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.

Experts examine the mechanisms by which cells polarize, divide asymmetrically, and produce asymmetric structures, providing examples from bacteria, yeast, plants, invertebrates, and mammals. Discussion include the molecular basis of polarization, mechanisms, and more.

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.

Why does nature love symmetry? In Asymmetry, Developmental Stability and Evolution, M--oslash--;ller and Swaddle analyse the evolutionary implications of symmetry. They advance and explain their theory that asymmetry is related to genetic stability and fitness, and that symmetric individuals appear to have quantifiable and significant advantages over their asymmetric counterparts. When assessing potential mates or competitors, animals may be able to use symmetry as an honest indication of quality. This interdisciplinary book, with its associated Web-site, will be of interest to students and researchers in the fields of ecology, evolutionary biology, genetics, and animal behaviour. - ;Why does nature love symmetry?

Gene expression is the most fundamental level at which genotype gives rise to phenotype, which is an obvious, observable, and measurable trait. Phenotype is dependent on genetic makeup of the organism and influenced by environmental conditions. This book explores the significance, mechanism, function, characteristic, determination, and application of gene expression and phenotypic traits.

The field of developmental instability has generated a large amount of controversy recently, mostly because of fierce disagreement over the genetic basis of fluctuating asymmetry and its role in mate selection. This book is a timely and innovative critical evaluation of a burgeoning field. The book explores the premise that complex organismal, ecological and evolutionary processes can be understood as emergent properties of the "epigenetic machine," that is, the mechanisms fundamental to all organisms responsible for building and organizing phenotypes from information translated from DNA.
