The pentacyclic biosynthetic precursor of jasmonic acid, 12‐oxo‐phytodienoic acid, was found to induce synthesis of the major flavonoid, apiin. in cell suspension cultures of Petroselinum crispum . The accumulation of apiin was preceded by an increase in the relative levels of poly (A)* RNAs that code for the flavonoid biosynthetic enzymes phenylalanine ammonia lyase, 4‐coumarate:CoA ligase and chalcone synthase, Poly (A)* RNAs reached maximal levels at approximately 4–6 h after the addition of elicitor while flavonoids continued to accumulate in the cultures for at least 6 days. 12‐Oxo‐phytodienoic acid is the first pentacyclic precursor in the jasmonic acid biosynthetic chain which functions as a signal transducer for phytoalexin induction.
