This book addresses multiple aspects of biological clocks in prokaryotes. The first part of the book deals with the circadian clock system in cyanobacteria, i.e. the pioneer of bacterial clocks. Starting with the history and background of cyanobacteria and circadian rhythms in microorganisms, the topics range from the molecular basis, structure and evolution of the circadian clock to modelling approaches, Kai systems in cyanobacteria and biotechnological applications. In the second part, emergent timekeeping properties of bacteria in microbiomes and bacteria other than cyanobacteria are discussed. Since the discovery of circadian rhythms in cyanobacteria in the late 1980s, the field has expl...
Since the discovery of circadian rhythms in cyanobacteria in the late 1980s, the field has exploded with new information. The cyanobacterial model system for studying circadian rhythms, "Synechococcus elongatus", has allowed a detailed genetic dissection of the bacterial clock due to the methods currently available in molecular, structural, and evolutionary biology. This book addresses multiple aspects of bacterial circadian programs: the history and background of the cyanobacteria and circadian rhythms in microorganisms, the molecular basis, structure, and evolution of the circadian clock, entrainment of the oscillator with the environment and the control of downstream processes by the clock, the demonstration of adaptive significance and the prokaryotic clock’s remarkable stability, and mathematical and synthetic oscillator models for clock function. Experts in the field provide a timely and comprehensive review and a stepping-stone for future work on this amazing group of microorganisms and timing.
The Handbook of Behavioral Neurobiology series deals with the aspects of neurosciences that have the most direct and immediate bearing on behavior. It presents the most current research available in the specific areas of sensory modalities. This volume explores circadian rhythms.
In three volumes, historian Jole Shackelford delineates the history of the study of biological rhythms—now widely known as chronobiology—from antiquity into the twentieth century. Perhaps the most well-known biological rhythm is the circadian rhythm, tied to the cycles of day and night and often referred to as the “body clock.” But there are many other biological rhythms, and although scientists and the natural philosophers who preceded them have long known about them, only in the past thirty years have a handful of pioneering scientists begun to study such rhythms in plants and animals seriously. Tracing the intellectual and institutional development of biological rhythm studies, Sh...
The dangers and drawbacks inherent in radioactivity-based methods along with a demonstrated and dramatic increase in sensitivity have precipitated a major shift towards luminescence measurements and visualization techniques. Their use has now spread even to traditional clinical environments, and their applications have grown from clinical assays to
Written by a nurse, this holistic guide for pregnancy and the postpartum experience provides foundational knowledge and intuitive wisdom to help new mothers support the optimal health of their baby and their own bodies. Get the answers to the big questions about pregnancy: • What kinds of foods should you eat and how do you prepare your body for labor and birth? • How does movement impact pelvic health and the baby's position in the womb? • How does the endocrine system and your brain change throughout pregnancy? • How does the microbiome influence your and your baby's health? Packed with practical information and helpful infographics, Amy J. Hammer helps you create the optimal environment for growing a baby and navigating the major transitions in a pregnancy—including nurturing pelvic floor health, the fetal and parental microbiome, and the science behind the stages of pregnancy from conception to postpartum. By providing vital and often ignored information about reproductive science, movement, and nourishment, this book empowers parents to make informed and personal choices about their pregnancy, birth, and beyond.
Melatonin (N-acetyl-5-methoxytryptamine) is a widely studied biomolecule, and its function has been investigated in bacteria, mammals, birds, amphibians, reptiles, fish and plants. Melatonin research in plants the last five years has attained an exponential growth phase and the number of publications related to phytomelatonin has significantly increased in present times. All this research is directed towards establishing multifarious roles of melatonin in plants, including the promotion of seed germination and seedling growth, influencing plant development and senescence, alteration of flowering and fruiting time and grain yield, modulating circadian rhythms, improving resistance against bio...
In 1995, Signal Transduction Protocols, edited by David A. Kendall and Stephen J. Hill, was published in the Methods in Molecular Biology series. This second edition represents an update to that previous work with an emp- sis on new methodologies that have developed in the last few years. The goal, then and now, is to provide procedures written by experts with first-hand ex- rience in a detail that goes far beyond what is generally encountered in the “methods” section of most journals and thus actually permits a particular p- cedure to be replicated. In addition, we have had as a secondary goal the id- tification of protocols for the assay of general classes of signal transduction compon...
The critically acclaimed laboratory standard for more than forty years, Methods in Enzymology is one of the most highly respected publications in the field of biochemistry. Since 1955, each volume has been eagerly awaited, frequently consulted, and praised by researchers and reviewers alike. Now with more than 300 volumes (all of them still in print), the series contains much material still relevant todaytruly an essential publication for researchers in all fields of life sciences.* Discusses optical instrumentation for imaging, screening and diagnosis in molecules, tissues, and cells* Covers the development and application of optical probes and techniques for imaging and drug screening* Investigates the structure and dynamics of biomolecular systems, screening and drug discovery, and the diagnosis and treatment of disease
This volume provides a comprehensive look at the biology of plastids, the multifunctional biosynthetic factories that are unique to plants and algae. Fifty-six international experts have contributed 28 chapters that cover all aspects of this large and diverse family of plant and algal organelles. The book is divided into five sections: (I): Plastid Origin and Development; (II): The Plastid Genome and Its Interaction with the Nuclear Genome; (III): Photosynthetic Metabolism in Plastids; (IV): Non-Photosynthetic Metabolism in Plastids; (V): Plastid Differentiation and Response to Environmental Factors. Each chapter includes an integrated view of plant biology from the standpoint of the plastid. The book is intended for a wide audience, but is specifically designed for advanced undergraduate and graduate students and scientists in the fields of photosynthesis, biochemistry, molecular biology, physiology, and plant biology.
