“…However, under extremely harsh conditions, stress‐resistant microbial communities occur. Halomonas anticariensis, involved in the S oxidation process in this study (Figure 6), has certain salt tolerance, which is consistent with the microorganisms involved in the S cycle in the rhizosphere soil of halophytes reported by An et al (2022), indicating that salinization is serious in desert areas. Extracellular polysaccharides secreted by Halomonas anticariensis can form biofilms on the roots of plants, which can effectively colonize plants (Li et al, 2013) and protect host plants from pathogenic bacterial attack and external stress such as salt (Kasim et al, 2016; Xu et al, 2013).…”

“…In our study, many microorganisms overlapped with those in the salt lake environment, which may be because the desert environment around Ebinur Lake is similar in salt to that of a salt lake. Rhizobiales bacterium, Bacteroidetes bacterium, and Labilithrix luteola regulate the enrichment of SO 4 2À to R-SH (Figure 7), among which Bacteroidetes can increase the degradation of organic matter, provide electrons for reducing bacteria, and thus promote efficient cycling; similar results were found in the rhizosphere soils supporting S. glauca and P. australis (An et al, 2022).…”

The sulfur (S) cycle is one of the geochemical element cycles in which microorganisms play a key driving role. The microbial function of soil S cycling in response to desert degradation, however, remains largely unknown. We used metagenomics to analyze the characteristics of microbial communities and their functional genes involved in the S cycles under natural water gradients with three typical halophytes shrubs in the Ebinur Lake basin Desert, China. Our results showed that the rhizosphere effect, water gradient, and halophyte type played a major role in shaping the S cycle. On the whole, in the rhizosphere type and low water environment, the functional genes involved in the S cycle had high abundance, and the sulfur oxidizing protein (SOX) system in Alhagi sparsifolia had a high expression level. In the S cycle network structure, as the soil water content decreased, the complexity in S gene networks increased, showing the characteristics of clustering and high connectivity. Indicates the strengthening mode in microbial interactions with the water content. Interestingly, the negative correlation of the network changed with the water content, and there was more competition among communities under the low water gradient and more cooperation under the high water gradient. Through the correlation between environmental factors and the network, nitrate (NO 3 À ) and soil available S (AS) constrained most S gene ecology networks. The key species involved in the S cycle were halophilic microorganisms. These results can enhance the understanding of soil S biogeochemical processes and contribute to the mitigation of desertification by improving soil conservation.

“…Several recent studies have also explored the potential use of the plant and soil microbiome for enhanced plant tolerance to abiotic stresses, including drought and salinity ( Leontidou et al., 2020 ; An et al., 2022 ; Koshila Ravi et al., 2022 ). In the future, combining GE-based approaches with microbial use may constitute an ecofriendly and sustainable approach for higher agricultural crop productivity.…”

“…The change in community structure sensitively reflects the changes in soil quality, health status, and ecosystem [ 28 – 30 ]. Therefore, the change of microbial community structure can be used as an important ecological indicator to explore the impact of atrazine on soil quality and ecosystem [ 31 ]. Studies have shown that residual atrazine in soil considerably shifted the soil microbial community structure and function, and affected the growth of sensitive crops even at low concentrations [ 32 , 33 ].…”

Bioremediation of atrazine-contaminated soil is considered a safe and effective approach in removing contaminates from the soil. However, the effects of adding foreign organisms to assist bioremediation on soil environmental quality and ecosystem are unclear. Here, the ecological remediation potential of strain Paenarthrobacter ureafaciens ZF1 on atrazine-contaminated soil was investigated through miniature experiments using variations in soil enzymes and bacterial communities as indicators. The results showed that strain ZF1 accelerated atrazine degradation, which could completely degrade atrazine at concentrations of 100 mg·L− 1 atrazine within 2 h in liquid medium and could remove up to 99.3% of atrazine (100 mg·kg− 1 in soil) within 6 days. During soil bioremediation, atrazine promoted the activities of urease and cellulase, and inhibited the activities of sucrase and catalase, while the strain ZF1 significantly promoted the activities of these four enzymes. High-throughput sequencing of 16S rRNA genes showed that ZF1 affected the relative abundance and bacterial community structure, and promoted bacterial diversity and evenness. Furthermore, redundancy analysis revealed a certain correlation among the strain ZF1, atrazine residue, soil enzyme activity, and soil bacterial community. The strain ZF1 in this work demonstrated remarkable potential for ecological restoration, and can be an effective and environmentally friendly alternative in remediating atrazine-contaminated soil.
