Usage

Uses

ent-Kaurenal can be used in biological study of using transmission electronic microscopy and mass spectrometry electron-dense thylakoids of chloroplasts of Stevia rebaudiana leaves during active vegetable growth of the plant in relation to the biosynthesis of diterpenoid glycosides. Particularly, transmission electron microscopy and mass spectrometric analysis identified ent-kauren which is biosynthetic precursor of diterpenoid glycosides and gibberellins in electron-dense thylakoids of Stevia rebaudiana leaf chloroplasts.

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.
