Long before humans developed early warning systems, plants were already practicing a version of the same wisdom. New research from the University of Missouri reveals that when plants touch one another, they exchange chemical signals — hydrogen peroxide passing leaf to leaf — triggering thousands of stress-response genes and preparing each other for hardship. It is a quiet, molecular form of solidarity, and it may help explain why life, even in its most rooted forms, tends to fare better in community than in isolation.
