Description

Using sweet potato root tissue infected with Ceratocystis fimbriata, the effect of farnesol, nerolidol or geraniol on the incorporation of acetate-2-14C into ipomeamarone and other lipids, and on the production of ipomeamarone and other lipids was examined. Acetate-2-14C incorpration into ipomeamarone and other lipids and the production of the lipids except ipomeamarone were markedly suppressed by the addition of the terpenol. The production of ipomeamrone was unaffected. It was concluded that the marked decrease of acetate incorporation into ipomeamarone in the presence of the terpenol was due mainly to the direct inhibition of the biosynthetic pathway and to a lesser extent to their dilution effect. The inhibitory sites by the terpenol seemed to be localized in at least 2 positions in the biosynthetic pathway of ipomeamarone. After feeding tissue disks with actetate-2-14C in the presence of farnesol or geraniol, either farnesol or geraniol was isolated, and the respective crystalline derivatives were found to be radioactive.
