Mycorrhiza : State of the Art, Genetics and Molecular Biology, Eco-Function, Biotechnology, Eco-Physiology, Structure and Systematics
This third updated and revised edition emphasises strongly on genetics and molecular biology. It contains new chapters, which are written by the leading experts in their respective field of knowledge and expertise.Mycorrhizas are symbioses between fungi and the roots of higher plants. As more than 90% of all known species of plants have the potential to form mycorrhizal associations, the productivity and species composition and the diversity of natural ecosystems are frequently dependent upon the presence and activity of mycorrhizas. The biotechnological application of mycorrhizas is expected to promote the production of food while maintaining ecologically and economically sustainable production systems.
Microorganisms in soils : Roles in genesis and functions
The following key topics are covered: Microorganisms in bioerosion, humification, mineralization and soil aggregation; Microbial energetics and microbes in biogeochemical processes such as carbon and nitrogen cycles and phosphorus bio-availability; Interactions in the mycorrhizosphere, e.g. between mycorrhizal fungi and bacteria; Impact of microbes on plant nutrient cycling and the possible effects of transgenic rhizospheres on soil fungi; Functions of microbes in specific soil compartments such as soil surface or toxic metal polluted soils; Regulation of microbial activities in functional domains that are influenced by biotic or abiotic factors; Use of marker genes and isotopes as examples for modern techniques in soil microbiology.
Microbial Siderophores
"Microbial Siderophores" presents an up-to-date overview of the chemistry, biology and biotechnology of these iron chelators. Following an introduction to the structure, functions and regulation of fungal siderophores, several chapters focus on siderophores of pseudomonads. Here, the technique of siderotyping, which has proved to be a rapid, accurate and inexpensive tool for pseudomonad characterization and identification, is described.
Intestinal Microorganisms of Termites and Other Invertebrates
Soil microorganisms play a major role in the degradation and recycling of organic material. Microbes are involved in the food web and strongly contribute to soil fertility. In the past, attention was mainly directed towards free-living or particle-bound microorganisms, while the role of intestinal microbes of soil animals has been neglected. For the first time, "Intestinal Microorganisms of Termites and Other Invertebrates" focuses on the microbes in gut systems of soil animals. It starts with a profound overview of the biology of soil invertebrates. A major part deals with the gut microbiota of termites, the best investigated gut system of invertebrates. Termites are important soil processors in tropical and subtropical regions. Insight is given into the intestinal microbiota of further relevant primary litter decomposers, such as earthworms, springtails, millipeds, and woodlice. Novel techniques for studying intestinal microbes complete the volume.
Advanced Techniques in Soil Microbiology
"Advanced Techniques in Soil Microbiology" presents a wide range of biotechnological methods for application in soil microbiology analysis. These include all essential methods involving molecular biology, immunology, microbiology, and structural biology, such as transcriptome analysis, RNAi technology, molecular matchmaking, RAPD, T-RFLP and FT/MS. The techniques and procedures have been selected with the aim of offering practical guides for immediate use in the laboratory. The systems investigated range from individual molecules and cells to entire eukaryotic organisms, with a focus on bacteria, fungi, mycorrhiza, and higher plants. This volume of state-of-the-art, practice oriented methods will be of great use both to the first-timer and to the experienced scientist.
