Superphylum of bacteria
The PVC superphylum is a superphylum of bacteria named after its three important members, Planctomycetota , Verrucomicrobiota , and Chlamydiota .[ 2] [ 3] Cavalier-Smith postulated that the PVC bacteria probably lost or reduced their peptidoglycan cell wall twice.[ 4] 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.[ 5] [ 6]
Cavalier-Smith calls the same group Planctobacteria and considers it a phylum . However, this is not followed by the larger scientific community.[ 7] In the Cavalier-Smith bacterial megaclassification, it is within the bacterial Gracilicutes infra-kingdom and comprises the phyla Chlamydiota , Lentisphaerota , Planctomycetota , Verrucomicrobiota .[ 4] [ 8]
