P97 and P102 gene organization contexts in the M. flocculare and M. hyopneumoniae 7448 genomes. (A) P97 copy 1 ORF cluster organization. (B) P97 copy 2 ORF cluster organization. (C) P97-like ORF cluster organization. The arrows represent the ORFs (not to scale) and indicate the transcriptional direction. The dark-blue arrows represent the P97 ORFs, and the light-blue arrows represent the P102 ORFs. The white arrows represent the ORFs that are at the limits of the OC. The numbers from one through thirteen represent the ORF name and the names of its orthologous as follows: 1- rpsJ; 2- MF1418 and MHP0197; 3- P97 copy 1; 4- P102 copy 1; 5- MF0249 and MHP0200; 6- MF0247 and MHP0106; 7- P102 copy 2; 8- P97 copy 2; 9- gyrB; 10- transposase; 11- pfkA; 12- P102-like; and 13- P97-like.
