Summary
Functional epigenomics interrogation of DNA methylation dynamics during vertebrate development and evolution. DNA methylation (mC) is an epigenetic signal essential for the maintenance of correct gene expression patterns. To investigate the causal relationships between mC and transcription during vertebrate embryonic development and evolution, this project will perform high-resolution mC profiling at different stages of teleost, amphibian and mammalian development.

DNA methylation (mC) is an epigenetic signal essential for the maintenance of correct gene expression patterns. To investigate the causal relationships between mC and transcription during vertebrate embryonic development and evolution, this project will perform high-resolution mC profiling at different stages of teleost, amphibian and mammalian development. Highly conserved and syntenic, methylated sequences will then be used as baits in proteomics screens to identify novel 5mC 'readers'. The generation of genomic profiles of mC 'readers' and their integration with developmental mC maps will reveal transient epigenome dynamics during vertebrate embryogenesis and provide new insights into the conservation of these crucial developmental mechanisms.Read moreRead less
Unique epigenetic states in plant stem cell niches for safeguarding genome integrity. Plant stem cells are the foundation cells of all plant growth and development, including generation of the reproductive cells. Therefore, it is critical that stem cells defend against attacks that may damage the genome. A unique epigenetic state in plant stem cell niches has been discovered that may protect the genome from damage due to parasitic DNA elements. Using sophisticated genomics, genetics, and cellula ....Unique epigenetic states in plant stem cell niches for safeguarding genome integrity. Plant stem cells are the foundation cells of all plant growth and development, including generation of the reproductive cells. Therefore, it is critical that stem cells defend against attacks that may damage the genome. A unique epigenetic state in plant stem cell niches has been discovered that may protect the genome from damage due to parasitic DNA elements. Using sophisticated genomics, genetics, and cellular technologies, this project will investigate how stem cell epigenetic state is linked to genome defence, how environmental stresses can disrupt the defence system, and the role of the system in driving new genetic diversity. This knowledge is of high importance as agricultural crops enter an era of increasingly challenging conditions.Read moreRead less
The roles and regulators of new plant cells linked to root transport. Plant genomics has moved to the single cell resolution, allowing precise investigations of previously hidden cell types and cell states that respond to environmental stress and that vary among differentially adapted plant populations. Here, we will extend our pioneering efforts that have mapped and discovered novel root cell types, to determine their salt and nutrient stress responses, and to elegantly dissect the underling ca ....The roles and regulators of new plant cells linked to root transport. Plant genomics has moved to the single cell resolution, allowing precise investigations of previously hidden cell types and cell states that respond to environmental stress and that vary among differentially adapted plant populations. Here, we will extend our pioneering efforts that have mapped and discovered novel root cell types, to determine their salt and nutrient stress responses, and to elegantly dissect the underling causal genetic variation. The unique cell markers and regulatory networks will be validated with tissue specific and transgenic tools that can work across a host of plant species to reveal adaptive cellular responses to harsh environmental conditions.Read moreRead less
Deciphering the regulation and function of the epigenome in eukaryotic development and stress response. The epigenome is an additional regulatory code superimposed upon plant and animal genomes that controls how they operate. This project will aim to understand the information encoded in the epigenome and how it changes in development and environmental stress, enabling manipulation of its function in crops and correction of its dysfunction in disease.
Comprehensive characterisation of DNA demethylation pathways in vivo. This project aims to provide a better understanding of the roles that DNA methylation plays during embryonic development. DNA methylation is a major regulatory mark present in vertebrate genomes. It is well established that the genomic patterns of DNA methylation are being actively remodelled during vertebrate embryogenesis. Nevertheless, it remains unclear how these events impact gene regulation and embryonic development itse ....Comprehensive characterisation of DNA demethylation pathways in vivo. This project aims to provide a better understanding of the roles that DNA methylation plays during embryonic development. DNA methylation is a major regulatory mark present in vertebrate genomes. It is well established that the genomic patterns of DNA methylation are being actively remodelled during vertebrate embryogenesis. Nevertheless, it remains unclear how these events impact gene regulation and embryonic development itself. This project expects to unravel the functional contributions of DNA methylation to vertebrate embryogenesis by using latest cutting-edge genomics techniques. The project will be carried out on the highly tractable zebrafish model system which allows for easy genetic manipulation of the desired sequences. This project aims to provide a better understanding of embryonic development of vertebrates, including humans.Read moreRead less

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

A walk on the wild side: understanding disease resistance across plants. Plants are in constant battle with pests and pathogens. Wild species host genetic diversity, providing sources of disease resistance, while the narrow genetic base of crop varieties leads to an increasing reliance on the unsustainable application of chemical fungicides. Here I will apply the latest genomics approaches to characterise disease resistance gene diversity across the plant kingdom.

Wild species host genetic diversity, providing sources of disease resistance, while the narrow genetic base of crop varieties leads to an increasing reliance on the unsustainable application of chemical fungicides. Here I will apply the latest genomics approaches to characterise disease resistance gene diversity across the plant kingdom. Comparison of gene diversity within and between plant families will improve our understanding of resistance gene evolution in wild species and the impact of domestication and breeding on resistance gene diversity. Translation of this knowledge will support breeding for crop resilience, leading to durable resistance and more sustainable crop productionRead moreRead less
Transcriptome sequencing and functional characterisation of craniate non-visual sensory systems and their adaptation to diverse light environments. Light detection (photoreception) is critical to species survival. It is not limited to vision, but also serves to set biological rhythms. In mammals, all photoreception is thought to occur solely through the eye, but in non-mammals many other tissues directly monitor light levels. However, the signalling cascades and functional roles of these non-vis ....Transcriptome sequencing and functional characterisation of craniate non-visual sensory systems and their adaptation to diverse light environments. Light detection (photoreception) is critical to species survival. It is not limited to vision, but also serves to set biological rhythms. In mammals, all photoreception is thought to occur solely through the eye, but in non-mammals many other tissues directly monitor light levels. However, the signalling cascades and functional roles of these non-visual pathways are largely unknown. This project will use high-throughput sequencing technologies and functional analyses to trace the origin and function of different irradiance detection systems in each main craniate class. By comparing species from diverse photic habitats, the influence of light as a substrate for adaptation will be investigated.Read moreRead less
