*HRSV, human respiratory syncytial virus.
†Nucleotide annotations for leader and trailer region, and for indicated HRSV genes from the first nucleotide of the gene start signal [GGGGCAAAT(A/G); GGAGCAAAAT in case of the L gene] through the last adenosine residue of the gene end signal [AGT(T/A)A(T/A/G)(A/T)(A/T)(A/T)A_n].
