摘　　要： dsRNA segment Ⅴ was separated from Bombyx mori cytoplasmic polyhedrosis virus(BmCPV)of Chinese Guangzhou strainAfter ligation with a ssDNA adaptor,the cDNA fragments overlapping full-length segment Ⅴ of BmCPV were acquired by RT-PCR amplificationSegment Ⅴ is 2852 nucleotides long and possesses a single open reading frame encoding a putative protein of 881 amino acidsComparison of amino acid sequences shows 97% homology with BmCPV Japanese isolate segments Ⅴ,86% and 36% with LdCPV-1 and LdCPV-14 segments Ⅴ respectivelyPart of sequence of BmCPV segment Ⅴ exhibits high homology with 2Apro motif of picornavirus members,which may suggest that there might exist some affinities evolutionally between both of dsRNA segment Ⅴ was separated from Bombyx mori cytoplasmic polyhedrosis virus(BmCPV)of Chinese Guangzhou strainAfter ligation with a ssDNA adaptor,the cDNA fragments overlapping full-length segment Ⅴ of BmCPV were acquired by RT-PCR amplificationSegment Ⅴ is 2852 nucleotides long and possesses a single open reading frame encoding a putative protein of 881 amino acidsComparison of amino acid sequences shows 97% homology with BmCPV Japanese isolate segments Ⅴ,86% and 36% with LdCPV-1 and LdCPV-14 segments Ⅴ respectivelyPart of sequence of BmCPV segment Ⅴ exhibits high homology with 2Apro motif of picornavirus members,which may suggest that there might exist some affinities evolutionally between both of them
