| genetic diversity of banana bunchy top virus isolates from china. | banana bunchy top virus (bbtv) (the genus babuvirus, the family nanoviridae) is a single-stranded circular dna virus with a genome composed of six components designated as dna-r, -u3, -s, -m, -c, and -n. this study analyzed the nucleotide identities of the dna-r of 23 isolates from banana-producing provinces of china, including guangdong, hainan, guangxi, and yunnan. results showed that the nucleotide identity of dna-r was 72.3-100%. phylogenetic analysis indicated that these bbtv isolates were ... | 2017 | 28523929 |
