青枯雷尔氏菌（Ralstonia Solanacearum）是引起番茄青枯病的土传植物病原菌之一。纳米技术是一个新兴的研究领域，特别是纳米颗粒（NPs）作为纳米农药管理植物病害的应用越来越受到关注。然而，NP和根际细菌群落之间的相互作用在很大程度上仍然难以捉摸。研究表明，纳米金属颗粒（CuO、ZnO和FeO）不同程度地降低了青枯病的发病率，并影响了根际细菌群落的组成和结构。结果表明，施用金属氧化物纳米颗粒可以改善TBW感染的番茄植株的形态和生理参数。其中，CuONPs的修正显着增加Chao1和Shannon指数。在早期阶段（第二周），它显着减少了病原体的相对丰度。但有益链霉菌的相对丰度明显增加，与致病菌的相对丰度呈负相关。此外，纳米处理组将富集一些潜在的有益细菌，如鞘氨醇单胞菌科，根瘤菌科等物种。总的来说，我们的研究提供了证据和策略，防治土传病害番茄青枯病与金属氧化物纳米粒子。
Ralstonia Solanacearum is one of the most infectious soil-borne bacterial plant pathogens, causing tomato bacterial wilt (TBW). Nanotechnology is an emerging area of research, particularly the application of nanoparticles (NPs) as nanopesticides to manage plant disease is gaining attention nowadays. However, the interaction between NPs and rhizosphere bacterial communities remains largely elusive. This study indicated that metal NPs (CuO, ZnO, and FeO) reduced the incidence of bacterial wilt to varying degrees and affected the composition and structure of the rhizosphere bacterial community. The results revealed that the application of metal oxide NPs can improve the morphological and physiological parameters of TBW infected tomato plants. Among all, CuONPs amendments significantly increase the Chao1 and Shannon index. In the early stage (the second week), it significantly reduces the relative abundance of pathogens. However, the relative abundance of beneficial Streptomyces bacteria increased significantly, negatively correlated with the relative abundance of pathogenic bacteria. In addition, the nano-treatment group will enrich some potential beneficial bacteria such as species from Sphingomonadaceae, Rhizobiaceae, etc. In general, our research provides evidence and strategies for preventing and controlling soil-borne disease tomato bacterial wilt with metal oxide NPs.
