Available in PDF, EPUB and Kindle. Book excerpt: T. J. MABRY and G. W AGENITZ The half-day symposium on "Multidisciplinary approaches to the systematics of Compositae", held as part of the XIV International Botanical Congress in Berlin, on July 26, 1987, was designed to complement the University of Reading Compositae Conference (1975). The latter had yielded two impressive and thorough volumes on "The biology and chemistry of the Compositae", which were edited by HEYWOOD, HARBORNE & TURNER (1977). The 1987 Berlin Symposium did not attempt to update the information from the earlier conference but instead focussed on selected new methods for investigating the systematics of the family as well as a few examples of new systematic approaches with classical methods. From mapping chloroplast DNA restriction sites JANSEN, PALMER, and MI CHAELS reported the astonishing fact that, with the exception of one group (the subtribe Barnadesiinae of the tribe Mutisieae), all investigated other members of Compositae exhibit a characteristic inversion in their chloroplast DNA, suggesting that the inversion occurred early in the evolution of the family and that at least its major part is monophyletic. Within those groups with the inverted segment, chloroplast DNA also suggests that most of the conventionally recognized tribes are also monophyletic. This lends high credit to our predecessors who laid the foundations for the taxonomic system of the Compositae. These chloroplast DNA studies have already been published and are not included here (JANSEN & PALMER 1987, 1988).

Available in PDF, EPUB and Kindle. Book excerpt: "This spectacular book does full justice to the Compositae (Asteraceae), the largest and most successful flowering plant family with some 1700 genera and 24,000 species. It is an indispensable reference, providing the most up-to-date hypotheses of phylogenetic relationships in the family based on molecular and morphological characters, along with the corresponding subfamilial and tribal classification. The 2009 work not only integrates the extensive molecular phylogenetic analyses conducted in the last 25 years, but also uses these to produce a metatree for about 900 taxa of Compositae. The book contains 44 chapters, contributed by 80 authors, covering the history, economic importance, character variation, and systematic and phylogenetic diversity of the family. The emphasis of this work is phylogenetic; its chapters provide a detailed, current, and thoroughly documented presentation of the major (and not so major) clades in the family, citing some 2632 references. Like the Compositae, the book is massive, diverse, and fascinating. It is beautifully illustrated, with 170 figures, and an additional 108 cladograms (all consistently color-coded, based on the geographic range of the included taxa); within these figures are displayed 443 color photographs, clearly demonstrating the amazing array of floral and vegetative form expressed by members of the clade." --NHBS Environment Bookstore.

Download or read book Style Diversity in Asteraceae Morphology Anatomy Phylogeny and Function written by Claudia Erbar and published by . This book was released on 2021-01-07 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is the most comprehensive and up-to-date overview of style morphology and anatomy of the plant family Asteraceae (or Compositae; asters, daisies, sunflowers), using the most current generalized phylogenetic tree based on molecular data as reference. The Asteraceae are the largest plant family (one out of about every 10 species of the flowering plants belongs to this family); they include about 25,000 currently accepted species in 14 subfamilies and 44 tribes. The authors distinguish 49 style types in the Asteraceae. The style characters are compared with other features that indicate a systematic relationship. The style of an individual flower of the Asteraceae is one of the most important floral organs in two respects: Firstly, the characteristics of the style contribute to the systematics of the family, secondly, the different forms of styles are of utmost importance to secondary pollen presentation. The latter allows for optimizing pollination by pollen portioning, a widespread phenomenon in angiosperms. Combining both morphology and function, the style types represent eight possibilities of secondary pollen presentation, which can be subsumed into four main functional categories. Style characteristics and mechanisms of secondary pollen presentation are plotted in up-to-date phylogenetic trees to illustrate and discuss possible evolutionary trends in the Asteraceae. Evaluating style characters and the position of the style tip within the anther tube shortly before anthesis now allows; in most cases; to easily predict the mechanism of secondary pollen presentation. The different style types are exquisitely illustrated by high quality greyscale and colour images and numerous line drawings. The study is complemented by extensive bibliography, a table of the specimens studied (species, collection, etc.) and an index. This style atlas is useful not only to botanists (especially synantherologists) and entomologists, but addresses a wider audience interested more generally in the systematics of flowering plants and the evolution of floral characters and function.

