Characteristics of genes/open reading frames (ORFs) between invH and mutS genes in Gene Cluster 1 of S. Newport SL254 and Gene Cluster 2 of strain from chicken_MO.

Differences between Gene Cluster 1 and 2 demonstrated the mosaic genomic structure around mutS gene. Transposase and integrase were found in both sequences, indicating that both of them could be the hot spots for recombination events. The genes in both S. Newport SL254 and strain from chicken_MO are ordered top to bottom as their synteny on bacterial chromosome from 5′ to 3′.
