and how does variation in this response influence the distribu ....Variation in larval gene expression in a marine invertebrate: implications for population divergence via differential settlement response. Evolutionary and ecological functional genomics is an emerging field that integrates gene profiling technologies with experimental and field approaches of ecology and evolution. I take this approach to address a key problem in marine invertebrate biology: how do larvae respond to their environment and how does variation in this response influence the distribution and evolution of a species? I will use a marine gastropod (abalone) model, for which there exists substantial development and population genetic data, and established aquaculture methodologies. Outcomes of this study will enhance knowledge of the stock structure of this and other commercial fisheries, as well as aquaculture efficiency.Read moreRead less

The transcriptome, genome and metagenome of Acropora millepora: a model system for studying coral health and disease. Corals have an iconic significance for Australia, which has the best-preserved reef system in the world. The Great Barrier Reef is worth more than $6 billion per year to the Australian economy, and provides employment for 68000 people. The research will provide insights into the molecular bases of stress and disease in corals and the internal mechanisms by which corals attempt to ....The transcriptome, genome and metagenome of Acropora millepora: a model system for studying coral health and disease.

A genetic analysis of the role of an atypical hexokinase in gene regulation. This project addresses a question which is relevant to all living things-how do changes in the environment of a cell bring about a change in gene expression? The aim of this project is to investigate the role of hexokinases in gene regulation by studying the Aspergillus nidulans xprF gene, which encodes an an unusual hexokinase. Hexokinases are thought to be the glucose sensors in plants, animals and fungi, and play a ....A genetic analysis of the role of an atypical hexokinase in gene regulation.

Hexokinases are thought to be the glucose sensors in plants, animals and fungi, and play a role in the development of diabetes in humans. In plants, sugars affect many processes including growth, flowering, photosynthesis, nitrogen metabolism, starch synthesis, pigmentation and response to pathogens.Read moreRead less

Summary
Sickle cell anemia and thalassemia are the commonest genetic disorders worldwide. Those affected suffer devastating clinical sequelae and mortality in the first twenty years of life remains high. A cure for these diseases is dependent on the replacement of the affected or absent hemoglobin protein chains with normally functioning hemoglobins. This is evident in rare patients who co-inherit a natural mutation which elevates fetal hemoglobin (HbF), as these patients have a dramatically ameliorated ....Sickle cell anemia and thalassemia are the commonest genetic disorders worldwide. Those affected suffer devastating clinical sequelae and mortality in the first twenty years of life remains high. A cure for these diseases is dependent on the replacement of the affected or absent hemoglobin protein chains with normally functioning hemoglobins. This is evident in rare patients who co-inherit a natural mutation which elevates fetal hemoglobin (HbF), as these patients have a dramatically ameliorated clinical course. Therefore, treatment strategies which could reactivate fetal globin gene expression after birth should be explored for these diseases. To achieve this goal we must further our understanding of the normal mechanisms of developmental regulation of globin gene expression. To this end we have recently identified a novel gene which is critical for fetal globin expression. The studies we propose here will further define the function of this gene and assess its potential for gene therapy for sickle cell disease and thalassemia.Read moreRead less
Regulation of the EphA3 receptor tyrosine kinase in vertebrate development. The Eph/ephrin system has a critical role in normal embryonic development. Amongst vertebrates, the EphA3 gene is one of the most highly conserved genes in this system with critical roles in development of the visual system and in other developmental processes. Understanding how this gene is regulated will help us to understand the critical role of EphA3 in the basic biology of humans and other animals. This knowledge ma ....Regulation of the EphA3 receptor tyrosine kinase in vertebrate development. The Eph/ephrin system has a critical role in normal embryonic development. Amongst vertebrates, the EphA3 gene is one of the most highly conserved genes in this system with critical roles in development of the visual system and in other developmental processes. Understanding how this gene is regulated will help us to understand the critical role of EphA3 in the basic biology of humans and other animals. This knowledge may also shed light on the basis of congenital abnormalities and other pathological processes and possibly help us to understand how to prevent or treat these conditions.Read moreRead less
