Characterization of CchPV1. (A) Electrophoresis of purified dsRNAs extracted from Cordyceps chanhua RCEF5997 in a 1.5% agarose gel. M, DNA marker; lane 1, dsRNA segments of RCEF5997. (B) Schematic representation of CchPV1. (C) Sequence alignment information of 5’-UTR and 3’-UTR of CchPV1 (ClustalX was used for sequence alignment). An asterisk indicates a position with a single, fully conserved residue. Colons and periods indicate conservation between groups with strongly similar properties (scoring > 0.5) and weakly similar properties (scoring ≤ 0.5), respectively, in the Gonnet PAM 250 matrix.
