The transgenerational effect of thermosensing in plants. This project aims to understand how thermosensing mechanisms in plants result in transgenerational change, and potentially adaptation to climate. Exploiting the recent discovery of the thermosensor phytochrome B, this project will decipher the molecular cascade which, either through long-distance communication or through persistence of an epigenetic state in the cell lineage, could lead to a trans generational memory in plants helping with ....The transgenerational effect of thermosensing in plants. This project aims to understand how thermosensing mechanisms in plants result in transgenerational change, and potentially adaptation to climate. Exploiting the recent discovery of the thermosensor phytochrome B, this project will decipher the molecular cascade which, either through long-distance communication or through persistence of an epigenetic state in the cell lineage, could lead to a trans generational memory in plants helping with climate adaptation. This project will unravel novel molecular mechanisms, which have the potential to pave the way for designing new climate-proofing solutions to cope with temperature uncertainty.Read moreRead less
The role of epigenetic modifications in bovid adaptation to environmental change. This project will explore the role of epigenetic change, where gene expression is regulated without changing the deoxyribonucleic acid (DNA) sequence, in how animals adapt to rapid climate change. This project will trace epigenetic markers in ancient bison and cows through 30,000 years of climate change, and identify key adaptive genes for the cattle industry.

Summary
Beyond genes: How the extended genotype of plants facilitates adaptation. Adaptation to environmental change is required for species to persist, however rapid environmental change may exceed the limits of traditional genetic adaptation leading to widespread decline. Recent work has highlighted the 'extended genotype' as an additional factor influencing adaptive phenotypes. This project aims to examine DNA methylation and polyploidisation as both a cause and consequence of the adaptation process ....Beyond genes: How the extended genotype of plants facilitates adaptation. Adaptation to environmental change is required for species to persist, however rapid environmental change may exceed the limits of traditional genetic adaptation leading to widespread decline. Recent work has highlighted the 'extended genotype' as an additional factor influencing adaptive phenotypes. This project aims to examine DNA methylation and polyploidisation as both a cause and consequence of the adaptation process using natural populations of the model cereal Brachypodium distachyon. The project aims to determine the architecture of these features and how their variability impacts adaptive traits such as flowering time. From the functional role of the extended genotype the project endeavours to predict and select genetic responses to the environment.Read moreRead less
