Regulation of Gibberellin Biosynthesis in Gibberella fujikuroi.
Gibberellin production by Gibberella fujikuroi started only after the nitrogen source was depleted and ceased upon its renewal. Nitrogen repression of gibberellin biosynthesis is not an indirect effect of the growth arrest that follows the depletion of an essential nutrient because gibberellins were not produced upon depletion of phosphate. Mycelia produced gibberellins when suspended in a gluc...
متن کاملGibberellin 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, [14C4]GA53, [14C4/2H2]GA44, and [14C4/2H2]GA19 were fed individually to dwarf-5 vegetative shoots. Both [13C,3H]GA12-aldehyde and [13C,3H]GA12 were also added individually to normal shoots. The labele...
متن کاملGibberellin receptor and its role in gibberellin signaling in plants.
Gibberellins (GAs) are a large family of tetracyclic, diterpenoid plant hormones that induce a wide range of plant growth responses. It has been postulated that plants have two types of GA receptors, including soluble and membrane-bound forms. Recently, it was determined that the rice GIBBERELLIN INSENSITIVE DWARF1 (GID1) gene encodes an unknown protein with similarity to the hormone-sensitive ...
متن کاملGibberellin metabolism and signaling.
Gibberellins (GAs) are a family of plant hormones controlling many aspects of plant growth and development including stem elongation, germination, and the transition from vegetative growth to flowering. Cloning of the genes encoding GA biosynthetic and inactivating enzymes has led to numerous insights into the developmental regulation of GA hormone accumulation that is subject to both positive ...
متن کاملInhibition of Gibberellin Production in the Fungi Gibberella fujikuroi and Sphaceloma manihoticola by Plant Growth Retardants.
The effect of different types of plant growth retardants on fungal gibberellin (GA) formation has been studied in cultures of Gibberella fujikuroi and Sphaceloma manihoticola. Quaternary ammonium compounds (chlormequat chloride, mepiquat chloride, Amo-1618), triazoles (uniconazole and several experimental compounds), and the norbornanodiazetine tetcyclacis inhibited GA biosynthesis in both fung...
