Effects of silver nanoparticles on fluvo-aquic soil fungal community structure and diversity in maize rhizosphere
Rhizosphere fungi play an important role in soil ecosystems.In this study,a pot experiment was established to investigate the responses of fluvo-aquic soil fungal assemblages in maize rhizosphere to different application level of silver nanoparticles (AgNPs) (0.025,0.25,2.Smg/kg) using Illumina sequencing analysis method.The sequencing data revealed that fluvo-aquic soil fungal community in maize rhizosphere was dominated by Ascomycota,followed by Basidiomycota,Blastodimycota,Chytridiomycota,Glomermycota and Zygomycota.AgNPs at 2.5mg/kg greatly shifted the AM fungal community composition,showing as decreased proportion of Rhizopus,Fusarium and Mortierella.It was found that the values of soil dissolved organic carbon (DOC) contents were significantly decreased (P<0.05) under the high (2.Smg/kg) application level of AgNPs.Statistical analysis revealed that changes in fungal community composition and diversity were strongly (P<0.05) correlated with changes in soil DOC contents induced by AgNPs.
