Comments "By contrast to the TCV [Turnip crinkle virus] situation, packaging of RNA larger than wild type was observed in vitro for Cucumber mosaic virus (CMV), another icosahedral RNA virus whose capsid is 29 nm in diameter (primary source). The packaging scheme for CMV RNAs is identical to that of BMV (Brome mosaic virus, Figure 2C): RNA1 (~3300 nt) and RNA2 (~3000 nt) are packaged separately, whereas RNA3 (~2200 nt) and its sgRNA4 (~1010 nt) are copackaged into a third virion (primary source)." sgRNA=sub genomic RNA
