Figure 4. S. cerevisiae GAL alleles confer a fitness advantage in 2.5% glucose medium supplemented with galactose.

Figure 4

a) Growth of S. bayanus strains harboring S. cerevisiae alleles of all seven GAL genes, and the wild-type species, inoculated into medium containing 2.5% glucose and 10% galactose. b) Each bar reports the difference in maximum growth rate between the indicated species and wild-type S. bayanus from a. Error bars report standard error of the mean, and asterisks indicate rates significantly different (p < 1 X 10−8, Wilcoxon rank-sum) from wild-type S. bayanus. c) GAL gene expression at the timepoint indicated by the arrow in a. d-e) In each panel, the first bar reports sugar concentration in medium before inoculation; the remaining bars report sugar concentrations in medium after growth timecourses in a.
