FIG. 2.

Colony morphologies on PDA conferred by parental and chimeric hypoviruses. A colony of virus-free C. parasitica isolate EP155 is shown at the top left (A1). Colonies transfected with parental viruses CHV1-Euro7 and CHV1-EP713 are shown at coordinates A2 and A3, respectively. Colonies infected with chimeric viruses are shown at the following coordinates: R13, A4; R14, A5; R12, B2; R6, B3; R10, B4; R5, B5; R7, C2; R3, C3; R8, C4; and R9, C5. The photograph was taken on day 7 of culture on PDA.
