| additional rep-encoding dnas associated with banana bunchy top virus. | banana bunchy top nanovirus (bbtv) has a multicomponent circular single-stranded dna (cssdna) genome consisting of at least six components. we have cloned, sequenced and analysed two additional cssdna components, designated bbtv-s1 and s2, associated with a taiwanese bbtv isolate. the sequences of bbtv-s1 and s2 comprised 1109 and 1095 nucleotides (nt), respectively, and like bbtv dna-1, potentially encoded replication initiation proteins (reps). however, the genome organisation of bbtv-s1 and s ... | 2001 | 11266219 |
| evidence of inter-component recombination, intra-component recombination and reassortment in banana bunchy top virus. | banana bunchy top virus (bbtv; family nanoviridae, genus babuvirus) is a multi-component, ssdna virus, which causes widespread banana crop losses throughout tropical africa and australasia. we determined the full genome sequences of 12 bbtv isolates from the kingdom of tonga and analysed these together with previously determined bbtv sequences to show that reassortment and both inter- and intra-component recombination have all been relatively frequent occurrences during bbtv evolution. we found ... | 2012 | 22278830 |
