Understanding somatic mutation in plants: new methods, new software, new data. Somatic mutations accumulate as plants grow, affecting everything from short-term ecological interactions to long-term evolutionary dynamics. These mutations have important consequences for plant industry and conservation, but because they are so hard to measure almost nothing is known about them. This project aims to develop new methods and software to detect, analyse, and compare the genome-wide history of somatic m ....Understanding somatic mutation in plants: new methods, new software, new data. Somatic mutations accumulate as plants grow, affecting everything from short-term ecological interactions to long-term evolutionary dynamics. These mutations have important consequences for plant industry and conservation, but because they are so hard to measure almost nothing is known about them. This project aims to develop new methods and software to detect, analyse, and compare the genome-wide history of somatic mutation in individual plants, providing an unprecedented level of detail into an important but understudied source of biological variation. By applying these methods to an iconic experimental population, This project aims to provide the first insights into the genome-wide causes and consequences of somatic mutation in plants.Read moreRead less
Elucidating the genetic basis of newly evolved metabolic functions in yeast. Elucidating the genetic basis of newly evolved metabolic functions in yeast. This project intends to research how complex metabolic pathways originate and evolve. This project will use cutting edge genome sequencing and molecular techniques to elucidate the heritable genetic basis of Baker’s yeast, which has been the selectively evolved to use xylose as a sole carbon source: something vital for second generation biofuel ....Elucidating the genetic basis of newly evolved metabolic functions in yeast. Elucidating the genetic basis of newly evolved metabolic functions in yeast. This project intends to research how complex metabolic pathways originate and evolve. This project will use cutting edge genome sequencing and molecular techniques to elucidate the heritable genetic basis of Baker’s yeast, which has been the selectively evolved to use xylose as a sole carbon source: something vital for second generation biofuel production that wild yeast cannot do. This project will combine detailed molecular characterisation of highly adapted yeast strains with a novel "molecular palaeontology" approach to trace the evolutionary process and identify functionally significant loci under selection. Detailed characterisation of this trait will accelerate the development of future yeast strains and test fundamental evolutionary theories.Read moreRead less
The role of RNA editing by the brain-specific enzym ADAR3 in learning and memory. Higher-order cognition sets us apart from other species but how this is achieved is still under debate. The project will test the idea, strongly supported by recent genomic analyses, that subtle changes in the sequences of RNA in response to environmental stimuli underpin this extraordinary ability.

Summary
The contribution of histone post-translational modifications to eukaryotic evolution. By comparing the complete DNA sequence of closely related species, it is possible to identify changes in DNA that account for the diversity between these species. The project will use this approach to ask whether DNA changes that influence how DNA itself is packaged into cells have contributed to the evolution of new yeast species.
The role of toxin biosynthesis for marine dinoflagellates - an evolutionary ecological approach. Dinoflagellates are a group of microalgae that include coral symbionts and phytoplankton. Many species produce potent toxins that can be a problem in the aquaculture industry. This project will use novel genetic methods to investigate the evolution and ecology of toxin production in a variety of marine dinoflagellates.
Can lateral gene transfer lead to ecological innovation in eukaryotes? The role of saxitoxin in the diversification of Alexandrium. This project will determine the processes that led to the acquisition and diversification of the genetic basis for a potent neurotoxin, saxitoxin. This project will determine its impact on the evolution of the marine producing organisms and investigate novel genetic methods of toxin detection.
