Fitness effects of S. uvarum strains harboring additional copies of SUL alleles.

A) Schematic describing the strains that were competed against one another in the chemostat. B) The relative fitness of four strains of S. uvarum containing an additional integrated copy of either SUL1 or SUL2 from S. cerevisiae or S. uvarum was determined. The fitness was measured in the chemostat under sulfate-limited conditions against an isogenic GFP-marked strain. Each bar corresponds to the mean of 6 replicates ±SD.
