“…At the same time, the co-occurrence relationship of bacterial community in the rhizosphere of S. glauca is more complex, and the interconnected network is denser (Figure 5), indicating that its rhizosphere soil may have a more refined metabolic regulation relationship. Many studies have shown that the life activities of plant rhizosphere microorganisms exert an important influence on improving soil properties and promoting the benign development of the plant-microbe symbiosis system (Gutknecht et al, 2006;Mendes et al, 2013;Lynch, 2019;Bhuyan et al, 2020;Trivedi et al, 2020). Based on the above analysis of the key material cycle process of the rhizosphere dominant bacterial community participating of S. glauca in TCSS, the predictive path of action is proposed such that the bacterial community in rhizosphere of S. glauca promotes the benign development of TCSS soil by enriching and enhancing the C/N cycles (Figure 7).…”

In the exploitation and development of the muddy coastal zone in Lianyun New Town, Jiangsu Province, much coastal silt soil (CSS) has been formed through reclamation projects, which is difficult to use. The proportion of wild Suaeda glauca increased significantly and became a dominant species in CSS modified by sea-sand mulching (Treated CSS, TCSS), but it was still affected by saline-alkali stress. To use S. glauca efficiently to improve TCSS, high-throughput sequencing technology and conventional soil analysis methods were adopted to investigate the rhizosphere microbial community structure of S. glauca and the physico-chemical properties of TCSS as well as its internal correlation. The results showed that TCSS had low organic matter content, poor nutrients such as N and P, and poor fertility retention. TCSS was still affected by mild or moderate saline-alkali stress, and the total Ca was greater than 1%, so the soil properties indicated a calcareous saline-alkali soil. The growth of S. glauca can reduce soil salinity and increase soil TN content, and its rhizosphere bacterial community was significantly different from that of bulk soil without S. glauca: the rhizosphere was significantly enriched with C-cycle-related bacterium such as organic matter degrading bacteria mariniflexile, photobacterium Sphingomonadaceae, and N-cycle-related bacterium such as nitrogen-fixing bacteria Azoarcus, denitrifying bacteria Pseudomonadaceae; the symbiotic relationship of rhizosphere bacterial community in S. glauca tended to be more complicated, and the functions of nitrogen-respiration, photo-nutrition, and methyl-nutrition were enhanced. Based on the above results, it is reasonable to predict that the interaction between S. glauca and its rhizosphere bacteria in TCSS could promote the process of soil carbon and nitrogen cycles, as to accelerate soil substance transformation and increase soil fertility, thus driving the benign development of TCSS. The results lay a theoretical basis for developing muddy coasts and promoting the precise improvement of TCSS by large-scale cultivation of S. glauca in the local area.

“…The microorganisms related to Sb-resistance, carbon, nitrogen, phosphorus and sulfur cycling in Sb mining sites have been suggested to promote the bioremediation of Sb pollution ( Sun et al, 2017 ; Li Y. et al, 2021 ). The recruitment of these rhizosphere microorganisms can strengthen the connection between plants and soil ecosystem processes, promote the formation of specific rhizosphere system ( Park et al, 2023 ), and enhance the nutrient cycle, metal resistance, and establishment of plant communities ( Bhuyan et al, 2020 ). Hence, the dominant indigenous plants may benefit from the supplement and assembly of closely related microorganisms that experience the same antimony stress environment.…”

Dominant native plants are crucial for vegetation reconstruction and ecological restoration of mining areas, though their adaptation mechanisms in stressful environments are unclear. This study focuses on the interactions between dominant indigenous species in antimony (Sb) mining area, Artemisia lavandulaefolia and Betula luminifera, and the microbes in their rhizosphere. The rhizosphere microbial diversity and potential functions of both plants were analyzed through the utilization of 16S, ITS sequencing, and metabarcoding analysis. The results revealed that soil environmental factors, rather than plant species, had a more significant impact on the composition of the rhizosphere microbial community. Soil pH and moisture significantly affected microbial biomarkers and keystone species. Actinobacteria, Proteobacteria and Acidobacteriota, exhibited high resistance to Sb and As, and played a crucial role in the cycling of carbon, nitrogen (N), phosphorus (P), and sulfur (S). The genes participating in N, P, and S cycling exhibited metabolic coupling with those genes associated with Sb and As resistance, which might have enhanced the rhizosphere microbes’ capacity to endure environmental stressors. The enrichment of these rhizosphere functional microbes is the combined result of dispersal limitations and deterministic assembly processes. Notably, the genes related to quorum sensing, the type III secretion system, and chemotaxis systems were significantly enriched in the rhizosphere of plants, especially in B. luminifera, in the mining area. The phylogenetic tree derived from the evolutionary relationships among rhizosphere microbial and chloroplast whole-genome resequencing results, infers both species especially B. luminifera, may have undergone co-evolution with rhizosphere microorganisms in mining areas. These findings offer valuable insights into the dominant native rhizosphere microorganisms that facilitate plant adaptation to environmental stress in mining areas, thereby shedding light on potential strategies for ecological restoration in such environments.
