Serial Endosymbiosis

Cellular evolution from microbes to eukaryotes.

Diatom genomics: genetic acquisitions and mergers

Diatom genomics: genetic acquisitions and merger : Entrez PubMed: "Diatom algae arose by two-step endosymbiosis. The complete genome of the diatom Thalassiosira pseudonana has now been sequenced, allowing us to reconstruct the remarkable intracellular gene transfers that occurred during this convoluted cellular evolution."
