- Abstract
Banana bunchy top virus (BBTV) is a multi-component single-stranded DNA virus. From 267 potentially infected Musa plants, 24 apparently 'defective' BBTV components have been identified. Interestingly, 23/24 of these defective molecules were apparently derived from DNA-R. All of the identified defective molecules had retained at least part of the CR-SL and CR-M but had insertions and/or deletions that in most cases resulted in open reading frame disruptions. Our detection of three monophyletic but diverse (and therefore likely circulating) defective DNA-R lineages suggests that, in many cases, defective DNA-R molecules might remain associated with BBTV genomes for prolonged periods.
