Available in PDF, EPUB and Kindle. Book excerpt: "Plant collections, field and herbarium studies were used to evaluate classifications of Impatiens. Accepted interpretations of the perianth are questioned; and a program of developmental studies on several categories of inflorescences proposed. The fruit has been incorrectly described. It is of two types, differing in manner of dehiscence. Chromosome numbers are an inadequate taxonomic character because of parallel cytoevolution. Karyotypes were prepared, but it was found that homologues were not distinguishable. A technique for Hy-banding was developed, and homologues in plants of I. leschenaultii Wall. identified. It is proposed that Hy-banding can identify marker chromosomes which will be a more efficient character than complete karyotypes. The classifications of Impatiens are discussed, and it is concluded that one founded on flower-pollinator relationships is the best, although convergence is a problem. The genera of the Balsaminaceae are reviewed. It is concluded that these show only slight deviations from Impatiens, and are rejected." --

Book excerpt: This fourth edition of Plant Systematics is completely revised and updated. It incorporates the updated International Code of Nomenclature for Algae, Fungi and Plants (Shenzhen Code, 2018), the new version of PhyloCode (Beta version of Phylocode 5, 2014), APweb version 14 (September, 2018), revised Angiosperm Phylogeny Group classification (APG IV, 2016), new Pteridophyte Phylogeny Group Classification (PPG I, 2016), besides the updates since the publication of third edition. The book is a blend of classical fundamental aspects and recent developments, especially in the field of molecular systematics, cladistics and computer identification. Special attention has been given to information on botanical nomenclature, identification, molecular systematics and phylogeny of angiosperms. The complicated concepts of phylogeny, taxometrics and cladistics have been explained with a view to providing a comparison between these diverse but interactive fields of study. An attempt has been made to build upon a common example when exploring different methods, especially in procedures of identification, taxometrics and cladistics. The major systems of classification are evaluated critically. Discussion on major families of Pteridophytes, Gymnosperms and Angiosperms, especially those of major phylogenetic interest, form a major portion of this edition. The ebook includes nearly 500 color photographs set out in 36 pages covering plants from different parts of the world. In addition, 305 black & white illustrations have been included to provide a better understanding of the plants covered in the book.

This book was released on 2012-12-06 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: For several decades botanists have been impressed by the discovery that the distribution of secondary plant substances follows the general lines of plant relationships. However, it soon became clear that little was to be gained from the study of individual compounds and their natural distribu tion. Therefore, more comprehensive studies were attempt ed in which the secondary chemistry of a major plant group was carefully studied and evaluated in the broader context of comparative phytochemistry. Holger Erdtman's admir able work on Coniferae is the foremost example of this kind. Since then, there has been an upswing in the study of the biosynthesis of secondary plant substances and it has become quite customary to make use of biosynthetic knowledge in interpreting chemosystematic evidence. More over, since taxonomists have insisted that use be made of all potentially available evidence for building classifications, it has been claimed that chemosystematics too should con sider the whole array of constituents present in a major taxon. However, in practice it has proved difficult to utilize fully the potential of natural product chemistry and biosynthetic studies for plant systematics and evolution, because bota nists found themselves rather disorientated by the scattered, often hardly accessible chemical literature and the fact that the chemical evidence was difficult for them to evaluate! Although the pioneering work of E. C.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Systematics, Third Edition, has made substantial contributions to plant systematics courses at the upper-undergraduate and first year graduate level, with the first edition winning The New York Botanical Garden's Henry Allan Gleason Award for outstanding recent publication in plant taxonomy, plant ecology or plant geography. This third edition continues to provide the basis for teaching an introduction to the morphology, evolution and classification of land plants. A foundation of the approach, methods, research goals, evidence and terminology of plant systematics are presented, along with the most recent knowledge of evolutionary relationships of plants and practical information vital to the field. In this new edition, the author includes greatly expanded treatments on families of flowering plants, as well as tropical trees (all with full-color plates), and an updated explanation of maximum likelihood and Bayesian inference algorithms. Chapters on morphology and plant nomenclature have also been enhanced with new material. Covers research developments in plant molecular biology Features clear, detailed cladograms, drawings and photos Includes major revisions to chapters on phylogenetic systematics and plant morphology

Download or read book Molecular Systematics of Plants II written by Pamela Soltis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the five years since the publication of Molecular Systematics of Plants, the field of molecular systematics has advanced at an astonishing pace. This period has been marked by a volume of new empirical data and advances in theoretical and analytical issues related to DNA. Comparative DNA sequencing, facilitated by the amplification of DNA via the polymerase chain reaction (PCR), has become the tool of choice for molecular systematics. As a result, large portions of the Molecular Systematics of Plants have become outdated. Molecular Systematics of Plants II summarizes these recent achievements in plant molecular systematics. Like its predecessor, this completely revised work illustrates the potential of DNA markers for addressing a wide variety of phylogenetic and evolutionary questions. The volume provides guidance in choosing appropriate techniques, as well as appropriate genes for sequencing, for given levels of systematic inquiry. More than a review of techniques and previous work, Molecular Systematics of Plants II provides a stimulus for developing future research in this rapidly evolving field. Molecular Systematics of Plants II is not only written for systematists (faculty, graduate students, and researchers), but also for evolutionary biologists, botanists, and paleobotanists interested in reviewing current theory and practice in plant molecular systematics.

Available in PDF, EPUB and Kindle. Book excerpt: Modern angiosperm taxonomy or systematics provides a strong foundation for the progress of biological sciences as it incorporates studies on biosystematics, chemical and serological evidences, numerical taxonomy, cytogenetical and ecological evidences and many others. This book accounts for information on classical and fundamental aspects of taxonomy as well as its recent developments. Special attention has been paid to the chapters on origin of Angiosperms, Theory of Evolution and Evolutionary trends in Angiosperm Flowers. The International Code of Botanical Nomenclature, Important herbaria, Techniques for the preparation, storage and study of herbarium specimens, Botanical gardens, and Taxonomic literature are discussed in detail and includes the study of some selected families belonging to 21 orders. For each family, general features and evidence from anatomical, embryological, chromosome numbers and phytochemical data have been added and evolutionary trends discussed. Attention has also been drawn to economic importance and geographical distribution of these families. Illustrations for some members of these families have also been added.
