PCR amplification of mutant alleles from spv
strains. Agarose gel electrophoresis of PCR products was performed by
using the F6-R6 (lanes 1 to 5) and F5-R5 (lanes 6 to 10) sets of
gum-specific primers with genomic DNA from X.
oryzae pv. oryzae strains. Lanes: 1 and 6, BXO112; 2 and 7,
BXO119; 3 and 8, BXO123; 4 and 9, BXO121; 5 and 10, BXO125. The
molecular size marker (lane M) is a BstEII digest of lambda
DNA.
