abstract：:Clones have been constructed containing full-length cDNA copies of PEBV RNA1 and RNA2, flanked by the CaMV 35 S RNA promoter and the nopaline synthase terminator. The clones are infectious when inoculated onto Nicotiana benthamiana plants. Both the viral RNAs and the virus particles were identified in infected plants....
