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.
