These functional results are in agreement with the phylogenetic analysis of BMV and related viral sequences and suggest that a similar mechanism of RNA synthesis takes place for members of the alphavirus superfamily. Results herein demonstrate that the endscript directing genomic plus-strand synthesis also interacts with the viral replicase via a mechanism that does not depend on a speciĀ®c preformed RNA structure. An interesting conclusion from our analysis of the BMV genomic minus-strand RNA endscript is that template sequence may regulate the amount of RNA synthesis in a manner independent of replicase-promoter interaction. ./cache/cord-262609-cssgzvus.txt ./txt/cord-262609-cssgzvus.txt
