The following information on the NSUI002 genome is shown from the innermost circle: protein-coding genes transcribed clockwise (1st track, blue) and counterclockwise (2nd, blue), common genes that were shared among NSUI002 and all ST28 S. suis isolates, transcribed clockwise (3rd, green) and counterclockwise (4th, green), MGEs (5th, black), and genes in the cps gene cluster (6th, yellow). The common genes in which synonymous and nonsynonymous mutations were detected are shown in the 7th (purple) and 8th (gray) tracks, respectively. The outermost bar graph for the common genes in the 9th track (red) shows the number of pairs in which nonsynonymous mutations were detected. No common gene exhibited a number of pairs more than 15, the maximum value of the graph.
