HHV-6A/B genomes and their integrated forms. Schematic representation of human herpesvirus 6A and 6B (HHV-6A/B) genomes and the reported integrated forms. (A) The unique region (U) of the 160 kbp HHV-6A/B genomes is flanked by identical direct repeats (DRL and DRR) of 8–9 kbp. The DRs possess a pac1 (yellow) and pac2 (red) sequences, adjacent to imperfect telomeric repeats impTMR (blue) and TMR (green) sequences, respectively. The genome is not drawn to scale; (B) Chromosomally integrated HHV-6A/B (ciHHV-6A/B) genome (with loss of pac2 in DRR and pac1 in DRL) with elongated telomeres at the DRL; (C) Single integrated DRL with elongated telomere; (D) Integrated HHV-6A/B concatemers. Genomes are not drawn to scale.
