The plant hormone gibberellin was isolated from a fungus causing "foolish-seedling disease" in rice plants. This fungus was found to produce a substance (gibberellin) that causes excessive elongation of the stem, resulting in the plants growing tall, spindly, and pale, with little root or seed development. Gibberellins are now known to play a role in stem elongation, germination, and other developmental processes in plants.
