The complete nucleotide sequence of the genomic RNA of the NL4 strain of Bean common mosaic virus (BCMV-NL4) was determined. The viral genome is 10037 nucleotides in length, excluding the 3’ terminal poly (A) tail, and contains a single open reading frame (ORF) of 9666 nucleotides encoding a polyprotein of 3222 amino acids. The ORF is flanked by 5’ and 3’ untranslated regions (UTRs) of 133 and 235 nucleotides, respectively. Comparative analyses of the predicted BCMV-NL4 polyprotein with other species of the genus Potyvirus revealed nine cleavage sites resulting in ten functional proteins. Nucleotide and amino acid sequence identities indicated a close relationship between BCMV-NL4 and BCMV-NL1. Blast comparisons using coat protein (CP) and 3’UTR sequences showed 100% identity between BCMV-NL4 and the Mexican variant (US6) of this strain.
