“…It enables the specific pairing with the AMF species and the target environment. Overall, IAPS changes the compartments into the soil ecosystem by: (1) increasing soil organic matter dynamics (e.g., litter deposition, labile carbon, and SOC) [33]; (2) increasing the soil microbial activity when compared with the noninvaded habitat through functional redundancy process or in other words the “AMF‐host pairing specificity” [10]; (3) increasing nutrient content, thus benefiting plant nutrition, and some microorganisms adapted to fertile soils [34]; (4) by creating positive AMF‐soil‐plant feedback which promotes an adapted cycle for the invader's benefit [35].…”

Invasive alien plant species (IAPS) have the ability to change the biochemical properties and the arbuscular mycorrhizal fungal (AMF) community structure in their rhizosphere. Organic acids, microbial activity, and AMF play a key role in the invader's spread and also has interactions with the soil chemical factors. Our aim here was to assess the rhizosphere's biochemical factors, AMF community composition, and soil chemical properties associated with Cryptostegia madagascariensis (IAPS) and Mimosa tenuiflora (endemic plant species) from the Brazilian Seasonal Dry Forest. The highest values of total glomalin (5.87 mg g−1 soil), root colonization (54.5%), oxalic and malic acids (84.21 and 3.01 μmol g−1, respectively), microbial biomass C (mg kg−1), Na+ (0.080 cmolc kg−1), Ca2+ (7.04 cmolc kg−1), and soil organic carbon (4.59 g kg−1) were found in the rhizosphere of C. madagascariensis. We found dissimilarities on AMF community structure considering the studied plant species: (i) Racocetra coralloidea, Dentiscutata heterogama, Dentiscutata cerradensis, Gigaspora decipiens, and AMF's richness were highly correlated with the rhizosphere of M. tenuiflora; and (ii). The rhizosphere of C. madagascariensis was highly correlated with the abundance of Claroideoglomus etunicatum, Rhizoglomus aggregatum, Funneliformis mosseae, and Funneliformis geosporum. The results of our study highlight the importance of considering C. madagascariensis as potential hosts for AMF species from Glomerales, and a potential plant species that increase the bioavailability of exchangeable Na and Ca at semi‐arid conditions.

“…(2020) identified six bacterial strains that were isolated from the roots of A. adenophora , including B. cereus . Previous research has demonstrated that B. cereus content increased with the invasion process of A. adenophora in the rhizosphere soil ( Sun et al., 2021 ), and the growth of A. adenophora was extensively promoted after adding B.cereus ( Du et al., 2023 ), due to the accumulation of B. cereus could alleviate its autotoxic allelopathy ( Wu et al., 2023 ).…”

Ageratina adenophora can enhance its invasive ability by using beneficial rhizosphere bacteria. Bacillus cereus is able to promote plant growth and provide a positive feedback effect to A. adenophora. However, the interaction between A. adenophora and B. cereus under the influence of native polyphagous insect feeding is still unclear. In this study, Eupatorium lindleyanum, a local species closely related to A. adenophora, was used as a control, aimed to compare the content of B. cereus in the roots of A. adenophora and rhizosphere soil after different densities of Aphis gossypii feeding, and then investigated the variations in the population of A. gossypii and soil characteristics after the addition of B. cereus. The result showed that B. cereus content in the rhizosphere soil and root of A. adenophora increased significantly under A. gossypii feeding compared with local plants, which also led to the change of α-diversity and β-diversity of the bacterial community, as well as the increase in nitrate nitrogen (NO3–N) content. The addition of B.cereus in the soil could also inhibit the population growth of A. gossypii on A. adenophora and increase the content of ammonium nitrogen (NH4+-N) in the soil. Our research demonstrated that B. cereus enhances the ability of A. adenophora to resist natural enemy by increasing soil ammonium nitrogen (NH4+-N) and accumulating other beneficial bacteria, which means that rhizosphere microorganisms help invasive plants defend themselves against local natural enemies by regulating the soil environment.
