A virus isolate designated Angelica bushy stunt virus (AnBSV), provisionally representing a new species in the genus Caulimovirus, was discovered in the medicinal plant Angelica dahurica. The complete 8,300-nt genomic DNA of AnBSV had seven putative open reading frames containing conserved domains/motifs, which are typical features of caulimoviruses, and showed the greatest nucleotide sequence identity (74% identity and 27% query coverage) to a lamium leaf distortion virus isolate. Interestingly, the new caulimovirus exists as endogenous pararetroviral sequences in the host plant and is considered to have multiple defective plant genome-integrated copies that may lead to the generation of subgenomic DNA species.
