^aFor the F and L genes and the noncoding region between the F and M2 (F/M2), the nucleotide position is numbered from the 3′ end of the negative-sense RNA (GenBank accession no. AF371337). For CDS, the position is the protein position from the N terminus. Underlining indicates the nucleotide changes resulting in a mutated amino acid. F, fusion protein; L, large polymerase protein; M2, putative protein with a molecular mass of 22 kDa; NL/1/00, wild-type strain NL/1/00; Ins, insertion.
