Plant root injuries unleash pressure waves that travel long distances
When plant roots are injured—by insects, for example—the pressure inside the root drops, and a pressure wave spreads rapidly throughout the root system. In neighboring roots, tiny proteins that act as mechanical pressure sensors detect the change and generate electrical and calcium signals.
Plant Signaling Mechanisms
-
Root Injury Response: Insect-induced root injury causes an immediate internal pressure drop.
-
Pressure Waves: Injury creates pressure waves that travel rapidly across root systems.
-
Mechanical Sensors: Tiny proteins act as sensors to detect root pressure changes.
-
Signal Generation: Sensors translate pressure drops into electrical and calcium signals.
