Oxygen and Ethylene Diffusion Triggers Wound Healing in Plants, Researchers Discover

Oxygen and ethylene diffusion triggers wound healing in plants, researchers discover

Scientists at the University of Helsinki discovered how plants heal their protective outer layer, the periderm. The diffusion of ethylene and oxygen through a wound triggers repair—a finding with potential implications for crop resilience and food preservation.

Injured plants use gaseous cues to initiate repair of their outer layers

The periderm layers of plants form an outer protective barrier. If the periderm is broken, movement of the gases ethylene and oxygen triggers a healing process.

Plants Detect Barrier Integrity Through Gas Diffusion

In a groundbreaking study that sheds new light on how plants maintain and restore their essential protective barriers, researchers have uncovered a sophisticated mechanism by which vascular plants monitor the integrity of their outer layers using gaseous signals. The latest work reveals that plants, specifically Arabidopsis thaliana, detect breaches in their barrier tissues by sensing […]
