“…Numerous studies have shown a significant correlation between the decrease in soil pH and the systematic aggregation of Acidobacteria enhancement ( Conradie and Jacobs, 2021 ; Xiao et al, 2023 ). In the HM group, Acidobacteria, including Subgroup_6 in the Acidobacteria taxonomic group, were significantly enriched ( Figure 6B ).…”

Excessive Cd accumulation in soil reduces the production of numerous plants, such as Sophora tonkinensis Gagnep., which is an important and widely cultivated medicinal plant whose roots and rhizomes are used in traditional Chinese medicine. Applying a mixture of biochar and organic fertilizers improved the overall health of the Cd-contaminated soil and increased the yield and quality of Sophora. However, the underlying mechanism between this mixed fertilization and the improvement of the yield and quality of Sophora remains uncovered. This study investigated the effect of biochar and organic fertilizer application (BO, biochar to organic fertilizer ratio of 1:2) on the growth of Sophora cultivated in Cd-contaminated soil. BO significantly reduced the total Cd content (TCd) in the Sophora rhizosphere soil and increased the soil water content, overall soil nutrient levels, and enzyme activities in the soil. Additionally, the α diversity of the soil bacterial community had been significantly improved after BO treatment. Soil pH, total Cd content, total carbon content, and dissolved organic carbon were the main reasons for the fluctuation of the bacterial dominant species. Further investigation demonstrated that the abundance of variable microorganisms, including Acidobacteria, Proteobacteria, Bacteroidetes, Firmicutes, Chloroflexi, Gemmatimonadetes, Patescibacteria, Armatimonadetes, Subgroups_ 6, Bacillus and Bacillus_ Acidiceler, was also significantly changed in Cd-contaminated soil. All these alterations could contribute to the reduction of the Cd content and, thus, the increase of the biomass and the content of the main secondary metabolites (matrine and oxymatrine) in Sophora. Our research demonstrated that the co-application of biochar and organic fertilizer has the potential to enhance soil health and increase the productivity and quality of plants by regulating the microorganisms in Cd-contaminated soil.

“…The experimental plot was flat, with good drainage and irrigation conditions. The prevalent soil type was quaternary red clay [1]. Before planting, the method [1,3] previously described was used to measure the chemical properties of soil as follows: soil pH 5.87, soil organic matter (SOM) 28.03 g kg −1 , total nitrogen (TN) 1.48 g kg −1 , total phosphorus (TP) 0.87 g kg −1 , total potassium (TK) 9.54 g kg −1 , alkaline nitrogen (AN) 123.67 mg kg −1 , available phosphorus (AP) 47.67 mg kg −1 , and available potassium (AK) 272 mg kg −1 .…”

Background Endophytes are reported to play a role in resistance against plant pathogens. Understanding the metabolite-mediated endophytic microbiota composition in plants provides insights to improve plant stress resistance. In this study, via metabolome and microbiome analyses, we aimed to elucidate the resistance mechanism of sugarcane cultivars with high resistance to sugarcane pokkah boeng disease (PBD). The endophytic microbial composition and metabolites in the stems of various sugarcane cultivars with high resistance (HR) or high susceptibility (HS) to PBD were analyzed. Results The results revealed that the endophytic fungi with biocontrol effects such as Shinella, Dechloromonas, and Microbacter were significantly enriched, and the abundance of pathogenic fungi such as Fusarium, Ramichloridium, Scleroramularia, Phaeosphaeriopsis, Sarocladium, Zygophiala, Gibberella, Pseudocercospora, Cyphellophora, Monocillium, Apiotrichum, Microsphaeropsis, and Scleroramularia significantly reduced in the stems of HR cultivars. Additionally, six metabolites [citric acid, isocitrate, malic acid, PC(16:0/0:0), phosphocholine, and lysoPC(16:0)] were significantly related to the endophytes in the stems of HR cultivars. Conclusions These results suggested that more abundance of antagonistic microbes and highly active metabolic functions of endophytes in the HR cultivars were the important mechanisms underlying their higher resistance to PBD.

“…Soil microorganisms, particularly bacteria and fungi, occupy a pivotal position in terrestrial ecosystems, mediating nutrient cycling, material transformation, energy flow, and information transfer [ 24 , 25 ]. Bacteria, the most populous and diverse microbial group in soil [ 26 ], contribute significantly to the mineralization of organic debris, the sequestration of humus within the soil mineral layer, and the facilitation of the carbon and nitrogen cycles, ultimately enriching plant growth with essential nutrients [ 27 , 28 , 29 , 30 ].…”

Extensive management seriously affects the output, quality, and sustainable development of star anise, and grafting is commonly used to improve its production and quality. Although many studies have explored the effects of grafting on soil microorganisms for other plants, there is a lack of research on aromatic plants, especially on the soil ecosystems of star anise plantations. The effect of grafting star anise on the soil’s biological characteristics and microbial composition remains unclear. The soil’s enzyme activities, soil microbial biomass, and microbial community composition in grafted and non-grafted star anise plantations in Guangxi, China were studied using high-throughput sequencing technology. The results showed that the microbial biomass carbon and phosphorus contents in the soils of grafted star anise were significantly lower and the phosphatase activity was significantly higher than in the soils of non-grafted star anise. In comparison with the soils of non-grafted star anise plantations, the proportions of Proteobacteria, Acidobacteria, Actinobacteria, and WPS-2 decreased and the proportions of Chloroflexi, Planctomycetes, and Verrucomicrobia increased in the grafted star anise plantations. Meanwhile, Bacteroidetes was a dominant bacterial phylum unique to the soil of the grafted star anise plantations. Moreover, the proportions of Ascomycota and Basidiomycota increased and the proportions of Mortierellomycota and unclassified_k_Fungi decreased in the soils of the grafted star anise plantations. Furthermore, Basidiomycota and Rozellomycota had significant dominance in the grafted star anise plantations. In general, grafting can improve soil fertility and maintain soil health by promoting soil nutrient cycling and increasing the soil’s microbial diversity.
