摘要
植物源挥发性有机物(BVOCs)是植物的次生代谢产物,具有防御和信号等多种生态功能。对植物BVOCs的研究正成为环境和生态学的热点前沿。氮沉降作为植物的养分和环境胁迫双重因子,亦改变植物防御相关BVOCs(dBVOCs)的排放,影响物种间信息交流以及生存发展,乃至整个生态系统的结构和功能,然而,相关研究十分缺乏。该文聚焦萜类、绿叶挥发物和水杨酸甲酯这3类dBVOCs,阐述它们的主要成分、合成途径、生态功能以及对各种生物和非生物胁迫因素的响应情况;重点论述了氮沉降对这些dBVOCs的影响,并讨论氮磷限制情况下它们的响应趋势及相关机理。今后,亟需深入并拓展dBVOCs的相关研究及机理探讨,攻破dBVOCs在研究方法和检测设备上的难题,并加强不同学科领域的交叉研究,为全球变化背景下树木的种植管理和虫害的绿色防治提供理论支持,助力可持续发展。
Biogenic volatile organic compounds(BVOCs)are secondary metabolites of plants that play various ecological roles,such as defense and signaling.They have become a popular topic in environmental and ecological studies.Nitrogen deposition is a dual factor of nutrient and environmental stress for plants that alters the emission of plant defense-related BVOCs(dBVOCs).It affects inter-species communication,their survival and development,and structure and function of the entire ecosystem.However,relevant research is limited.In this study,we focused on three types of dBVOCs,namely,terpenes,green leaf volatiles,and methyl salicylate,and elucidated their main components,synthesis pathways,ecological functions,and responses to various biotic and abiotic stressors.We further examined the impact of nitrogen deposition on these dBVOCs,exploring their response trends and related mechanisms under nitrogen-phosphorus limitation.Future research is necessary to deepen and expand the understanding of dBVOCs by uncovering their underlying mechanisms.Additionally,efforts should be made to overcome the challenges in research methods and detection devices for dBVOCs and strengthen interdisciplinary collaboration.Such advancements can provide theoretical support for tree planting management,green pest prevention and control,and promotion of sustainable development in the context of global changes.
