Organization of the RSV genome. RSV consists of four RNAs: RNA1, RNA2, RNA3, and RNA4. Viral-sense RNAs and viral-complementary sense RNAs are abbreviated vRNA and vcRNA, respectively, with the corresponding RNA number. The black line indicates the length of nucleotides for each RNA, and the colored rectangular represents the corresponding ORF with the predicted protein size. The sizes (in bp) of 5′, 3′, and intergenic regions are also indicated. The name of each protein is as follows: RdRp in RNA1; P2 (silencing suppressor) and PC2 (glycoprotein) in RNA2; and P3 (nonstructural protein, NS3), PC3 (nucleocapsid protein, CP) in RNA3; P4 (nonstructural disease-specific protein, SP), and PC4 (movement protein, MP) in RNA4.
