“…Using 97% sequence similarity, they were divided into operational classifiers (OTUs). The coverage index (Coverage) and diversity index (Shannon and Chao1) were calculated at the OTU level [39]. As opposed to UNITE (Release 7.0 http://unite.ut.ee/index.php, accessed on 20 April 2023), using BLAST, phylogenetic classifications (phyla, class, order, family, and genus) were determined for sequences that matched 97% of the representative OTU sequences [40,41].…”

Arbuscular mycorrhizal fungi (AMF) are considered to be an essential indicator of ecosystem biodiversity and can increase a plant’s ability to withstand arid conditions. Despite the obvious significance of AMF in the root and rhizosphere system, little is known about how the AMF variety varies between the soil and roots of endangered plants and how this varies depending on habitats in dry and semiarid regions. This study aimed to address this research gap by investigating the characteristics and diversity of AMF colonization in Zygophyllaceae. Using Illumina MiSeq high-throughput sequencing, indigenous AMF in the roots and rhizosphere soil of three endangered plants (Tetraena mongolica, Sarcozygium xanthoxylon, and Nitraria tangutorum Bobr) were investigated. The three threatened plants had different AMF populations in their root and rhizosphere soils, according to a hierarchical clustering analysis. AMF communities in rhizosphere soil were more sensitive to LDA than root AMF communities based on linear discriminant analysis effect size (LEfSe). Glomus, Septoglomus, and Rhizophagus were seen to function as dominant fungi as the soil and root AMF populations carried out their various tasks in the soil and roots as a cohesive collective. Distance-based redundancy analysis (db-RDA) showed that pH, total phosphorus, and accessible potassium were closely associated with AMF communities. The pH of the soil appears to be an important factor in determining AMF community stability. These findings can serve as a guide for the use of AM fungus in the rehabilitation of agricultural land in arid regions. In summary, our work contributed new knowledge for the scientific preservation of these endangered plant species and for the further investigation of the symbiotic link between AMF and endangered plant species.

Background and AimsStudies verify that intercropping in uence the soil aggregates and arbuscular mycorrhizal fungi (AMF), but the characteristics and relationships of AMF communities and soil aggregates at different soil depths have not been fully understood. MethodsA long term positioning experiment starting in 2017, including two-factor experiment of N application level and cultivation. The N application level including N0 (0 kg•hm −2 ) and N2 (240 kg•hm −2 and 80 kg•hm −2 for maize and soybean, respectively). The cultivation, including monoculture maize, monoculture soybean, and maize/soybean intercropping (intercropping maize, intercropping soybean). Soil aggregates and AMF were collected and analyzed from the difference depths soil. ResultsResults showed that intercropping can improve the macro-aggregate (>5 mm) content of maize soil at 0-15 cm and 15-30 cm depth under N0 level. Also, the intercropping can only improve the macro-aggregate content of soybean soil at 0-15 cm depth. Likewise, the results also proved that increasing the N fertilizer application rate can signi cantly decrease the macro-aggregates in intercropping soil at 0-15 cm and 15-30 cm depths. Moreover, intercropping treatment can signi cantly improve the AMF diversity of maize and soybean soil at different depths, while the application of N fertilizer signi cantly reduced the AMF diversity of soil at different depths. ConclusionThe Structural equation modeling indicated that the intercropping system could in uence and participate in the formation of soil aggregates by changing the soil AMF community and relative abundance, thereby contributing the soil stability. These results reveal the mechanisms of improvement of soil quality through diversity planting patterns.
