Estimation of absolute genome size data of Arabidopsis taxa
| N | 1Cx-value (pg) (SD) | Expected genome size | Calculated genome size 1 | |
|---|---|---|---|---|
| Arabidopsis thaliana (Columbia) (2×) | 4 | 0.173 (0.010) | 135 Mbp(1) | (1)set as reference |
| Arabidopsis croatica (2×) | 2 | 0.225 (0.007) | 176 Mbp | |
| Arabidopsis arenicola (2×) | 4 | 0.260 (0.008) | 203 Mbp | |
| Arabidopsis lyrata (2×) (Europe) | 4 | 0.270 (0.005) | 210 Mbp | |
| Arabidopsis lyrata (2×) (North America) | 8 | 0.274 (0.007) | 207 Mbp(2) | 214 Mbp |
| Arabidopsis lyrata (4×) | 4 | 0.238 (0.005) | 371 Mbp | |
| Arabidopsis halleri ssp. halleri (2×) | 10 | 0.266 (0.010) | 207 Mbp | |
| Arabidopsis halleri ssp. gemmifera (2×) | 6 | 0.270 (0.004) | 211 Mbp | |
| Arabidopsis kamchatica (4×) | 2 | 0.235 (0.007) | 367 Mbp | |
| Arabidopsis arenosa (4×) | 6 | 0.237 (0.005) | 370 Mbp | |
| Arabidopsis cebennensis (2×) | 22 | 0.281 (0.010) | 219 Mbp | |

Genome sizes measured as 1Cx-values in pg. Arabidopsis thaliana was used as absolute reference of genome size (1135 Mbp, TAIR: http://www.arabidopsis.org) with standard deviation (SD) provided. All genome size data were extrapolated as haploid genome size (1C) accordingly to achieve absolute genome sizes in Mbp. Arabidopsis lyrata from North America served as second and independent control since its genome has been also sequenced and fully annotated 2(207 Mbp [46]). Ploidy level is given in brackets after the respective taxon name. (N: number of individuals analyzed).
