Sporulation levels of different P. parasitica isolates on eds1 mutant lines and wild-type Arabidopsis accessions. Conidiospore suspensions (4 × 10⁴/ml) of each isolate were sprayed onto 2-week-old seedlings. Spores were harvested from leaves and counted after 7 days of incubation (see Methods). For each P. parasitica isolate tested, the genetically susceptible accession is marked with an asterisk and the resistant accession with the corresponding RPP gene. The experiment was repeated on 1-week-old seedlings with similar results.
