The Mycoplasmas, Volume III: Plant and Insect Mycoplasmas is a volume of a comprehensive three-volume series encompassing various facets of mycoplasmology. It attempts not only to present an extensive and critical review of the rapidly expanding field of plant and insect mycoplasmas, but also to integrate these important subdisciplines into the total field of mycoplasmology. This volume, in particular, shows relevant information on a group of helical mycoplasmas(spiroplasmas), stressing their part in plant and insect diseases. It discusses the tick-borne spiroplasmas and their possible role in vertebrate disease. Other suspected mycoplasmal plant diseases, vector transmission of mycoplasmas and spiroplasmas, and the chemotherapy of mycoplasmal plant diseases are also described. This book will serve as a standard reference work for mycoplasmologists, as well as for other interested microbiologists, cellular and molecular biologists, membrane biochemists, clinicians, veterinarians, plant pathologists, and entomologists.
