The hydraulic signal was about 10,000 times faster than previously described calcium waves used for comparison. GLR3.3\/3.6 receptors then amplified depolarization and stress-hormone responses followed.<\/p>\n

Unlike some leaf alarms, the root signal weakened exponentially with distance, which may suit the slower movement of pests through soil.<\/p>\n

How pressure becomes information<\/h2>\n

Plant cells maintain high turgor. Damage causes a sudden pressure drop that travels physically through vascular tissue; mechanosensitive MCA1 ion channels translate it into membrane-voltage and calcium changes.<\/p>\n

How causality was tested<\/h2>\n

The team combined voltage recording, calcium imaging and genetic comparisons. Optogenetics also produced repeated calcium signals without wounding to test later responsiveness.<\/p>\n

Repeated signals reduced sensitivity<\/h2>\n

Preconditioned roots showed weaker electrical responses to later glutamate or injury. This is short-term sensitivity adjustment, not proof of memory or complete immunity.<\/p>\n

Distance to farm use<\/h2>\n

Crops differ in roots, pests and soils. Crop-specific physiology and long field studies must show whether the pathway can protect yield or reduce pesticide use.<\/p>\n

In Arabidopsis experiments, a pressure drop crossed the root network at about 75 mm\/s, and MCA1 channels in neighboring roots converted it into electrical and calcium signals.
