Biochemical genetic studies on the production of gibberellins by the fungus Gibberella fujikuroi have identified two genes which control different steps in the biosynthetic pathway. One gene ( g 1 ) controls the production of all of the gibberellins: the second gene ( g 2 ) controls the production of GA 1 and GA 3 only. Ascospores are not ordered in the ascus of this fungus. This apparent spore slippage precludes mapping of these genes to their respective centromeres.
