Intra- and inter-specific variations of gene expression levels in yeast are largely neutral

ABSTRACT: It is commonly, although not universally, accepted that most intra- and inter-specific genome sequence variations are more or less neutral, whereas a large fraction of organism-level phenotypic variations are adaptive.  Gene expression levels are molecular phenotypes that bridge the gap between genotypes and corresponding organism-level phenotypes.  Yet, it is unknown whether natural variations in gene expression levels are mostly neutral or adaptive.  Here we address this fundamental question by genome-wide profiling and comparison of gene expression levels in nine yeast strains belonging to three closely related Saccharomyces species and originating from five different ecological environments.
