- Abstract
The near full-length genome consisting of four segments of dsRNA from a chrysovirus infecting Korean Cryphonectria nitschkei BS122 strain (CnV1-BS122) was sequenced. The open reading frames of segments 1, 2, 3, and 4 were 2,889, 2,721, 2,475, and 2,232 nucleotides (nt) in length, respectively. Sequence analysis and homology searches of the amino acid sequences deduced from the ORFs of each segment revealed that segments 1, 2, 3, and 4 encoded RNA-dependent RNA polymerase, capsid protein, a putative cysteine protease, and replication-associated protein, respectively. The entire 5′ ends of segments 1, 2, and 4 were 82, 242, and 698 nt in length, respectively; the sequence of the 5′ end of segment 3 was not determined because of difficulty in amplification. The entire 3′ end of segment 3 was 77 nt in length. Partial amplification of the 3′ ends of segments 1, 2, and 4 yielded amplimers of 7, 17, and 30 nt, respectively.
