Soil microbial food web responses to free-air ozone enrichment can depend on the ozone-tolerance of wheat cultivars

► Wheat cultivars are important in determining soil biota responses to elevated [O3]. ► Soil microbial communities were sensitive to elevated [O3] in O3-tolerant cultivar. ► Higher abundance of flagellates was found in O3-tolerant cultivar. ► Nematode functional guilds were sensitive to elevated [O3] and wheat cultivars.
