“…Both nutrients facilitate plant metabolic processes, and their uptake is supported by AMF [ 51 ]. It is known that high Zn soil levels can negatively affect the abundance and composition of AMF in polluted soils [ 52 , 53 ], while other studies have shown that Zn could influence AMF diversity and richness in non‐polluted ecosystems [ 8 , 16 , 54 ]. These inconsistent results were most likely explained by differences in ecosystem type and structure.…”

“…colonized in plant roots and propagules (spores, etc.) distributed in plant rhizosphere soil [24]. Glomus can form a large network of hyphae and adapt to a wide range of soil pH [25], and it has a rapid regeneration ability, high mycelium turnover rate [26], strong anti-interference ability, and strong tolerance, and can rapidly reconstruct mycelium even after interference [27].…”

“…Lastly, the fourth reason may be related to the reproductive strategy of Glomus, which is widely distributed in diverse ecosystems. Glomus can produce a significant number of propagules that colonize plant roots (hyphae) and are distributed in the plant rhizosphere soil (spores) [24]. Glomus can form an extensive network of hyphae, adapt to a wide range of soil pH [25], and result in a positive correlation between the continuous cropping years of S. grosvenorii and the relative abundance of Glomus.…”

Siraitia grosvenorii, a medicinal plant with continuous cropping, is cultivated in southern China. Changes in the soil microbial community during continuous cropping can cause soil-borne diseases in S. grosvenorii. This experimental study aimed to determine the differences in the arbuscular mycorrhizal fungi (AMF) community structure and root colonization in the rhizosphere soil of S. grosvenorii with different continuous cropping years and altitudes. We tested three altitude gradients (low, 200–300 m; middle, 500–600 m; and high, 700–800 m) and four continuous cropping years (1, 2, 3, and 5 years). AMF colonization, along with AMF spore density, and the soil physicochemical properties of S. grosvenorii roots at different altitudes and continuous cropping years were determined. Illumina high-throughput sequencing was used to determine the molecular diversity of AMF in the rhizosphere of S. grosvenorii as they exhibited a symbiotic relationship. The AMF species in the rhizosphere soil of S. grosvenorii included 28 species of nine genera, including Glomus, Claroideoglomus, Acaulospora, Paraglomus, Ambispora, and so on. With an increasing altitude, the AMF colonization of S. grosvenorii roots increased significantly (p < 0.01); available phosphorus (AP) content was negatively correlated with AMF colonization (p < 0.01). Glomus and Paraglomus were the common dominant genera in the rhizosphere soil of S. grosvenorii planted for 2–5 years at a low altitude and 1 year at middle and high altitudes. The average relative abundance of Glomus increased with increasing continuous cropping years and altitude in the low-altitude and 1-year S. grosvenorii areas, respectively. Slightly acidic rhizosphere soil contributed to AMF colonization and improved the richness and diversity of the AMF community. Our results showed that altitude, AP, and pH are essential factors for predicting AMF infection and community changes in the S. grosvenorii rhizosphere. Here, Illumina high-throughput sequencing was used to study the species resources and community composition of mycorrhizal fungi in S. grosvenorii in the hilly areas of Guangxi, China. This study provides a theoretical basis for the application and practice of mycorrhizal fungi including the isolation and screening of dominant strains, inoculation of mycorrhizal fungi, and exploration of the effects of mycorrhizal fungi on the growth and active ingredients of medicinal plants.

“…It might be accredited to the fact that little availability of P in the soil results in the exudation of few assured chemicals from the plant roots, resulting in the enhancement of AMF establishment and germination of spore, but such exudations are not possible when the phosphorus level is elevated as stated by Lu et al 55 In the current study, AMF diversity indices were negatively correlated with phosphorus. It is find out that species richness and AMF diversity associated with cowpea are negatively correlated to P levels, as observed by Sarr et al 56 There is a strongly positive correlation existing between AMF spore diversity and organic matter and nitrogen levels, as observed by Alimi et al 57 A negative correlation was demonstrated between calcium carbonate and spore density and diversity. Levels of calcium carbonate significantly reduce mycorrhizal symbiosis and influence germination, elongation, and AMF sporulation as found by Palta et al 58 and Posada et al 59 …”

Pulses are considered a remarkable and stable source of nutrients, which are being presently extensively cultivated and consumed in different parts of the world. Pulses belong to the family Leguminosae and are a rich source of nutrients such as phosphorus (P) and nitrogen (N) for best growth via symbiotic relationship with bacteria and AMF (arbuscular mycorrhizal fungi). The aim of the current study was evaluating the influence of AMF diversity associated with various pulses (French bean, mung bean, kidney bean, peas, soybean, peanuts, and grams). Furthermore, AMF characterization was done using morphological features of spores and sequencing of the rDNA gene, which confirmed the existence of 10 different AMF taxa. Among the different genera, the genus Glomus was observed to be the most dominant with 30% species followed by Gigaspora (22%), Sclerocystis (12%), Acaulospora (8%), Rhizophagus and Septoglomus (7%), Diversispora (5%), and Claroideoglomus, Archaeospora, and Ambispora (3%). Furthermore, soil physicochemical analysis and percentage of AMF colonization results revealed the fact that the phosphorus content (inversely proportional to the AMF diversity) was a determining factor of AMF diversity. The highest amount of available phosphorus (62.825 mg kg −1 ) in the district Swabi resulted in a low rate of AMF colonization (6.66 ± 11.54%) with a comparatively higher rate of AMF colonization (50.66 ± 1.15%) found in the soil of the district Chitral having a low phosphorus content (17.3 ± 7.6 mg kg −1 ). Nutrient uptake by pulses including nitrogen (2.4 ± 1.3%), phosphorus (13.5 ± 7.6 mg kg −1 ), potassium (99.5 ± 25.8 mg kg −1 ), zinc (1.4 ± 0.5 mg kg −1 ), moisture (2.3 ± 1.3%), crude fats (5.6 ± 2.8%), ash (4 ± 1.2%), and proteins (13.6 ± 9.01%) determined the fact that AMF species diversity is positively correlated to the plant mineral nutrition. From the current study, it is concluded that AMF inoculation to the soil fields is beneficial to ensure the sustainability and productivity of pulse crops in diverse environmental conditions without polluting the soil.
