FIGURE 2

Phenotype characterization of the wild type and its mutant isolates. (A) Disease symptoms at 11 days post-inoculation (dpi) on Westar and 01-23-2-1 cotyledons inoculated with water, wild type isolate (UMAvr7) and the mutant isolate (umavr7). (B) Pathogenicity tests between wild type isolate and mutant isolate on susceptible (Westar) and resistant genotype (01-23-2-1), respectively. Each bar indicates the mean and standard deviation of lesion size for isolate on certain Brassica napus genotypes. The asterisk over bars represents the significant difference (p < 0.05) of lesion size caused by the wild type and mutant isolate.
