Genome synteny of B. megaterium. The genomes of strains QM B1551 and DSM319 are mostly colinear, but the distribution of isolate-specific genes is not random: gene insertions are rare in a 2-Mbp region around the origin of replication (ori). Each protein of the reference genome plotted on the x axis was used as the query sequence with BLASTP against the y axis subject genome. The N-terminal coordinates of the best hit proteins were plotted. The colors represent the level of similarity of the match, expressed by the BLAST score ratio (48).
