Elevated ozone enhances the network stability of rhizospheric bacteria rather than fungi

The detrimental effects of elevated ozone (O3) on plants vary by species, and are closely related to soil microbial communities. Soil microbial communities vary in composition depending on the plant species. However, little is known about the effects of O3 on the soil microbiota associated with different plant genotypes in forests. Herein, we applied low O3 (24.7 ppb, charcoal-filtered air (CF-O3)), ambient O3 (58.3 ppb, A-O3), and elevated O3 (99.7 ppb, E-O3) to O3-tolerant and O3-sensitive poplar plants. We found that the compositions of rhizospheric bacterial communities were governed by O3 and poplar genotypes (Adonis, P
