Cellular determinants of retrotransposition. This project aims to understand the processes that control retrotransposition in a genome. Transposable elements make up more than 50% of human genomes. The accumulation of retrotransposons through millions of years of evolution has shaped the genomes of all eukaryotic organisms, including humans. Researchers have elucidated mechanisms the host uses to defend the genome against insertional mutagenesis by retrotransposons, but the cellular machinery an ....Cellular determinants of retrotransposition. This project aims to understand the processes that control retrotransposition in a genome. Transposable elements make up more than 50% of human genomes. The accumulation of retrotransposons through millions of years of evolution has shaped the genomes of all eukaryotic organisms, including humans. Researchers have elucidated mechanisms the host uses to defend the genome against insertional mutagenesis by retrotransposons, but the cellular machinery and genomic environments needed for retrotransposition are undefined. This project aims to use models to uncover the mechanisms that control retrotransposition. This is expected to reveal more about human origins.Read moreRead less
Mapping recombination blocks in Brassica. DNA technology provides new ways to study genomes. Understanding how the genome behaves during plant breeding will help design strategies for the breeding and selection of improved crop plants.
Genome dynamics following plastid endosymbiosis. Plastid endosymbiosis events (enslavement of an algal cell inside of a host cell to form a plastid) are difficult to pinpoint because the genomic data required for a broad array of species are rarely available. Furthermore, the classical method used to infer endosymbiotic gene transfers is being criticised. This project will elucidate the origin of chlorarachniophyte and dinoflagellate plastids and characterise the genome dynamics following endosy ....Genome dynamics following plastid endosymbiosis.

Furthermore, the classical method used to infer endosymbiotic gene transfers is being criticised. This project will elucidate the origin of chlorarachniophyte and dinoflagellate plastids and characterise the genome dynamics following endosymbiosis. It uses densely sampled genome data obtained with high-throughput sequencing technologies. Simulation studies will be used to evaluate methods for inferring endosymbiotic gene transfer and alignment-free methods will be used to improve phylogenomic pipelines.Read moreRead less
Evolution and function of fragmented animal mitochondrial genomes. This project will reveal why animal mitochondrial genomes are in pieces, and how fragmented mitochondrial genomes evolve and function. This project will discover whether or not fragmented mitochondrial genomes have functional advantages. Knowledge generated from this project will lead to new approaches to mitochondrial genetic diseases in humans.

Evolutionary genomics and origin of the molluscan biomineralisation toolkit. The project aims to use new genomes from understudied lineages of Mollusca to identify the genes involved in shell formation (biomineralisation) and infer their function and evolutionary history. The ability of molluscs to biofabricate intricate and robust skeletal structures from sea water is encoded in their genomes. Understanding the ancestral biomineralisation toolkit is of great interest to materials science, which ....Evolutionary genomics and origin of the molluscan biomineralisation toolkit. The project aims to use new genomes from understudied lineages of Mollusca to identify the genes involved in shell formation (biomineralisation) and infer their function and evolutionary history. The ability of molluscs to biofabricate intricate and robust skeletal structures from sea water is encoded in their genomes. Understanding the ancestral biomineralisation toolkit is of great interest to materials science, which seeks to replicate molluscan biomineralisation in vitro for biomedical and other applications. Understanding the toolkit is an important first step toward synthetic biology techniques to 'print' structures like bones in vitro. Moreover, new genomic resources from molluscs will be of interest to researchers in numerous fields.Read moreRead less
Resolving insect evolution. Our poor understanding of the evolution of insects, life’s most successful group, is a huge gap in our knowledge of nature. By analysing genomic data the project will resolve the insect evolutionary tree and discover what drove insect evolution. This will expand our knowledge of how evolution works - a vital part of conserving our biological diversity.
Development of population-level algorithms for modelling genomic variation and its impact on cellular function in animals and plants. The purpose of this project is to develop mathematical and computational tools which will enable researchers to model high-throughput biological data at the population level. These models will be used to uncover the effect that genetic variation has on the physiology of the cell and the organism.
Defining the Brassica pan-genome and establishing methods for gene conversion based crop improvement. Gene content varies between individual varieties. The project aims to apply novel genomic tools to identify and characterise the fixed and variable gene content in the important crop canola and use this to understand genome evolution as well as develop tools to accelerate canola breeding. The project team have developed and used a high-resolution genotyping approach to demonstrate that gene conv ....Defining the Brassica pan-genome and establishing methods for gene conversion based crop improvement. Gene content varies between individual varieties. The project aims to apply novel genomic tools to identify and characterise the fixed and variable gene content in the important crop canola and use this to understand genome evolution as well as develop tools to accelerate canola breeding. The project team have developed and used a high-resolution genotyping approach to demonstrate that gene conversions, short recombination events which lead to the non-reciprocal exchange of genomic regions during meiosis, are abundant in crop genomes. The project aims to develop methods and resources to characterise gene conversion in canola and establish a basis for gene conversion based crop improvement.Read moreRead less
The characterization of tiny Ribonucleic acids in animal epigenetics. Epigenetics, the inheritance of traits not encoded in deoxyribonucleic acid (DNA), is not well understood in animals. This project will investigate two classes of Ribonucleic acid (RNA) that may form part of an animal-specific epigenetic regulatory system. This study could revolutionize our understanding of animal genetics.
