Regulation of nitrate assimilation in lower plants: a critique
Nitrate assimilation requires the function and regulation of three processes, namely the uptake and translocation of nitrate from the environment into the cell, the reduction of the anion to ammonium via nitrate and nitrite reductases, and the incorporation of the reduced nitrogen into amino acid precursors. All three processes are anabolic and endothermic and, consequently, must be thermodynamically coupled to catabolic and exothermic reactions. While most of the recent research on nitrate assimilation has focused on one or the other of these processes individually, less attention has been given to describing the energy sources required for their function and the regulation of the processes by thermodynamic coupling.
