Soil salinization has become the most expansive form of soil degradation in arid and semiarid regions, management is imperative for achieving sustainable development. microorganisms are supposed to play an integral role controlling salinization, effects high-salt environments on microbial community have been widely investigated, but there currently limited comprehensive study taxon co-occurrence patterns assembly processes under different salt intensities. Here, based high-throughput sequencing technologies, we analysed bacterial structure mechanism intensity regions. The results demonstrated that diversity was negatively correlated with salinity, also varied changes intensity. Solonchaks (soils high soluble accumulation) had lowest average degree network, a lower level connectivity correlation among bacteria solonchaks compared other salt-affected soils. highest competitive connections were detected light-intensity saline soils, whereas overall collaborative increased salinity. For network stability, rare taxa (with each taxon’s relative abundance < 0.1%) more essential than abundant (> 1%). As salinity increased, stochastic gradually dominated assembly, dispersal limitation contributed from 45.18% 58.73%. These findings offered valuable information about how affected would be useful salinization.

In global drought-prone cotton-growing (Gossypium hirsutum L.) areas, saline water irrigation has become a key strategy to alleviate the shortage of freshwater resources. Against this backdrop, synergistic effect mineralization degree (MD) and sodium adsorption ratio (SAR) on rhizosphere microecological regulation mechanism remains unclear. To address issue, study constructed an experimental framework interaction between MD SAR, aiming explore their effects bacterial community structure in cotton soil environment. The type area is saline–sodic sandy loam. design, three levels (3 g/L, 5 7 g/L) were set, under each condition, SAR (10 (mmol/L)1/2, 15 20 (mmol/L)1/2) arranged. addition, local was used as control group (CG), resulting total 10 treatment schemes. aim investigate varying communities results indicated that could enhance diversity richness alter its structure.

Evidence shows that biotic and abiotic factors have apparent diversity at different forest ages, leading to changes in rhizosphere microbiomes. However, the difference diversity, co-occurrence pattern, assembly of microbial community among ages is still unclear. A total 24 Juniperus przewalskii soil samples were selected from four representative age classes, using diameter breast height (DBH) as a proxy for tree (age class I: 5 < DBH ≤ 12.5 cm, II: 22.5 III: 32.5 IV: > cm), analyzed structural characteristics by high-throughput amplicon sequencing. With increase class, α-diversity β-diversity had an increased trend. The bacterial Shannon index II III markedly higher than I. From I IV, relative abundances dominant phyla such Actinobacteria Ascomycota decreased, Proteobacteria Basidiomycota contrast. complexity association stability bacteria fungi network structure with age. Stochastic processes mediated communities, while deterministic played more significant role fungal communities. In addition, importance components significantly class. Random forests suggested pH, plant Shannon–Wiener (H), Pielou’s evenness (J) most important driving assembly. Overall, these results provide information useful understanding generation maintenance mechanisms communities across classes.

The Mediterranean area is one of the geographic zones most affected by land degradation and desertification these conditions appear to be even more exacerbated climate change. Based on this idea, work aimed isolate, identify, characterize, select bacterial strains able tolerate salinity drought, which could possibly used in agriculture as plant biofertilizers. sampling rhizosphere soil was performed two Algerian regions, Ghardaïa Djelfa (arid semi-arid zones, respectively) six provinces, targeting fourteen native species, known for their therapeutic use. A total 288 were isolated, identified, characterized growth at different temperatures salt tolerance. capabilities, 95 isolates selected. These underwent further evaluation plant-beneficial traits, including siderophore synthesis, auxin production, phosphate solubilization. Additionally, we assessed impact tomato, cucumber, sorghum seed germination. In a final screening step, nine tested potential growth-promoting activity tomato plants grown semi-controlled conditions. Our results demonstrated that three (Bacillus simplex AH24, Microbacterium arborescens PU10, paludicola AEA23) showed promotion activities tomato.
