초록

Twelve Cucumber mosaic virus (CMV) isolates were isolated from genetically modified (GM) and non-GM Capsicum annuum in two GM fields, Namyangju and Anseong, and their properties were investigated in this study. Coat protein (CP) gene of the CMV isolates were synthesized by RT-PCR using genus-specific primers which designed to amplify a DNA fragment of 950 bp. Purified cDNA fragments were cloned into the pGEMT easy vector for sequence determination. Nucleotide sequences (internal 657 bp) of CMV isolates were compared with Fny-CMV CP sequences and there were no significant collection site specific sequence similarities found. When predicted amino acid sequences (219 amino acids) were compared with Fny-CMV CP amino acids sequences, there were 96.8% to 97.3% similarities found from Namyangju collections and 95.9% to 96.8% similarities from Anseong collections. The phylogenetic analysis with nucleotide sequences showed definite differences in CMVs which have been isolated from the two regions.
