Comparison of MARTX loci in the X. nematophila, X. bovienii and X. innexi genomes. Schematic representations of loci containing MARTX protein domains (A, B, and C repeat regions and an effector domain region) in X. nematophila ATCC19061, X. bovienii SS-2004, and X. innexi HGB1681. Taller boxes represent open reading frames (locus tags indicated below each), color-coded according to the predicted product, and shorter boxes indicate MARTX subdomains (A, B, and C repeats; indicated with hatching, and effector domains, indicated with color-coding). In functional MARTX proteins the A domain has 14 repeats, the two B domains have 38 (1–38) and 3 (39–41) repeats respectively, and the C domain has 15 repeats. In X. innexi missing repeats from within these domains are noted with the symbol
