蚕豆染色病毒CPS基因的序列测定及RT-PCR检测方法的建立

 The nucleotide sequence of small coat protein (CPS) gene of Broad bean stain virus (BBSV) was determined and compared with other comoviruses. The CPS gene of BBSV consisted of 687 nucleotides and encodes a putative protein of 228 amino acid residues. The CPS sequence of BBSV and those of other comoviruses shared identities of 36.5%-58.9% and 35.2%-70.3% at the nucleotide and amino acid levels, respectively. The RT-PCR method specific for BBSV detection was developed based on the determined CPS sequence. The RT-PCR assay presented here allows, for the first time, rapid and specific detection of BBSV.

Sequence determination of small coat protein gene of Broad bean stain virus and the development of RT-PCR detection method

The nucleotide sequence of small coat protein (CPS) gene of Broad bean stain virus (BBSV) was determined and compared with other comoviruses. The CPS gene of BBSV consisted of 687 nucleotides and encodes a putative protein of 228 amino acid residues. The CPS sequence of BBSV and those of other comoviruses shared identities of 36.5% -58.9% and 35.2% -70.3% at the nucleotide and amino acid levels, respectively. The RT-PCR method specific for BBSV detection was developed based on the determined CPS sequence. The RT-PCR assay presented here allows, for the first time, rapid and specific detection of BBSV.
