Comparative analysis of the Nocardioides sp. strain PD653 and PD653-B2 genomes. (A) The region present only in strain PD653 (lower column) is indicated with an asterisk (*). The translocated segments are marked “a.” The regions amplified to confirm that misassembly had occurred are marked “b” and “c” (not to scale). (B) Structure of the locus marked with a red dotted line in panel A. The arrows indicate the sizes, locations, and directions of open reading frame (ORF) transcription. The genes located in the region marked with an asterisk (*) are marked with black arrows, and the genes conserved in both strains are marked with open arrows. The ORF1, ORF2, and ORF3 candidate genes are marked with yellow, azure, and magenta arrows, respectively.
