FIG. 3.

Phenotype of C. parasitica colonies infected with mutant viruses. Spheroplasts of C. parasitica strain EP155 were transfected with synthetic transcripts derived from each of the mutant virus cDNA plasmids, Δp29 (3), Δp40a (4), Δp40b (5), Δp69a (6), and Δp69b (7). Virus-free host strain EP155 (1) and wild-type virus (CHV1-EP713)-infected EP155 (2) are also shown. (A) Fungal colonies were photographed after culturing on PDA plates for 6 days. (B) One-month-old cultures of the same colonies were magnified to clearly show formation of conidia-containing pustules.
