Satellite tobacco mosaic virus RNA: structure and implications for assembly
Abstract
The initial appearance of 45% of the single-stranded RNA of satellite tobacco mosaic virus in electron density maps suggested the entire RNA conformation could be delineated. Subsequent work has localized nearly 80% of the RNA as stem-loop elements. Connection of the stem-loops in the most efficient manner produces a persuasive model for the encapsidated RNA. This arrangement has significant implications for virus assembly and for the essential role of RNA.
