“…The people have realized that soil microbes are the most sensitive organisms in the soil ecological environment and are constantly explored ways to promote soil environmental remediation by controlling soil microbes (Liu et al, 2014a). In the former study, our work indicated that Acidobacteria was the most plentiful bacterial phylum in the Sanjiang plain wetland (Sui et al, 2017). The Acidobacterial numbers are most, also accounting for 20-50%, and distributed most widely in the soil, involving in plant residue matter decomposition, ferrikinetics process, single carbon compounds metabolism and some important ecological functions on the ecological environment (Wang, 2010).…”

“…When arrived, the soils were divided into two parts: one, approximately 10 g soil was placed in a sterile microcentrifuge tube and stored in -80°C for molecular analysis; the remaining of the soils were air-dried to detect the soil physiochemical properties. These were measured as described before (Sui et al, 2017) and included the pH of the soil mixed with water (1:5 w/v); total organic carbon (TC), total nitrogen (TN) and total phosphorus (TP) content, as well as available nitrogen (AN) and available phosphorus (AP). The physiochemical properties of the soil samples from the three different land uses are summarized in Table 1.…”

“…DNA was extracted from 0.5 g of each frozen soil sample as previously described using the MOBIO PowerSoil DNA Isolation Kit (USA) (Sui et al, 2017) and stored at−20°C until use. The Acidobacterial region was selected ACIDO/342r for PCR amplification and pyrosequencing (Lee and Cho, 2011).…”

Different perturbation regimes,including disturbance caused by cultivation or the process of natural restoration can have significant effects on the soil acidobacterial community in wetland. The relationship between the community composition and diversity of acidobacteria and perturbation in wetland to quantify the extent of such disturbance related changes in northeast China. We assessed the diversity of acidobacterial communities in nine samples of wetland soil collected from pristine marsh, neighboring cropland and a restoration forest land. High-throughput sequencing of a acidobacteria-specific genomic sequence the internal transcribed spacer (16S rRNA) region was used to identify acidobacterial taxa. We obtained 1, 523, 313 sequences that represented 7881 acidobacterial operational taxonomic units across the three types of sampling sites. Of these, 2847OTUs occurred at all three site types, 814 were shared between farmland and pristine wetland, 206 were shared between forestland and pristine wetland 1459 were shared between farmland and forestland. All sites also hosted unique acidobacterial OTUs with 639 OTUs exclusive to farmland 1616 exclusive to pristine wetland and 300 exclusive to forestland. Sequences were affiliated to 25 acidobacterial subgroups throughout the dataset. Sequence abundance showed that members of Acidobacteria_Gp1, Acidobacteria_Gp3, Acidobacteria_Gp7, Acidobacteria_Gp6, Acidobacteria_Gp2, Acidobacteria_Gp4, Acidobacteria_Gp13 (relative abundance>1%), which represented an overwhelming proportion of the soil acidobacterial communities and another 18 subgroups with an average relative abundance were＜1%. The dominant subgroups that showed the greatest variation among habitat types. The soil bacterial community diversity decreased from a maximum in farmland, through the wetland, to a minimum in forestland. Canonical correlation analyses demonstrated that land use patterns changing, significantly altered the bacterial community composition of soil. The α-diversity of the soil acidobacterial community was most affected by soil physical and chemical properties, such as pH, soil organic carbon (SOC), total nitrogen (TN), available nitrogen (AN) and available phosphorus (AP). Meanwhile, the soil acidobacterial community composition was significantly affected by pH available phosphorus, nitrogen and organic carbon. Overall, the results from our study showed that the acidobacterial community composition of wetland were affected by SOC, TN, TP and AN. In addition, our results also indicate that cultivation and natural restoration influenced the acidobacterial community structure and diversity. Cultivation can significantly enhance the acidobacterial diversity; however, once the composition of the wetland bacterial community has been altered by cultivated disturbance, it might be difficult to restore to its original state. These findings highlight the importance of effectively managing the soil acidobacterial community to maintain a naturally functioning soil ecosystem.

“…The observed predominance of Basidiomycota and Ascomycota was not out of expectation due to the descriptions for these groups as general inhabitants for wetland and forest soils (Han et al., 2018; Sui, 2017). In addition, Ascomycota was more frequently identified in aquatic group than dryland group, while the Basidiomycota was more frequently identified in dryland group than aquatic group.…”

The Sanjiang Plain is the biggest freshwater wetland locating in northeastern China. Due to climate change and human activities, that wetland has degraded to a successional gradient from the original flooded wetland to dry shrub vegetation and a forest area with lower ground water level, which may result in changes in soil microbiologic structure and functions. The present study investigated the microbial diversity and community structure in relation to soil properties along that successional gradient. The soil physico‐chemical properties changed significantly with degradation stage. The Shannon diversity index of both soil bacteria (5.90–6.42) and fungi (1.7–4.19) varied significantly with successional stage (both p < .05). The community structures of soil bacteria and fungi in the early successional stages (i.e., the wetland) were significantly determined by water content, total nitrogen, and available nitrogen concentrations in soils, while those in the later successional stages (i.e., forests) were significantly structured by soil organic carbon, soil pH, and available phosphorus concentrations. These results suggest that the soil microbial structure is mainly determined by soil properties rather than by plant community such as plant species composition along successional stages.

“…Over the years, this phenomenon has gradually attracted attention, and researchers are focusing on studies describing the impact of wetland cultivation (Zhou et al, 2009), treatment of wetland pollution (Guo et al, 2014), or wetland microbial participation in carbon and nitrogen cycles Sui et al, 2017). It is now widely recognized that soil microbes are key players in the soil ecology.…”

Large-scale agricultural land reclamation activities can trigger substantial changes in the soil bacterial community by disturbances associated with growth of crops and addition of fertilizers and pesticides. In this study, the bacterial 16S gene was sequenced on the Illumina MiSeq platform for bacterial identification and taxonomy. We investigated the (i) soil bacterial diversity and community composition in natural marsh, moderate and severe intensity of interference in wetlands, and (ii)
