Identification and molecular characterization of Taro bacilliform virus and Taro bacilliform CH virus from East Africa.

ABSTRACT: Taro (Colocasia esculenta) and tannia (Xanthosoma sp.) are important root crops cultivated mainly by small-scale farmers in sub-Saharan Africa and the South Pacific. Viruses are known to be one of the most important constraints to production, with infections resulting in severe yield reduction. In 2014 and 2015, surveys were conducted in Ethiopia, Kenya, Tanzania and Uganda to determine the identity of viruses infecting taro in East Africa. Screening of 392 samples collected from the region using degenerate badnavirus primers revealed an incidence of 58-74% among the four countries surveyed, with sequence analysis identifying both Taro bacilliform virus (TaBV) and Taro bacilliform CH virus (TaBCHV). TaBCHV was identified from all four countries while TaBV was id
