“…The diversity indices and community structure of EcM fungi changed with stand aging in the Mu Us Desert, but the effect of forest age was not significant. This was consistent with previous studies that the diversity of the fungal community was not correlated with the aging stand (Wang et al, 2020). As expected, the EcM fungal community was dominated by Basidiomycota rather than Ascomycetes, which is consistent with previous results (Geml et al, 2017).…”

Pinus sylvestris var. mongolica (P. sylvestris) is a pioneer afforestation species for wind and sand fixation in northern China. However, most plantations have undergone unprecedented degradation since the early 1990s. Ectomycorrhizal (EcM) fungi are expected to be substantially related to the degradation of P. sylvestris plantations; however, the direct evidence for this remains unclear. For this purpose, we investigated variation among EcM fungal communities associated with P. sylvestris root samples of three age groups (half-mature, near-mature, and mature) in Mu Us Desert. Our results found a total of 72 EcM fungal operational taxonomic unit (OTU) belonging to Basidiomycota (63) and Ascomycota (9). The EcM fungal community is highly enriched in Rhizopogon, Tuber, Tomentella, and Inocybe, and the variations of their abundance mainly contribute to community differences. The diversity index and fungal species richness showed increasing trends toward the mature forest but did not reach a significant level (p > 0.05). The main factors that affected the dominant EcM fungal community were URE, INV, and SOC, but for the whole EcM fungal community, the effects of soil environments with plantation aging are not significant (p > 0.05). Understanding the effects of environmental factors on the structuring of the EcM fungal communities is critical to sustainable forest management in the future.

Sugarcane farmers commonly use press mud as organic fertilizer to improve the properties of soil and increase crop production. This study compared the effects of press mud on bacterial community structure, bacterial diversity, and physicochemical parameters of sugar mill soil in two sites, the URC Passi Sugar Central and Passi Sugar Central, Inc. both in Panay, Philippines. DNA and soil analyses were conducted to characterize the soil samples with and without press mud from both sites. The results showed that all nutrient contents increased in both areas after press mud application, except in URC Passi Sugar Central, where no increase in phosphorus and sulfur was observed. Bacterial diversity did not significantly increase six months after press mud application. Community pattern results showed that if soil samples within sites were compared, soil with press mud was significantly higher compared to the soil without press mud in terms of OTU richness (Capiz sugar central: 46.00±1.00, 40.00±1.50, respectively; URC Passi Sugar Central: 48.00±0.50, 45.00±0.00, respectively) and carrying capacity (Capiz sugar central: 169±7.36, 125±9.48, respectively; URC Passi Sugar Central: 181±3.80, 162±0.00, respectively) (p<0.05). The same trend was observed in soil samples between sites that were compared. Soil without press mud from URC Passi Sugar Central had a significantly higher compared with soil without press mud of Capiz Sugar Central in terms of OTU richness (45.00±0.00, 40.00±1.50, respectively) and carrying capacity (162±0.00, 125±9.48, respectively) (p<0.05). However, no significant difference was observed in soil with press mud between the two sites in OTU richness, carrying capacity, Shannon, and Evenness analyses (p>0.05). The phylogenetic tree analysis showed that Massilia sp. is closely related to Burkholderia arboris, and Lysobacter sp. is closely related to both Massilia sp.and B. arboris. Generally, press mud application helps increase the available nutrients, diversity, and community patterns in soil, making it good organic fertilizer.

“…Furthermore, bacterial alpha diversity is notably influenced by soil chemical properties, including soil organic carbon (SOC), total nitrogen (TN), and available phosphorus (AP). Our previous study demonstrated that at broader spatial scales, temperature and precipitation primarily drive variations in soil microbial communities within Pinus sylvestris forest [ 28 ]. Notably, bacterial community composition is predominantly influenced by chemical properties, including total nitrogen, soil organic carbon, and pH levels.…”

“…The amplification of the V3–V4 region of the bacterial 16S rRNA gene employed primers 338F (ACTCCTACGGGAGGCAGCA) and 806R (GGACTACHVGGGTWTCTAAT) in a 25 μL system. Purification and quantification procedures adhered to the protocol outlined by Wang et al [ 28 ]. For purification and recovery, magnetic beads (Vazyme VAHTSTM DNA Clean Beads) were added at 0.8 times the volume of the PCR product.…”

Afforestation plays a pivotal role in ecosystem restoration, exemplified by the Saihanba Mechanized Forest Farm, the world’s largest planted forest; however, the assembly mechanisms and interactions of soil microbial communities in such forests remain inadequately understood. This study aimed to elucidate the impact of different afforestation tree species, namely Larix gmelinii var. principis-rupprechtii, Picea asperata, and Pinus sylvestris var. mongolica, on soil bacterial diversity and community structure in comparison to grassland. Sixty soil samples were collected at a 20 cm depth, and high-throughput sequencing was employed to identify bacterial communities and assess their interactions with environmental factors. A total of 6528 operational taxonomic units (OTUs) were identified, with Solirubrobacter, Conexibacter, Bacillus, Massilia, Gaiella, Acidibacter, and Vicinamibacter being the dominant genera. Afforestation significantly impacted soil bacterial alpha diversity, with notable influence from key soil chemical properties, including available phosphorus (AP), cation exchange capacity (CEC), and the carbon-to-nitrogen ratio of soil organic matter (SOM-C/N). The Mantel test highlighted pH, the Normalized Difference Vegetation Index (NDVI), and spatial variable (dbMEM) as primary environmental factors influencing dominant bacterial genera. The bacterial community structure demonstrated deterministic homogeneous selection, wherein SOM-C/N emerged as a significant factor influencing the dissimilarity of soil bacterial communities. Furthermore, plantation soils exhibited a more complex network structure than grassland soil, highlighting the crucial role of bacterial communities in vegetation changes and providing valuable insights into their response to environmental factors during the reforestation process.
