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.
Gene-environment interactions in reptile sex determination. Sex in many reptiles-crocodiles, marine and freshwater turtles, lizards, tuatara-depends on temperature in the nest. This project will examine poorly understood interactions between genes and temperature in determining sex expanding knowledge of how reptiles with temperature dependent sex determination can evolve to accommodate environmental change.
Discovering sex determining genes in a reptile with genetic and environmental sex determination. Reptile sex determination is particularly fascinating because it is triggered either by genes on sex chromosomes or by the nest temperature. This project will identify and characterise candidate sex determining genes in a model reptile to understand how genes control sexual differentiation and how they interact with temperature.
Was an ancient bird-like sex chromosome system ancestral to reptiles and mammals? Recent discoveries reveal amazing similarity in the sex chromosomes of distantly related animals. This project will use advanced DNA technology to explore diverse sex chromosomes in reptiles to discover whether this signifies ancient and unsuspected common ancestry, or the convergent redeployment of genes and chromosomes predisposed to determine sex.
Early evolution of the endomesoderm gene regulatory network. This project aims to unravel the endomesoderm gene network’s evolutionary history by identifying its conserved components’ target genes in the calcareous sponge Sycon. Little is known about the evolutionary origin of the developmental gene regulatory networks active in the development of all Eumetazoans (animals with nerves and digestive systems). Sponges are key models to study the transition from protists to eumetazoans, and gene exp ....Early evolution of the endomesoderm gene regulatory network. This project aims to unravel the endomesoderm gene network’s evolutionary history by identifying its conserved components’ target genes in the calcareous sponge Sycon. Little is known about the evolutionary origin of the developmental gene regulatory networks active in the development of all Eumetazoans (animals with nerves and digestive systems). Sponges are key models to study the transition from protists to eumetazoans, and gene expression data supports homology between sponge and eumetazoan tissues and body plans. This project could illuminate the evolutionary history of the animal body plan.Read moreRead less
Sex determination in dragons: Genetics, epigenetics and environment. This project aims to discover the master sex-determining gene in a reptile, how that gene is differentially regulated in males and females and by temperature, and to identify evolutionary drivers of transitions between genetic and environmental sex determination. In many reptiles, like mammals, chromosomes determine sex. In others, the temperature at which their eggs are incubated determines sex. This project will study how tem ....Sex determination in dragons: Genetics, epigenetics and environment. This project aims to discover the master sex-determining gene in a reptile, how that gene is differentially regulated in males and females and by temperature, and to identify evolutionary drivers of transitions between genetic and environmental sex determination. In many reptiles, like mammals, chromosomes determine sex. In others, the temperature at which their eggs are incubated determines sex. This project will study how temperature reverses chromosomal sex determination in dragon lizards. This could show how climatic extremes affect the biology of climate sensitive reptiles, and understand their vulnerability to climate change.Read moreRead less
DNA methylation in insect social evolution. This project will investigate the evolutionary relationship between DNA methylation and the advanced sociality displayed by bees, ants and wasps. The project will map DNA methylation across the social insects and test whether it has coevolved with sociality. It will also determine how a vital social cue, the queen pheromone, influences the worker methylome. Finally, it will apply quantitative genetic and methylomic methods to wild insects, revealing pa ....DNA methylation in insect social evolution. This project will investigate the evolutionary relationship between DNA methylation and the advanced sociality displayed by bees, ants and wasps. The project will map DNA methylation across the social insects and test whether it has coevolved with sociality. It will also determine how a vital social cue, the queen pheromone, influences the worker methylome. Finally, it will apply quantitative genetic and methylomic methods to wild insects, revealing patterns of selection and inheritance in epigenetic and phenotypic traits. By combining genomic and evolutionary methods, the project will advance the ongoing debate about the importance of methylation to sociality and extreme phenotypic plasticity. It will contribute to a quantum leap in our understanding of DNA methylation and sociobiology and mark the first application of quantitative genetics to wild insects.Read moreRead less
Role of Musashi in the regulation of cell cycle proteins. We have identified a protein family that directs cell fate and maintains male fertility. This project will provide new avenues for generation of contraceptives in male animals and to regulate stem cells for production of specialised cell types in biotechnological applications.
How ribosomal protein loss affects cell fate. This project aims to challenge the dogma that the ribosome behaves only as a ‘‘house-keeper’’. Ribosomal protein (RP) mutations should, and often do, result in reduced cell growth and stunted animal development. Depletion of RPs in Drosophila blood cells impair stem cells and cause massive tissue overgrowth. This suggests RPs are involved in cell fate determination, which this project will research using genetic models. As ribosomal function is funda ....How ribosomal protein loss affects cell fate.

Depletion of RPs in Drosophila blood cells impair stem cells and cause massive tissue overgrowth. This suggests RPs are involved in cell fate determination, which this project will research using genetic models. As ribosomal function is fundamental to the development of all living organisms, this work could have wide implications for understanding all biology – from microbes, insects and plants to humans.Read moreRead less
Variation in the arginine vasopressin 1a receptor (AVPR1a) gene, the social environment, general health and wellbeing. The project aims to investigate how the arginine vasopressin 1a gene affects gene expression and influences social behaviour and ultimately health and wellbeing. This research will contribute to understanding the importance of individual differences in social policy and interventions aimed at improving health and wellbeing.
