Structural comparisons among genomes (chromosome and plasmids) of seed and nodule rhizobial strains. a Rhizobium phaseoli. The genome of the nodule strain CIAT652 was used as a reference for comparisons with seed strains of this species. Predicted open reading frames (ORFs) of seed strains with homology to CIAT652 are indicated: CCGM1 (dark green), CCGM2 (lime), CCGM8 (green), and CCGM9 (yellow). b Strains related to R. leguminosarum. The genome of the nodule strain WSM2304 was used as a reference for comparisons with seed strains of this species. Predicted ORFs of seed strains with homology to WSM2304 are indicated: CCGM4 (dark blue), CCGM5 (lead blue), and CCGM6 (sky blue). c R. grahamii. The genome of the nodule strain CCGE502 was used as a reference for comparison with the seed strain CCGM3. Predicted ORFs of CCGM3 with homology to CCGE502 are shown in red. The homology between a CCGM3 contig (possibly a plasmid) and the CCGE502 chromosome is indicated in orange. For each replicon, different features are indicated starting from the innermost circle, including G + C skew for predicted ORFs, G + C content of ORFs (%; black), and predicted ORFs in the plus or minus strands (turquoise)
