Incompatibility group P1 (IncP-1) plasmid diversity was evaluated based on replication initiator protein (TrfA) phylogeny. A new and highly divergent clade was identified. Replication assays indicated that TrfA of recently discovered IncP-1 plasmids from Xylella fastidiosa and Verminephrobacter eiseniae initiated plasmid replication using cognate or heterologous origins of replication.
