Exploring the bacterial community in the S. glauca rhizosphere was of great value for understanding how this species adapted to the saline-alkali environment and for the rational development and use of saline-alkali soils. In this study, high-throughput sequencing technology was used to investigate the diversity characteristics and distribution patterns of soil bacterial communities in the rhizosphere of S.glauca-dominated communities in the Hetao Irrigation Distract, Inner Mongolia, China. The relationships among bacterial characteristics, soil physicochemical properties and vegetation in four sampling sites were analyzed. The soil bacterial communities in the rhizosphere of S. glauca-dominated communities were mainly composed of 16 phyla (i.e., Proteobacteria, Actinobacteria, Bacteroidetes, Gemmatimonadetes, Chloroflexi, Acidobacteria, Firmicutes, Planctomycetes, Deinococcus-Thermus, Verrucomicrobia, Saccharibacteria, Cyanobacteria, Nitrospirae, JL-ETNP-Z39, Parcubacteria and Chlorobi), and these populations accounted for more than 99% of the total bacterial community. At the genus level, the main bacterial communities comprised Halomonas, Nitriliruptor, Euzebya and Pelagibius, which accounted for 15.70% of the total bacterial community. An alpha diversity analysis indicated that the richness and diversity of rhizosphere soil bacteria differed significantly among the sampling sites, and the bacterial richness and diversity indices of severe saline-alkali land were higher than those of light and moderate saline-alkali land. The principal component analysis (PCA) and linear discriminant analysis effect size (LEfSe) showed significant differences in the species composition of the rhizosphere soil bacterial community among different sampling sites. A correlation analysis showed that the number of bacterial species exhibited the highest correlation with the soil water content (SWC). The richness and evenness indices were significantly correlated with the SWC and SO42–, K+ and Mg2+ concentrations. The electrical conductivity (EC), soluble ions (Na+, CO32– + HCO3–, K+, Ca2+, Mg2+, and SO42+), SWC and vegetation coverage (VC) were the main drivers affecting the changes in its community structure. The bacterial community in the rhizosphere of S. glauca enhanced the adaptability of S. glauca to saline-alkali environment by participating in the cycling process of nutrient elements, the decomposition of organic matter and the production of plant growth regulating substances. These results provided a theoretical reference for further study on the relationship among rhizosphere soil microorganisms and salt tolerance in halophytes.

“…Singh et al [85] achieved slightly higher Salicornia dolichostachya yield in hydroponic systems compared to sand cultivation. For Sueda glauca, a 5.7 kg/ m 2 yield was reported from hydroponic cultivation [86]. Pairing saline agriculture with aquaculture and using halophytes to biofilter effluents has increased interest in recent years, and especially the potential of saline recirculating aquaculture systems (RAS), marine aquaponics, and constructed wetlands have been studied [87][88][89][90].…”

“…The separation of chlorophyll and carotenoids from green protein has been studied; however, it may be hard to justify the use of organic solvents required for pigment removal, especially in large-scale systems targeting food and feed products [116,119]. After protein precipitation, the remaining nutrient-rich juice, often called brown juice, could be used as a fermentation medium to produce organic acids, such as lactic acid, caproic acid, and butyric acid, which are important platform chemicals [86,87,90,91]. An alternative approach is to use the juice for a process aiming for the production of single-cell protein [120].…”

Suaeda glauca and Puccinellia tenuiflora are two important saline-alkali tolerant plants that can improve the soil properties. For exploring the different tolerance mechanisms between them, GC-MS-based metabolomics was used to comprehensively evaluate the primary metabolites response, a total of 51 different metabolites were present in different quantities through PLS-DA score plot analysis. The identified compounds were mainly 11 sugars, 7 amino acids, 5 alcohols and 18 organic acids; they play an important role in responding to the saline-alkali stress and distinguish between S. glauca and P. tenuiflora. All identified metabolites classes showed similar trend to largely accumulate in P. tenuiflora roots and S. glauca shoots, this reveals that the two plants used different physiological strategies to cope with saline-alkali stress. Identified metabolites were annotated to the biological pathways involved in the KEGG database showing that energy and defensive or protective metabolites were highlighted in saline-alkali condition. KeywordsSalt-alkali stress; agroforestry; physiological response; primary metabolites 3 EXPERMENTAL Materials collected S. glauca and P. tenuiflora materials collected from Suaeda glauca community and Puccinellia tenuiflora community of HulunBuir Grassland in China on July, 2017(115°31′00″～121°34′30″, 47°20′00″～50°50′30″). The plants were identified and authenticated by Prof. Mu Liqiang and voucher speciemens were given the numbers SG2365 for S. glauca samples and PT3342 for P. tenuiflora samples and both samples were pressed and saved in room No.
