Tropospheric ozone (O 3 ) threatens agroecosystems, yet its long‐term effects on intricate plant‐microbe‐soil interactions remain overlooked. This study employed two soybean genotypes of contrasting O 3 ‐sensitivity grown in field plots exposed elevated O 3 (eO 3 ) and evaluated cause‐effect relationships with their associated soil microbiomes and soil quality. Results revealed long‐term eO 3 effects on belowground soil microb...

Increasing both crop productivity and the tolerance of crops to abiotic and biotic stresses is a major challenge for global food security in our rapidly changing climate. For the first time, we show how the spatial variation and severity of tropospheric ozone effects on yield compare with effects of other stresses on a global scale, and discuss mitigating actions against the negative effects of ozone. We show that the sensitiv...

Both endophytic and mycorrhizal fungi interact with plants to form symbiosis in which the fungal partners rely on, and sometimes compete for, carbon (C) sources from their hosts. Changes in photosynthesis in host plants caused by atmospheric carbon dioxide (CO 2 ) enrichment may, therefore, influence those mutualistic interactions, potentially modifying plant nutrient acquisition and interactions with other coexisting plant sp...

The impact of elevated CO 2 on terrestrial ecosystem C balance, both in sign or magnitude, is not clear because the resulting alterations in C input, plant nutrient demand and water use efficiency often have contrasting impacts on microbial decomposition processes. One major source of uncertainty stems from the impact of elevated CO 2 on N availability to plants and microbes. We examined the effects of atmospheric CO 2 enrichm...
