- Such seedlings behaved identically to seedlings grown on uncovered filter paper and, hence, any possible effects of hydrotropism were eliminated.
- Our experiment proved that hydrotropism really does exist, and watering the plants differently affects root growth.
- These analyses indicate that the application of new genetic screens for dissecting complex signaling phenomena such as hydrotropism is promising.
