Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
The Annals of Botany Annual Oxford Lecture
For both plants and animals, the transition of a fertilised egg cell into a zygote is a critical step in sexual reproduction. In animals, early embryonic divisions rely on maternally provided gene products, whereas in plants, zygotic genome activation occurs before the first embryonic division. Using a rice model, transcription factors encoded by the paternal genome can be shown to play a key role in this triggering this transition. Manipulation of the corresponding genes in eggs bypasses fertilisation and results in parthenogenesis. When combined with editing of meiosis genes, plants that reproduce stably as genetic clones can be generated. With these gene alterations, hybrid rice propagated through seeds maintains uniform hybrid vigour in subsequent generations. Fixation of hybrid vigour in crop plants has broad implications for the availability of high-yielding hybrid seeds at low costs for subsistence farmers.
