When aleurone layers were treated with labeled gibberellin A1 ((3)H-GA1), gibberellin A5 ((3)H-GA5) and the methyl ester of (3)H-GA5 ((3)H-GA5-ME), radioactivity was accumulated by the tissue for a period of 20-30 h. After this time, radioactivity was released into the medium. Concomitantly, ribonuc

The biosynthetic steps from gibberellin A12-aldehyde (GA12-aldehyde) to C19-GAs were studied by means of a cell-free system from the embryos of immature Phaseolus vulgaris seeds. Stable-isotope-labeled GAs were used as substrates and the products were identified by gas chromatography-mass spectromet

Gibberellin A9, GA20 and GA29, all known to be endogenous to immature seeds of Pisum sativum cv. Progress No. 9, were fed in tritiated form to seeds of this cultivar cultured in vitro. [(3)H]GA9 was metabolised to [(3)H]GA20, 2ฮฒ-OH-[(3)H]GA9, H2-[(3)H]GA31 and a H2-[(3)H]GA31 conjugate. The percenta

When barley aleurone layers were incubated with (3)H-Gibberellin A1 ((3)H-GA1), the hormone was converted to (3)H-GA-X (not identified), (3)H-GA8 and two other compounds tentatively identified as (3)H-GA1-glucoside, and (3)H-GA8-glucoside. Uptake and metabolism of the (3)H-GA1 were markedly enhanced
