Metabolism of Gibberellins in Immature Seeds of Pisum sativum

Part of the Proceedings in Life Sciences book series (LIFE SCIENCES)


Gibberellin (GA) metabolism in higher plants has been studied for the past 15 years with mixed success (1,2). The entire biosynthetic pathway from mevalonic acid to a C-19 GA has been conclusively demonstrated in cell-free systems from Cucurbita maxima (3). However, the pathway from mevalonic acid to GA12-aldehyde has not been convincingly demonstrated in cellular systems from higher plants. The bulk of GA metabolic work with intact higher plants has involved a study of the conversion of one GA into another. This work is almost exclusively confined to the C-19 GAs. Thus our current knowledge of GA metabolism in intact higher plants is fragmentary.
