Epigenetic temperature sensing in plants


Project Description

Our changing climate is already having a dramatic effect on the growth and development of the plants that support our entire civilisation. This is likely to be amplified as we await concerted action on climate change. It is therefore essential that we attempt to understand the mechanisms that enable factors such as increased temperature to affect plant performance. Understanding these mechanisms will allow us to engineer altered responses and thereby mitigate the negative effects. We have used a genetic screen to identify novel components of the mechanism that allows plants to decide when to flower in response to temperature. One of the novel genes that we identified directly links the epigenetic control of gene expression to temperature perception. In this project you will discover the underlying mechanism, identify more components and use our new understanding to engineer plants that respond differently to temperature. In addition, you will explore the biotechnological applications of the mechanism. You will join a collaborative team including plant developmental biologists, virologists and RNA biologists to apply advanced molecular genetic and genomic approaches to study this highly topical global challenge.




Funding Notes

Project is eligible for funding under the Gosden PhD Studentship scheme. The successful candidate will receive a PhD studentship for 4 years, covering fees at UK/EU level and stipend at research council level (£15,009).
Candidates should have/be expecting a 2.1 or above at undergraduate level in a relevant area. If English is not your first language, you will be required to meet our language entry requirements. The PhD is to start in Oct 2020.
