“…Our study found that Agaricales, Sordariales, and Tremellales abundance was highly positively correlated to the pH level of the rhizosphere. Similarly, a previous study also found that there is a significant correlation between soil pH and the resident rhizosphere microbial community ( Essel et al, 2019 ). Members of the class Agaricomycetes act as important decomposers, producing both hydrogen peroxide (H 2 O 2 ) and enzymes, resulting in the degradation of complex plant compounds, such as cellulose and lignin ( Kameshwar and Qin, 2016 ).…”

Interactions between plants and microbes can affect ecosystem functions, and many studies have demonstrated that plant properties influence mutualistic microorganisms. Here, high-throughput sequencing was used to investigate rhizosphere and phyllosphere fungal communities during different plant development stages. Results demonstrated that phyllosphere and rhizosphere fungal community structures were distinct during all developmental stages while they were mediated separately by plant carbon and soil sulfur. Comparatively, the effect of root properties on phyllosphere fungal diversity was greater than soil properties. Moreover, rhizosphere fungal networks of Bothriochloa ischaemum were more complex than phyllosphere fungal networks. This study demonstrated that the effect of plant and soil traits on phyllosphere and rhizosphere fungal communities could potentially be significant, depending on the applicable environmental condition and plant development stage. Although links between phyllosphere and rhizosphere communities have been established, further studies on functional fungal groups during phytoremediation processes are necessary. This study comprehensively analyzed dynamic relationships between phyllosphere and rhizosphere fungal communities during different plant development stages in a polluted environment. These fungal communities were determined to be expedient to the development and utilization of beneficial microbial communities during different development stages, which could more effectively help to stabilize and reclaim contaminated copper tailings soil.

“…Soil pH has long been recognized as the main driver of the soil bacterial community [39]. Previous research confirmed that no tillage generally decreased the soil pH, owing to the accumulation of organic matter in the top soil [40,41]. Notably, the soil pH decreased in NT treatment ( Supplementary Table S8) in this study.…”

“…In 2018, we observed significantly lower fungal OTU richness in no-tillage than in deep-tillage systems. Although Degrune et al [48] observed the same results, other studies have shown that tillage practices generally decrease fungal richness [41,49,50], primarily due to the disruption of fungal mycelia. However, fungi also produce asexual or sexual spores in addition to hyphae, conferring greater resistance to tillage disturbance than hyphae.…”

“…Tillage practices, particularly deep tillage, shift soil bacteria-fungi co-occurrence networks towards bacterial domination rather than fungal domination. Fungal-dominated microbial communities are common in less intensively managed land use systems [41] where the intensive land use consistently reduces the biomass of soil fungi and increases the dominance of bacteria [65]. Fungal-dominated communities would result in greater storage of carbon in no-tilled soils [65], while bacteria-dominated communities would drive decomposition and nutrient cycles in the rotary or deep tillage systems [66].…”

Background: Tillage practices and residue management are highly important agricultural practices. However, very few studies have examined the influence of tillage practices and residue management on both bacterial and fungal communities and network patterns in consecutive years. Results: We examined the effects of different tillage practices, including no tillage, rotary tillage, and deep tillage, on the soil bacterial and fungal communities and co-occurrence networks following residue removal and residue retention in 2017 and 2018. This study showed that both bacterial and fungal communities were unaffected by tillage practices in 2017, but they were significantly influenced in 2018. In addition, soil fungal operational taxonomic unit (OTU) richness was significantly enhanced by deep tillage compared with no tillage in 2018, while bacterial OTU richness was unaffected in either year. Tillage practices had differing effects on the soil microbial network patterns, with rotary and deep tillage increasing the complexity of bacterial networks but simplifying fungal networks. However, residue retention only induced a shift in the fungal community in 2018 without an obvious effect in the bacterial community in both years. In addition, residue retention simplified soil bacterial and fungal networks in 2018. Conclusions: This study highlighted the dissimilar responses of bacterial and fungal networks to tillage practices and emphasized that tillage practice is more important than residue management in shaping soil microbial communities.

“… Essel et al (2019) found a significant negative correlation between the abundances of bacteria, such as Holophagae, and pH in a 2-year spring wheat–pea rotation soil annually. In this study, the relative abundance of the class Acidobacteriia from the phylum Acidobacteria in P. notoginseng planting soil bacteria was found to be negatively correlated with the soil pH and CEC ( Table 2 ).…”
