The expression of the Chlamydomonas reinhardtii cytochromeChlamydomonas reinhardtii cytochrome c gene was studied at the steady-state mRNA level. The inclusion of acetate under illumination produced a marked increase in cytochrome c transcripts. This effect was not affected by two inhibitors of mitochondrial energy metabolism. Three different obligate photoautotrophic mutants with defective mitochondria showed normal levels of induction, suggesting that utilization of acetate for respiration is not required for this process. Light, in the presence or absence of acetate, also promoted an increase in cytochrome was not affected by two inhibitors of mitochondrial energy metabolism.
