Farnesol, geranylgeraniol, dolichols and ubiquinones were the main radioactive components of the unsaponifiable lipid recovered from Phytophthora cactorum grown in aerated cultures containing [2-(14)C]mevalonate. The (14)C recovered in each of these components was in the approximate proportion 2:4:3:5. When the culture was not aerated no radioactive ubiquinone was recovered. Most of the (14)C r...
