Amino acid neighbor-joining tree of single internal repeats of brg11, hpx17, hax2, and homologues of R. solanacearum strains SD58 (type a), GX526 (type b2), GD52 (type c), FJ49 (type d1), ZJ1993Bn1 (type d2), GX57 and ICPM11121 (type d3), FJP16 (type d4), and UW360 (type e). In total, 123 repeats were analyzed. Similar repeats were grouped. Repeats were numbered according to the position in brg11 +1 to + 9 (from the 5′ end) and −1 to −9 (from the 3′ end). Bootstrap consensus tree, n = 100, PAM.
