Acorbate- and glutathione-regulated expression of mitochondrial genes in the rml1, vtc1 and vtc2 mutants. (a) Expression changes in genes encoding components of the respiratory electron transfer chain. The colour bar below each group indicates the location of the encoded protein as illustrated in diagram (c). (b) Ascorbate- and glutathione-regulated changes in the expression of genes encoding other mitochondrial proteins. (c) Schematic of the respiratory electron transfer chain. (a) and (b): black bars, rml1; grey bars, vtc2; white bars, vtc1.
