Figure 2From: Housekeeping genes essential for pantothenate biosynthesis are plasmid-encoded in Rhizobium etli and Rhizobium leguminosarumComparison of phylogenetic trees constructed from core and panCB genes. Maximum-likelihood phylogenetic trees of 16 Rhizobiales constructed using the concatenated nucleic acid sequences of 10 housekeeping genes (a) or panC and panB concatenated genes (b). Bootstrap values are shown over each branch (based on 100 pseudo-replicates).Back to article page
