BIOSYNTHESIS OF GIBBERELLIN A12-ALDEHYDE, GIBBERELLIN A12 AND THEIR KAURENOID PRECURSORS FROM MEVALONIC ACID IN A CELL-FREE SYSTEM FROM IMMATURE SEED OF PHASEOLUS COCCINEUS

A cell-free system capable of gibberellin (GA) biosynthesis has been prepared from immature seed of Phaseolus coccineus.This system converted mevalonic acid (MVA) to ent-kaurene, ent-kaurenoic acid, ent-kauradienoic acid, ent-7α-hydroxykaurenoic acid, ent-6α,7α-dihydroxykaurenoic acid, GA12-aldehyde and GA12. ent-Kaurene was converted to ent-kaurenol, ent-kaurenal, ent-kaurenoic acid and ent-7α-hydroxykaurenoic acid.All identifications were by GC/MC.The pathway from MVA to GA12-aldehyde in this species thus appears to be the same as that found in cell-free preparations derived from immature seed of other species.Key Word Index-Phaseolus coccineus; Leguminosae; runner bean; seed development; biosynthesis; cell-free system; HPLC; GC/MC; gibberellin.
