Circular view of whole genome alignments of bradyrhizobial genomes. Genomes were aligned to a reference genome [for (A) ORS278, (B) ORS285, (C) STM3843, (D) USDA110)]. The localization of aligned genomes is given as a list from inner to outter circles in the center of each figure. Legend (from inner to outter layer of circles: genome scale (kb), GC deviation (gray), GC skew (orange), aligned genomes (aligned parts are in blue, each layer is a different genome, strains are listed close to the reference genome name in the center of each figure, from inner to outer layers), GI (purple), core genome (red), specific genes to reference genomes (pink). Higher resolution images for each genome analysis are available in Supplementary Figure S4.
