Inorganic Nitrogen in Plants and Microorganisms summarizes new experimental data, ideas and conclusions on the whole metabolic spectrum: - transport through the cell membranes, - the distribution within plant organs, - nitrate and nitrite reduction with their complicated genetic and physiological regulation, - the assimilation of ammonium and dinitrogen. Short reviews cover the dissimilatory reduction of the various inorganic nitrogen intermediates by bacteria, genetic regulation, and ecological and environmental problems. Inorganic Nitrogen in Plants and Microorganisms will help readers understand recent developments in the field of inorganic nitrogen uptake and metabolism.
