Epistatic buffering of fitness loss in yeast double deletion strains

Lukasz Jasnos & Ryszard Korona

Interactions between deleterious mutations have been insufficiently studied, despite the fact that their strength and direction are critical for understanding the evolution of genetic recombination and the buildup of mutational load in populations. We compiled a list of 758 yeast gene deletions causing growth defects (from the Munich Information Center for Protein Sequences database and ref.
