Using genomic information to understand and improve the quality of the Australian South Sea Pearl. Recently, mass-produced freshwater pearls from Asia have markedly increased in quality and begun to compromise our prestigious South Sea Pearl market. This presents Australian pearlers with a challenge to maintain market identity by improving their pearl quality and consistency. By adding genomics to the existing Australian pearl industry armoury we will help not only to maintain the premier positi ....Using genomic information to understand and improve the quality of the Australian South Sea Pearl. Recently, mass-produced freshwater pearls from Asia have markedly increased in quality and begun to compromise our prestigious South Sea Pearl market. This presents Australian pearlers with a challenge to maintain market identity by improving their pearl quality and consistency. By adding genomics to the existing Australian pearl industry armoury we will help not only to maintain the premier position of the Australian South Sea Pearl in the market, but also to move it further ahead. Knowledge of the genetics of pearl formation will advance a range of hatchery and farm practices, such as selective breeding and pearl grafting, which in turn can enhance farm-based operations and the remote communities that support them.Read moreRead less
Enhancing the Pearl: understanding the molecular genetics of pearl lustre, colour and size. Australia produces some of the most valuable pearls in the world. However recently the world has been flooded with high quality mass-produced freshwater pearls. This has begun to eat into our prestigious South Sea Pearl market and now presents Australian pearlers with a challenge to maintain market identity. We propose to respond this challenge by improving the quality and consistency of the cultured Sou ....Enhancing the Pearl: understanding the molecular genetics of pearl lustre, colour and size. Australia produces some of the most valuable pearls in the world. However recently the world has been flooded with high quality mass-produced freshwater pearls. This has begun to eat into our prestigious South Sea Pearl market and now presents Australian pearlers with a challenge to maintain market identity. We propose to respond this challenge by improving the quality and consistency of the cultured South Sea Pearl through gaining a detailed understanding of how the oyster genetically controls pearl biofabrication - focusing on pearl colour, size and lustre. This information will identify pearl oysters that are a source of high-quality donor mantle tissue and that can be used in selective breeding programs.Read moreRead less
Transcriptional regulation of erythropoiesis. The major expected outcome from this proposal will be development of a pipeline for the study of how transcription factors work at a genome level. There will be national benefit in the areas of Frontier Technologies, and Promoting and Maintaining Good Health. There will be specific outcomes with respect to development of tests for human blood diseases, future design of drugs to target the aberrant activities of transcription factors in genetic and de ....Transcriptional regulation of erythropoiesis. The major expected outcome from this proposal will be development of a pipeline for the study of how transcription factors work at a genome level. There will be national benefit in the areas of Frontier Technologies, and Promoting and Maintaining Good Health. There will be specific outcomes with respect to development of tests for human blood diseases, future design of drugs to target the aberrant activities of transcription factors in genetic and degenerative diseases. Also, a strong bridge will be built upon the previous collaborations of the research teams in Brisbane and Pennsylvania, which will facilitate advanced teaching and training of Australian PhD and post-doctoral scientists.Read moreRead less
The role of epigenetics in the early gestational programming of adult phenotype by ethanol. The concept of foetal programming is changing the way we think about the aetiology of complex disease in adults. Our studies would emphasise that adverse events during pregnancy can have long-term health implications, with concomitant social and economic consequences. In America, the prevalence of foetal alcohol syndrome is comparable with rates for Down syndrome. The Aboriginal community in Australia ....The role of epigenetics in the early gestational programming of adult phenotype by ethanol. The concept of foetal programming is changing the way we think about the aetiology of complex disease in adults. Our studies would emphasise that adverse events during pregnancy can have long-term health implications, with concomitant social and economic consequences. In America, the prevalence of foetal alcohol syndrome is comparable with rates for Down syndrome. The Aboriginal community in Australia has been identified as a high-risk group. The knowledge gained from this project could aid in the development of screening strategies to predict the likelihood of disease developing later in life, providing an opportunity for presymptomatic healthcare.Read moreRead less
The making of a sea shell: function and evolution of genes encoding calcareous architectures of phenomenal strength, purity and beauty. The mollusc shell is composed of microscopic layers of tabular calcium carbonate crystals and thin sheets of proteins with precise nanoscale architectures.

