Abstract
We demonstrated the infectivity and host adaptation of a viola isolate of Plantago asiatica mosaic virus (PlAMV-Vi) in an asymptomatic host, Nicotiana benthamiana, through long-term serial passages. Serial passaging of a green fluorescent protein-tagged full-length cDNA clone of PlAMV-Vi (PlAMV-ViGFP) in N. benthamiana plants resulted in the appearance of a new virus line inducing leaf-crinkle symptoms, the Leaf Crinkle (LC) line. Virus titers were higher for both in the LC and the 14th passage line(s) of PlAMV-ViGFP compared with the original line. The LC line was found to have seven unique nucleotide mutations that may have contributed to its higher virulence and multiplication rate in N. benthamiana.
