Biochemistry of Metal Micronutrients in the Rhizosphere focuses on chemical factors and biological activities that control the uptake and translocation of essential metal micronutrients by plants and microorganisms. Emphasis is placed on current proposals describing the roles of microorganisms in controlling the biological activities of metal micronutrients in the rhizosphere. Coverage includes basic principles of siderophore-mediated Fe acquisition by microorganisms, siderophores as important regulators of Fe availability to plants and rhizosphere microorganisms, and microbial control of metal micronutrient supply to plants.
The book evaluates plant uptake processes of Fe, Mn, and Zn in solution cultures and integrates this information with a rapidly developing understanding of rhizosphere events. Important consideration is given to the roles of metal ion chelation and soil chemistry in these biological activities. The current understanding of the biochemical events associated with Fe-deficiency in plants is discussed, including how these activities mediate micronutrient availability to both plants and soil microorganisms. This unique mixture of detailed coverage of the events that control biological activities of Fe, Mn, and Zn in the rhizosphere makes this book an essential reference.
