Characterization and genetic status of Banana bunchy top virus isolated from Okinawa, Japan
Journal of General Plant Pathology 71 (1), 68-73
Abstract: Isolates of Banana bunchy top virus (BBTV), which causes bunchy top disease in bananas, were collected in field surveys on seven islands in Okinawa Prefecture, Japan. From 44 banana samples, one isolate from each island was selected, and the DNA-1 and DNA-3 components were sequenced. Analysis of the major common region of DNA-1 showed that BBTV in Okinawa belongs to the Asian group of BBTV. DNA-1 and DNA-3 analysis revealed that Okinawan BBTV had a closer relationship with isolates from Taiwan and the Philippines than with some isolates from China and Vietnam. All the Okinawan BBTV isolates had high homology in the nucleotide sequences of DNA-1 and DNA-3 (%) because of a single, recent BBTV invasion of this area.
