OxTalks is Changing
OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Antisense transcription and epigenetic switching: lessons from FLC
How is gene expression quantitatively regulated? Through the study of how plants perceive and respond to winter, we have discovered that Arabidopsis FLC is an excellent system in which to mechanistically dissect how non-coding transcription and chromatin structure quantitatively regulate gene expression. In the warm, an antisense-mediated chromatin mechanism coordinately influences transcriptional initiation and elongation. With increasing cold exposure, FLC is epigenetically silenced through a conserved Polycomb switching mechanism. The talk will describe our latest understanding of this regulation and how it has been modulated during adaptation.
