Several microorganisms possess the capacity of synthesizing gibberellins (GAs) in axenic culture. GA concentrations in the range of approximately 20 to 200 milligrams per litre of culture filtrate are produced by wild-type strains of the following fungi: Gibberella fujikuroi (GA3, GA4, GA7, GA1 and others), Sphaceloma manihoticola and other species of this genus (GA4, GA9 and others), Phaeosphaeria sp. (GA1, GA4, GA9 and others). Neurospora crassa is capable of producing GA3 in the range of…

For the triazole-type compounds and tetcyclacis, a relatively distinct correlation exists in their ability to inhibit GA formation in fungal cultures, to block ent-kaurene oxygenase in a cell-free system, and to reduce shoot growth of rice seedlings.
