title: Characterization of a member of a new Potyvirus species infecting arracacha in Brazil.
abstract: An arracacha (Arracacia xanthorrhiza) plant collected in Brazil was found to be infected by a new virus. This viral isolate (named C17) systemically infected Nicotiana benthamiana and Apium graveolens. A polyclonal antibody was raised, and analysis of our arracacha germplasm collection showed a high infection rate of C17-like viruses (93% infection). Sequencing of the ca. 1.7 kb 3'-terminal genomic region revealed a typical potyvirus genome organization. It shared less than 70% nucleotide identity with any other potyvirus sequence, which thus indicated that it is possibly a member of a new Potyvirus species tentatively named Arracacha mottle virus (AMoV).
