Lessons learned from the core RNA promoters of Brome mosaic virus and Cucumber mosaic virus.
summary RNA core promoters are nucleotide sequences needed to direct proper initiation of viral RNA synthesis by the viral replicase. Minimal length core promoter-templates that can direct accurate initiation of the genomic plus-, genomic minus-, and subgenomic RNAs of Brome mosaic virus and Cucumber mosaic virus were characterized in previous works. Several common themes and differences were observed in how each of the core promoters directed the initiation of viral RNA synthesis in vitro. These observations are summarized and compared in this short review.
