摘要
A cell-free system prepared from Citrus sinensis exocarp transformed R-[2-C-14]mevalonic acid into abscisic acid, phaseic acid and 1',4'-trans-abscisic acid diol. 1',4'-Trans-abscisic acid diol was unequivocally characterized as the major product of mevalonic acid metabolism in the Citrus cell-free system. The addition of (R,S)-abscisic acid as a <<cold-pool trap>> increased incorporation of radioactivity into putative abscisic acid but reduced the levels of [C-14] associated with 1',4'-trans-abscisic acid diol, negating a role for this metabolite as a precursor to abscisic acid.
