Plants exhibit forms of asymmetry analogous to "handedness" in bilaterally symmetrical animals. This book explores the evolutionary significance and development of asymmetry. Examples of genetic control include the direction of tendril or stem coiling of many climbing plants; the so-called spiral phyllotaxy and floral taxy; and contorted petal arrangement is another kind of left- right symmetry in plants; the direction of contortion is fixed in some but not in other plants. The book will underscore tha all phenomena related to handedness start during embryogenesis itself, with the occurrence of embryo rotation. Key selling features: First consolidated book on Plant Handedness Relates handedness, asymmetry and chirality to the evolution of different organizational levels in plant biology Emphasizes handedness as a vital governing force in plant functional evolution Provides a new perspective, hitherto ignored, into plant developemtn and evolution Describes how an age-old phenomenon can give scope for investigation from a very modern interdisciplinary approach

The book deals with biological, mathematical, descriptive, causal and systemic phyllotaxis. It aims at reflecting the widest possible range of ideas and research closely related to phyllotaxis and contains 30 well illustrated chapters.The book has three parts of equal importance. The first two parts concern data collecting, pattern recognition and pattern generation to which students of phyllotaxis are well accustomed. The third part is devoted to the problem of origins of phyllotactic patterns, giving the field of phyllotaxis the universality it requires to be fully understood.Phyllotaxis-like patterns are found in places where genes are not necessarily present. Part III concerns general comparative morphology, homologies with phyllotactic patterns, and recent trends on evolution that can help to understand phyllotaxis.The distinguished researchers who accepted to participate in the production of this book, strongly contributed to the field of phyllotaxis in the past and have devoted a lot of their time to the fascinating subject coming up with most valuable findings, or are newcomers with original ideas that may be very relevant for the future of the field. The book summarizes and updates their contributions, and promotes new avenues in the treatment of phyllotaxis.This book on mathematical and biological phyllotaxis is the first collective book ever. A landmark in the history of phyllotaxis.

The establishment of polarity is a fundamental feature in eukaryotic development. Polarity in Plants provides an account of current research into the mechanisms by which polarity is generated at the level of the cell, organ and organism in plants, drawing especially on recent work with model organisms. The emphasis is on the use of the techniques of molecular genetics to dissect molecular mechanisms. This is the first volume to bring together the diverse aspects of polarity in plant development.

The value of the fluctuating asymmetry shows the relative ineffectiveness of organismic control systems developmental processes. Assessment of the environmental quality is now a very promising approach for the integral characteristic of living organisms. Stability of development is characterized by the level of fluctuating asymmetry in morphological structures. In this monograph the morphogeometric method was applied to assess the FA leaf plate woody plants (birch, oak, linden and maple). Results of the developmental stability monitoring in plant ecosystems were reported on the example of one of the region in Russia.

This book gathers concepts of information across diverse fields –physics, electrical engineering and computational science – surveying current theories, discussing underlying notions of symmetry, and showing how the capacity of a system to distinguish itself relates to information. The author develops a formal methodology using group theory, leading to the application of Burnside's Lemma to count distinguishable states. This provides a tool to quantify complexity and information capacity in any physical system.

In recent years, there has been a growing interest in the problem of asymmetry of bilateral traits in plants. Three types of bilateral asymmetry are found in the leaf blade, of interest to ecologists and evolutionists. A brief review of the methods used in testing bilateral asymmetry and developmental stability discusses their role in the development of homeostasis and ontogenesis. Intra- and interspecific differences are considered on the example of woody plants under the influence of factors influencing the expression of bilaterally symmetry. The influence of stress on the manifestation of asymmetric traits is considered. Apparently, the climate and topography of the area play a more important role, determining the plastic and fluctuating variability. The relationship of plasticity, evolutionary canalization, and development stability is considered on the example of woody and cultivated plants. Plasticity and fluctuation variability are in a relationship coordinated by climatic conditions, primarily lighting and temperature. This, in turn, determines the mechanisms of gene regulatory networks. Thus, phenogenetics, which studies the patterns and mechanisms of gene expression and ontogenesis, is based on the data from field botanical studies of plant shape and asymmetry. Epigenetic and population studies of phenotypic variations play a role in standardizing and finding suitable plant species and varieties.

From the New York Times-bestselling author of The Secret World of Weather and The Lost Art of Reading Nature’s Signs, learn to tap into nature and notice the hidden clues all around you Before GPS, before the compass, and even before cartography, humankind was navigating. Now this singular guide helps us rediscover what our ancestors long understood—that a windswept tree, the depth of a puddle, or a trill of birdsong can help us find our way, if we know what to look and listen for. Adventurer and navigation expert Tristan Gooley unlocks the directional clues hidden in the sun, moon, stars, clouds, weather patterns, lengthening shadows, changing tides, plant growth, and the habits of wildlife. Rich with navigational anecdotes collected across ages, continents, and cultures, The Natural Navigator will help keep you on course and open your eyes to the wonders, large and small, of the natural world.

This volume emphasizes the involvement of all facets of biology in the analysis of environmentally controlled movement responses. This includes biophysics, biochemistry, molecular biology and as an integral part of any approach to a closer understanding, physiology. The initial euphoria about molecular biology as the final solution for any problem has dwindled and the field agrees now that only the combined efforts of all facets of biology will at some day answer the question posed more than hundred years ago: "How can plants see?". One conclusion can be drawn from the current knowledge as summarized in this volume. The answer will most likely not be the same for all systems.
