    Notes: Abstract Data on the occurrence of free and conjugated gibberellins in different tribes of Gramineae are compiled and discussed with regard to their biosynthetic pathways. From the gibberellins detected so far the functioning of both the early 13-hydroxylation and the non-3,13-hydroxylation pathway of GA biosynthesis in gramineous plants can be deduced and the discovery of further gibberellin conjugates may be expected.

    Notes: Abstract. After administering [17-D2]GA20 to Phaseolus coccineus L. cv. Preisgewinner seedlings, [17-D2]GA20-O-glucoside was identified by liquid chromatography (LC)/ESI-tandem mass spectrometry (MS). Likewise, by LC/ESI-tandem MS the metabolic formation of [17-D2]GA20 glucosyl ester was established. The application of both [17-D2]-labeled GA20 13-O-glucoside and GA20 glucosyl ester to Phaseolus coccineus L. seedlings resulted in free [17-D2]GA20 by gas chromatography/MS. The results demonstrate that conjugation of GA20 and the reconversion of the glucosyl conjugates are concomitant processes in plants.
