“…In this study, microbial biomass C and N increased under elevated CO 2 , which is in agreement with some elevated CO 2 studies (Jin et al, 2013;Butterly et al, 2016;Panneerselvam et al, 2019). The increase in the microbial biomass C have been associated with higher C inputs or rhizodeposition (Drissner et al, 2007;Cheng et al, 2011), which stimulates microbial growth and increases biomass.…”

Arbuscular mycorrhizal fungi (AMF) help in promoting plant growth and mediating key belowground processes, however, AMF responses to the continuous increase in the atmospheric carbon dioxide (CO2) is yet elusive. This has led to considerable interest in the impacts elevated CO2 on AMF and belowground processes in recent years. The present study investigated the effect of elevated CO2 on AMF sporulation and root colonization and soil microbial properties in the rhizosphere of soybean. The pot experiment consisted of two levels of CO2 (ambient; 350 ppm and elevated; 550 ppm) and three soybean cultivars (TGx 1440-1E, TGx 1448-2F and TGx 1480-2F) conducted in open top chambers, laid out in randomized complete block design, replicated thrice. The results showed that elevated CO2 increased the AMF spore density and root colonization of the soybean cultivars. Elevated CO2 increased the microbial biomass carbon (34.2–45.4%), microbial biomass nitrogen (44.6–54.9%), soil nitrogen (30.3–50.6%), available phosphorus (20.8–45.7%) in the rhizosphere of the soybean cultivars compared to the ambient CO2 . These could have resulted in increased plant biomass, pod number, 100-seed weight and seed yield under elevated CO2 . From the results of this study, increased atmospheric CO2 regulates AMF activities, microbial properties and improve soybean performance. Thus, this study may help to a better understanding of the responses of AMF and belowground process with increasing atmospheric CO2.

“…Furthermore, the significant reduction of AMF sporulation in soil exposed to 700 ppm, showed the threat possessed by elevated CO 2 on the AMF community. A similar report also showed that members of Glomerales decreased in soils exposed to elevated CO 2 concentrations . In this study, those AMF species which decreased under the effect of CO 2 were not identified, for which further studies are required for clarifying this AMF community shift.…”

“…The meta‐analysis of data from 125 studies reveals that elevated CO 2 significantly enhanced rice yield by 20% , but many researchers have focused their research towards above the ground changes in response to elevated CO 2 , but a few findings in rice revealed that the elevated CO 2 favoured below‐the‐ground microbial resources and helps the plant gain more productivity . The recent next generation sequencing analysis indicated that the long term exposure of elevated CO 2 in paddys soil decreased the memebers of Glomerales and increased the memebers of Diversisporales of AMF . Most earlier researchers have used the Glomerales group of AMF and proven their beneficial effects in rice, but their drastic reduction in the soil remains a serious concern.…”

Arbuscular mycorrhizal fungi (AMF), particularly the Glomerales group, play a paramount role in plant nutrient uptake, and abiotic and biotic stress management in rice, but recent evidence revealed that elevated CO2 concentration considerably reduces the Glomerales group in soil. In view of this, the present study was initiated to understand the interaction effect of native Glomerales species application in rice plants (cv. Naveen) under elevated CO2 concentrations (400 ± 10, 550 ± 20, and 700 ± 20 ppm) in open‐top chambers. Three different modes of application of the AMF inoculum were evaluated, of which, combined application of AMF at the seedling production and transplanting stages showed increased AMF colonization, which significantly improved grain yield by 25.08% and also increased uptake of phosphorus by 18.2% and nitrogen by 49.5%, as observed at 700‐ppm CO2 concentration. Organic acids secretion in rice root increased in AMF‐inoculated plants exposed to 700‐ppm CO2 concentration. To understand the overall effect of CO2 elevation on AMF interaction with the rice plant, principal component and partial least square regression analysis were performed, which found both positive and negative responses under elevated CO2 concentration.

“…It also may be due to changes in soil nutrients and clime that lead to the reduction of Acaulospora and enhance the dominance of Glomus, so it shows that Glomus becomes more and more adapted to environmental changes over time (Camenzind et al, 2014). This result proved that as the main participant and regulator of the soil material cycle, AMF could sensitively sense and respond to small changes in the soil ecosystem and also showed that mycorrhizal symbiotes played a critical role in responding to climate change (Shi et al, 2017;Panneerselvam et al, 2020). Bonfim et al (2016) study suggested that Glomus and Acaulospora were the dominant genera in a Brazilian Atlantic forest.…”

Arbuscular mycorrhizal fungi (AMFs) play a vital role in ecosystems, especially in ecosystem variability, diversity, and function. Understanding the AMF diversity, distribution, and their driver at different altitudinal gradients is a benefit for understanding the ecological function of AMF in mountain ecosystems. In this study, we explored the AMF molecular diversity and their distribution from 660 to 3,500 m a.s.l. in Mount Taibai of Qinling Mountains based on high-throughput sequencing technology. A total of 702 operational taxonomic units (OTUs) in 103 species of AMF are isolated from soil samples, which belong to 18 identified and 1 unidentified genus in 10 families. The fungi in the genus of Glomus is the most dominant, with the occurrence frequency of 100% and the relative abundance of 42.268% and 33.048% on the species and OTU level, respectively. The AMF colonization in root could be simulated by a cubic function with the change of altitudes with the peak and trough at a.s.l. 1,170 and 2,850 m, respectively. Further, AMF diversity indices including Sob, Shannon diversity, and Pielou evenness also showed the same cubic function change trends with increasing altitude at OTU and species levels. However, the average values of diversity indices at OTU level are always higher than these at the species level. Based on the OTU level, the highest and lowest values of Shannon and Pielou indices are observed at the altitudes of 1,400 and 2,800 m, respectively. The pattern of AMF community distribution in Mt. Taibai is driven by altitude with the characteristics of more abundance in the medium- to low-altitude than high-altitude areas. In general, abundant AMF molecular diversity and species exit in different elevations of Mt. Taibai, which indicate gradient changes with elevations.
