“…The rhizosphere is the transit region between the surface of plant roots and the bulk soil in which the physicochemical features are strongly affected by the growth, respiration, and nutrient exchange of roots. Therefore, the microbial abundance, diversity, and activity in the rhizosphere are different from those in the vicinity of bulk soil and endosphere of the root (Xiao et al, 2017a(Xiao et al, , 2019. Numerous studies have demonstrated that plant root exudates mediate the interactions between plant roots and the microbial communities in the rhizosphere; for example, under N-limiting conditions, legumes secrete more flavones and flavonols to attract and initiate a symbiosis with rhizobia (Huang et al, 2014).…”

“…The differences in the microbiome in distinct rhizocompartments (nodule endophytes, root endophytes, rhizosphere, and root zone) of soybean and alfalfa have been revealed by high-throughput sequencing (Xiao et al, 2017a). Meanwhile, the effects of soil type on rhizomicrobiome of Phaseolus vulgaris estimated with a double pot system revealed that the bacterial community in rhizosphere is regulated by long-distance plant signaling (Xiao et al, 2019). These previous studies demonstrated that the root nodules are restricted microhabitats for both the rhizobia and the other bacteria.…”

The effects of nodulation properties of legumes on the rhizosphere bacterial community are still not clear. To determine the effects of nodulation phenotypes on bacterial communities in the rhizosphere of soybean plants, we performed high-throughput sequencing of the 16S rRNA gene to estimate the rhizosphere bacterial community of three soybean lines with different nodulation phenotypes grown in soil supplied with different levels of N fertilizer. The results revealed that both the soybean nodulation phenotypes and the N levels affected the rhizosphere bacteria community, but the nodulation phenotypes contributed more than the N-supply. The diversity of bacteria was decreased in the rhizosphere of super-nodulating phenotype. The response of rhizosphere bacterial communities to the soil available nitrogen (AN) concentrations was different than the response with the three nodulation phenotypes of soybean which was more stable in the wild-type (Nod +) soybean samples than that in the mutant samples (Nod − and Nod ++). Bradyrhizobium in the rhizosphere was positively correlated with nodule number and negatively correlated to AN in the soil, while Burkholderia and Dyella were positively correlated with nodule biomass and nitrogenase activity. These results demonstrated that the nodulation phenotype of soybean affects the rhizosphere microbiome.

“…It has been evidenced that the plant roots could regulate the microbial community in rhizosphere and in root zone; meanwhile, the microbes in soil or in rhizosphere also could regulate the gene expression in plant roots, even in leaves of plants by long distance signal transportation [17]. Based on these interactions among the soil characteristics, the plants and the microbes, a study on microbes associated with the rhizocompartments of F. nitida might reveal the preference of this plant to the root associated microbes, which might be used to estimate their impacts on growth of the F. nitida plants.…”

Fargesia nitida is a cold-resistant evergreen bamboo and is a pioneer plant in the secondary succession after the native trees were destroyed in the eastern Tibetan Plateau. However, little is known about the effects of this plant on soil conditions and about its microbiomes. Aiming at learning the interactions among the soil characteristics, the plants and the microbes in relation to the plant succession, a study on cultivated microbes associated with the rhizocompartments of F. nitida was performed in the present study to reveal the preference of this plant to the root associated microbes, in comparison with that associated with the successive spruce (Picea asperata Mast.) trees. The results demonstrated that growth of F. nitida could improve the soil nutrient contents, especially increasing total nitrogen, NH4+-N, total carbon, and microbial biomass carbon, and maintained more soil bacteria than the successive spruce trees. Based upon the study of F. nitida root-associated cultivated microbial community, the nutrient improvement in F. nitida growing soils might be from the root endophytic bacteria, which presented greater abundance (3.8, 1.7, and 12.6 folds) than that of bacteria in its rhizosphere, root zone soil, and spruce root zone soil, respectively. Pseudomonas members, especially species related to P. baetica and P. vancouverensis, were strongly selected by F. nitida as root endophytes.
