The gibberellins produced by the fungus caused normal healthy rice plants to become unusually tall.

Dwarf pea plants have a mutation in the gibberellin biosynthesis pathway.

If gibberellin is applied to the stems of dwarf pea plants, the stems elongated so that the plant reach normal health.

Pea plants carrying the dwarf mutation would be expected to have higher levels of gibberellin in their stems than normal plants.
