FIG. 2.

Neighbor-joining phylogram inferred from analysis of individual pVGC genes, with lineages demarcated by numbered brackets. With the exception of the actA gene tree, which was midpoint rooted, individual gene trees were rooted with L. ivanovii (NRRL 33017 and NRRL 33021) and L. seeligeri (NRRL 33019) sequences (data not shown). The frequency (percent) with which a given branch was recovered in 1,000 neighbor-joining bootstrap replications is shown above branches recovered in >50% of the bootstrap replicates.
