Figure 3From: Genome-wide deletion mutant analysis reveals genes required for respiratory growth, mitochondrial genome maintenance and mitochondrial protein synthesis in Saccharomyces cerevisiaeClasses of pet mutants. The left column indicates genotypes of haploid pet mutant strains taken from the deletion library carrying a deletion in the nuclear genome (Δyfg1, 'your favourite gene 1') and either no mtDNA ([rho0]; alternatively these strains might be [rho-]) or a wild type-like mitochondrial genome ([rho+]; labeled in red). The middle column indicates genotypes of heterozygous diploid strains after mating with Δmip1. The right column indicates genotypes of haploid deletion mutants after having received [rho+] mitochondria from a donor strain by cytoduction. Respiratory-competent mitochondria are labeled in red, and respiratory-competent yeast cells are depicted on a red background. Class I mutants contain either [rho+] or [rho0] or [rho-] mitochondria after cytoduction. See text for details.Back to article page
