“…Hence, homogenous dispersal dominated in the leaf and stem endosphere. Some studies have demonstrated that deterministic processes dominate the assemblage of microbial communities in the soil of bulk and rhizosphere (Fan et al ., 2017; Zhang et al ., 2018b). While, dissimilar results emerged in our study showing that variation in selection occurred in the bulk soil, but the stochastic processes still dominated in the compartments.…”

“…Plant tissues provide unique ecological habitats for the diverse microorganisms that live in them, and the plant‐associated microbiome and complex plant‐microbe interactions play an essential role in plant performance and resistance to abiotic stress (Ikeda et al ., 2010; Bulgarelli et al ., 2013). Some studies have investigated the biogeographic patterns and their assembly processes of soil‐root‐associated microbial communities (Zhang et al ., 2018a; Zhang et al ., 2018b). There are also studies that have briefly examined the biogeographic distribution of the plant microbiome in Agave species (Coleman‐Derr et al ., 2016) and in Cycas panzhihuaensis (Zheng and Gong, 2019), but the assembly processes of the plant shoot‐associated endosphere (stem and leaf) remain unknown.…”

Although studies of biogeography in soil bacterial communities have attracted considerable attention, the generality of these patterns along with assembly processes and underlying drivers is poorly understood in the inner tissues of plants. Plant tissues provide unique ecological habitats for microorganisms, which play an essential role in plant performance. Here, we compared core bacterial communities among five soil–plant associated compartments of common bean across five sampling sites in China. Neutral and null modelling consistently suggested that stochastic processes dominated the core community assembly processes and escalated from the belowground compartments to the inner tissues of aerial plant parts. The multiple distance‐decay relationships also varied and had flattened patterns in the stem endosphere, which were shaped by distinct environmental factors in each compartment. Coexistence patterns also varied in topological features, in addition with the sparsest networks in the stem endosphere resulted from the interaction with the stochastic processes. This study considerably expanded our understanding of various biogeographic patterns, assembly processes, and the underlying mechanisms of core bacterial communities between aerial and belowground compartments of common bean. That will provide a scientific basis for the reasonable regulation of core bacterial consortia to get better plant performance.

“…Many studies have shown that the microbial community in the rhizosphere is distinct from that in bulk soil because the root exudates and deposits in the rhizosphere change the micronutritional environment (Edwards et al, 2015;Peiffer et al, 2013;Zhang et al, 2017;Zhang et al, 2018aZhang et al, , 2018b. In addition, CR has frequently been demonstrated to be a major factor affecting the shifts in microbial community in both bulk and rhizospheric soils (Meriles et al, 2009;O'Donnell, Seasman, Macrae, Waite, & Davies, 2001).…”

“…Generally, fungal species have a wider range of optimal growth pH values than bacteria (Nevarez et al, 2009;Wheeler et al, 1991). Thus, soil nutrition rather than soil pH is frequently observed to be the master regulator of fungal community composition (Lauber, Strickland, Bradford, & Fierer, 2008;Liu et al, 2015;Yang et al, 2017), but exceptions to this trend have been reported (Zhang et al, 2018b). In this study, we found that the soil C/N ratio was a major factor affecting the fungal diversity and composition of bulk soil (Table 1; Table S5); this finding is different from that of our previous investigation of the biogeographic distribution of fungal communities across the black soil zone, which showed that the total soil carbon content was the major determinant (Liu et al, 2015).…”

Continuous cropping of soybean causes soil degradation and decreased soybean yield in Northeast PR China. However, the mechanism underlying the effect on soil fungal communities and the relationship between these effects and cropping systems have not yet been fully elucidated. In this study, we comparatively investigated the abundance, diversity, and structures of fungal communities in the bulk and rhizospheric soils of soybean grown in two cropping systems, that is, continuous cropping (CC) of soybean and cropping rotation (CR) with maize using real‐time Polymerase Chain Reaction (PCR) and Illumina MiSeq sequencing methods. The results showed that the rhizospheric soil fungal abundance was significantly higher in CC than in CR, but the opposite trend was observed in bulk soils. CC decreased the fungal alpha diversity in both bulk and rhizospheric soils compared with CR. The fungal community compositions were distinctly different between CC and CR in both bulk and rhizospheric soils, and the composition and diversity in bulk soils were predominantly affected by the soil carbon to nitrigen (C/N) ratio. The soil fungal functional groups varied between the two cropping systems; CC increased the relative abundances of the potentially pathogenic fungi Fusarium oxysporum and Lectera longa and beneficial fungi Mortierella sp. and Paecilomyces lilacinus. In contrast, CR increased the relative abundance of Ustilago maydis, which is a pathogen that causes corn smut. Our findings showed that CC increased the abundances of plant pathogens, which is harmful to soybean growth; in contrast, the abundances of some beneficial fungi also increased, which suggested that suppressive soils might be developed after long‐term CC.

“…Developed and developing countries are both increasingly focusing on the application of GM technology in agriculture, including China. After 20 years of development, China has achieved advances in the field of biotechnology research and devel-opment (Zhang et al, 2018;Feng and Yang, 2019). While GM crops bring significant benefits to humans, biosafety issues, including environmental and biological factors, need to be considered (Benbrook, 2016;ISAAA, 2017;.…”

Impact of a <i>G2-EPSPS</i> & <i>GAT</i> Dual Transgenic Glyphosate-Resistant Soybean Line on the Soil Microbial Community under Field Conditions Affected by Glyphosate Application

In the past thirty years, the biosafety of the aboveground part of crops, including horizontal gene transferal through pollen dispersal and hybridization, has been the focus of research; however, microbial communities in the underground part are attracting increasing attention. In the present study, the soybean root-associated bacterial communities of the G2-EPSPS plus GAT transgenic soybean line Z106, its recipient variety ZH10, and Z106 treated with glyphosate (Z106J) were compared at the seedling, flowering, and seed filling stages by high-throughput sequencing of the V4 hypervariable regions of 16S rRNA gene amplicons using Illumina MiSeq. The results obtained showed no significant differences in the alpha/beta diversities of root-associated bacterial communities at the three stages among ZH10, Z106, and Z106J under field growth conditions; however, the relative abundance of four main nitrogen-fixing bacterial genera significantly differed among ZH10, Z106, and Z106J. Ternary plot results indicated that in the root compartment, the proportional contributions of rhizobial nitrogen-fixing Ensifer fredii and Bradyrhizobium elkanii, which exhibit an extremely broad nodulation host range, markedly differed among the three treatments at the three stages. Thus, the present results indicate that transgenic G2-EPSPS and GAT soybean may induce different changes in functional bacterial species in soil, such as E. fredii and B. elkanii, from ZH10, which were compensated for/enriched at the flowering and seed filling stages, respectively, to some extent through as of yet unknown mechanisms by transgenic soybean treated with glyphosate.
