FIG. 2.

Identification of transcripts encoded by CCV cDNAs. Northern blots were prepared with poly(A)⁺ RNA isolated from CCO cells, either infected with CCV or mock infected. (A) Northern blot probed with a cDNA corresponding to TR3. (B) Northern blot probed with a cDNA corresponding to TR5/6. Lanes: I, RNA isolated from CCO cells infected with CCV in the presence of cycloheximide; Mi, RNA isolated from mock-infected CCO cells. Arrows labeled TR3, TR5/6, TR6, and ut indicate the TR3, TR5/6, and TR6 transcripts and two unnamed transcripts, respectively. Transcript names are based on ORFs encoding the RNAs. Coding capacities of the unnamed transcripts were not determined. The positions and sizes of RNAs in a 0.24- to 9.5-kb ladder are shown on the left.
