Increase in gene expression by respiratory-deficient mutation.

Abstract excerpt

Respiratory-deficient mutants (rho- cells) of Saccharomyces cerevisiae produced about 10 times as much human (h-) lysozyme as did wild-type strains (rho+ cells) when the GAL10 promoter was used in an expression plasmid with the h-lysozyme gene. Introduction of intact mitochondria into the rho- cells resulted in a significant decrease in the production of h-lysozyme, indicating that the rho- mutation increased the...
