Soybean Inoculated With One Bradyrhizobium Strain Isolated at Elevated [CO₂] Show an Impaired C and N Metabolism When Grown at Ambient [CO₂].

ABSTRACT: Soybean (Glycine max L.) future response to elevated [CO₂] has been shown to differ when inoculated with B. japonicum strains isolated at ambient or elevated [CO₂]. Plants, inoculated with three Bradyrhizobium strains isolated at different [CO₂], were grown in chambers at current and elevated [CO₂] (400 vs. 700 ppm). Together with nodule and leaf metabolomic profile, characterization of nodule N-fixation and exchange between organs were tested through ¹⁵N₂-labeling analysis. Soybeans inoculated with SFJ14-36 strain (isolated at elevated [CO₂]) showed a strong metabolic imbalance, at nodule and leaf levels when grown at ambient [CO₂], probably due to an insufficient supply of N by no
