    • ‘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.’
    • ‘Finally, decapitated roots don't seem to show hydrotropism, which hints at the root caps playing a major role in this phenomena.’
    • ‘Sensor cells for the presence of water are found in the root cap and studies indicated that calcium plays a role in the induction of root hydrotropism.’
