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 کاملThe NADPH-cytochrome P450 reductase gene from Gibberella fujikuroi is essential for gibberellin biosynthesis.
The fungus Gibberella fujikuroi is used for the commercial production of gibberellins (GAs), which it produces in very large quantities. Four of the seven GA biosynthetic genes in this species encode cytochrome P450 monooxygenases, which function in association with NADPH-cytochrome P450 reductases (CPRs) that mediate the transfer of electrons from NADPH to the P450 monooxygenases. Only one cpr...
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...
متن کاملThe P450-1 gene of Gibberella fujikuroi encodes a multifunctional enzyme in gibberellin biosynthesis.
Recent studies have shown that the genes of the gibberellin (GA) biosynthesis pathway in the fungus Gibberella fujikuroi are organized in a cluster of at least seven genes. P450-1 is one of four cytochrome P450 monooxygenase genes in this cluster. Disruption of the P450-1 gene in the GA-producing wild-type strain IMI 58289 led to total loss of GA production. Analysis of the P450-1-disrupted mut...
متن کاملThe gibberellin 20-oxidase of Gibberella fujikuroi is a multifunctional monooxygenase.
The genes for gibberellin (GA) biosynthesis are clustered in the fungus Gibberella fujikuroi. In addition to genes encoding a GA-specific geranylgeranyl diphosphate synthase and a bifunctional ent-copalyl diphosphate/ent-kaurene synthase, the cluster contains four cytochrome P450 monooxygenase genes (P450-1, -2, -3, -4). Recently it was shown that P450-4 and P450-1 encode multifunctional enzyme...
