Plants emit a diverse array of phytogenic volatile organic compounds (VOCs). The production and emission of VOCs has been an important area of research for decades. However, recent research has revealed the importance of VOC catabolism by plants and VOC degradation in the atmosphere for plant growth and survival. Specifically, VOC catabolism and degradation have implications for plant C balance, tolerance to environmental stress, plant signaling, and plant-atmosphere interactions. Here we review recent advances in our understanding of VOC catabolism and degradation, propose experiments for investigating VOC catabolism, and suggest ways to incorporate catabolism into VOC emission models. Improving our knowledge of VOC catabolism and degradation is crucial for understanding plant metabolism and predicting plant survival in polluted environments.
植物会释放出多种多样的植物源挥发性有机化合物（VOCs）。几十年来，植物 VOCs 的产生和排放一直是研究的重点领域。然而，最近的研究揭示了植物 VOC 分解代谢以及大气中 VOC 降解对于植物生长和生存的重要性。具体而言，VOC 分解代谢和降解会影响植物的碳平衡、对环境胁迫的耐受能力、植物信号转导以及植物-大气相互作用。本文综述了近年来人们对于 VOC 分解代谢和降解的理解进展，提出了用于研究 VOC 分解代谢的实验建议，并就如何将分解代谢纳入 VOC 排放模型提出了看法。深入了解 VOC 分解代谢和降解对于理解植物代谢以及预测污染环境中植物的生存能力至关重要。