This book was released on 2007-05-08 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: P. T. N. SPENCER-PHILLIPS Co-ordinator, Downy Mildew Working Group of the International Society for Plant Pathology University of the West of England, Coldharbour Lane, Bristol BS16 1QY, UK Email: [email protected] It is a very great privilege to write the preface to the first specialist book on downy mildews since the major work edited by D. M. Spencer in 1981. The idea for the present publication arose from the Downy Mildew Workshop at the International Congress of Plant Pathology (ICPP) held in Edinburgh in August 1998. Our intention was to invite reviews on selected aspects of downy mildew biology from international authorities, and link these to a series of related short contributions reporting new data. No attempt has been made to cover the breadth of downy mildew research, but we hope that further topics will be included in future volumes, so that this becomes the first of a series following the five year ICPP cycle.

Download or read book Artemisia annua Pharmacology and Biotechnology written by Tariq Aftab and published by Springer Science & Business Media. This book was released on 2013-11-26 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artemisinin, a sesquiterpene lactone originally extracted from the medicinal plant Artemisia annua L., is an effective antimalarial agent, particularly for multi-drug resistant and cerebral malaria. However, the concentration of artemisinin in the plant is very low. Because the chemical synthesis of artemisinin is complicated and not economically feasible in view of the poor yield of the drug, the intact plant remains the only viable source of artemisinin production. Therefore, it is necessary to increase the concentration of artemisinin in A. annua to reduce the cost of artemisinin based antimalarial drugs. Plant scientists have focused their efforts on A. annua for a higher artemisinin crop yield. With the present volume, we are bringing together the research which is being done on this plant throughout the world and future possibilities for scientists and researchers who want to work on it.
Download or read book Flora of the Gran Desierto and R o Colorado Delta written by Richard Stephen Felger and published by University of Arizona Press. This book was released on 2023-02-07 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Pinacate lava fields and expansive dunes to the shores of the Gulf of California, the Gran Desierto is one of the hottest and driest places in the Western Hemisphere. Yet this region in the state of Sonora in northwestern Mexico embraces a remarkable number of habitats with a fascinating and surprisingly rich flora. This is the heart of the Sonoran Desert, still in a largely primordial state, in juxtaposition with the ravished wetlands of the once great Río Colorado. Flora of the Gran Desierto is the culmination of more than twenty-five years of research in this magnificent desert and delta by botanist Richard Felger. This comprehensive floristic study of more than 565 species of vascular plants features original diagnostic descriptions and innovative identification keys to the families, genera, and species. Particular attention has been devoted to taxa that are poorly known. Even weeds and their histories are treated in detail. Hundreds of illustrations by such eminent botanical artists as Lucretia Brezeale Hamilton, Matt Johnson, and Bobbi Angell will aid in the identification of plants. Common names of plants are given in English, Spanish, and O'odham. While emphasizing scientific accuracy, the book is written in an accessible style. Felger's observations and knowledge of plant ecology, geographic distribution, evolution, ethnobotany, plant variation and special adaptations, and the history of the region provides botanists, naturalists, ecologists, conservationists, and anyone else celebrating the desert with readable, interesting, and important information. With two of Mexico's newest biosphere reserves—the Pinacate and the Upper Gulf of California—this region is a keystone for desert conservation efforts. Its location linking vast preserves to the north makes this book especially useful for anyone interested in borderland studies and the Sonoran Desert. Flora of the Gran Desierto represents a most creative, definitive, and enthusiastic treatment of Sonoran Desert plant life and is highly relevant to ecological restoration in deserts and wetlands in arid places worldwide.
Download or read book Flavonoids of the Sunflower Family Asteraceae written by Bruce A. Bohm and published by Springer Science & Business Media. This book was released on 2013-11-27 with total page 836 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flavonoids are secondary plant products that have previously been shown to be helpful in determining relationships among plant groups. This work presents comprehensively the occurrence, patterns of variation, and systematic and evolutionary importance of flavonoids in the sunflower family (Asteraceae), the largest family of flowering plants (23,000 species). It gathers together the more than 2500 reports of flavonoids in Asteraceae published between 1950 to the present and interprets these data in context of new taxonomic (especially generic) alignments. The authors discuss flavonoid patterns with reference to modern phylogenetic studies based on morphology and DNA data. This book provides, therefore, the most exhaustive synthesis and evaluation of the systematic and evolutionary import of flavonoids ever accomplished for any large family of angiosperms.
