“…This might be due to soil pH differences. Most of the soils tested in other studies were alkaline, whereas the soils in our study were more acidic ( Jiang et al, 2020 ). In general, AMF taxa vary widely within their optimum pH ranges ( Gai et al, 2006 ).…”

“…In addition, host plants also affect the soil AMF community. Jiang et al (2020) revealed that the relative abundance of Glomus and Scutellospora in mango orchards was significantly higher than that in litchi orchards, whereas the relative abundance of Diversispora , Acaulospora , Ambispora , and Paraglomus in litchi orchards were significantly higher. AMF abundance in July was higher than that in December, whereas the results of richness and Chao1 index were opposite ( Xiao et al, 2019 ).…”

“…In general, long-term fertilization has a greater effect on soil properties and microbial communities. In this light, AMF may be influenced by various factors, such as fertilization method, tillage system, soil type, host plant, and sampling time ( Barnes et al, 2016 ; Gu et al, 2020 ; Jiang et al, 2020 ). Most of the previous studies focused on the effects of fertilization on AMF in soil, and there were few studies on the effects of fertilization on AMF in field crop roots.…”

Arbuscular mycorrhizal fungi (AMF) play vital roles in the growth and development of plants, ecosystem sustainability, and stability in agroecosystem, such as transporting nutrients to host plants, improving soil physical structure, and enhancing the stress resistance of host plants. However, the effects of fertilization on AMF diversity and community in brown soil areas are still unclear. The purpose of this study is to explore changes in AMF diversity and community structures and finding out the factors that influenced the changes after 41 years of fertilization in brown soil. Samples were collected from five treatments of the long-term fertilization experiment in June 2019, including CK (no fertilizer), N (mineral nitrogen fertilizer), NP (mineral nitrogen and phosphate fertilizer), M (pig manure), and MNP (pig manure, mineral nitrogen, and phosphate fertilizer). Illumina HiSeq sequencing was used to determine AMF diversity and community structure. The relationship between AMF communities in soil and roots and environmental factors was analyzed by redundancy analysis. The results showed that the soil nutrient content of manure treatments was generally higher than that of chemical fertilizer treatments and no fertilizer treatment. Long-term fertilization increased AMF spore density, which increased with the increase of soil fertility. The moderate content of soil available phosphorus was beneficial to the colonization of AMF. AMF diversity in soil decreased with soil fertility, but AMF diversity in roots was influenced only by soil nitrate–nitrogen and pH. Glomus was the dominant genus in both soil and root samples. AMF community structure in soil and roots had a different response to long-term fertilization. Application of manure had a greater impact on AMF community structure in soil, whereas application of exogenous phosphate fertilizer had a greater impact on that in roots. Soil ammonium nitrogen, nitrate–nitrogen, total nitrogen, organic carbon, total potassium, and available potassium were the most important factors that influenced taxa of AMF in soil, whereas soil ammonium nitrogen, nitrate–nitrogen, total nitrogen, organic carbon, total potassium, available potassium, available phosphorus, and plant phosphorus and potassium content were the most important factors influencing taxa of AMF in maize roots under long-term fertilization in brown soil.

“…Soil AM fungi cannot utilize such organic matter directly (Jin et al, 2005), but the increased amount of organic matter can recruit diverse microbes to decompose organic compounds (Zhong et al, 2010); this phenomenon potentially increases not only photosynthesis but also the allocation of underground C, thereby increasing AM fungal diversity. Alternatively, since the functions of AM fungi may be affected by microbes that colonize their mycelia or spores (Agnolucci, Battini, Cristani, & Giovannetti, 2015), the interactions between AM fungi and other microbes recruited by soil organic C components might be the underlying reason for the increased diversity (Jiang et al, 2020).…”

Application of rice straw and horse manure coameliorated soil arbuscular mycorrhizal fungal community: Impacts on structure and diversity in a degraded field in Eastern China

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.

“…This discrepancy may be due to different host plant species. For instance, a previous study observed that Glomus was most abundant in the rhizosphere soil of mango orchards, whereas Paraglomus was most abundant in the rhizosphere soil of litchi orchards (Jiang et al, 2020). Funneliformis dominated in the rhizosphere soil of five dominant tree species on the Loess Plateau by a detection method of spore morphology (He et al, 2019).…”

Arbuscular mycorrhizal (AM) fungi play a crucial role in promoting plant growth, enhancing plant stress resistance, and sustaining a healthy ecosystem. However, little is known about the mycorrhizal status of teak plantations. Here, we evaluated how the AM fungal communities of rhizosphere soils and roots respond to different stand ages of teak: 22, 35, 45, and 55-year-old from the adjacent native grassland (CK). A high-throughput sequencing method was used to compare the differences in soil and root AM fungal community structures. In combination with soil parameters, mechanisms driving the AM fungal community were revealed by redundancy analysis and the Mantel test. Additionally, spore density and colonization rates were analyzed. With increasing stand age, the AM fungal colonization rates and spore density increased linearly. Catalase activity and ammonium nitrogen content also increased, and soil organic carbon, total phosphorous, acid phosphatase activity, available potassium, and available phosphorus first increased and then decreased. Stand age significantly changed the structure of the AM fungal community but had no significant impact on the diversity of the AM fungal community. However, the diversity of the AM fungal community in soils was statistically higher than that in the roots. In total, nine and seven AM fungal genera were detected in the soil and root samples, respectively. The majority of sequences in soils and roots belonged to Glomus. Age-induced changes in soil properties could largely explain the alterations in the structure of the AM fungal community along a chronosequence, which included total potassium, carbon-nitrogen ratio, ammonium nitrogen, catalase, and acid phosphatase levels in soils and catalase, acid phosphatase, pH, and total potassium levels in roots. Soil nutrient availability and enzyme activity were the main driving factors regulating the shift in the AM fungal community structure along a chronosequence of the teak plantations.
