Abstract

Taro reovirus (TaRV) has been reported infecting taro (Colocasia esculenta) in the South Pacific, but information on the virus is limited. Here, we report the genome sequence of a reovirus infecting taro in Papua New Guinea that had 10 genomic segments ranging from 1.1 to 3.9 kilobase pairs (kbp) in length with a total genome length of 26.3 kbp. TaRV was most closely related to rice ragged stunt virus (RRSV) but did not cross-react with RRSV polyclonal antisera. TaRV was not detected in 82 germplasm accessions of taro in Hawaii, or samples collected in American Samoa, Fiji, Guam, Palau, or Vanuatu.
