Land use patterns can change the structure of soil bacterial communities. However, there are few studies on the effects of land use patterns coupled with soil depth on soil bacterial communities in the karst graben basin of Yunnan province, China. Consequently, to reveal the structure of the soil bacterial community at different soil depths across land use changes in the graben basins of the Yunnan plateau, the relationship between soil bacterial communities and soil physicochemical properties was investigated for a given area containing woodland, shrubland, and grassland in Yunnan province by using next-generation sequencing technologies coupled with soil physicochemical analysis. Our results indicated that the total phosphorus (TP), available potassium (AK), exchangeable magnesium (E-Mg), and electrical conductivity (EC) in the grassland were significantly higher than those in the woodland and shrubland, yet the total nitrogen (TN) and soil organic carbon (SOC) in the woodland were higher than those in the shrubland and grassland. Proteobacteria, Verrucomicrobia, and Acidobacteria were the dominant bacteria, and their relative abundances were different in the three land use types. SOC, TN, and AK were the most important factors affecting soil bacterial communities. Land use exerts strong effects on the soil bacterial community structure in the soil’s surface layer, and the effects of land use attenuation decrease with soil depth. The nutrient content of the soil surface layer was higher than that of the deep layer, which was more suitable for the survival and reproduction of bacteria in the surface layer.

“…An aliquot of the extracted DNA from each sample was used as a template for amplification. The V3-V4 hypervariable regions of the bacterial 16S rRNA gene were amplified with primers 338F (5'-ACTCCTACGGGAGGCAGCAG-3') and 806R (5'-GGACTACHVGGGTWTCTAAT-3') (Peng et al, 2017). The hypervariable regions of the fungal ITS1 gene were amplified with primers ITS1F (5'-CTTGGTCATTTAGAGGAAGTAA-3') and ITS2 (5'-GCTGCGTTCTTCATCGATGC-3') (White, 1990;Gardes et al, 1993).…”

The production of Camellia oleifera (oil tea), typically planted in acidic red soils in southern China, is limited by low soil fertility. Agro-farming is one way to promote soil fertility by increasing organic matter and microbial communities. To understand the impact of agro-farming activity on soil fertility, three types of agro-farming, namely, raising laying hens under forest (RLH), cultivating Lolium perenne grass under forest (LPG), and maintenance of native grass (MNG), were employed in an oil tea farm with acidic red soil in Changsha, China. Soil samples were collected from the farm to estimate microbial communities, pH, and total organic carbon (TOC) in different seasons. The results indicated that TOC and temperature were the dominant factors influencing the variations of bacterial communities, while temperature and pH affected the fungal communities in the soil. The most abundant bacterial phyla were Acidobacteria, Proteobacteria, Actinobacteria, and Chloroflexi, while the most abundant fungal phyla were Ascomycota, Basidiomycota, and Zygomycota. Regardless of treatment, the bacterial richness and diversity were both low in spring, and the fungal richness and diversity in summer and autumn were higher than in spring and winter. The TOC content and pH in LPG were significantly higher than in other treatments. Microbial communities in LPG and MNG were more stable than in RLH. In summary, cultivating grass under forest treatment was the best way to improve the microenvironment with the highest TOC content and fewer pathogenic microorganisms.

“…Tu et al [18] have investigated bacterial community structure of rhizosphere soils of plants growing in Huixian karst wetland, have found that Proteobacteria was the first dominant babteria with the relative abundance of 42.4% among many dominant bacteria groups. Wang et al [19] have found that Proteobacteria (30.0% of total sequences) was the most abundance phylum in Poyang lake wetland, Jiangxi province, mainly including Alphaprotebacteria (with the value of 7.2%), Betaproteobacteria (with the value of 8.9%), Deltaproteobacteria (with the value of 10.5%) and Gammaproteobacteria (with the value of 2.8%). Our results showed that Proteobacteria was the first dominant bacteria with the relative abundance of 37.77-55.17% in rhizosphere soils of four dominant plants growing in riparian zone of Changtan reservoir, including Salix babylonica,Taxodium distichum, Pterocarya stenoptera and Miscanthus floridulus.…”

“…Class Betaproteobacteria, Gammaproteobacteria and Detaproteobacteria have been reported to play an important role in contaminant removal and decomposition of organic matter. Jiang et al [19] have found the relative abundance of Detaproteobacteria, Betaproteobacteria and Gammaproteobacteria were 19.60%, 6.30% and 5.70% , respectively, in Huixian karst wetland, Guangxi province, China. Our results revealed that the relative abundance of Gammaproteobacteria was the highest in rhizosphere soils of four dominant plants, with the value of 25.30-35.78%, followed by Detaproteobacteria, with the value of 8.70-15.74%, then followed by Betaproteobacteria, with the value of 3.32-7.10%.…”

Soil bacterial play special roles in the maintenance and stabilization of wetland ecosystem. To investigate bacterial community structure and diversity in rhizosphere soils of four dominant plants in riparian wetlands of mountain reservoir in Zhejiang province, the V4+V5 areas of 16S rDNA gene of bacteria were sequenced and analyzed by the Illumina HiSeq 2500 high-throughput sequencing technology. The results indicated that 27 phylums, 70 classes, 144 orders, 218 families, and 370 genuses of bacteria were achieved, with Proteobacteria, Acidobacteria,Actinobacteria and Bacteroidetes being the dominant phylum and Gammaproteobacteria, Deltaproteobacteria, Acidobacteria, Actinobacteria, Betaproteobacteria and Thermoleophilia being the main class in the soils of riparian wetlands in this areas. The Shannon index and chao1 index of the rhizosphere soil bacteria of Salix babylonica were 8.64 and 585.58, respectively, which were the highest among the four plants, and that of Pterocarya stenoptera were the lowest, with 7.71 and 289.63, respectively. Soil pH, total nitrogen and organic matter were the main factors affecting the soil bacterial community structure in the soil rhizosphere of four dominant plants species in wetlands of riparian zone of reservoir in Zhejiang province.
