Gibberellin biosynthesis and gibberellin oxidase activities in Fusarium sacchari, Fusarium konzum and Fusarium subglutinans strains

Gibberellin biosynthesis is present in Fusarium sacchari and Fusarium konzum, two species of the Gibberella fujikuroi complex, although this ability can differ significantly in different isolates. GA3 or GA1, respectively, are the main gibberellins synthesized. By contrast, Fusarium subglutinans is inactive in gibberellin biosynthesis.
