Non-Mendelian inheritance of chaperone gene deletion-induced changes in [PSI⁺] induction efficiency. Diploids generated by mating chaperone deletion stains with a wild-type [psi⁻][pin⁻] strain were sporulated and dissected. The resulting tetrads were analyzed for [PSI⁺] induction efficiency by nonsense suppression assay on −ADE medium. Wild-type strains were mated with hsp104Δ strains to demonstrate genetic specificity for this assay. Wild-type (+) and deletion-carrying (−) haploid progeny are presented. Twenty-four tetrads were analyzed per diploid.
