Organization of HCRSV genomic RNA and its corresponding open reading frames and predicted proteins (not drawn to scale).

<p>The upper rectangles represent open reading frames. Untranslated region (UTR); putative transcription factor (PTF); RNA-dependent RNA polymerases (RdRps); movement protein (mp); pathogenesis-related gene (prg); coat protein (CP). The dotted vertical line represents a readthrough codon UAG. The 3-dimensional rectangles below represent the corresponding predicted mature proteins. Basic amino acids K, R, and H represent the mutation sites in the nuclear localization signal (NLS) of p23.</p>
