Alignment of the genomic island PPHGI-1 from P. syringae pv phaseolicola 1302A

(Accession # AJ870974) with similar islands in PSA strains CFBP7286 (Italy), CH2010-6 (China), and MAFF302091 (Japan). Genomic regions of PSA strains were aligned with PPHGI-1 using BLASTN and visualized using the Artemis comparison tool [56]. Positions of PCR products that distinguish the island present in strain CH2010-6 and MAFF302091 from the island present in strain CFBP7286 are indicated by two yellow and one orange rectangle respectively. content differences within the islands of strains CFBP7286 and CH2010-6 compared to the MAFF302091 genome are listed in Table S5.
