Biology of the Rhizobiaceae covers the genetics, molecular biology, agricultural, and morphological aspects of the rhizobia. The book discusses the taxonomy and identification of the Rhizobiaceae; the biology of Agrobacterium tumefaciens and the specific events in the disease cycle of crown gall; and the agricultural control of Agrobacterium tumefaciens. The text also describes the growth potential of crown gall tumors and crown gall teratoma; plasmid studies in crown gall tumorigenesis; and the biology and microbiology of Agrobacterium rhizogenes. The recognition in rhizobium-legume symbioses; the rhizobium bacteroid state; and the exchange of metabolites and energy between legume and rhizobium are also considered. The book further tackles the mutants of rhizobium that are altered in legume interaction and nitrogen fixation; as well as the significance and application of Rhizobium in agriculture. Botanists, agriculturists, geneticists, molecular biologists, microbiologists, plant pathologists, and agronomists will find the book invaluable.

The Rhizobiaceae, Molecular Biology of Model Plant-Associated Bacteria. This book gives a comprehensive overview on our present molecular biological knowledge about the Rhizobiaceae, which currently can be called the best-studied family of soil bacteria. For many centuries they have attracted the attention of scientists because of their capacity to associate with plants and as a consequence also to specifically modify plant development. Some of these associations are beneficial for the plant, as is the case for the Rhizobiaceae subgroups collectively called rhizobia, which are able to fix nitrogen in a symbiosis with the plant hosts. This symbiosis results in the fonnation of root or stem nodules, as illustrated on the front cover. In contrast, several Rhizobiaceae subgroups can negatively affect plant development and evoke plant diseases. Examples are Agrobacterium tumefaciens andA. rhizogenes which induce the formation of crown galls or hairy roots on the stems of their host plants, respectively (bottom panels on front cover). In addition to the obvious importance of studies on the Rhizobiaceae for agronomy, this research field has resulted in the discovery of many fundamental scientific principles of general interest, which are highlighted in this book. To mention three examples: (i) the discovery of DNA transfer of A.

This book provides in-depth reviews of the role of Rhizobium in agriculture and its biotechnological applications. Individual chapters explore topics such as: the occurrence and distribution of Rhizobium; phenotypic and molecular characteristics of Rhizobium; impact of Rhizobium on other microbial communities in the rhizosphere; N2-fixation ability of Rhizobium; Rhizobium and biotic stress; Rhizobium-mediated restoration of an ecosystem; in silico analysis of the rhizobia pool; further biotechnological perspectives of Rhizobium.

Rhizobia are bacteria which inhabit the roots of plants in the pea family and "fix" atmospheric nitrogen for plant growth. They are thus of enormous economic importance internationally and the subject of intense research interest. Handbook for Rhizobia is a monumental book of practical methods for working with these bacteria and their plant hosts. Topics include the general microbiological properties of rhizobia and their identification, their potential as symbionts, methods for inoculating rhizobia onto plants, and molecular genetics methods for Rhizobium in the laboratory. The book will be invaluable to Rhizobium scientists, soil microbiologists, field and laboratory researchers at agricultural research centers, agronomists, and crop scientists.

This book reviews the history and development of rhizobial ecology (diversity, function and interactions with the biotic and abiotic environments), evolution (genome diversification, systematics of symbiotic genes) and application. Further, it describes the new concept of rhizobia, the latest systematic methods, biogeographic study methods, and genomic studies to identify the interactions between rhizobia, legumes and environments. To enable readers to gain a comprehensive understanding of rhizobial biogeography, the book provides effective protocols for the selection and application of high-efficiency rhizobial inoculants. In addition, it presents standard and modern methods used in studies on rhizobial ecology and evolution in dedicated appendices, making it a unique and valuable handbook for researchers.
