Nitrate Transport Processes and Compartmentation in Root Systems

  • W. A. Jackson
  • R. J. Volk


During normal growing conditions, most higher plants in the vegetative stage tend to accumulate nitrate in the unreduced form in their root tissues and in their above-ground conducting tissues. Under certain stress conditions, this tendency is accentuated (Maynard et al., 1976). Accumulated nitrate thus serves as a storage deposit to sustain growth processes during subsequent periods when stresses are relieved, when the ambient supply becomes limited, or when reproductive growth creates demands for reduced nitrogen which exceed the nitrate uptake rate.
