“…Simplicillium and Nectria were the keystone taxa in bulk soil, and Penicillium and Laetisaria in the rhizosphere. Similar findings were reported in previous studies ( Su et al, 2020 ; Liu L. et al, 2021 ; Varsadiya et al, 2021 ; Zheng et al, 2021 ). For instance, Penicillium plays a key role in rhizosphere soil, it can generate products that promote plant health (e.g., soluble phosphorus, iron carriers, plant hormones) and affect plant adaptability through a series of biochemical processes ( Altaf et al, 2018 ; Park et al, 2020 ).…”

Soil fungi play an important role in nutrient cycling, mycorrhizal symbiosis, antagonism against pathogens, and organic matter decomposition. However, our knowledge about the community characteristics of soil fungi in relation to bamboo varieties is still limited. Here, we compared the fungal communities in different soil compartments (rhizosphere vs. bulk soil) of moso bamboo (Phyllostachys edulis) and its four varieties using ITS high-throughput sequencing technology. The fungal α diversity (Shannon index) in bulk soil was significantly higher than that in rhizosphere soil, but it was not affected by bamboo variety or interactions between the soil compartment and bamboo variety. Soil compartment and bamboo variety together explained 31.74% of the variation in fungal community diversity. Soil compartment and bamboo variety were the key factors affecting the relative abundance of the major fungal taxa at the phylum and genus levels. Soil compartment mainly affected the relative abundance of the dominant fungal phylum, while bamboo variety primarily influenced the dominant fungal genus. Network analysis showed that the fungal network in rhizosphere soil was more complex, stable, and connected than that in bulk soil. A FUNGuild database analysis indicated that both soil compartment and bamboo variety affect fungal functions. Our findings provide new insights into the roles of both soil compartments and plant species (including variety) in shaping soil fungal communities.

“…Previous studies have suggested that the microbial networks of healthy soils are more complex than those of diseased soils, indicating that the characteristics of the microbial network play an important role in predicting plant health status [9,10,12]. In the present study, we found that both the complexity and connectivity of microbial networks were greater in RSD-treated soils, indicating that RSD treatment can effectively improve the stability of the soil microbial ecosystem.…”

“…For example, soil microbes are heavily involved in carbon, nitrogen, and sulfur cycling, helping to maintain soil nutrient balance and promote healthy plant growth [8]. Furthermore, a highly-connected microbial community network is a key indicator of soil ecosystem stability and functions to guard against invasion by soil-borne pathogens [9]. Microbial communities in healthy soils are often dominated by beneficial microbes which can release a variety of antimicrobial compounds to suppress plant pathogens [10][11][12].…”

Reductive soil disinfestation (RSD) is an effective practice to eliminate plant pathogens and improve the soil microbial community. However, little is known about how RSD treatment affects microbial interactions and functions. Previous study has shown that RSD-regulated microbiomes may degenerate after re-planting with former crops, while the effect of planting with different crops is still unclear. Here, the effects of both RSD treatment and succession planting with different crops on microbial community composition, interactions, and functions were investigated. Results showed that RSD treatment improves the soil microbial community, decreases the relative abundance of plant pathogens, and effectively enhances microbial interactions and functions. The microbial network associated with RSD treatment was more complex and connected. The functions of hydrocarbon (C, H), nitrogen (N), and sulfur (S) cycling were significantly increased in RSD-treated soil, while the functions of bacterial and fungal plant pathogens were decreased. Furthermore, the bacterial and fungal communities present in the RSD-treated soil, and soil succession planted with different crops, were found to be significantly different compared to untreated soil. In summary, we report that RSD treatment can improve soil quality by regulating the interactions of microbial communities and multifunctionality.

“…The root biomass of Ammophila arenaria increased in the presence of Acremonium relative to the untreated control . A significant negative correlation between the RA of Acremonium and soil morbidity as well as pathogen abundance indicates a potential inhibitory effect of this group of organisms on disease incidence Paenibacillus and Mesorhizobium can improve plant nitrogen fixation capacity. , Additionally, certain bacteria such as Achromobacter and Amycolatopsis can improve plant resistance to pathogenic bacteria. , Pseudomonas promotes plant growth via inhibition of pathogenic microorganisms, synthesis of somatotropic hormones, and enhancement of plant disease resistance .…”

The use of engineered nanomaterials (NMs) as novel antimicrobial agents has garnered significant attention in agriculture. The antimicrobial properties of 5 mg/kg metal oxide (copper oxide and zinc oxide nanoparticles, CuO and ZnO NPs)and carbon (reduced graphene oxide and multiwalled carbon nanotubes, rGO and MWCNT)-based NMs on two soil-borne fungal pathogens, Fusarium oxysporum f.sp. lactucae (F.o.lact) and Fusarium oxysporum f.sp. lycopersici (F.o.lyco), were evaluated over a 21-day incubation period. Both metal-and carbon-based NMs reduced the dehydrogenase activity (DHA) in Fusarium-infested soil by more than 40% relative to the infested controls; the efficacy of antifungal efficacy was CuO NPs > ZnO NPs > rGO > MWCNT. Similar decreases in the soil activities of urease (UE), sucrase (SC), acid phosphatase (ACP), and polyphenol oxidase (PPO) suggest that NMs could effectively inhibit Fusarium growth in soil over time. The total available metal fractions, including acid extractable fraction, Fe/Mn oxidation state, and the fraction bound to organic matter, were increased by 5.99−7.29% with metal-based NM compared to the infested controls. The Shannon index of microbial communities in the infested soils with metal-based NMs was increased by 12.2−23.5% relative to infested controls. Similarly, carbon-based NMs increased the Shannon index of the fungal community by 10.18−29.86%. Importantly, the relative abundance of Fusarium was decreased with both metal-and carbon-based NMs. These NMs also increased the relative abundance of beneficial microorganisms in infested soil, such as Pseudomonas, which was increased by 29.7−96.2% with metal-based NMs relative to the untreated controls. These findings demonstrate that NMs at appropriate doses could inhibit the Fusarium abundance and subsequent crop damage while simultaneously fostering the development of beneficial microorganisms in soil.
