Abstract

A novel mitovirus was detected in taro (Colocasia esculenta) growing in Ningbo, China. The complete genome sequence of Colocasia esculenta associated mitovirus 1 (CeaMV1) was determined by next-generation sequencing combined with RT-PCR and RACE. The genome is 2921 nucleotides long and contains a single ORF encoding a putative RNA-dependent RNA polymerase. Homology searches and phylogenetic analysis suggested that CeaMV1 is a member of a new species in the genus Duamitovirus. This is the first report of a member of the family Mitoviridae associated with taro.
