某些植物根际促生细菌（PGPR）通过挥发性有机化合物（VOC）的排放在与植物没有物理接触的情况下引起诱导的系统抗性（ISR）和植物生长促进。本文综述了近年来PGPR VOCs与植物相互作用的研究进展，重点介绍了植物体内PGPR菌株释放VOCs的研究进展。特别注意的是这些细菌挥发性有机化合物引起ISR的机制。我们提供了一个概述的最新进展，在阐明PGPR VOC的相互作用的研究利用转录组，代谢组和蛋白质组分析。通过监测防御基因的表达模式，进行二维电泳，并研究防御信号无效突变体，水杨酸和乙烯已被发现是参与ISR反应的植物信号通路的关键球员。细菌挥发性有机化合物也赋予诱导的系统耐受性非生物胁迫，如干旱和重金属。还回顾了PGPR挥发性剖面的当前分析方法，并强调了未来需要的发展。为了评估PGPR VOCs对作物的潜在利用，将挥发性悬浮液施用于辣椒和黄瓜的根部，发现其在保护植物免受田间植物病原体和害虫的侵害方面是有效的。总之，这些研究提供了进一步的洞察PGPR挥发性有机化合物的生物和生态潜力，提高植物自身免疫力和/或适应现代农业中的生物和非生物胁迫。
Certain plant growth-promoting rhizobacteria (PGPR) elicit induced systemic resistance (ISR) and plant growth promotion in the absence of physical contact with plants via volatile organic compound (VOC) emissions. In this article, we review the recent progess made by research into the interactions between PGPR VOCs and plants, focusing on VOC emission by PGPR strains in plants. Particular attention is given to the mechanisms by which these bacterial VOCs elicit ISR. We provide an overview of recent progress in the elucidation of PGPR VOC interactions from studies utilizing transcriptome, metabolome, and proteome analyses. By monitoring defense gene expression patterns, performing 2-dimensional electrophoresis, and studying defense signaling null mutants, salicylic acid and ethylene have been found to be key players in plant signaling pathways involved in the ISR response. Bacterial VOCs also confer induced systemic tolerance to abiotic stresses, such as drought and heavy metals. A review of current analytical approaches for PGPR volatile profiling is also provided with needed future developments emphasized. To assess potential utilization of PGPR VOCs for crop plants, volatile suspensions have been applied to pepper and cucumber roots and found to be effective at protecting plants against plant pathogens and insect pests in the field. Taken together, these studies provide further insight into the biological and ecological potential of PGPR VOCs for enhancing plant self-immunity and/or adaptation to biotic and abiotic stresses in modern agriculture.
