“…These findings are also in line with our prior studies demonstrating the vulnerability of belowground soil microbiomes associated with O 3 ‐tolerant soybean cultivar ‘Jake’ grown under long‐term eO 3 treatment in the same field‐based fumigation system (Zhang et al., 2023). Notably, this system was implemented with a mono‐cropping practice for the previous five consecutive years (2015–2019) (Burkey et al., 2020; Tisdale, Zentella, et al., 2021).…”

“…This partially aligns with a previous study that demonstrated the role of eO 3 in enhancing the decomposition of both native and newly added organic C (Qiu et al., 2021). Intriguingly, Mortierellaceae functioned as a keystone taxon under eO 3 (Figure S7), indicating their robust adaptability to eO 3 and underscoring their critical role in the consistent decomposition of soil organic C under O 3 stress (Zhang et al., 2023; Zhang, Bonito, et al., 2020).…”

“…Additionally, the adverse impact of eO 3 on plant performance reduces the C input from aboveground leaf litter, belowground root debris and rhizodeposition to the soil (Agathokleous et al., 2020; Andersen, 2003; Xia et al., 2021). This, in turn, significantly affects belowground microbial communities and microbially derived ecosystem multifunctionality, such as decomposition, nutrient cycling, and soil formation and protection (Gu et al., 2023; Loya et al., 2003; Qiu et al., 2021; Zhang et al., 2023). The profound effect of eO 3 on soil C dynamics as well as microbial activities (Simpson et al., 2014; Tisdale, Zentella, et al., 2021; Xia et al., 2021) might be due to eO 3 ‐caused suppression in microbial enzymes involved in C degradation (e.g., β‐glucosidase, ligninase, and cellulase) (Dolker et al., 2020; Larson et al., 2002; Xia et al., 2021) and genes associated with C cycling (He et al., 2014; Li et al., 2013).…”

Tropospheric ozone (O3) threatens agroecosystems, yet its long‐term effects on intricate plant‐microbe‐soil interactions remain overlooked. This study employed two soybean genotypes of contrasting O3‐sensitivity grown in field plots exposed elevated O3 (eO3) and evaluated cause‐effect relationships with their associated soil microbiomes and soil quality. Results revealed long‐term eO3 effects on belowground soil microbiomes and soil health surpass damage visible on plants. Elevated O3 significantly disrupted belowground bacteria‐fungi interactions, reduced fungal diversity, and altered fungal community assembly by impacting soybean physiological properties. Particularly, eO3 impacts on plant performance were significantly associated with arbuscular mycorrhizal fungi, undermining their contribution to plants, whereas eO3 increased fungal saprotroph proliferation, accelerating soil organic matter decomposition and soil carbon pool depletion. Free‐living diazotrophs exhibited remarkable acclimation under eO3, improving plant performance by enhancing nitrogen fixation. However, overarching detrimental consequences of eO3 negated this benefit. Overall, this study demonstrated long‐term eO3 profoundly governed negative impacts on plant‐soil‐microbiota interactions, pointing to a potential crisis for agroecosystems. These findings highlight urgent needs to develop adaptive strategies to navigate future eO3 scenarios.

“…Thus, the elevated O 3 had indirect negative effects on bacterial and fungal communities by soil nutrients. The interactions among plants, soils, and microorganisms played a key role in the biogeochemical cycles [48], the soil microorganisms supporting plant fitness and sustainable ecosystems [49]. A recent review by Agathokleous et al [16] showed that O 3 altered plant properties (such as leaf and root litter input, plant secretions, and root turnover) and soil processes (such as soil enzyme activity and decomposition rate).…”

Near-surface O3 has negative effects on plant productivity; however there were few studies on the effects of O3 pollution on the belowground part of the ecosystem. The effect of O3 stress on the belowground parts of poplar is unclear. We investigated the effects of O3 pollution on poplar rhizosphere soil in open-top chambers (OTC). Two kinds of plants with different O3 sensitivity were selected, i.e., high-sensitive poplar clone 546 and low-sensitive poplar clone 107. The control group and high-concentration O3 group were set up: charcoal-filtered air, CF; unfiltered air + 60 ppb O3, NF. Poplar rhizosphere soil was taken after 96 days (15 June to 17 September 2020) of cultivation in OTCs. O3 stress decreased the amplicon sequence variations (ASVs) of microorganisms in poplar 107 and poplar 546 rhizosphere soil, with no significant interspecific difference. The effect of O3 fumigation on the fungal community was greater than that on the bacterial community. The correlation between the bacterial community and rhizosphere soil physicochemical indices was closer than that of the fungal community. Some fungi, such as Clitopilus hobsonii, Mortierella sp., and Minimedusa, might help poplar resist the O3 stress. O3 stress had direct impacts on the pH, nutrients, and enzyme activities of rhizosphere soil, while it had indirect negative impacts on microbial community composition by nutrients. There was no difference in sensitivity between rhizosphere soil response to O3 stress of poplar clone 107 and clone 546, which might take a longer accumulation time to show the effect. This study provides a certain basis for accurately evaluating the ecological effects of O3 pollution.
