How Plants Talk to Themselves Under Stress: New Visualization
A new imaging breakthrough reveals how plants send distress signals between leaves, stems, and roots in real time. It rewrites plant biology.
Key Takeaways
- A novel fluorescent biosensor produces the first real-time, whole-plant visualization of stress signaling in action
- Calcium waves and reactive oxygen species cascade through plant vascular systems within seconds of damage events
- The internal communication network bears striking resemblance to animal nervous systems in speed and coordination
