Propagation of PRV encoding carboxy-terminal truncations in VP1/2. (A) Alignment of the predicted amino acid sequences of the VP1/2 carboxy termini from 10 alphaherpesviruses. Sites of three PRV truncation mutations are indicated. (B) Detection of infected cells by GFP-capsid fluorescence at 3 days posttransfection with the corresponding infectious clone.
