Incorporation of all-trans-farnesol into sterols and ubiquinone in Nicotiana tabacum L. cv Bright Yellow-2 cell cultures

Feeding of E,E-[1-3H] farnesol to Nicotiana tabacum L. cv Bright Yellow-2 cells demonstrated large incorporation of the radioactivity into free sterols, the predominant end products of the mevalonate pathway. All the individual sterols, including cholesterol, were found to be labeled. Farnesol radioactivity was also detected in the prenyl side-chain of ubiquinone Q10.
