The biosynthesis of a C19-gibberellin from mevalonic acid in a cell-free system from a higher plant.
Incubation of a cell-free system from immature seeds of Cucurbita maxima Duch. with [(14)C]GA12-aldehyde derived from [(14)C]mevalonic acid in the same system yielded the C19-gibberellin, [(14)C]GA4, in addition to the C20-gibberellins, [(14)C]GA37, [(14)C]GA13 and [(14)C]GA43. (GA-gibberellin).
