Which fungus causes the disease known as foolish seeding?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Disease**: The disease known as "foolish seedling" primarily affects rice plants. It causes seeds to germinate prematurely while still attached to the mother plant.

2. **Identifying the Causative Agent**: The fungus responsible for this disease is identified as *Gibberella fujikuroi*. This fungus is known to produce gibberellins, which are plant hormones that promote growth.

3. **Mechanism of Action**: The gibberellins produced by *Gibberella fujikuroi* induce the activity of enzymes that hydrolyze stored food in the seeds. This process provides energy for cell respiration, leading to the breaking of dormancy in the seeds.
