Legume nodules have been reported to show CO2-fixing activity as well as N2-fixing activity (1–3). Christeller et al. (2) suggested that the oxalacetate used as the primary carbon skeleton acceptor for ammonium assimilation was provided by the PEP carboxylase reaction rather than via the TCA cycle. In addition, malic enzyme, which required NADPH for carboxylation, was found in Vicia faba nodule cytosol by Lawrie and Wheeler (3).
