Mycoplasma are the smallest free-living prokaryotes lacking a cell wall and are, therefore, highly pleomorphic. This book is a contribution toward an understanding of the complex problems of tree diseases caused by mycoplasma-like organisms and their relatives.

Mycoplasma Diseases of Trees and Shrubs contains the edited papers presented at the Third Working Party meeting organized by Professor Karl Maramorosch at Rutgers University, New Jersey, in August 1979. This book also includes additional chapters by the invited contributors in the meeting. Organized into 15 chapters, this book begins with the isolation, characterization and identification of spiroplasmas and mycoplasma-like organisms. It then describes the various diseases of trees and shrubs, specifically yellows disease, stubborn disease, Paulownia witches' broom disease, mulberry dwarf, blueberry stunt, and sandal spike disease. It also elaborates the control of tree diseases by chemotherapy. This treatise will provide a standard reference work for all interested in plant mycoplasma diseases in forest pathology, entomology, and disease control.

The Mycoplasmas, Volume IV: Mycoplasma Pathogenicity is a collection of essays that discusses the factors involved in recovery of mollicutes. The book presents the importance of mixed infections involving mycoplasmas and other microorganisms. It also demonstrates the importance of mycoplasmal arthritis in veterinary medicine. The text describes the dynamics and physicochemical aspects of adherence. It discusses the interaction of mycoplasmas with lymphoid cells and macrophages. Another topic of interest is the induction of cytotoxic lymphocytes by mycoplasma. The section that follows describes the chemoprophylaxis for mycoplasma diseases in man. The book will provide valuable insights for microbiologists, pathologists, students, and researchers in the field of bacteriology.

The Mycoplasmas,Volume V: Spiroplasmas, Acholeplasmas,and Mycoplasmas of Plants and Arthropods focuses on existing knowledge and recent development in research on spiroplasmas, acholeplasmas, and other mollicutes of plants and arthropods. Organized into 11 chapters, this volume discusses the nutrition, cultivation, ecology, and molecular and cellular biology of spiroplasmas. Because the occurrence of other mollicutes (mycoplasma and acholeplasma) in plant and arthropod environments is not extensively discussed in other volumes, this volume shows the rapid progress in describing the new mollicutes from arthropods and plant surface that they contaminate. Molecular studies of mollicute phylogeny and plant infections incited by the so-called mycoplasma-like organisms are also presented. This book will provide a comprehensive reference source for all mycoplasmologists and a relevant and exhaustive summary of recent advances in the study of spiroplasmas, acholeplasmas, and mycoplasmas in plant and arthropod hosts for microbiologists, cellular and molecular biologists, plant pathologists, and entomologists.

was the result of the efforts of Robert Cleverdon. The rapidly developing discipline of molecular biology and the rapidly expanding knowledge of the PPLO were brought together at this meeting. In addition to the PPLO specialists, the conference invited Julius Marmur to compare PPLO DNA to DNA of other organisms; David Garfinkel, who was one of the first to develop computer models of metabolism; Cyrus Levinthal to talk about coding; and Henry Quastler to discuss information theory constraints on very small cells. The conference was an announcement of the role of PPLO in the fundamental understanding of molecular biology. Looking back 40-some years to the Connecticut meeting, it was a rather bold enterprise. The meeting was international and inter-disciplinary and began a series of important collaborations with influences resonating down to the present. If I may be allowed a personal remark, it was where I first met Shmuel Razin, who has been a leading figure in the emerging mycoplasma research and a good friend. This present volume is in some ways the fulfillment of the promise of that early meeting. It is an example of the collaborative work of scientists in building an understanding of fundamental aspects of biology.

Diseases of Shade Trees provides an introduction to tree diseases for students and others concerned with the care of shade and ornamental trees. Diseases of woody plants fall into two major categories: infectious diseases and noninfectious diseases. Part I of the book presents the infectious pathogens and the diseases they cause. These include bacteria, mycoplasmas, nematodes, seed plants, and viruses. The nature of the fungi is also presented, with separate chapters for leaf, root, rust, stem, and wilt diseases caused by fungi. Wound diseases, which are associated with both fungi and bacteria that invade wounds, are included in this section. Part II deals with noninfectious agents and the diseases they cause. Noninfectious agents are separated into environmental stress, animal injury, and people-pressure diseases. Diebacks and declines—complex diseases, which are often caused by a combination of both infectious and noninfectious agents are also included in this section. Part III on special topics includes discussions of nonpathogenic conditions often mistaken for diseases; diagnosis of tree diseases; and living hazard trees.

This book and its companion, Volume II, concentrate on new procedures--especially those based on the new molecular methodology--developed within the past decade. This volume outlines the approaches, techniques, and procedures applied to cell and molecular biology studies of mycoplasmas. Volume II deals with the new genetic and immunological tools applied to the diagnosis of mycoplasma infections of humans, animals, plants, insects, and all cultures, with particular emphasis on the association of mycoplasmas with the activation of AIDS.

Plants, fungi, and viruses were among the first biological objects studied with an electron microscope. One of the two first instruments built by Siemens was used by Helmut Ruska, a brother of Ernst Ruska, the pioneer in constructing electron microscopes. H. Ruska published numerous papers on different biological objects in 1939. In one of these, the pictures by G. A. Kausche, E. Pfankuch, and H. Ruska of tobacco mosaic virus opened a new age in microscopy. The main problem was then as it still is today, to obtain an appropriate preparation of the specimen for observation in the electron microscope. Beam damage and specimen thickness were the first obstacles to be met. L. Marton in Brussels not only built his own instrument, but also made considerable progress in specimen preparation by introducing the impregnation of samples with heavy metals to obtain useful contrast. His pictures of the bird nest orchid root impregnated with osmium were revolutionary when published in 1934. It is not the place here to recall the different techniques which were developed in the subsequent years to attain the modern knowledge on the fine structure of plant cells and of different plant pathogens. The tremendous progress obtained with tobacco mosaic virus is reflected in the chapter by M. Wurtz on the fine structure of viruses in this Volume. New cytochemical and immunological techniques considerably surpass the morphological information obtained from the pathogens, especially at the host-parasite interface.
