FIG. 1.
Schematic presentation of the BRSV ATue51908 genome (drawn to scale). The locations of transcripts (shaded bars) and protein-encoding frames (open bars) are shown relative to the viral RNA (vRNA) (solid bar). In the enlargements, the organizations of recombinant viruses and ATue51908 are compared. The 3′-terminal 45-nt BRSV leader regions are marked by horizontal stripes, and the 44-nt HRSV A2 leader regions are marked by vertical stripes. Genetic tags (NotI) and nucleotide deletions in the NS1 noncoding regions (shaded) of the recombinant viruses are indicated. The relative positions of corresponding nucleotides are given for the gene starts of NS1, NS2, and N and nucleotides flanking the NS2 deletion. The overall lengths of the vRNAs are shown on the right.
