Written by an eminent group of international researchers, these papers consider the molecular biology underlying nitrogen fixation. They describe the enzymology, biochemical physiology, and electron transport of various nitrogen-fixing plants, including rhizobium and legumes. Expanding and complementing the earlier volumes, this authoritative collection will provide useful, up-to-date reviews for botanists, plant biochemists and physiologists, and agricultural scientists. From reviews of the earlier "A valuable addition to both personal and institutional libraries. Both the beginning student of nitrogen fixation and the well-established veteran will find the reviews enlightening."-- Soil Science. "Convenient and informative."--American Scientist
