From: Bioinformatic analysis suggests that the Orbivirus VP6 cistron encodes an overlapping gene
Nucleotide frequencies for segment 9. Nucleotide frequencies in 60 nt running windows along each Orbivirus segment 9 RefSeq. 'A' – red, 'C' – green, 'G' – blue, 'U' – purple. Horizontal black bars represent the locations of the VP6 CDS and ORFX (the grey bar represents ORFXb in SCRV). Except for SCRV, the sequences are A- or AG-rich, but they also have an A-rich peak just upstream of ORFX.
