Symbiosis is the fourth volume in the series Cellular Origin and Life in Extreme Habitats (COLE). Fifty experts, from over a dozen countries, review their current studies on different approaches to these phenomena. The chapters present various aspects of symbiosis from gene transfer, morphological features, and biodiversity to individual organisms sharing mutual cellular habitats. The origin of the eukaryotic phase is discussed with emphasis on cyanelles, H syntrophy, N2 fixation, and S-based symbiosis (as well as the origin of mitochondrion, chloroplast, and nucleus). All members of the three domains of life are presented for sharing symbiotic associations. This volume brings the concept of living together as `One plus One (plus One) equals One.' The purpose of this book is to introduce the teacher, researcher, scholar, and student as well as the open-minded and science-oriented reader to the global importance of this association.
Modern methods and approaches, such as the analysis of molecular sequences to infer evolutionary relationships among organisms, have provided vast new sets of data to further our understanding ofliving organisms, but there remain enigmas in the biological world that will keep scientists working and thinking for decades. Microorganisms by virtue of their small size and almost unbounded diversity provide ample examples of intriguing mysteries that are being challenged with all of the techniques the modern scientific arsenal can provide. One whole arena of this battle to resolve puzzling mysteries about various microorganisms is the almost unbelievable ability of many micro-organisms to live in extreme environments. Whether the challenge is extreme heat, cold, pressure, hyper salinity, alkalinity or acidity, some micro-organisms live now where no life might seem possible. This fascinating state of affairs is the context for this present volume edited by Joseph Seckbach. This Volume is a compilation of many of the especially interesting questions and biological challenges that arise in the consideration of microorganisms in general and the extremophiles in particular.
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.

Life As we Know It covers several aspects of Life, ranging from the prebiotic level, origin of life, evolution of prokaryotes to eukaryotes and finally to various affairs of human beings. Although Life is hard to define, one can characterize it and describe its features. The information presented here on the various phenomena of Life were all written by highly qualified authors including scientists, a professional athlete and three Nobel Laureates.
Change and Challenge: My Life After Thirty is the sequel of Chance and Choice, My First Thirty Years (2007). It describes the birth of the author's two sons in the 1950s and the change from her life as a London research biologist to motherhood in rural England. After emigrating to Birmingham, Alabama Joan faced the challenge of raising her sons in a segregated society. In 1963 the Staple family moved to Buffalo, NY; here Joan resumed her research, which involved the 'creation' of living amoebas, as well as witnessing the evolution of a new amoeba strain. Coping with teenagers in the Sixties and starting her teaching career at a Jesuit college complete the story.
The revised Third Edition of The Prokaryotes, acclaimed as a classic reference in the field, offers new and updated articles by experts from around the world on taxa of relevance to medicine, ecology and industry. Entries combine phylogenetic and systematic data with insights into genetics, physiology and application. Existing entries have been revised to incorporate rapid progress and technological innovation. The new edition improves on the lucid presentation, logical layout and abundance of illustrations that readers rely on, adding color illustration throughout. Expanded to seven volumes in its print form, the new edition adds a new, searchable online version.
Aspects of Cell Regulation deals with the various aspects of cellular control mechanisms. The book begins with a discussion of the role of hormones in the control of cell differentiation and biochemical control over the life of an organism. This is followed by separate chapters on an intracellular control problem, namely, the proper reproduction of cellular organelles and their apportionment between daughter cells at cell mitosis; cell mutants with different temporal order for macromolecular synthesis; and the control of a plant enzyme that converts triglycerides into carbohydrate during the early stages of postgerminative growth within seed cotyledon. Subsequent chapters deal with the possible role of mitochondria in changing the control mechanism of cells to that associated with carcinogenesis; the possibility of transforming genes being detectable in the genome after the transformation to neoplastic cell; the correlation between viruses and tumor cells; and whether viruses can originate from cells rather than coming before cells.
