a
All the acidothermophilic organisms from the family Sulfolobaceae have spacers matching those of the rudiviral genomes. However, the neutrophilic hyperthermophiles S. marinus and H. butylicus produced very few matches. Matches at the amino acid sequence level that overlapped with those at the nucleotide sequence level were excluded from the data.
b
Numbers in parentheses in columns 2 and 3 indicate the number of matches that arose from spacers shared by S. solfataricus strains P1 and P2 (16).
