Sackler Colloquia banner

 Symbioses becoming permanent:
 The origins and evolutionary
 trajectories of organelles

October 15-17, 2014; Irvine, CA
Organized by W. Ford Doolittle (Dalhousie University), Patrick Keeling (University of British Columbia), and John McCutcheon (University of Montana)
Co-sponsored by Canadian Institute for Advanced Research


This colloquium has a goal of filling the gap between ‘endosymbiont’ and ‘organelle’ by identifying two experimental areas, Genome Evolution, and Integration and Control, where substantial advances have been made in both endosymbiont and organelle systems, but where the full potential of these advances has not been met due to the absence of a comparative framework. The Genome Evolution theme will address issues of genome reduction and the relationship between genomic architecture and sequence evolution. The Integration and Control theme will focus on processes through which two previously independent evolutionary individuals come to work together, such as gene flow, protein trafficking, signaling and transporters.
