Detection of SIRV1 viral DNA in S. solfataricus CRISPR spacers. A. Log-pygram of S. solfataricus CRISPR ranging from coordinates 1,809,680 to 1,815,570. Each lens shows a single spacer surrounded by the peculiar S. solfataricus conserved repeats forming the CRISPR units. For the sake of clarity, the main CRISPR constituents (leader, unit and spacer) and orientation (thick black arrow) have been sketched above the pygram. B. Log-pygram of the SIRV1 genome sequence. Each lens displays the repeats, containing from 21 to 31 nucleotides, located in the CRISPR spacers of S. solfataricus.
