Short rotation coppice (SRC) is increasingly being adopted for bioenergy production, pollution remediation and land restoration. However, its long-term effects on soil microbial communities are poorly characterized. Here, we studied soil microbial functional genes and their biogeographic pattern under SRC with willow trees as compared to those under permanent grassland (C). GeoChip analysis showed a lower functional gene diversity in SRC than in C soil, whereas microbial ATP and respiration did not change. The SRC soil had lower relative abundances of microbial genes encoding for metal(-oid) resistance, antibiotic resistance and stress-related proteins. This indicates a more benign habitat under SRC for microbial communities after relieving heavy metal stress, consistent with the lower phytoavailability of some metals (i.e., As, Cd, Ni and Zn) and higher total organic carbon, NO3−-N and P concentrations. The microbial taxa–area relationship was valid in both soils, but the space turnover rate was higher under SRC within 0.125 m2, which was possibly linked to a more benign environment under SRC, whereas similar values were reached beyond thisarea. Overall, we concluded that SRC management can be considered as a phytotechnology that ameliorates the habitat for soil microorganisms, owing to TOC and nutrient enrichment on the long-term.

Abstract The extensive application of perfluoroalkyl and polyfluoroalkyl substances (PFASs) causes their frequent detection in various environments. Nevertheless, the effects of PFASs exposure on environmental microorganisms still remain unknown. In current work, two typical PFASs, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), are selected to investigate their long-term effects on soil microbes. Microbial community structure and diversity were investigated by high-throughput sequencing and multiple statistical methods. Under 90-days of exposure, PFAS treatments increased the alpha-diversity of soil microbial communities with PFOS treatment, followed by PFOA treatment. The long-term exposure of PFASs substantially changed the compositions of soil microbial communities. The most abundant phylum Proteobacteria decreased from 82.9% (without amended PFASs) to 62.1% (with PFOA treatment) and 77.8% (with PFOS treatment). As a comparison, the relative abundance of Bacteroidetes, Chloroflexi, Acidobacteria, and Ignavibacteriae increased in the PFOA or PFOS groups. Comparative co-occurrence networks were constructed to investigate the biotic interactions in the two treatments. It was found that most taxonomy nodes in the PFOA and PFOS networks were associated with the genus Hydrogenophaga and Pseudoxanthomonas, respectively. The LEfSe analysis identified a set of core taxonomies (e.g., Azospirillum, Methyloversatilis, Ancylobacter, Hydrogenophaga, and Methylomonas) in the soil microbial communities and suggested their different preferences to PFAS exposures. Functional gene prediction suggested that the microbial metabolism processes, such as nucleotide transport and metabolism, cell motility, carbohydrate transport and metabolism, energy production and conversion, and secondary metabolites biosynthesis transport and catabolism, might be significantly inhibited under PFAS exposure, which may further affect soil ecological services.

ABSTRACT Soil pH is a major factor shaping bulk soil microbial communities. However, it is unclear whether the belowground microbial habitats shaped by plants (e.g. rhizosphere and root endosphere) are also affected by soil pH. We investigated this question by comparing the microbial communities associated with plants growing in neutral and strongly alkaline soils in the Sandhills, which is the largest sand dune complex in the northern hemisphere. Bulk soil, rhizosphere and root endosphere DNA were extracted from multiple plant species and analyzed using 16S rRNA amplicon sequencing. Results showed that rhizosphere, root endosphere and bulk soil microbiomes were different in the contrasting soil pH ranges. The strongest impact of plant species on the belowground microbiomes was in alkaline soils, suggesting a greater selective effect under alkali stress. Evaluation of soil chemical components showed that in addition to soil pH, cation exchange capacity also had a strong impact on shaping bulk soil microbial communities. This study extends our knowledge regarding the importance of pH to microbial ecology showing that root endosphere and rhizosphere microbial communities were also influenced by this soil component, and highlights the important role that plants play particularly in shaping the belowground microbiomes in alkaline soils.
