[ 14 C 4 ]GA 53 , [ 14 C 4 ]GA 44 , and [ 2 H 2 / 14 C 4 ]GA 19 were injected separately into seedlings of rice ( Oryza sativa) using a dwarf mutant ( d 35 ) that has low levels of endogenous gibberellins (GAs). After 8 h incubation, the shoots were

This paper reports the identification of gibberellin A 1 (GA 1 ), GA 17 , GA 19 , GA 20 , GA 29 , and GA 53 from extracts of normal (wild-type) maize callus using full-scan GC-Mass Spectrometry and Kovats retention indices (KRIs). In addition, eviden

Whether 3-epigibberellin(3-epiGA1) is endogenous in plants or is formed from GA1 as an artefact, can be determined by adding [13C]GA1 to the plant material as an internal reference and measuring the 12C:13C ratio of 3-epiGA1 and GA1, recovered from t

The purpose of this study was to demonstrate the metabolism of gibberellin A20 (GA20) to gibberellin A1 (GA1) by tall and mutant shoots of rice (Oryza sativa L.) and Arabidopsis thaliana (L.) Heynh. The data show that the tall and dx mutant of rice a

The [6-2H]glucosyl ester of [17-13C,3H]gibberellin A20 (GA20) was injected into light-grown 14-day-old seedlings of normal, dwarf-1, and dwarf-5 maize (Zea mays L.). The plant material was extracted 24 h later, and the extracts were purified by solve

Young shoots of normal maize (Zea mays L.) were used to determine both the stepwise metabolism of ent-kaurene to gibberellin A(12)-aldehyde and the endogenous presence of the members in this series. Each of the five steps in the sequence was establis

Combined gas chromatography-mass spectrometry (GCMS) was used to identify and quantify specific cytokinins from Porphyra perforate J. Ag. and Sargassum muticum (Yendo) Fensh. The level of isopentenyladenosine was estimated to be 0.6 μ·kg−1 fresh

In plants, gibberellin (GA)-responding mutants have been used as tools to identify the genes that control specific steps in the GA-biosynthetic pathway. They have also been used to determine which native GAs are active per se, i.e., further metabolis

The stepwise metabolism of gibberellin A12-aldehyde (GA12-aldehyde) to GA20 is demonstrated from seedling shoots of maize (Zea mays L.). The labeled substrates [13C,3H]GA12-aldehyde, [13C,3H]GA12, [14C4]GA53, [14C4/2H2]GA44, and [14C4/2H2]GA19 were f
