Excessive application of chemical fertilizers and other agrochemicals can cause large imbalances in soils and agricultural ecosystems. In this context, mycorrhizae represent a viable solution to mitigate these negative effects. Arbuscular mycorrhizae are vital symbionts due to the multiple benefits they bring to both crops and the entire agroecosystem. The main purpose of this study was to observe whether differentiated fertilization has an influence on mycorrhizal colonization patterns in corn. Observed frequencies and intensities of colonization varied widely between phenophases and treatments, with 20% variation for frequency and 14% for intensity, which implies the constant development of both partners during the vegetation period. Arbuscules and vesicles were present in all development stages, but the overall mean was lower than 4% for arbuscules and 1% for vesicles in the analyzed root fragments. Intensity was highly correlated with frequency of colonization compared with arbuscules, where the coefficient was 0.54, and vesicles, with a coefficient of 0.16. Both PCA and NMDS provided good graphical solutions, with a high resolution due to explained variance and good spatial position of vectors. The use of mycorrhizal maps permits the full exploration of colonization patterns and fungal strategy, and the assessment of mycorrhizae-free areas. For the untreated variant, the strategy was oriented toward a longitudinal colonization followed by an irregular development of hyphae with multiple non-colonized areas. Treatment acts to stimulate the appearance of mycorrhizal spots, which further develop radially.

“…acutiserrata (low elevation) (1503 m), Quercus wutaishanica (low-mid elevation) (1915 m), Betula albosinensis (mid elevation) (2451 m), Abies fargesii Franch (mid-high elevation) (2753 m), Larix chinensis Beissn (high elevation) (3182 m). We randomly selected three sampling points with similar geographic features 20 ×20 m at each elevation gradient, and the method of investigation of vegetation features was described in our previous studies ( Zhao et al., 2015 , 2020 ), in which top soil (0–10 cm) was collected and transported by frozen carbon dioxide. Fresh soil was sieved (2 mm) and homogenized to remove fine heel and other plant debris.…”

“…Soil pH was measured in a deionized water suspension (water-soil ratio of 2.5:1) using a pH meter (Mettler Toledo FE28) ( Zhang et al., 2016 ). Soil organic carbon (SOC) was determined by the K 2 Cr 2 O 7 oxidation method ( Vance et al., 1987 ), total nitrogen (TN) was determined by the Kjeldahl method ( Zhao et al., 2019 ), and total phosphorus (TP) was determined by the colorimetric method (UV spectrophotometer; SHIMADZU UV-2600i/2700i) after wet digestion with HClO 4 -H 2 SO 4 ( Ren et al., 2016 ), Available phosphorus (AP) was extracted by the NaHCO 3 and then measured by UV Spectrometer Subsystem (SHIMADZU UV-2600i/2700i) ( Zhao et al., 2020 ).…”

Background Ferula sinkiangensis is an increasingly endangered medicinal plant. Arbuscular mycorrhiza fungi (AMF) are symbiotic microorganisms that live in the soil wherein they enhance nutrient uptake, stress resistance, and pathogen defense in host plants. While such AMF have the potential to contribute to the cultivation of Ferula sinkiangensis, the composition of AMF communities associated with Ferula sinkiangensis and the relationship between these fungi and other pertinent abiotic factors still remains to be clarified. Results Herein, we collected rhizosphere and surrounding soil samples at a range of depths (0–20, 20–40, and 40–60 cm) and a range of slope positions (bottom, middle, top). These samples were then subjected to analyses of soil physicochemical properties and high-throughput sequencing (Illumina MiSeq). We determined that Glomus and Diversispora species were highly enriched in all samples. We further found that AMF diversity and richness varied significantly as a function of slope position, with this variation primarily being tied to differences in relative Glomus and Diversispora abundance. In contrast, no significant relationship was observed between soil depth and overall AMF composition, although some AMF species were found to be sensitive to soil depth. Many factors significantly affected AMF community composition, including organic matter content, total nitrogen, total potassium, ammonium nitrogen, nitrate nitrogen, available potassium, total dissolvable salt levels, pH, soil water content, and slope position. We further determined that Shannon diversity index values in these communities were positively correlated with total phosphorus, nitrate-nitrogen levels, and pH values (P < 0.05), whereas total phosphorus, total dissolvable salt levels, and pH were positively correlated with Chao1 values (P < 0.05). Conclusion In summary, our data revealed that Glomus and Diversispora are key AMF genera found within Ferula sinkiangensis rhizosphere soil. These fungi are closely associated with specific environmental and soil physicochemical properties, and these soil sample properties also differed significantly as a function of slope position (P < 0.05). Together, our results provide new insights regarding the relationship between AMF species and Ferula sinkiangensis, offering a theoretical basis for further studies of their development.
