Variation in the BLV provirus. a Screen shot from IGV shows representative reads from a subset of the clones from each BLV-infected animal with a mutation in the first base of codon 303 in the viral protein Tax. Reads were mapped to the BLV proviral reference. Dotted red line shows approximate position within the BLV proviral genome represented below. b Structural variants observed in the BLV provirus. Deletions (blue bars) and duplications (red bars) in BLV proviruses identified in both ovine and bovine samples sequenced by PCIP-seq are represented below the BLV proviral genome
