Detection of Tobacco rattle virus (TRV) in Phryma leptostachya L.: A New Native Plant Host in Minnesota

Abstract

To our knowledge, this is the first report of TRV infection in P. leptostachya. The repeated isolation of TRV from plants in isolated, uncultivated habitats suggests that TRV may be endemic to North America. Further studies are needed to determine if infected native perennial plants could serve as a potential TRV reservoir that could cause corky ringspot infection in potato.
