Front Cover: Nitrogen deficiency modulates carbon allocation to promote nodule nitrogen fixation capacity in soybean (EXP2 2/2024)

Abstract

Mineral nitrogen deficiency in soil would promote sucrose supply to nodules from roots, and then elevate nodule energy state. Nodule energy sensors can sense the elevated nodule energy state to enhance N₂ reduction to plant-usable NH₃ in nodules. This study will be helpful to design leguminous crops with improved adaptation to fluctuating usable nitrogen supplies in the soil.
