Crops are negatively affected by abiotic and biotic stresses, however, plant-microbe cooperation allows prompt buffering of these environmental changes. Microorganisms exhibit an extensive metabolic capability to assist plants in reducing these burdens. Interestingly, beneficial microbes may also trigger, at the host side, a sequence of events from signal perception to metabolic responses leading to stress tolerance or protection against biotic threats. Although plants are well known for their vast chemical diversity, plant-microbial interactions often stimulate the production of a rich and different repertoire of metabolites in plants. The targeted microbial-plant interactions reprogramming plant metabolism represent potential means to foster various pest managements. However, the molecular mechanisms of microbial modulation of plant metabolic plasticity are still poorly understood. Here, we review an increasing amount of reports providing evidence for alterations to plant metabolism caused by beneficial microbial colonization. In addition, we highlight the vital importance of these metabolic reprograms for plants under stress erratic conditions. © 2019 Society of Chemical Industry.
作物受到非生物和生物胁迫的负面影响，然而，植物-微生物的合作使得植物能够迅速缓冲这些环境变化。微生物表现出广泛的代谢能力，以帮助植物减轻这些负担。有趣的是，有益微生物也可能在宿主方面触发一系列从信号感知到代谢反应的事件，从而导致对生物胁迫的耐受性或保护。尽管植物以其广泛的化学多样性而闻名，但植物-微生物的相互作用常常刺激植物产生丰富而不同的代谢物谱。靶向微生物-植物相互作用重新编程植物代谢代表了促进各种害虫管理的潜在手段。然而，微生物调节植物代谢可塑性的分子机制仍知之甚少。在这里，我们回顾了越来越多的报告，这些报告提供了有益微生物定殖导致植物代谢改变的证据。此外，我们强调了这些代谢重编程在植物应对胁迫不定条件下的重要性。 © 2019 化学工业协会。
