Abstract

Summary

Clover yellow mosaic virus (CYMV) protein encapsidates its RNA at pH 7.5, low ionic strength and at a temperature of 25 °C. Protected RNA fragments extracted from the initiation complexes contained the cap structure mGpppGp in the stoichiometric proportions expected for fragment sizes. These results were consistent with the location of the initiation site for assembly at or near the 5′ end of RNA; consequently, the maturation process is polar (5′ to 3′ direction). This strengthens the case for polar initiation as an alternative to internal initiation in the assembly of helical plant viruses.
