FIG. 5.
(A) Summary alignment of M and S segment vRNA and vcRNA genomes of RVF, SFS, and TOS viruses. Note that in each panel, the experimentally identified putative transcription termination signal is boxed. (B) Summary alignment of Punta Toro (PT) and Uukuniemi (UUK) virus M and S segment vRNA and vcRNA genomes indicating the presence of predicted sequence motifs (boxed) found in appropriate genomic locations downstream of each respective stop codon that may play a role in mRNA transcription termination. Note the high nucleotide sequence identity of these predicted motifs with experimentally determined putative transcription termination signals found in RVF, SFS, and TOS viruses. All nucleotide numbering is relative to the virus GenBank entry.
