Abstract

Dasheen mosaic virus (DsMV) is a member of the family Potyviridae, genus Potyvirus, and infects taro (Colocasia esculenta) and other aroids wherever they grow. DsMV infection results in characteristic feathery mottle and mosaic symptoms on leaves and can cause up to 60% production losses on taro and other edible aroids. In June 2012, taro plants showing mosaic, feathery mottle, and yellowing symptoms were observed in a germplasm collection at the Areka Agricultural Research Centre, Wolayita Zone, southern Ethiopia, and leaf samples were collected. Taro plants maintained in the collection were originally obtained from farmer's fields in south and southwest Ethiopia. Results of antigen-coated plate ELISA, double antibody sandwich ELISA, PCR assay, sequencing and BLAST analysis confirmed the presence of DsMV in the infected samples. This is thought to be the first report of DsMV infecting taro in Ethiopia.
