Figure 3 Average cell size of 23 strains across eight Saccharomyces species. A) Images of yeast cells at 100x magnification. B) Violin plot showing the distribution of cell size (log cell area in µm2). Average cell size per species is shown at the bottom. The darker the violin plots, the smaller cells are on average. Levels not connected by same letter are significantly different in pairwise Tukey HSD tests after ANOVA of ‘species’ on ‘log cell area’ (F7,1710= 96.12, p < 0.001).
Figure 4 Scatter plot of strain-specific slopes from linear regressions of cell count (obtained from flow cytometry as number of cells per μL) on optical density (obtained from spectrophotometry as OD600) against average strain cell size (log cell area in µm2).
