This project will take advantage of unique Australian plants to investigate the molecular mechanisms and evolutionary shift in flower colour changes. This project expects to advance knowledge on plant specialised metabolism with potential contributions to the floriculture, food and flavour industries.Read moreRead less
Tracking factor footprints to reveal the intricacy and control of translation initiation. Messenger ribonucleic acid (RNA) translation is required for all of life and knowledge of how it works is central to modern life sciences. This project will develop novel ways of studying translation, generating entirely new descriptions of its inner workings that may transform knowledge of gene function and its use in medical and biotechnological processes.
Understanding the evolution of the alternation of generations in the land plant life cycle. This project will investigate the genetic basis and evolution of the land plant life cycle, in which both haploid and diploid phases consist of complex multicellular bodies. The project's findings, which will be made using two model laboratory plants, will be applicable to all plants and will help understand important processes such as pollen and seed production.

Summary
Plant microRNA targeting: defining regulatory factors additional to complementarity. Central to our understanding of microRNA biology is the identification of which genes they target. In plants, high complementarity is regarded as the sole determinant, and drives bioinformatic predictions. However, functional evidence is inconsistent with this, arguing that complementarity alone is insufficient to accurately predict targets. This project uses novel applications of next generation sequencing to c ....Plant microRNA targeting: defining regulatory factors additional to complementarity. Central to our understanding of microRNA biology is the identification of which genes they target. In plants, high complementarity is regarded as the sole determinant, and drives bioinformatic predictions. However, functional evidence is inconsistent with this, arguing that complementarity alone is insufficient to accurately predict targets. This project uses novel applications of next generation sequencing to categorise bioinformatically predicted Arabidopsis targets as either strongly or poorly regulated. These categories will be analysed to determine what factors, in addition to complementarity, are required for strong targeting. The outcomes will impact artificial microRNA design and have important implications for biotechnology. Read moreRead less

This project aims at combining molecular genetics, transcriptome and proteome analysis to identify genes and pathways underlying high light stress tolerance in previously isolated mutants of the chlorophyte Chlamydomonas reinhardtii. Comprehensive profiles of transcriptome-proteome linkage will be constructed without the complications of multicellularity for this unicellular photosynthetic model organism. We will establish a public proteome reference database and provide new microarrays and molecular markers beneficial for research in Chlamydomonas. We expect to advance understanding of high light resistance mechanisms so that it will eventually be applicable to improve productivity in crop plants growing under various environmental stress conditions.Read moreRead less
The Cytochrome P450 Gene Super-family in Drosophila melanogaster; Gene Function and Insecticide Resistance. The cytochrome P450 (Cyp) gene super-family is represented by over 90 sequences in the genome of the vinegar fly, Drosophila melanogaster. To date, four Cyp genes are found to be involved in insecticide resistance. The function of the majority of Cyp genes is unknown. This project will investigate the function and regulation of D. melanogaster Cyp genes, linking the fly's genotype to its ....The Cytochrome P450 Gene Super-family in Drosophila melanogaster; Gene Function and Insecticide Resistance.

To date, four Cyp genes are found to be involved in insecticide resistance. The function of the majority of Cyp genes is unknown. This project will investigate the function and regulation of D. melanogaster Cyp genes, linking the fly's genotype to its phenotype. By studying the effects of Cyp genes on fly survival, Cyp gene expression and regulation, and expressing selected Cyp genes in a yeast expression system, we will enhance our understanding of Cyp gene function and evolution.Read moreRead less

This project aims to uncover a new mechanism that activates gene expression in mammals, which involves unexpected connections between the core components of chromosomes and essential enzymatic machines required for the expression of genes. This project will generate new knowledge on the poorly understood process of how the extensive genomic information of multicellular organisms is selectively chosen to enable the expression of only the required subset of genes. This will revolutionise our understanding of the mechanisms of gene control thereby shaping the field in the future. Significantly, this will allow new ways to manipulate gene expression that will impact biotechnology by providing new efficient ways to produce proteins or RNA. Read moreRead less
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
Nuclear RNA surveillance and its connection to splicing quality control. Due to the error-prone nature of RNA splicing, elaborate quality control processes ensure that only correctly spliced transcripts can leave the nucleus. It has long been known that incorrectly spliced mRNA transcripts are degraded by the nuclear RNA surveillance machinery, but how the RNA quality control machinery is connected to nuclear RNA surveillance is not known. This proposal aims to uncover the connection between the ....Nuclear RNA surveillance and its connection to splicing quality control. Due to the error-prone nature of RNA splicing, elaborate quality control processes ensure that only correctly spliced transcripts can leave the nucleus. It has long been known that incorrectly spliced mRNA transcripts are degraded by the nuclear RNA surveillance machinery, but how the RNA quality control machinery is connected to nuclear RNA surveillance is not known. This proposal aims to uncover the connection between these two important processes and will fill a significant gap in our understanding of how splicing quality control and nuclear RNA surveillance work. The project will also identify sequence features that trigger abortive splicing reactions and will thus help to improve the design of synthetic mRNAs.Read moreRead less
