Figure 6. Loss of PdeH leads to reduced pathogenicity on host plants.
Pathogenicity assays on barley leaf explants and rice seedlings. Rice seedlings (cultivar CO39) were spray inoculated with conidia from the wild type, pdeHΔ or pdeLΔ (as described in Materials and Methods) and disease symptoms scored after 9 d. Barley leaf explants were spot inoculated in triplicate with the specified number of conidia (per inoculation site) from the wild type, pdeHΔ or pdeLΔ and disease symptoms scored after 7 days.
