Résumé
Large and giant DNA viruses are a monophyletic group constituting the recently established phylum Nucleocytoviricota. The virus particle morphogenesis of these viruses exhibit striking similarities. Viral factories are established in the host cells where new virions are assembled by recruiting host membranes, forming an inner lipid layer. An outer protein layer starts as a lamellar structure, commonly referred to as viral crescents, coded by the major capsid protein gene. Also, these viruses have a conserved ATPase-coding gene related to genome encapsidation. Similar properties are described for tectiviruses, putative small ancestors of giant viruses. Here we review the morphogenesis of giant viruses and discuss how the process similarities constitute additional evidence to the common origin of Nucleocytoviricota.
