Nucleotide sequences of segments 1, 3 and 4 of the genome of Bombyx mori cypovirus 1 encoding putative capsid proteins VP1, VP3 and VP4, respectively.
The complete nucleotide sequences of genomic segments S1, S3 and S4 from Bombyx mori cypovirus 1 (BmCPV-1) have been determined. The segments consisted of 4190, 3846 and 3262 nucleotides encoding putative proteins of 1333, 1239 and 1058 amino acids with molecular masses of approximately 148, 140 and 120 kDa (p148, p140 and p120, respectively). All segments possess a single open reading frame. Homology searches showed that all three proteins have homologies to proteins of Rice ragged stunt virus, a member of the genus Oryzavirus within the family REOVIRIDAE: Partial homologies of p140 to structural proteins in other viruses were also found. The predicted molecular masses and the homologies with structural proteins in other viruses lead us to suggest that S1, S3 and S4 encode the capsid proteins VP1, VP3, and VP4, respectively, of BmCPV-1.
