Limited sequence variation in the leader sequence of RNA 4 from several strains of alfalfa mosaic virus.
The sequences of the 5'-noncoding regions of RNA 4 of seven strains of alfalfa mosaic virus were compared. In each case, the coat protein cistron was preceded by a leader sequence of 39 nucleotides (including the initiator codon). At position 26, an A-, G-, or U-residue was found. Otherwise the leader sequences are identical.
