Nucleotide sequence of the brome mosaic virus genome and its implications for viral replication.
The nucleotide sequences of brome mosaic virus (BMV) RNAs 1 (3234 bases) and 2 (2865 bases) have been determined, completing the primary structure of the 8200 base tripartite BMV genome. cDNA clones covering 99% of BMV RNA1 and a full-length cDNA clone of BMV RNA2 were isolated in the course of this work. Extensive sequence homology and known interaction with several proteins suggest that the 3' ends of the BMV RNAs are the major regulatory regions of the genome. Smaller regions at the 5' ends of RNAs 1 and 2 show strong homology to each other and lesser homology to RNA3. These and other features of the sequences are discussed in relation to replication, regulation and evolution of the BMV genome.
