Energy requirement for nitrogen fixation in actinorhizal and legume root nodules

JD Tjepkema and LJ Winship

The ratio of respiration to nitrogenase activity was measured in five species of actinorhizal root nodules and eight species of legume nodules. The two types of nodules could not be distinguished on the basis of this ratio; this evidence thus indicates that the energy cost of nitrogen fixation is similar for both.
