Diverse and abundant arbuscular mycorrhizal fungi in ecological floating beds used to treat eutrophic water

An increasing number of investigations have shown the universal existence arbuscular mycorrhizal fungi (AMF) in aquatic ecosystems. However, little is known about accurate distribution and function AMF inhabiting ecosystems, especially ecological floating beds (EFBs), which are constructed for remediation polluted water bodies. In this study, we collected root samples Canna generalis, Cyperus alternifolius, Eichhornia crassipes from three EFBs on two eutrophic lakes Wuhan, China. We aimed to investigate resources using Illumina Mi-seq technology. A total 229 operational taxonomic units (OTUs) 21 taxa 348,799 Glomeromycota sequences were detected. Glomus Acaulospora most dominant second genera EFBs, respectively. Different plant species showed varying degrees colonization (3.83–71%), diversity (6–103 OTUs, 3–15 virtual taxa), abundance (14–57,551 sequences). Low abundance, but relatively high diversity, was found C. usually considered non-mycorrhizal. This finding indicated accuracy sequencing. Our results also revealed a lognormal that observed across species. The community composition closely related nitrogen phosphorus contents. Overall, our data show harbor diverse abundant communities. Additionally, quality treated by indicating potential application plant-based bioremediation wastewater. • Aquatic plants (229 OTUs) (348,799 sequences) AMF. host different Cyperaceae, originally non-mycorrhizal, may fact be variable family. nutrient concentrations (nitrogen phosphorus).