The mollusc shell is composed of microscopic layers of tabular calcium carbonate crystals and thin sheets of proteins with precise nanoscale architectures. This configuration produces a high-performance composite material that exceeds the present capabilities of human engineering. This integrated study will elucidate the molecular mechanisms controlling the fabrication of these architectures. This knowledge will contribute significantly to the development of materials for advanced electronics and energy transducers, human bone therapeutics and marine?based products such as pearls and cements, through the identification of genes underlying biofabrication networks and the development of in vitro bioproduction systems.

Progenitor cells within the peritoneal cavity. Implantation of a foreign object into the peritoneal cavity of animals recruits undifferentiated cells of bone marrow origin that encapsulate the free-floating object, then differentiate into myofibroblasts. When large pieces of myofibroblast capsule tissue are subsequently grafted into autologous artery, bladder or vas deferens, they develop the structure and morphology of that organ. We hypothesise that multipotent progenitor cells sequestered t ....Progenitor cells within the peritoneal cavity. Implantation of a foreign object into the peritoneal cavity of animals recruits undifferentiated cells of bone marrow origin that encapsulate the free-floating object, then differentiate into myofibroblasts. When large pieces of myofibroblast capsule tissue are subsequently grafted into autologous artery, bladder or vas deferens, they develop the structure and morphology of that organ. We hypothesise that multipotent progenitor cells sequestered to the peritoneal cavity can be manipulated to differentiate along smooth muscle and other pathways. The proposed project aims to identify the origin of these cells and characterise the transcriptional program that regulates their differentiation.Read moreRead less
Genetical Genomics of Mutational Variance. Mutation is the ultimate source of all genetic variation. Understanding the nature of mutation, its frequency, the distribution of effects, and the forces of selection that remove mutational load from populations is therefore a central concern of genetics. The accumulation of mutational load both in endangered species and human populations, where the natural forces of selection tend not to operate, has the potential to create serious problems in these p ....Genetical Genomics of Mutational Variance. Mutation is the ultimate source of all genetic variation. Understanding the nature of mutation, its frequency, the distribution of effects, and the forces of selection that remove mutational load from populations is therefore a central concern of genetics. The accumulation of mutational load both in endangered species and human populations, where the natural forces of selection tend not to operate, has the potential to create serious problems in these populations. The goal is to understand what types of mutations are targeted by selection at the gene expression level and why.Read moreRead less
The Genomic Dimensionality of the Response to Natural Selection. Many future advances in agriculture and medicine, as well as an understanding of adaptive evolution in natural and pest populations will require discovering the genes that regulate the expression of complex traits. Microarray technology is at the forefront of modern genomics, but despite its promise, is currently restricted in its utility by significant analytical problems associated with the analysis of the large number of gene ex ....The Genomic Dimensionality of the Response to Natural Selection. Many future advances in agriculture and medicine, as well as an understanding of adaptive evolution in natural and pest populations will require discovering the genes that regulate the expression of complex traits. Microarray technology is at the forefront of modern genomics, but despite its promise, is currently restricted in its utility by significant analytical problems associated with the analysis of the large number of gene expression profiles and their interpretation. Analytical approaches will be developed that will substantially enhance the ability of transcriptional profiling to effectively uncover key genes underlying important phenotypes of interest across the biological and medical sciences.Read moreRead less

The mammalian genome projects have provided a huge leap forward for biological research by giving the framework to study genes on a global scale. This project will provide human genome project scale information for every major tissue in mammals and will provide the research community with a world class resource to further genomic research. It will also investigate parts of gene regulation which have been invisible to researchers in the past. Discovering these rules will provide novel insights in pathology with a genetic component and provide a further boost to biotechnological approaches to obtain expression of specific sets of genes in model systems.
