Here's why:
* Crazy-seedling disease: This disease is caused by the fungus Gibberella fujikuroi.
* Gibberellins: These are a group of plant hormones that play a crucial role in stem elongation, seed germination, and fruit development.
* Discovery: In the early 20th century, Japanese scientists observed rice plants affected by bakanae disease (another name for crazy-seedling disease). They discovered that the fungus producing this disease secreted a substance that caused the rice plants to grow abnormally tall and thin. This substance was later identified as gibberellin.
So, the fungus Gibberella fujikuroi, causing crazy-seedling disease, produces the plant hormone gibberellin, leading to the characteristic abnormal growth in affected plants.
