Biological Rhythms and Photoperiodism in Plants brings together disparate subject areas into one accessible text of interest to all plant biologists. In this comprehensive volume, leading international researchers review our current understanding of circadian rhythms from a broad perspective. The book begins with a description of well known rhythmic processes such as gene expression, stomatal guard cell opening, and the movement of petals and leaves. Photoperiodic responses such as dormancy, bulbing, tuberization and flowering are then discussed in terms of their rhythmic behaviour. The latest data from current studies with mutant and transgenic plants is also included.

Life evolves in a cyclic environment, and to be successful, organisms must adapt not only to their spatial habitat, but also to their temporal habitat. How do plants and animals determine the time of year so they can anticipate seasonal changes in their habitats? In most cases, day length, or photoperiod, acts as the principal external cue for determining seasonal activity. For organisms not living at the bottom of the ocean or deep in a cave, day follows night, and the length of the day changes predictably throughout the year. These changes in photoperiod provide the most accurate signal for predicting upcoming seasonal conditions. Measuring day length allows plants and animals to anticipate and adapt to seasonal changes in their environments in order to optimally time key developmental events including seasonal growth and flowering of plants, annual bouts of reproduction, dormancy and migration in insects, and the collapse and regrowth of the reproductive system that drives breeding seasons in mammals and birds. Although research on photoperiodic time measurement originally integrated work on plants and animals, recent work has focused more narrowly and separately on plants, invertebrates, or vertebrates. As the fields have become more specialized there has been less interaction across the broader field of photoperiodism. As a result, researchers in each area often needlessly repeat both theoretical and experimental work. For example, understanding that there are genetically distinct morphs among species that, depending on latitude, respond to different critical photoperiods was discovered separately in plants, invertebrates, and vertebrates over the course of 20 years. However, over the past decade, intense work on daily and seasonal rhythms in fruit flies, mustard plants, and hamsters and mice, has led to remarkable progress in understanding the phenomenology, as well as the molecular and genetic mechanisms underlying circadian rhythms and clocks. This book was developed to further this type of cooperation among scientists from all related disciplines. It brings together leading researchers working on photoperiodic timing of seasonal adaptations in plants, invertebrates, and vertebrates. Each of its three sections begins with an introduction by the section editor, and at the end of the book, the section editors present a synthesis of common themes in photoperiodism, as well as discuss similarities and differences in approaches to the study of photoperiodism, and future directions for research on photoperiodic time measurement.

Our knowledge of the circadian clock in plants has advancedconsiderably in recent years and we now have a clearer view of thebiochemical processes making up its mechanism. Recent work providesinsight into the central role played by the circadian system in theregulation of many aspects of metabolism. The multiple systemsinvolved in photoreception have been determined, leading to anunderstanding of how light entrains the internal biological clockto the natural cycle of day and night, and how this impacts on keyevents in the plant lifecycle, such as the photoperiodic regulationof flowering. This book provides a contemporary overview of endogenous plantrhythms for researchers and professionals in the plant sciences. Itwill also serve as a valuable source of reference for the widercircadian community.

(Chapters 11 to 14) summarise important features of the biological clock at the level of whole animal covering all vertebrate classes (fish to mammal). Chapters 15 and 16 are on long term (seasonal) rhythms in plants and higher vertebrates. Short term rhythms (ultradian rhythms), the significance of having a clock system in animals living in extreme (arctic) environments, and the diversity of circadian responses to melatonin, the key endocrine element involved in regulation of biological rhythms, have been discussed in Chapters 17 to 19. Finally, a chapter on sensitivity to light of the photoperiodic clock is added which, using vertebrate examples, illustrates the importance of wavelength and intensity of light on circadian and non-circadian functions. A well-known expert writes each chapter. When presenting information, the text provides consistent thematic coverage and feeling for the methods of investigation. Reference citation within the body of the text adequately reflects the literature as subject is developed. A chapter begins with an abstract that enables a reader to know at the first glance the important points covered in that chapter. The chapter concludes with a full citation of references included in the text, which could be useful for further reading. The book ends with a comprehensive subject index that may be useful for quick searches.

Rhythmic Phenomena in Plants, Second Edition focuses on the study of biological clocks in all kinds of plants, from unicellular algae to flowering trees. This book discusses the patterns of plant movement, parameters of rhythms and how to calculate them, and rhythms that match and do not match environmental periodicities. The mechanism of circadian timing, circadian rhythms in angiosperms, comparison between dinoflagellates and other rhythmic organisms, and semilunar and lunar rhythms are also elaborated. This publication likewise covers the measurement of day length in photoperiodism, circannian rhythms in plants, oscillations with short periods in leaves and roots, and streaming in a slime mold. This edition is valuable to biologists intending to contribute to the study of biological timing.

This second edition of a well-received book focuses on rhythmic behaviour in plants, which regulates all developmental and adaptive responses and can thus be regarded as quintessential to life itself. The chapters provide a timely update on recent advances in this field and comprehensively summarize the current state of knowledge concerning the molecular and physiological mechanisms behind circadian and ultradian oscillations in plants, their physiological implications for growth and development and adaptive responses to a dynamic environment. Written by a diverse group of leading researchers, the book will spark the interest of readers from many branches of science: from physicists and chemists wishing to learn about the multi-faceted rhythms in plants, to biologists and ecologists involved in the state-of-the-art modelling of complex rhythmic phenomena.

Photoperiodism is the response to the length of the day that enables living organisms to adapt to seasonal changes in their environment as well as latitudinal variation. As such, it is one of the most significant andcomplex aspects of the interaction between plants and their environment and is a major factor controlling their growth and development. As the new and powerful technologies of molecular genetics are brought to bear on photoperiodism, it becomes particularly important to place new work in the context of the considerable amount of physiological information which already exists on the subject. This innovative book will be of interest to a wide range of plant scientists, from those interested in fundamental plant physiology and molecular biology to agronomists and crop physiologists. Provides a self-sufficient account of all the important subjects and key literature references for photoperiodism Includes research of the last twenty years since the publication of the First Edition Includes details of molecular genetic techniques brought to bear on photoperiodism
