Genome organization of phage Smp131, phage P2, and P2-like prophages in Stenotrophomonas and Xanthomonas . Colored arrows indicate the directions and categories (denoted below) of the genes. The numbers or letters near the arrows indicate the names or locus_tags of the genes; red numbers indicate the homologues not found in Smp131. Bent arrows indicate the six promoters identified in phage P2 and those predicted for Smp131 by analogy. Abbreviations: P2, Enterobacteria phage P2; Xac306, prophage remnant in X. axonopodis pv. citri 306; Xcc33913, prophage in X. campestris pv. campestris ATCC33913; K279a, prophage in S. maltophilia K279a; KACC10331, PXO99A and MAFF311018, prophages in X. oryzae pv. oryzae strains KACC10331, PXO99A, MAFF311018, respectively.
