Studies on the biosynthesis of gibberellins from (−)-kaurenoic acid in cultures of Gibberella Fujikuroi
Abstract Gibberella fujikuroi utilizes (−)-kaur-16-en-19-oic acid as a precursor for the synthesis of gibberellins. A study of the time-course of the conversion of kaurenoic acid into gibberellinsExpand

The dwarf-1 (dt) Mutant of Zea mays blocks three steps in the gibberellin-biosynthetic pathway.
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 whichExpand

Qualitative and Quantitative Analyses of Gibberellins in Vegetative Shoots of Normal, dwarf-1, dwarf-2, dwarf-3, and dwarf-5 Seedlings of Zea mays L.
Gibberellins A(12) (GA(12)), GA(53), GA(44), GA(19), GA(17), GA(20), GA(29), GA(1), and GA(8) have been identified from extracts of vegetative shoots of normal (wild type) maize using full scanExpand

Position of the metabolic block for gibberellin biosynthesis in mutant b1-41a of Gibberella fujikuroi
Abstract Mutant B1-41a, obtained by UV-irradiation of Gibberella fujikuroi strain GF-1a, does not metabolise mevalonic acid lactone (MVL), ent -kaur-16-ene, ent -kaurenol, and ent -kaurenal toExpand

Hydrolysis and reconjugation of gibberellin A20 glucosyl ester by seedlings of Zea mays L.
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 extractedExpand

Comparison of ent-kaurene and ent-isokaurene synthesis in cell-free systems from etiolated shoots of normal and dwarf-5 maize seedlings
An active cell-free system, prepared from young etiolated shoots of normal Zea mays seedlings, was shown to biosynthesize the terpenoid hydrocarbons ent-kaur-16-ene, squalene and phytoene fromExpand

The Metabolism of Gibberellin A20 to Gibberellin A1 by Tall and Dwarf Mutants of Oryza sativa and Arabidopsis thaliana
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.Expand
