摘要
The gene of RNA-dependent RNA polymerase(RdRP) was cloned by RT-PCR from Sugarcane yellow leaf virus-Fuzhou isolate(CHN-FJ1) and then cloned into pMD18-T vector.The sequence showed that the fragment comprised 1 212 nucleotides including part gene of ORF1 and ORF2.The ORF2 was involved the RdRP gene consisted of 995 nucleotides and encoded putative protein of 331 amino acids.Compared the nucleo-tide sequence and encoded putative protein of CHN-FJ1 with the other isolates from different countries,they shared the homology above 92.0%.Phylogenetic tree suggested that the sixteen isolates were classified into four types according to the amino acid sequence of the RdRP.One of the groups contained CHN-FJ1 and the other isolates from China,American,Brazil,Australia and Colombia;however,there was the closest relation between CHN-FJ1 and BRA-YL1 isolate from Brazil.
