Fungal infections significantly alter the emissions of volatile organic compounds (VOCs) by plants, but mechanisms for VOCs affecting fungal plants remain largely unknown. Here, we found that infection Botrytis cinerea upregulated linalool production strawberries and fumigation with was able to inhibit fruits fungus. Linalool treatment downregulated expression rate-limiting enzymes in ergosterol biosynthesis pathway, this reduced content fungi cell membrane impaired integrity. also caused damage mitochondrial membranes collapsing potential genes involved adenosine triphosphate (ATP) production, resulting a significant decrease ATP content. increased levels reactive oxygen species (ROS), response which treated cells produced more ROS scavenger pyruvate. RNA-Seq proteomic analysis data showed slowed rates transcription translation.
