Adaptation to High Ethanol Reveals Complex Evolutionary Pathways (original) (raw)
Fig 3
Haploid lineages diploidized during adaptation to EtOH.
Flow cytometry analysis of DNA content (stained by propidium iodide) of evolved populations, compared to ancestral haploid (red) and diploid (blue). For the clonal ancestral samples, two peaks are observed, corresponding to the G1 and G2 phase of the cell cycle. Evolved populations sometimes display three peaks, indicative of both haploid and diploid subpopulations.
