—Comparison of different groups of the filamentous prophages found in Neisseria genomes generated with Easyfig (Sullivan et al. 2011). Genes are colored based on function and organization of the Nf1 (MDAφ) presented by Bille et al. (2017). Nf1/Nf3 prophage of Z2491 and Ngoφ6/Ngoφ7 of FA1090 have been described previously (Kawai et al. 2005; Piekarowicz et al. 2006). Filamentous prophages in “other” category were too divergent to align. Replication genes are shown in orange (diagonal lines), genes encoding structural proteins are shown in blue (blocked), assembly and secretion gene is shown in purple, and genes in white (no fill) have no representative in Nf1. Vertical blocks between sequences indicate regions of shared similarity shaded according to BlastN.
