FIG. 1.

Transcription map and genome organization of BAV-3. (a) Summary of transcriptional analysis of BAV-3. The schematic diagram of the BAV-3 genome (34,446 bp) is divided into 100 m.u. Arrows above and below the central line represent mRNAs from the r and l strands, respectively. Solid lines represent sequences found in mRNA, broken lines indicate introns, and arrowheads represent poly(A) sites and show the direction of transcription. Each mRNA in L1 to L7 has a TPL spliced to its 5′ terminus (•). Detailed structures of transcripts in E1A and E1B (50), E3 (31) and E4 (38) have been described elsewhere. (b) Summary of the genomic organization of BAV-3. Genes are named as homologs of HAV-2. Arrows show the positions of the ORFs for the indicated proteins.
