Gibberella is a genus of fungi in the family Nectriaceae.

In 1926, Japanese scientists observed that rice plants infected with Gibberella had abnormally long stems ("foolish seedling disease").[1]

A substance, gibberellin, was derived from this fungus. Gibberellin is a plant hormone that promotes cell elongation, flower formation, and seedling growth.[2]

Etymology

Pier Andrea Saccardo named the genus "Gibberella" because of the hump (Latin, gibbera) on the fungal perithecium.[3]
