Gibberellins A 19 and A 24 from Yams, Dioscorea bulbifera, D. pentaphylla and D. oppositifolia

Gibberellin A 19 (GA 19 ) and GA 24 were identified by gas chromatography-mass spectrometry from growing shoots of four strains of three species of D ioscorea, D. bulbifera var. vera, D. pentaphylla and D. oppositifolia (yams), which are distributed in the subtropical and tropical regions of Asia.

Summary:Gibberellin A 19 (GA 19 ) and GA 24 were identified by gas chromatography-mass spectrometry from growing shoots of four strains of three species of D ioscorea, D. bulbifera var. vera, D. pentaphylla and D. oppositifolia (yams), which are distributed in the subtropical and tropical regions of Asia. An earlier report indicated the presence of several GAs including GA 19 and GA 24 in a cultivated temperate species of East Asia, D. opposita; these findings suggest possible coexistence of two GA biosynthetic pathways, early 13-hydroxylation and non-13-hydroxylation pathways comm only in Asian species of Dioscorea
