This incredible electron cryotomography video highlights many of the intricate features that characterize the subcellular organization of magnetosomes in AMB-1. As the video moves through a cell magnetosomes and the filaments surrounding them are highlighted. We then see the organization of the chain within the cell. In AMB-1 magnetosomes are clearly invaginations of the inner cell membrane providing a mechanism for integrating the magnetic organelle into the cell structure. Detailed results relating to this video can be found in Komeili, Li, Newman and Jensen, Science 2006). Video by: Dr. Zhuo Li and Professor Grant Jensen.
