Evaporative cooling signals for wound healing in plants.

ABSTRACT: Repairing a damaged body part is critical for the survival of any organism. In plants, tissue damage induces rapid responses that activate defense, regeneration and wound healing. While early wound signaling mediated by phytohormones, electrical signals and reactive oxygen species is well-characterized, the mechanisms governing the final stages of wound healing remain poorly understood. Here, we show that wounding in Arabidopsis leaves induces localized cooling, likely due to evaporative water loss, accompanied by the activation of cold-responsive genes. The subsequent disappearance of localized cooling and deactivation of cold-responsive genes serve as a quantitative marker of wound healing. Based on these observations, we developed a workflow by leveraging computer vision and deep learni
