Silver nanoparticles (AgNPs) have been widely used in various fields due to their antimicrobial activities. However, the antimicrobial mechanisms of AgNPs against fungi, especially on transcriptional level, are still unclear. In this study, the inhibitory property of AgNPs against Fusarium solani species complex was investigated. Transmission electron microscopes were used to observe the alterations in morphology and cellular structure of fungal hyphae treated with AgNPs. Disturbances in the cell walls and membranes, as well as empty space in the cytoplasm were observed. The transcriptome sequencing of F. solani species complex mycelia was performed using the Illumina NextSeq 500 ribonucleic acid sequencing (RNA-Seq) platform. In the RNA-Seq study, AgNPs treatment resulted in 2503 differentially expressed genes (DEGs). Gene Ontology (GO) analysis revealed that the DEGs were mainly involved in 6 different terms. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis also revealed that energy and substance metabolism, signal transduction and genetic information processing were the most highly enriched pathways for these DEGs. In addition, RNA-seq results were validated by quantitative polymerase chain reactions (qPCRs). Our findings enhanced the understanding of the antifungal activities of AgNPs and the underlying molecular mechanisms, and provided a new perspective for investigating this novel antifungal agent.

转录组测序分析揭示了土壤真菌枯萎病菌复合物的银纳米颗粒抗真菌分子机制。

银纳米颗粒(AgNPs)由于其抗菌活性而已广泛用于各个领域。但是,AgNPs对真菌的抗菌机制,特别是在转录水平上,尚不清楚。在这项研究中,研究了AgNPs对茄枯萎菌种复合物的抑制作用。用透射电子显微镜观察了用AgNPs处理的真菌菌丝的形态和细胞结构的变化。观察到细胞壁和细胞膜的紊乱,以及细胞质中的空白。使用Illumina NextSeq 500核糖核酸测序(RNA-Seq)平台对茄茄种菌丝体菌丝体进行转录组测序。在RNA-Seq研究中,AgNPs处理导致2503个差异表达基因(DEG)。基因本体论(GO)分析显示,DEG主要涉及6个不同的术语。京都基因与基因组百科全书(KEGG)分析还显示,能量和物质代谢,信号转导和遗传信息处理是这些DEG的最丰富的途径。此外,RNA-seq结果通过定量聚合酶链反应(qPCR)进行了验证。我们的发现加深了对AgNPs的抗真菌活性及其潜在分子机制的了解,并为研究这种新型抗真菌剂提供了新的视角。信号转导和遗传信息处理是这些DEG最丰富的途径。此外,RNA-seq结果通过定量聚合酶链反应(qPCR)进行了验证。我们的发现加深了对AgNPs的抗真菌活性及其潜在分子机制的了解,并为研究这种新型抗真菌剂提供了新的视角。信号转导和遗传信息处理是这些DEG最丰富的途径。另外,RNA-seq结果通过定量聚合酶链反应(qPCR)进行了验证。我们的发现加深了对AgNPs的抗真菌活性及其潜在分子机制的了解,并为研究这种新型抗真菌剂提供了新的视角。
