Using venoms to map critical and evolutionary conserved vulnerabilities. We have developed and applied new functional genomic approaches to study venom evolution. Using CRISPR screening, we find that unrelated venoms act on cells by exploiting the same vulnerabilities. By functionally mapping these vulnerabilities for all venom classes, we can begin to develop universal venom antidotes. Conversely, much of what we know about venom mechanisms comes from a small percentage of the biodiversity with ....Using venoms to map critical and evolutionary conserved vulnerabilities. We have developed and applied new functional genomic approaches to study venom evolution. Using CRISPR screening, we find that unrelated venoms act on cells by exploiting the same vulnerabilities. By functionally mapping these vulnerabilities for all venom classes, we can begin to develop universal venom antidotes. Conversely, much of what we know about venom mechanisms comes from a small percentage of the biodiversity within a venom, and we have developed genomic tools to study the venom “dark matter”. This work will lead to the full molecular characterisation of venom biodiversity, and new venom components will be useful for research or as novel medicines.Read moreRead less
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
Evolution and specificity of alternative splicing in plants. This project aims to elucidate fundamental principles of alternative splicing, a basic mechanism that plays a vital role in several biological processes across all organisms. Plants are highly effective in adapting to varied environmental, seasonal and climatic conditions and this project aims to uncover how alternative splicing contributes to regulation of gene expression in response to developmental and environmental cues. Uncovering ....Evolution and specificity of alternative splicing in plants. This project aims to elucidate fundamental principles of alternative splicing, a basic mechanism that plays a vital role in several biological processes across all organisms. Plants are highly effective in adapting to varied environmental, seasonal and climatic conditions and this project aims to uncover how alternative splicing contributes to regulation of gene expression in response to developmental and environmental cues. Uncovering the underlying mechanisms of alternative splicing will not only advance fundamental knowledge, but also has the potential to provide tools and technologies through which sensitivities of plants to environmental stress can be potentially manipulated to benefit agriculture.Read moreRead less
Understanding specificity and flexibility in coral symbioses. This project aims to understand why some corals can switch algal partners while others remain faithful to a single strain. This is important because corals depend on their symbiotic algal partners for survival and because some algae provide greater resilience to environmental stress than others. This project will greatly enhance our understanding of the molecular and physiological factors governing flexibility and specificity in coral ....Understanding specificity and flexibility in coral symbioses. This project aims to understand why some corals can switch algal partners while others remain faithful to a single strain. This is important because corals depend on their symbiotic algal partners for survival and because some algae provide greater resilience to environmental stress than others. This project will greatly enhance our understanding of the molecular and physiological factors governing flexibility and specificity in coral-algal symbioses. It will provide much-needed knowledge required to identify associations most appropriate for specific conditions, prioritise populations for conservation, and assess the feasibility of new approaches to managing and restoring coral reefs.

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.
Improving access to phylogenomic resources for under-resourced species: a new look at existing tools. This project will have an impact on our understanding of how to most effectively use existing genomic resources to benefit a wider range of species and to better design new genomic resources. By doing so, improved access to genomic resources will be provided to species that currently have few options.
Breaking the nexus: more biomass in cereal grain. Grain yield is controlled by complex, regulated genetic networks or quantitative trait loci (QTLs) derived from natural variations in many crop plants. Yield is a product of the three major parameters: panicle number, grain number and grain size, trade-offs are commonly observed between grain number and size. There is evidence to suggest it is possible to improve grain size without altering overall biomass. With the genomic and genetic resource t ....Breaking the nexus: more biomass in cereal grain. Grain yield is controlled by complex, regulated genetic networks or quantitative trait loci (QTLs) derived from natural variations in many crop plants. Yield is a product of the three major parameters: panicle number, grain number and grain size, trade-offs are commonly observed between grain number and size. There is evidence to suggest it is possible to improve grain size without altering overall biomass. With the genomic and genetic resource tools at hand. This project will elucidate the genetic architecture of grain size, and manipulate the key loci to generate more biomass in the grain, minimising or eliminating the adverse impact on seed number. This will maximise harvestable yield without imposing increased demand for water and nutrients.Read moreRead less
