Volatile organic compounds (VOCs) are crucial plant responses to biotic and abiotic stimuli, emitting signals that convey the physiological state of the plant. Research on plant-plant interactions primarily focuses on defensive reactions in recipient plants, but VOCs also influence hormone communication and metabolism, affecting overall plant fitness. This summary highlights how VOC exposure impacts receiving plants, detailing key chemical cues, VOC absorption, conversion, and surface adsorption. Significant changes in growth, reproduction, and metabolism are discussed, emphasizing the need for further research on whole plant responses to fully understand VOC effects.
