“…As a result, the increased diversity indices of AM fungi were positively correlated to the soil nutrient levels (Table 3). This finding is in accordance with several other reports (Alguacil, Torrecillas, García-Orenes, & Roldán, 2014;Liu et al, 2020),…”

Organic amendments are powerful tools for mitigating land degradation, improving soil fertility and biodiversity. Nevertheless, changes in the diversity and activity of arbuscular mycorrhizal (AM) fungi during the initial period of soil restoration under different organic amendments (e.g., crop residues and livestock manure) remains poorly understood despite their growing roles in improving soil sustainability. We conducted a six-month experiment with the application of rice straw (RS), horse manure (HM), and both amendments (RH) to an artificially degraded field in Eastern China, and the AM fungal community structure was assessed through Illumina sequencing. The dominance (35.2%) of the identified operational taxonomic units (OTUs) belonged to Glomus, whereas the majority (66.0%) of the recovered sequence reads belonged to Paraglomus. Although no notable changes in AM fungal abundance were observed, the relative abundance of Claroideoglomus significantly increased (p < .05) to 4.3% in the HM-treated soil compared with that in the control (0.1%), and Acaulospora was only detected in the three treated soils. In addition to shaping AM fungal communities, the RH appeared to be the strongest treatment for increasing AM fungal diversity, alkaline phosphatase activity, and glomalin-related soil protein (GRSP) concentrations, and these parameters were positively correlated (p < .05) with edaphic factors, notably the organic carbon concentration. Furthermore, GRSP could be used as an ecological indicator of AM fungal functioning. This study highlights that the combined application of crop residues and livestock manure could have synergistic effects that help to ameliorate the community structure and diversity of AM fungi in degraded fields.

“…Additional fungal communities were negatively correlated with TN, TP, and TK (Table 3). Previous findings have discovered that chemical fertilisation significantly decreases the diversity of the arbuscular mycorrhizal fungal community structures and is negatively correlated with increased soil nutrients (Liu et al, 2020). As noted above, the data in the present study proved that these bacterial and fungal genera may be correlated with the nutrient uptake in the melon plant.…”

“…Biplot of species -environmental variables according to the CCA of bacterial taxa. that the autotrophic nitrification rate in the topsoil layer of UT is significantly higher than that of conventional TL (Liu et al, 2017), which provides a reasonable explanation on the absorption of additional N by the melon plant. TL and P fertilization showed no significant effects on root P contents .…”

No-tillage (UT) and tillage (TL) influence melon (Cucumis melo L.) production. However, the mechanism of improving the soil quality under UT in melon production is still unavailable. In this study, we attempted to explore the effects of UT and TL treatments on soil fertility and the microbial abundance and diversity in planting melon under greenhouse condition. Soil properties were determined and the bacterial v4-v5 16S rRNA and the fungal internal transcribed spacer gene were pyrosequenced by extracting greenhouse soil DNA. Results showed that the two treatments had different effects on nutrient uptake in melon plants under facility conditions. Additional nitrogen (N) was absorbed in the leaves and fruit in UT treatment. However, the N content in the UT treatment was kept as similar to that of the TL treatment. The phosphorus (P) contents in melon plant leaves and fruits in the UT treatment were higher than those in the TL treatment. High potassium (K) contents were observed in fruits and melon stem under the UT and TL treatments, respectively. Soil pH, organic matter and the available N influenced the bacterial and fungal distributions. The total N, total P and total K in melon plants were correlated with the bacterial and fungal groups in facility soils. The UT treatment had a substantial effect on the microbial diversity in soils planted with melon. Our study provided insights into the response of soil fertility and microbial structures to UT and TL treatments under greenhouse soils, which may aid in managing greenhouse soil quality.

“…Particularly, modifications of pH, SOM, TN, and TP under manure amendments may promote AMF root colonization by enhancing AMF spore germination and growth rates. Organic fertilization elevates AMF abundance and shapes the community, which may facilitate symbiose between AMF and plants [14]. The presence of mycorrhiza may favor plant nutrient acquisition by speeding up transformation of organic manure [15].…”

Background The soil mycobiome is composed of a complex and diverse fungal community, which includes functionally diverse species ranging from plant pathogens to mutualists. Among the latter are arbuscular mycorrhizal fungi (AMF) that provide phosphorous (P) to plants. While plant hosts and abiotic parameters are known to structure AMF communities, it remains largely unknown how higher trophic level organisms, including protists and nematodes, affect AMF abundance and community composition. Results Here, we explored the connections between AMF, fungivorous protists and nematodes that could partly reflect trophic interactions, and linked those to rhizosphere P dynamics and plant performance in a long-term manure application setting. Our results revealed that manure addition increased AMF biomass and the density of fungivorous nematodes, and tailored the community structures of AMF, fungivorous protists, and nematodes. We detected a higher abundance of AMF digested by the dominant fungivorous nematodes Aphelenchoides and Aphelenchus in high manure treatments compared to no manure and low manure treatments. Structural equation modeling combined with network analysis suggested that predation by fungivorous protists and nematodes stimulated AMF biomass and modified the AMF community composition. The mycorrhizal-fungivore interactions catalyzed AMF colonization and expression levels of the P transporter gene ZMPht1;6 in maize roots, which resulted in enhanced plant productivity. Conclusions Our study highlights the importance of predation as a key element in shaping the composition and enhancing the biomass of AMF, leading to increased plant performance. As such, we clarify novel biological mechanism of the complex interactions between AMF, fungivorous protists, and nematodes in driving P absorption and plant performance.
