Drought and elevated tropospheric ozone episodes are expected to be more frequent and severe in the near future. Both are threats to crop yield and food security. In experiments conducted in 2023, two common bean genotypes differing in their sensitivity to ozone, were grown on a natural soil and subjected to drought, elevated ozone or the combination of both stresses, during the seed filling stage. We wondered if the physiological and yield discrepencies between the genotypes were related to their N use efficiency and/or to the structures of their respective rhizospheric microbial communities.
