Molecular characterization of banana streak virus isolate from banana cultivar Kanchi kela of ABB genotype.

摘要

Banana streak virus (BSV) is an important virus of banana and plantain ( Musa spp.) throughout the world. A survey was conducted for the occurrence of BSV in banana plantation around Pune, India. The virus has been molecularly characterized, sequenced and designated as BSV-Pune isolate. It was detected by PCR amplification in symptomatic samples. The isolate originated from banana cv. Kanchi kela. The sequence was compared with those of BSV reported previously. The BSV-Pune sequence was homologous to that of BSV-K3, sharing 100% identity, but was distinct from BSV-Uganda A isolate.
