“…We observed a significant negative correlation between pH and alpha diversity, consistent with Adenan et al (2020), and it verified the claim that pH directly affects the occurrence and population distribution of AM fungi (Adenan et al, 2020;Carvalho et al, 2003). The EC and carbonate content were also negatively correlated with multiple diversity indicators because saline stress limited the spore germination and mycelium growth (Medina et al, 2015).…”

Arbuscular mycorrhizal (AM) fungi are widely distributed in various habitats, and the community composition varies in response to the changing environmental conditions. To explore the response of community composition to the succession of saline-alkali land, soil samples were collected from three succession stages of Songnen saline-alkali grassland. Subsequently, the soil characteristics were determined and the AM fungi in soil samples were analyzed by high-throughput sequencing. Then, the response relationship between community composition and soil characteristics was studied by Canonical correlation and Pearson analyses. The soil properties improved with the succession of saline-alkali grassland. There was no significant difference in alpha diversity between the first and second succession stage (Suaeda glauca and Puccinellia tenuiflora, respectively), and the microbial community had a dense association network at the third stage (Leymus chinensis); in addition, each succession stage had significantly enriched amplicon sequence variants (ASVs) and functional pathways. All the soil properties except cellulase activity had significant effects on community composition. Furthermore, the pH, organic carbon, organic matter, and sucrase activity significantly correlated with alpha diversity indices. These results provide a theoretical basis for realizing the significant changes in AM fungal community and soil properties during the saline-alkali grassland vegetation succession.

“…Some species were replaced by others in drought environments; for example, the genera Scutellospora , Ambispora , Archaeospora , and unclassified_o__Archaeosporales did not emerge in the rhizospheres of Stipa in desert grassland (Sbr4, Sgl7, Skl6, and Stg5). It has been documented that these AMF species are also infrequent in arid regions ( 43 ), which indicates the scarcity of these taxa in highly arid areas where resources are usually limited. The AMF compositions in rhizospheres across the seven Stipa taxa showed fair variance at the OTU level.…”

“…For example, TN, OP, S, Fe, Cu, Zn, and Mn were found to be positively correlated with the Shannon index in rhizosphere soil (Table S5). Studies have demonstrated the significance of soil chemistry and macronutrients for microbial communities in arid and semiarid habitats ( 43 , 48 ). Other studies have agreed that soil phosphorus has a significant role in determining the variety of AMF species in various grassland environments ( 49 ).…”

This study fills a gap in our understanding of the soil arbuscular mycorrhizal fungal community distribution, community composition changes, and diversity of Stipa species along different Stipa population substitution distributions and of their adaptive relationships; furthermore, the differences in the glomalin-related soil protein (GRSP) contents in the rhizospheres of different Stipa species and GRSP’s contribution to the grassland organic carbon pool were investigated. These findings provide a theoretical basis for the protection and utilization of regional biodiversity resources and sustainable ecosystem development.

“…However, no paper reported the AM fungal species in the rhizosphere of V. philippica and it was not clear whether AM fungi were involved in the growth regulation. It is worth noting that pH directly affected the AM fungal diversity and the distribution of some species [17,18]. Therefore, the exploration of V. philippica-AM in different pH conditions would provide a basis for realizing the relationship between AM fungi and the salt tolerance of V. philippica growing in saline-alkali grassland and also for the application of V. philippica-AM symbiosis in salty cities.…”

Arbuscular mycorrhizal (AM) fungi distribute widely in natural habits and play a variety of ecological functions. In order to test the physiological response to salt stress mediated by different AM fungi, Viola prionantha was selected as the host, the dominant AM fungus in the rhizosphere of V. philippica growing in Songnen saline-alkali grassland, Rhizophagus irregularis, and their mixtures were used as inoculants, and NaCl stress was applied after the roots were colonized. The results showed that V. philippica could be colonized by AM fungi in the field and the colonization rate ranged from 73.33% to 96.67%, and Claroideoglomus etunicatum was identified as the dominant AM fungi species in the rhizosphere of V. philippica by morphology combined with sequencing for AM fungal AML1/AML2 target. Inoculation with both the species resulted in the formation of mycorrhizal symbiosis (the colonization rate was more than 70%) and AM fungi significantly enhanced plants' tolerance to salt stress of varying magnitude. Higher activity of antioxidant enzymes and augmented levels of proline and other osmoregulators were observed in AM plants. The content of MDA in CK was higher than that in the inoculations with the stress of 100, 200, and 250 mM. All indices except soluble protein content and MDA content were significantly correlated with AM fungal colonization indices. The analysis for different AM fungal effects showed that the mixtures and R. irregularis worked even better than C. etunicatum. These results will provide theoretical support for the exploration and screening of salt-tolerant AM fungi species and also for the application of AM-ornamental plants in saline-alkali urban greening.
