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.
从法国大蕉 cv. Nendran（AAB）中提取病毒 RNA 后，确定了香蕉束顶病毒（BBrMV）印度分离株（TRY）的首个完整基因组序列。该完整基因组长 9711 个核苷酸，不包括 poly(A) 尾巴，其基因组结构与之前表征的菲律宾（PHI）分离株相似。与 BBrMV-PHI 相比，BBrMV-TRY 的完整基因组序列在核苷酸水平上同源性为 94%，其十个成熟蛋白的氨基酸序列同一性范围为 88%至 98%。系统发育分析表明，BBrMV-TRY 分离株与 BBrMV-PHI 分离株密切相关。
