The PVC group is a superphylum of bacteria named after its three important members, Planctomycetes, Verrucomicrobia, and Chlamydiae.[2] Cavalier-Smith postulated that the PVC bacteria probably lost or reduced their peptidoglycan cell wall twice.[3] It has been hypothesised that a member of the PVC clade might have been the host cell in the endosymbiotic event that gave rise to the first proto-eukaryotic cell.[4][5]
Cavalier-Smith calls the same group Planctobacteria and considers it a phylum. However, this is not followed by the larger scientific community.[6] In the Cavalier-Smith bacterial megaclassification, it is within the bacterial Gracilicutes infra-kingdom and comprises the phyla Chlamydiae, Lentisphaerae, Planctomycetes, Verrucomicrobia.[3][7]
