Differential paralog divergence modulates genome evolution across yeast species

Fig 7

Plasmid-borne copies of SUL1 cause a higher fitness benefit than SUL2 in all species except S. uvarum.

A) Schematic describing the strains that were competed against each another in the chemostat. B) The relative fitness of 9 S. cerevisiae strains containing a plasmid with SUL1 and SUL2 alleles from S. cerevisiae, S. paradoxus, S. mikatae, S. uvarum, and N. castellii SUL2. The fitness was measured in the chemostat under sulfate-limited conditions against a GFP-marked lab strain. Each bar corresponds to the mean of 4 or more replicates ±SD with asterisks indicating a p-value <0.05.
