摘要: To investigate the prevalence and genetic variation of grapevine fanleaf virus (GFLV) in China, 142 grapevine samples from 13 provinces and regions were tested using DAS-ELISA, RT-PCR, and nested RT-PCR. Of the samples, 38 % tested positive for GFLV by DAS-ELISA, and 26.8 % tested positive by RT-PCR and nested RT-PCR. Movement protein (MP) and coat protein (CP) gene PCR products were cloned and sequenced. The MP or CP nucleotide and protein sequences shared identities that ranged from 94.9 % to 100 %. Phylogenetic analysis revealed that Chinese GFLV isolates obtained in this study were distinct from the isolates reported in GenBank.
