Role of mRNA polyadenylation control in gene expression. Several benefits would come from a more complete understanding of the function of the messenger RNA poly(A) tail. It is frequently targeted by mechanisms that control cellular protein synthesis. This is most evident in developmental biology, where tail length control regulates maternal mRNA expression. Our previous work suggests that it has much wider importance for cellular function than previously thought and thus its study will produce ....Role of mRNA polyadenylation control in gene expression.

This is most evident in developmental biology, where tail length control regulates maternal mRNA expression. Our previous work suggests that it has much wider importance for cellular function than previously thought and thus its study will produce knowledge of broad relevance to modern life sciences and its applications in medicine and biotechnology. Finally, a better understanding of yeast cellular biology is of benefit to the food and biotechnology sector of industry.Read moreRead less
Application of genome-wide transcriptional analysis to identifying genetic markers for industrial fermentation processes. This project aims to identify yeast genes involved in the response of commercial strains to stress, to determine their role in fermentation and the genetic pathways through which they operate. The ultimate goals are to determine the impact on fermentation activity of stress, and to develop predictive methods for assessing such conditions. This has significance since stress ....Application of genome-wide transcriptional analysis to identifying genetic markers for industrial fermentation processes. This project aims to identify yeast genes involved in the response of commercial strains to stress, to determine their role in fermentation and the genetic pathways through which they operate. The ultimate goals are to determine the impact on fermentation activity of stress, and to develop predictive methods for assessing such conditions. This has significance since stress during fermentation represents a significant commercial loss. The outcomes of this work will be a better understanding of how yeast responds to stress, and the identification of genes that can be used by the commercial partner to monitor and ensure fermentation efficiency.Read moreRead less
Determining the sequence of events during eukaryotic translation initiation. Multiple benefits will arise from a more complete understanding of translation initiation. It is a frequent target for mechanisms that control gene expression and its dys-regulation is associated with human disease. For example, this is evident in cancer biology, since altered translation is a frequent cause of tumorigenesis. Translation is of universal importance for cellular function and knowledge of how it works is c ....Determining the sequence of events during eukaryotic translation initiation.

Summary
Developmental Imaging Facility. This application seeks to establish a facility to undertake expression profiling in vertebrate tissues on a genomic scale and at the highest resolution. Undertaking large scale projects of this nature requires specialised robotics and dedicated infrastructure for microscopy and tissue preparation. This facility will be the first of its type in Australia will permit researchers to perform genomic scale in situ screens, many as part of large international initiative ....Developmental Imaging Facility. This application seeks to establish a facility to undertake expression profiling in vertebrate tissues on a genomic scale and at the highest resolution. Undertaking large scale projects of this nature requires specialised robotics and dedicated infrastructure for microscopy and tissue preparation. This facility will be the first of its type in Australia will permit researchers to perform genomic scale in situ screens, many as part of large international initiatives in developmental and cellular biology. This large-scale, high-resolution expression profiling infrastructure is required to maintain international competitiveness and will dramatically improve our gene discovery, functional assessment and understanding of vertebrate development.Read moreRead less
Function and redundancy of SOX genes in the mammalian sex determination pathway. We are studying a mouse model of abnormal sex organ development in which genetically female mice develop as males. Our basic research program will lead to greater understanding of the genetic switch controlling the formation of male and female characteristics. This research should in turn provide insight into the causes of defects in patients with disorders of sex development, helping to inform the difficult clinica ....Function and redundancy of SOX genes in the mammalian sex determination pathway. We are studying a mouse model of abnormal sex organ development in which genetically female mice develop as males. Our basic research program will lead to greater understanding of the genetic switch controlling the formation of male and female characteristics. This research should in turn provide insight into the causes of defects in patients with disorders of sex development, helping to inform the difficult clinical decisions that need to be made for their treatment, and ultimately leading to better management and therapeutic strategies. Our studies may also provide unique methods to control the exotic mouse population, using the daughterless strategy.Read moreRead less
Specification of the nerve cell subtypes in the developing central nervous system. Different subtypes of nerve cells in the brain, which carry out distinct functions, are generated in the embryo by the co-ordinated action of many genes. This project aims to use the genetic advantages of the zebrafish to determine the role of genes in specifying the final fates of nerve cells in the retina, which analyses visual signals within the eye.
Elucidating the neural pathways and genetic basis of speech. The project will elucidate the biological basis of speech, a unique feature of the human condition. The project will do this by i) discovering genes associated with speech disorder and ii) defining the neural pathways associated with speech production. This study will address critical questions regarding gene, brain and behaviour relationships in speech.
Structure and function of a new class of multi-zinc finger (MZF) transcriptional regulators. An understanding of how genes are switched on and off during the development and lifetime of an organism is central to developing the ability to fight many diseases in a rational way. This project will advance our knowledge in this area at a fundamental molecular level by examining the mechanisms through which a specific set of proteins controls gene expression.
