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

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

Gibberellin A3 Is Biosynthesized from Gibberellin A20 via Gibberellin A5 in Shoots of Zea mays L.
[17- 13 C, 3 H]-Labeled gibberellin A 20 (GA 20 ), GA 5 , and GA 1 were fed to homozygous normal (+/+), heterozygous dominant dwarf ( D8 /+), and homozygous dominant dwarf ( D8/D8 ) seedlings of ZeaExpand

Internode length in Zea mays L.
Abstract[13C, 3H]Gibberellin A20 (GA20) has been fed to seedlings of normal (tall) and dwarf-5 and dwarf-1 mutants of maize (Zea mays L.). The metabolites from these feeds were identified by combinedExpand

Gibberellin Metabolism in Maize (The Stepwise Conversion of Gibberellin A12-Aldehyde to Gibberellin A20
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,Expand
