“…The relationships between sediment parameters and microbial communities were analyzed by Mantel tests and redundancy analysis (RDA). Variation partition analysis (VPA) was used to quantify the relative contributions of the physicochemical factors to bacterial and archaeal communities with the vegan package (Yu et al, 2021b). Differences among sites were evaluated by one-way analysis of variance (ANOVA) in SPSS 18.0 software.…”

“…Environmental factors have significant effects on driving microbial community assembly (Rath and Rousk, 2015;Jiao and Lu, 2020a;Yu et al, 2021b). Previous studies indicated that pH could influence the diversity and structure of microbial communities at local (Tripathi et al, 2014;Yu et al, 2020;Zhong et al, 2020), regional (Griffiths et al, 2011;Tripathi et al, 2012;Jiao et al, 2019) and global scales (Fierer and Jackson, 2006).…”

Understanding the microbial community assembly is an essential topic in microbial ecology. Coastal wetlands are an important blue carbon sink, where microbes play a key role in biogeochemical cycling of nutrients and energy transformation. However, the drivers controlling the distribution patterns and assembly of bacterial and archaeal communities in coastal wetland are unclear. Here we examined the diversity, co-occurrence network, assembly processes and environmental drivers of bacterial and archaeal communities from inshore to offshore sediments by the sequencing of 16S rRNA gene amplicons. The value of α- and β-diversity of bacterial and archaeal communities generally did not change significantly (P > 0.05) between offshore sites, but changed significantly (P < 0.05) among inshore sites. Sediment pH and salinity showed significant effects on the diversity and keystone taxa of bacterial and archaeal communities. The bacterial and archaeal co-occurrence networks were inextricably linked with pH and salinity to formed the large network nodes, suggesting that they were the key factors to drive the prokaryotic community. We also identified that heterogeneous and homogeneous selection drove the bacterial and archaeal community assembly, while the two selections became weaker from offshore sites to inshore sites, suggesting that deterministic processes were more important in offshore sites. Overall, these results suggested that the environmental filtering of pH and salinity jointly governed the assembly of prokaryotic community in offshore sediments. This study advances our understanding of microbial community assembly in coastal wetland ecosystems.

“…In this study, archaeal abundance showed a positive correlation with soil basal respiration, which was a major process that controlled the C loss from terrestrial ecosystem. This result suggested that archaea, instead of bacteria and fungi may play crucial roles in soil C mineralization in urban forests in Shanghai, China (Wang et al., 2020; Yu et al., 2021).…”

“…Meanwhile, Cu content showed a negative association with the number of OTUs, Shannon index and Chao index in both endosphere and rhizosphere communities ( Table S3 ). Generally, microbial diversity decreases as the contamination gradient increases, because an increase in toxic metal(loids) concentration generally means more harshness [ 53 , 54 ]. Similar to previous studies, the bacterial diversity and richness were found to be lowest in the samples collected from the heavily Cu contaminated site (DY) ( Figure 1 ), indicating that a high level of Cu contamination could suppress or result in the death of sensitive soil microbes, and, therefore, subsequently affect the formation of the soil microbial community [ 55 ].…”

Metallophytes microbiota play a key role in plant growth and resistance to heavy metal stress. Comparing to the well-studied single or some specific plant growth-promoting (PGP) bacterial strains, our current understanding of the structural and functional variations of microbiome of metallophytes is still limited. Here, we systematically investigated the endophytic and rhizosphere bacterial community profiles of a metallophyte Commelina communis growing in different Cu-polluted soils by high-throughput sequencing technology. The results showed that the rhizosphere communities of C. communis exhibited a much higher level of diversity and richness than the endosphere communities. Meanwhile, shifts in the bacterial community composition were observed between the rhizosphere and endosphere of C. communis, indicating plant compartment was a strong driver for the divergence between rhizosphere and endosphere community. Among the environmental factors, soil Cu content, followed by OM, TP and TN, played major roles in shaping the bacterial community structure of C. communis. At the highly Cu-contaminated site, Pseudomonas and Sphingomonas were the predominant genera in the endophytic and rhizospheric bacterial communities, respectively, which might enhance copper tolerance as PGP bacteria. In summary, our findings will be useful to better understand metallophyte–microbe interactions and select suitable bacterial taxa when facilitating phytoremediation.
