Fitness Effects of Cis-Regulatory Variants in the Saccharomyces cerevisiae TDH3 Promoter.

Abstract excerpt

Variation in gene expression is widespread within and between species, but fitness consequences of this variation are generally unknown. Here, we use mutations in the Saccharomyces cerevisiae TDH3 promoter to assess how changes in TDH3 expression affect cell growth. From these data, we predict the fitness consequences of de novo mutations and natural polymorphisms in the TDH3 promoter. Nearly all mutations and...
