Molecular characterization and sequence analyses of Banana bunchy top virus infecting banana cultivar Jahaji (Dwarf Cavendish) in Assam, India.

ABSTRACT: Several isolates of Banana bunchy top virus (BBTV) have been reported worldwide. They are members of either the Pacific Indian Ocean (PIO) or the South East Asian (SEA) group. However, there is only one completely sequenced isolate published from the northeastern part of India till date. Therefore, we obtained the complete sequences of all the six genomic components of a BBTV isolate from the northeastern Indian state of Assam. The isolate was named as BBTV-As-JOR, and its genome showed the presence of the reported conserved motifs. Nevertheless, like other Indian BBTV isolate, the major common regions in DNA-R and DNA-U3 of BBTV-As-JOR had deletions of 26 and 36 nucleotides, respectively. Phylogenetic analysis based on 312 sequences of BBTV DNA-R classified BBTV-As-JOR as a member of the
