Plants growing close together can warn one another about environmental stress, increasing their chances of survival. Experiments with thale cress showed that crowded plants activated thousands of protective genes when exposed to intense light, while isolated plants suffered severe damage. Researchers found that stressed plants released hydrogen peroxide, which passed to neighbouring plants and triggered defensive responses. This is the first evidence that this chemical can act as a warning signal between plants, allowing groups to prepare for stress collectively.
