| Biosynthesis of Isoflavonoid Phytoalexins: Incorporation of Sodium |1,2-13C2] Acetate into Phaseollin and Kievitone  | | | | Abstract
| 13C-NMR analysis of the isoflavonoid phytoalexins phaseollin and kievitone produced by feeding sodium [l,2-13C2]acetate to wounded bean (Phaseolus vulgaris) cotyledons has demon strated the incorporation of intact acetate units into the aromatic A rings. Phaseollin shows a specific folding of the polyketide chain, whereas kievitone exhibits a randomisation of label in accordance with the intermediacy of a 2',4',6'-trihydroxylated chalcone during its formation. In neither case was sufficient label incorporated into analysis. | | | |
