This book was released on 2013-06-29 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: In symbiosis, different organisms have to recognize each other and exchange material and information. While the functional morphology of symbiont cells has extensively been studied little attention has been paid to mutual interactions and cell-to-cell signals. The main topic of the book is the comparison and discussion of the short-distance signals triggering mutualism in animal and plant cells. Thus it provides a) the basis for a better understanding of various aspects of cell compatibility; b) standardisation of a common vocabulary for animal and plant symbiotic biology; c) optimization of experimental techniques for studying signals in symbiosis. The results show the differences and the general principles in the signalling processes of plant, animal and bacterial cells.

Download or read book The Hologenome Concept Human Animal and Plant Microbiota written by Eugene Rosenberg and published by Springer Science & Business Media. This book was released on 2014-01-31 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundbreaking research over the last 10 years has given rise to the hologenome concept of evolution. This concept posits that the holobiont (host plus all of its associated microorganisms) and its hologenome (sum of the genetic information of the host and its symbiotic microorganisms), acting in concert, function as a unique biological entity and therefore as a level of selection in evolution. All animals and plants harbor abundant and diverse microbiota, including viruses. Often the amount of symbiotic microorganisms and their combined genetic information far exceed that of their host. The microbiota with its microbiome, together with the host genome, can be transmitted from one generation to the next and thus propagate the unique properties of the holobiont. The microbial symbionts and the host interact in a cooperative way that affects the health of the holobiont within its environment. Beneficial microbiota protects against pathogens, provides essential nutrients, catabolizes complex polysaccharides, renders harmful chemicals inert, and contributes to the performance of the immune system. In humans and animals, the microbiota also plays a role in behavior. The sum of these cooperative interactions characterizes the holobiont as a unique biological entity. Genetic variation in the hologenome can be brought about by changes in either the host genome or the microbial population genomes (microbiome). Evolution by cooperation can occur by amplifying existing microbes, gaining novel microbiota and by acquiring microbial and viral genes. Under environmental stress, the microbiome can change more rapidly and in response to more processes than the host organism alone and thus influences the evolution of the holobiont. Prebiotics, probiotics, synbiotics and phage therapy are discussed as applied aspects of the hologenome concept.

Book excerpt: Are humans a galactic oddity, or will complex life with human abilities develop on planets with environments that remain habitable for long enough? In a clear, jargon-free style, two leading researchers in the burgeoning field of astrobiology critically examine the major evolutionary steps that led us from the distant origins of life to the technologically advanced species we are today. Are the key events that took life from simple cells to astronauts unique occurrences that would be unlikely to occur on other planets? By focusing on what life does - it's functional abilities - rather than specific biochemistry or anatomy, the authors provide plausible answers to this question. Systematically exploring the various pathways that led to the complex biosphere we experience on planet Earth, they show that most of the steps along that path are likely to occur on any world hosting life, with only two exceptions: One is the origin of life itself – if this is a highly improbable event, then we live in a rather “empty universe”. However, if this isn’t the case, we inevitably live in a universe containing a myriad of planets hosting complex as well as microbial life - a “cosmic zoo”. The other unknown is the rise of technologically advanced beings, as exemplified on Earth by humans. Only one technological species has emerged in the roughly 4 billion years life has existed on Earth, and we don’t know of any other technological species elsewhere. If technological intelligence is a rare, almost unique feature of Earth's history, then there can be no visitors to the cosmic zoo other than ourselves. Schulze-Makuch and Bains take the reader through the history of life on Earth, laying out a consistent and straightforward framework for understanding why we should think that advanced, complex life exists on planets other than Earth. They provide a unique perspective on the question that puzzled the human species for centuries: are we alone?

Download or read book Microbiology and pathogenesis of Chlamydia Coxiella and Rickettsia written by Rey Carabeo and published by Frontiers Media SA. This book was released on 2024-07-08 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Obligate intracellular parasitism is the associated with genome reduction, which is the process of reconfiguring the genome through systematic elimination of genetic loci deemed unnecessary. The end-result is an increasing dependence on the host for various factors essential for growth, such as nutrients and a protective intracellular replicative niche. The extreme genome reduction that some of the obligate intracellular bacteria have undergone, while maintaining viability and virulence has revealed the level of adaptability, including a plethora of survival strategies that more often than not functionally converge to modulate similar host cell processes, such as cytoskeletal dynamics, vesicular transport, and pathogen recognition, among others. With the advent of molecular genetic approaches, and in the case of Coxiella, growth in axenic media, the field of obligate intracellular pathogen research has progressed rapidly in the past five years, redefining obligate intracellular parasitism as the field transitions from descriptive to mechanism-based research. An emerging theme is the adaptability and ingenuity of this class of pathogens. Genome reduction prioritizes survival, but because this occurs within a host, there is also the need to maintain virulence. As such, survival strategies become intertwined, and likely inseparable from virulence strategies. The purpose of this Special Topics Issue is to bring together in one volume review articles from experts in the field. This issue will have a broad scope. Articles will describe the current state of knowledge in genetics and genomics, metabolism, cell biology of infection, immune evasion, and vaccine design. Importantly, cutting-edge information will also be discussed in the context of past seminal findings, and future directions of research. Overall, this Special Topics Issue should serve as a valuable reference to colleagues and those new to the field of obligate intracellular pathogens research. We welcome submission of review and mini-review articles on the following topics: • Genome structure • Development of genetic tools • Molecular mechanisms of adhesion, invasion, and other early events in infection • Establishment of the intracellular niche • Niche interactions with organelles • Translocation of effectors • Metabolism and metabolic adaptations • Gene regulation during stress response • Pathogen recognition and immune evasion strategies • Innate and adaptive immunity during infection • Experimental models
Download or read book The Rasputin Effect When Commensals and Symbionts Become Parasitic written by Christon J. Hurst and published by Springer. This book was released on 2016-07-05 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on those instances when benign and even beneficial relationships between microbes and their hosts opportunistically change and become detrimental toward the host. It examines the triggering events which can factor into these changes, such as reduction in the host’s capacity for mounting an effective defensive response due to nutritional deprivation, coinfections and seemingly subtle environmental influences like the amounts of sunlight, temperature, and either water or air quality. The effects of environmental changes can be compounded when they necessitate a physical relocation of species, in turn changing the probability of encounter between microbe and host. The change also can result when pathogens, including virus species, either have modified the opportunist or attacked the host’s protective natural microflora. The authors discuss these opportunistic interactions and assess their outcomes in both aquatic as well as terrestrial ecosystems, highlighting the impact on plant, invertebrate and vertebrate hosts.
