Pairwise Average Nucleotide Divergence and Polymorphisms in Sulfolobus acidocaldarius and S. islandicus among Core Genomes
| Genome Comparisons | Average Pairwise Nucleotide Divergence | Number of SNPs | Species | Sampling Locations | Reference |
|---|---|---|---|---|---|
| Comparisons among all 47 S. acidocaldarius strains from YNP 2012 | 5.91 × 10−5 | 119 | S. acidocaldarius | YNP (2012) | This study |
| DSM 639 vs. N8 | 3.70 × 10−6 | 9 | S. acidocaldarius | YNP (1972) vs. Japan | Mao and Grogan (2012) |
| N8 vs. Ron12/I | 1.30 × 10−5 | 30 | S. acidocaldarius | Japan vs. Germany | Mao and Grogan (2012) |
| Ron12/I vs. DSM 639 | 1.66 × 10−5 | 38 | S. acidocaldarius | Germany vs. YNP (1972) | Mao and Grogan (2012) |
| Comparisons among Yellowstone strains | 2.60 × 10−3 | S. islandicus | YNP | Reno et al. (2009) | |
| Comparisons between North American strains | 4.60 × 10−3 | S. islandicus | YNP vs. LNP | Reno et al. (2009) | |
| Comparisons between each North American and Mutnovsky strain | 1.11 × 10−2 | S. islandicus | YNP/LNP vs. Mutnovsky | Reno et al. (2009) |
Note.—We identified SNPs using breseq (see “Materials and Methods” section) and calculated average nucleotide divergence as the number of polymorphisms divided by the core genome size. YNP, Yellowstone National Park; LNP, Lassen National Park.
