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 |
bioinformatic analysis of bbtv satellite dna in hainan. | banana bunchy top virus (bbtv), family nanaviridae, genus babuvirus, is a single stranded dna virus (ssdna) that causes banana bunchy top disease (bbtd) in banana plants. it is the most common and most destructive of all viruses in these plants and is widespread throughout the asia-pacific region. in this study we isolated, cloned and sequenced a bbtv sample from hainan island, china. the results from sequencing and bioinformatics analysis indicate this isolate represents a satellite dna compone ... | 2011 | 21847760 |
cloning and sequence analysis of two banana bunchy top virus genomes in hainan. | the genome of banana bunchy top virus (bbtv) consists of six segments of single-stranded dna of approximately 1 kb in length. we identified and sequenced the complete genomes of two bbtv isolates, one with and one without satellite dna, from haikou, hainan, china. the haikou-2 isolate contains six genomic segments and an additional satellite dna while the haikou-4 isolate contains only six genomic segments. typical of other babuviruses, each genomic segment encodes a single open reading frame an ... | 2012 | 22286609 |
