The first complete genome sequence of an Indian isolate (TRY) of Banana bract mosaic virus (BBrMV) was determined following virus RNA extraction from the French plantain cv. Nendran (AAB). The complete genome was 9711 nucleotides excluding the poly(A) tail and had a genome organization similar to that of a Philippine (PHI) isolate characterized earlier. When compared to BBrMV-PHI, the complete genome sequence of BBrMV-TRY was 94% identical at the nucleotide level and its ten mature proteins had amino acid sequence identities ranging from 88 to 98%. Phylogenetic analysis suggests that the BBrMV-TRY isolate is closely related to the BBrMV-PHI isolate.
