Multiple alignment of the sequence, phylogenetic tree, and prediction of HpaXpm structure. a Multiple sequence alignment of HpaXpm with other members of the Xanthomonas Hpa1 group, and the secondary structure of HpaXpm. For the multiple alignment of the amino acid sequence of HpaXpm and of other Hpa1 of Xanthomonas, CLUSTALW was used. The secondary structure of HpaXpm was predicted using the I-TASSER server. b A maximum likelihood bootstrap tree derived from the amino acid sequences of Xanthomonas Hpa1 proteins using the MEGA 6.0 program. Protein accession numbers are indicated after each harpin. Harpin abbreviations: Xag, X. axonopodis pv. glycines; Xcm, X. citri pv. mangiferaeindicae; Xpm, X. phaseoli pv. manihotis; Xac, Xanthomonas axonopodis pv. citri; Xm, X. citri subsp. malvacearum; Xoc, X. oryzae pv. oryzicola; Xoo, X. oryzae pv. oryzae; Xcv, X. campestris pv. vesicatoria. c Ribbon representation of the 3-D structure of HpaXpm using the I-TASSER server. Residues involved in the α-helix are highlighted in red. Stretch-1: 41–64 EKQLDQLLTQLIIMALLQQSNNAE. Stretch-2: 81–109 NQQAGQSNGSPSQYTQMLMNIVGDILQAQ
