A genome-activating N-terminal coat protein peptide of alfalfa mosaic virus is able to activate infection by RNAs 1, 2 and 3 but not by RNAs 1 and 2. Further support for the messenger release hypothesis.
An N-terminal genome-activating peptide of 25 amino acid residues of alfalfa mosaic virus coat protein was unable to activate the incomplete viral genome consisting of RNAs 1 and 2. The messenger release hypothesis predicts that RNA 3 must complement such an inoculum in order to produce RNA 4 that will trigger the process. This is shown indeed to be the case.
