How Plants Call for Help: The Immune Receptor Behind Biological Pest Control

Scientists have discovered the specific immune receptor in bean plants that detects caterpillar attacks and triggers a sophisticated defense response, attracting natural predators to eliminate the herbivores. This breakthrough reveals how plants have evolved a precise molecular sensing system over millions of years to protect themselves without relying solely on chemical defenses. Understanding this mechanism could transform agricultural practices by enabling sustainable, pesticide-free approaches to crop protection.
