Plasticity in Plant-Growth-Promoting and Phytopathogenic Bacteria brings together the expertise of a panel of researchers from around the world to provide comprehensive up-to-date reviews on the most interesting aspects of genomic and phenotypic plasticity in plant-beneficial and phytopathogenic bacteria. The book covers various topics, including common and specific features in the genomes of symbiotic, plant-growth-promoting, and phytopathogenic bacteria; regulation of conjugative plasmid transfer in rhizobia; genetic and phenotypic variability in plant-beneficial pseudomonads and azospirilla; genomic fluxes in phytopathogenic xanthomonads and pseudomonads; genome plasticity in obligate parasitic Phytoplasmas; comparative genomics of plant-growth-promoting and phytopathogenic Herbaspirillum species; horizontal gene transfer in planta and microevolution of plant-associated bacteria in the phytosphere. Plasticity in Plant-Growth-Promoting and Phytopathogenic Bacteria is recommended for all microbiology and plant biology laboratories.
