  • a n is the number of isolates examined.

  • b NT, nontypeable (the isolates do not belong to any known race).

  • c avrPphF is present in races 1, 5, 7, and 9. Most of the nontypeable strains were not taken into account to calculate the percentages; the only exception was the nontypeable strain from Spain, which contained avrPphF.

  • d Race 2 was first described in 1964.

  • e Only three races of P. syringae pv. phaseolicola were distinguished in this work.

  • f Only toxigenic strains were taken into account.
