Gibberellin Production: Genetic Control in the Fungus Gibberelia fujikuroi.

The fungus Gibberella fujikuroi (Saw.) Wr. can be used in genetic studies of the production of gibberellins. A gene has been identified which controls a step in the biosynthetic pathway of gibberellin production. Apparently this step is early in the pathway for it affects the accumulation of all of the gibberellins produced by the fungus.
