Detection and genetic variation analysis of grapevine fanleaf virus (GFLV) isolates in China

Detection and genetic variation analysis of grapevine fanleaf virus (GFLV) isolates in China 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals

Abstract

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.
