Protistology and Cell Biology at the Marine Arago Laboratory of Banyuls-sur-Mer (1961-2000): Personal Recollections.
The history of protistology and the introduction of modern methods of unicell observations is described in a large maritime laboratory over a period of forty years by the initiator of this new team. The development of this team and the doctoral theses developed there are described as well as the major discoveries made. The Arago Laboratory, which was then in 1960 a field laboratory mainly devoted to the collection of biological material, becomes a research laboratory specializing in the study of the major fundamental problems which govern life: the organization and expression of the genome, mitotic processes and their nuclear and cytoplasmic components, cell cycle and its regulation as well as molecular phylogeny. The biological models chosen were essentially the dinoflagellate protists in their great variety: autotrophs, heterotrophs, myxotrophs and able of proliferating at sea, thus disrupting their cell cycle. Coupled with the techniques of biochemistry and molecular biology which it was in its infancy, the most advanced observation methods used electron and confocal microscopy often after use of ultra-cold cryopreparations, necessary to preserve the antigenic sites and allow the highlighting new proteins. The dinoflagellate model was then abandoned in favor of unicellular micro-eukaryotes allowing the development of environmental genomics.
