Although rice is one of the most cultivated, consumed, and essential crops worldwide, it is highly susceptible to a wide range of bacterial and fungal pathogens that significantly reduce the production and quality of rice. Recently, our research group reported that the plant growth‐promoting rhizobacterium Lysobacter gummosus OH17 was able to enhance the ethylene levels in Oryza sativa ‘Nipponbare’ plants at the late interaction stages. In this work, L. gummosus OH17 was found to be capable of inducing the overexpression of relevant genes of the jasmonic acid and ethylene transduction pathways in Nipponbare plants, such as OsACC, OsACO, OsERF3, and OsLOX, which resulted in the up‐regulation of a number of pathogenesis‐related proteins. The observed metabolic effects enhanced the disease resistance of rice against the three most devastating rice pathogens: Magnaporthe oryzae causing rice blast, Rhizoctonia solani causing rice sheath blight, and Xanthomonas oryzae pv. oryzae causing bacterial leaf blight. Furthermore, it was shown that L. gummosus OH17 also enhanced ethylene production levels in other O. sativa varieties from both the japonica and indica subspecies. Here, we report for the first time the metabolic alterations produced by plant growth‐promoting rhizobacterium L. gummosus OH17 at the late interaction stages and how these alterations induce systemic resistance.

Lysobacter gummosus OH17 在 Oryza sativa cv. 中诱导系统抗性。日本晴

尽管水稻是世界上种植、消费和必需品最多的作物之一，但它极易受到多种细菌和真菌病原体的影响，这些病原体会显着降低水稻的产量和质量。最近，我们的研究小组报告说，促进植物生长的根际细菌 Lysobacter gummosus OH17 能够在相互作用后期提高水稻 'Nipponbare' 植物中的乙烯水平。在这项工作中，发现 L. gummosus OH17 能够诱导日本晴植物中茉莉酸和乙烯转导途径相关基因的过表达，如 OsACC、OsACO、OsERF3 和 OsLOX，从而导致上调许多发病机制相关的蛋白质。观察到的代谢作用增强了水稻对三种最具破坏性的水稻病原体的抗病性：引起稻瘟病的稻瘟病菌、引起水稻纹枯病的立枯丝核菌和米黄单胞菌。引起细菌性叶枯病的稻瘟病菌。此外，研究表明 L. gummosus OH17 还提高了粳稻和籼稻亚种的其他水稻品种的乙烯产量水平。在这里，我们首次报告了植物生长促进根瘤菌 L.gumosus OH17 在相互作用后期产生的代谢改变，以及这些改变如何诱导系统抗性。树胶 OH17 还提高了粳稻和籼稻亚种的其他水稻品种的乙烯产量水平。在这里，我们首次报告了植物生长促进根瘤菌 L.gumosus OH17 在相互作用后期产生的代谢改变，以及这些改变如何诱导系统抗性。树胶 OH17 还提高了粳稻和籼稻亚种的其他水稻品种的乙烯产量水平。在这里，我们首次报告了植物生长促进根瘤菌 L.gumosus OH17 在相互作用后期产生的代谢改变，以及这些改变如何诱导系统抗性。
