The Chemotaxonomy Of Plants

Taxonomy is the theory and practice of classification, and chemotaxonomy incorporates the principles and procedures involved in the use of chemical evidence for classificatory purposes. Chemical Systematics is the study of the chemical variation in a diversity of organisms, and of their relationships. This book does not aim to give accounts of the systematics of any group of plants but rather to introduce and illustrate the ways in which chemical data may be used with profit to taxonomists.

Chemical Plant Taxonomy focuses on the classification of plants based on their chemical composition. Composed of contributions of authors, the text first considers the methods of plant taxonomy. Folk taxonomy; Linnaean and post-Linnaean taxonomy; Darwin and ""Evolutionary Taxonomy""; and the development of taxonomic practice are considered. The book continues with discussions on the theoretical and practical aspects of the ""species"" concepts and an outline of the history of chemical taxonomy. The selection also looks at the qualities of chemotaxonomy, the usefulness of chemistry in plant taxonomy, biosynthetic pathways, and the factors affecting the production of secondary plant products. The text discusses the distribution of alkanes. The isolation and characterization of alkanes; taxonomic applications of alkanes; biogenesis of alkanes; and fossil alkanes are discussed. The selection highlights the chemical taxonomy of acetylenic compounds, the distribution of fatty acids in plant lipids, distribution of aliphatic polyols, cyclitols, plant glycosides, and alkaloids. The text is a good source of information for readers wanting to study the taxonomy of chemical plants.

Plant classifications are based on morphological characters and it is difficult, particularly in small plants and grasses, to identify these below generic level on the basis of these characters using a dissecting microscope. Plant species have intra- and inter-specific variation in secondary metabolites which can be utilized as marker compounds for identification and classification of plants. Secondary metabolites are produced as a result of primary metabolism and the production of these compounds not only involves several genes but also it is an energy dependent process. Hence these products cannot be considered as insignificant for the plant and the environment. Modern tools of molecular biology and secondary metabolites present in them can definitively decide about classification of plants. Absence of correct identification of plant is associated to many problems of resource utilization. Due to wide availability of these tools, interest has revived in systematics and correct classification of plants based on these parameters for their sustainable utilization and resource management. The purpose of this book is to assess the potential of phytochemical and molecular tools in the systematic and classification of plants. The topics covered include species concept, barcoding and phylogenetic analysis, chemotaxonomy use of polyketides, carotenes, cuticular wax, volatile oils, biodiversity of corals, metazoans, Ruta and Echinocereus. It provides comprehensive and broad subject-based reviews, useful for students, teachers, researchers, and all others interested in the field. The field has been kept wide and general to accommodate the wide-ranging topics. This book will be useful to agriculturists, chemists, botanists, industrialists, and those involved in planning of crop plants.

This brand new Annual Plant Reviews volume is the second edition of the highly successful and well-received Annual Plant Reviews, Volume 2. This exciting new volume provides an up-to-date survey of the biochemistry and physiology of plant secondary metabolism. The volume commences with an overview of the biochemistry, physiology and function of secondary metabolism, followed by detailed reviews of the major groups of secondary metabolites: alkaloids and betalains, cyanogenic glucosides, glucosinolates and nonprotein amino acids, phenyl propanoids and related phenolics, terpenoids, cardiac glycosides and saponins. A final chapter discusses the evolution of secondary metabolism. This carefully compiled new edition brings together chapters from some of the world's leading experts in plant secondary metabolism. Completely revised and brought right up to date with much new information, this volume is an essential purchase for advanced students, researchers and professionals in biochemistry, physiology, molecular biology, genetics, plant sciences, agriculture, medicine, pharmacology and pharmacy, working in the academic and industrial sectors, including those working in the pesticide and pharmaceutical industries. Libraries in all universities and research establishments where these subjects are studied and taught will need copies of this excellent volume on their shelves. A companion volume Annual Plant Reviews Volume 39, Functions and Biotechnology of Plant Secondary Metabolites, Second Edition, Edited by M. Wink, is also available.
