| Abstract: | Ralstonia solanacearum biovar N2 strains isolated in Asia were compared by biochemical tests with biovar N2 strains from South America and biovar 2 (race 3) strains from Africa, America, Asia and Europe. Distinct differences were found between Asian and South American strains of biovar N2, and between Asian biovar N2 and biovar 2 strains with respect to their ability to utilize several carbon sources. Using cluster analysis based on repetitive sequence‐based polymerase chain reaction (rep‐PCR) genomic fingerprints, the Asian biovar N2 strains were divided into two groups, group 1 containing Japanese strains and group 2 containing Indonesian and Philippine strains. The fingerprints showed the genetic diversity of biovar N2 strains in Asia. |
