Figure 2 Slopes of eight Saccharomyces species extracted from regressions of cell counts (obtained from flow cytometry) on optical density (OD600). Slopes are averaged across strains within species and expressed as the cell count increasing per OD600 unit. Bars represents 95% confidence intervals from regression of all data per species. Levels not connected by same letter are significantly different. The species’ phylogenetic relationship is shown at the bottom.
