TABLE 2.
Estimations of times of divergence for Microcystis strains observed in the 2014 cyanoHABa
| Sequence | Mutation rate (no. of substitutions/site/yr) | Time of divergence (yrs) |
|---|---|---|
| Whole genome | 1.00E−04 | 1.06E+06–1.39E+07 |
| 1.00E−07 | 1.06E+09–1.39E+10 | |
| mcyB | 1.00E−04 | 3.53E+02–1.24E+04 |
| 1.00E−07 | 3.53E+05–1.24E+07 | |
| mcyC | 1.00E−04 | 3.00E+02–1.24E+04 |
| 1.00E−07 | 3.00E+02–1.24E+07 | |

Mutation rates included in this table represent the upper and lower limits of mutation rates found in several bacterial genomes based on an analysis completed by Gibson and Eyre-Walker (40). Times of divergence were calculated for the samples that had the lowest and highest conANI scores for whole genomes and the mcyB and mcyC genes compared pairwise.
