ButMV-B has a deletion of almost the entire TGB1 reading frame, leaving only a portion of ~14 codons, of which seven codons overlap with the TGB2 initiation codon and reading frame. There are five termination codons downstream of the ButMV-B RdRP termination codon, and in frame with the remaining fragment of the TGB1 reading frame.
