Germinating spores of the fungus Botryodiplodia theobromae incorporated guanine-8-C14 into both the nuclear DNA and mitochondrial DNA fractions. Ethidium bromide inhibited the synthesis of mitochondrial DNA without having a significant effect on nuclear DNA synthesis or on the rate and extent of spore germination. Rates of leucine and uracil incorporation and of oxygen uptake were not significantly affected by ethidium bromide until germination was nearly completed. Mitochondrial DNA synthesis is apparently not required for germination of the spores of B. theobromae but is probably essential to continued vegetative growth.
