Analysis of Volatile Organic Compounds and Comparison of Heat Resistance Related Gene Expression in <i>Pleurotus ostreatus</i> Under Heat Stress.

ABSTRACT: Heat stress induces oxidative stress in Pleurotus ostreatus (P. ostreatus), inhibiting the growth of both mycelium and fruiting bodies. While various studies have analyzed the physiological responses of P. ostreatus under heat stress conditions, comprehensive research comparing physiological responses in mycelium and fruiting bodies through metabolomic analysis of volatile organic compounds has not been conducted. In this study, we invested the levels of volatile organic compounds (VOCs), the activity of VOC synthesis-related enzymes, and the expression of heat resistance-related genes in mycelium and fruiting bodies exposed to heat stress. The total VOC levels measured in mycelium increased, whereas those in fruiting bodies decreased, indicating contrasting responses.
