Gibberellins

Gibberellins. History of discovery from a plant disease phenomenon. Prior to world war II Japanese scientists were investigating a rice disease that made plants grow very tall but prevented grain formation. They showed that a chemical secreted by the disease fungus caused the hyper-elongation.
