Panicum mosaic virus (PMV) is a single-stranded positive-sense RNA virus in the family Tombusviridae. PMV genomic RNA (gRNA) and subgenomic RNA (sgRNA) are not capped or polyadenylated. We have determined that PMV uses a cap-independent mechanism of translation. A 116-nucleotide translational enhancer (TE) region on the 3′-untranslated region of both the gRNA and sgRNA has been identified. The TE is required for efficient translation of viral proteins in vitro. For mutants with a compromised TE, addition of cap analog, or transposition of the cis-active TE to another location, both restored translational competence of the 5′-proximal sgRNA genes in vitro.
