Effect of the Interaction between Elevated Carbon Dioxide and Iron Limitation on Proteomic Profiling of Soybean.

ABSTRACT: Elevated atmospheric CO₂ (eCO₂) and iron (Fe) availability are important factors affecting plant growth that may impact the proteomic profile of crop plants. In this study, soybean plants treated under Fe-limited (0.5 mM) and Fe-sufficient (20 mM) conditions were grown at ambient (400 μmol mol^-1) and eCO₂ (800 μmol mol^-1) in hydroponic solutions. Elevated CO₂ increased biomass from 2.14 to 3.14 g plant^-1 and from 1.18 to 2.91 g plant^-1 under Fe-sufficient and Fe-limited conditions, respectively, but did not affect leaf photosynthesis. Sugar concentration increased from 10.92 to 26.17 μmol g FW^-1 in roots of Fe-sufficient plants and from 8.75 to 19.89 μmol g FW^-1 of Fe-limited plant
