Planctobacteria

The PVC group is a superphylum of bacteria named after its three important members, Planctomycetes, Verrucomicrobia, and Chlamydiae. Cavalier-Smith postulated that the PVC bacteria probably lost or reduced their peptidoglycan cell wall twice. 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.
