Event Description
- Full Description:
- Join us for our next Centre for Marine Science special seminar, supported by the Institute for Molecular Bioscience and the School of Biological Sciences Monday 26 October 3pm in Room 105 of the Colin Clark Building (39-105).
Professor Debashish Bhattacharya, will be joining us from the Department of Ecology, Evolution, and Natural Resources, Rutgers University.
Abstract: Primary plastid endosymbiosis relied on the establishment of a metabolic connection between the host cell and captured cyanobacterium. We posit these connections were dominated by existing host-derived components. To test this idea, we used phylogenomic and network analysis to infer the evolutionary history of plastid membrane (permeome) transporters from Arabidopsis thaliana and found that 57% are of eukaryotic origin with the captured cyanobacterium making a relatively minor contribution. Ongoing work with the relatively recently acquired plastid in the photosynthetic amoeba Paulinella chromatophora is consistent with these results and will also be discussed. Our results advance understanding of plastid integration and favor a host-centric view of endosymbiosis, whereby genes of eukaryotic or bacterial (non-cyanobacterial) origin provided key elements for establishing metabolic connections in the first algae.
The School of Biological Sciences are hosting a postgraduate lunch with Prof. Bhattacharya for postgraduates in the School. Contact Jude Keyse
