Book excerpt: "The book strikes a balance between classical fundamental information and the recent developments in plant systematics. Special attention has been devoted to the information on botanical nomenclature, identification and phylogeny of angiosperms with numerous relevant examples and detailed explanation of the important nomenclatural problems. An attempt has been made to present a continuity between orthodox and contemporary identification methods by working on a common example. The methods of identification using computers have been further explored to help better online identification. The chapter on cladistic methods has been totally revised, and molecular systematics discussed in considerable detail."--Jacket.

Download or read book Caryophyllales written by H.D. Behnke and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Caryophyllales are one of the few higher taxa of the flowering plants ofwhich the size and delimitation against other taxa is undisputed. However, their derivation from other taxa and the evolution of families within this order in unsettled. "Systematics and Evolution of the Caryophyllales" reviews the important characters of this taxon emphasizing their contribution and influence towards a new proposal for both the putative origin of the order and the classification of its families. New results in molecular genetics, phytochemistry, ultrastructure, and morphology are provided and discussed in relation to both the classical and molecular systematics of the order. In addition, characters like betalains and sieve-element plastids, which have played a major role in shaping the size of the order, and others like DNA-data or flower morphologythat can be useful to discuss the position of the Caryophyllales within higher plants are critically evaluated.

Download or read book Ethnopharmacology of Medicinal Plants written by Christophe Wiart and published by Springer Science & Business Media. This book was released on 2007-11-04 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1860, Oliver Wendell Holmes pointedly expressed himself to the Massachusetts Medical Society: “I firmly believe that if the whole Material Medica, as now used, could be sunk to the bottom of the sea, it would be all the better for mankind, and all the worst for the fishes.” Should one think the same about the current approach in drug discovery from plants? Probably yes. Despite the spending of billions of US dollars, and three decades of efforts, high-throughput screenings have only allowed the discovery of a couple of drugs. One could have reasonably expected the discovery of an arsenal of drugs from the millions of plant extracts randomly tested, but “hits” can be inactive in vitro or too toxic, some molecules need to be metabolized first to be active, and false-positive and false-negative results are common. The bitter truth is that the robotic approach in discovering drugs from plants has proven, to date, its inability to excavate the hundreds of molecules that will contribute to the health progress of Man. However, one can reasonably see that the last patches of primary rainforest on earth hold still hundreds of spectacularly active drugs that await discovery.

Download or read book Measuring Roots written by Stefano Mancuso and published by Springer Science & Business Media. This book was released on 2011-10-26 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Roots represent half of the plant body – and arguably the more interesting half. Despite its obvious importance for the whole plant, until recently our knowledge of the root apparatus was very limited, mostly due to the inadequacy of the techniques available. Recent advances in the visualization and measurement of roots have resulted in significant progress in our understanding of root architecture, growth and behaviour. In this book international experts highlight the most advanced techniques, both lab and field methods, and discuss them in detail. Measuring Roots combines academic and practical aspects of this topic, making it a universal handbook for all researchers and others interested in root-measuring methods.

Download or read book Dynamic Aspects Of Natural Products Chemistry written by Takeshi Ogura and published by CRC Press. This book was released on 1997-11-21 with total page 694 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface: Natural products chemistry has a long history, and could be regarded as having its roots in the use of many kinds of herbal mixtures as crude drugs in traditional medicine. Systems of traditional medicine have been practiced in China and Japan for thousands of years, and virtually all regions of the world have used natural materials to treat human disease. It was clear that many plants, herbs, etc. contain components with powerful biological activities. The dawn of modern natural products chemistry began with the isolation of the active component, morphine, from opium. Subsequently, various alkaloids were isolated from medicinal plants and employed clinically. The discovery and the development of penicillin as a microbial metabolite opened up the era of antibiotics, which have saved countless lives in the past half century or so. The isolation and synthesis of steroid hormones resulted in the development of new concepts in molecular stereochemistry and organic synthetic techniques, as did the discovery of bioactive lipids such as prostaglandins and leukatrienes, bioactive peptides such as enkephalins and endetherines, and oligosaccharides, including glycoproteins. Further, the discovery of plant hormones has led to great strides in plant biotechnology, including plant tissue cultures, and derivatives of insect hormones and pheromones are now used as pesticides. Thus, applications of natural products chemistry have become all-pervasive in modern society. Apart from the extensive practical applications of natural products and their derivatives, natural products chemistry has played a central role in the development of modern organic chemistry as a result of its focus on structural and synthetic studies of often highly complex and inaccessible molecules. Biosynthetic studies have also attracted much attention, aiming to answer the questions of why and how such a large number and variety of compounds are synthesised by organisms. Researchers in the field of biosynthesis first focused on elucidation of the pathways of secondary metabolism, and then on the mechanisms, of the enzymes catalyzing the biosynthetic reactions. This was an extremely difficult task, because rather large amounts of enzymes are required for the investigation of reaction mechanisms and the enzyme proteins are often unstable and not easy to purify. However, in recent years the development of molecular biology has made gene and protein engineering rather routine. Thus, studies of mechanistic enzymology can now be conducted with cloned and overexpressed enzyme proteins. It has been shown that the enzymes responsible for the biosynthesis of antibiotics in Streptomyces spp. are encoded in gene clusters. Further, cloning and functional analysis of the genes associated with flavonoid biosynthesis should soon cast light on the interesting question of why flavonoids are ubiquitously present in plant leaves. Life is maintained not only by large molecules such as proteins and nucleic acids, but also by many small molecules which have essential and diverse roles in the physiology of living organisms. Such compounds often have highly specific interactions with target receptors, but the mechanisms involved largely remain to be explored. Current methodology means that this task can be addressed, and this in turn should lead to a host of new applications for natural products and their derivatives. The key may be an interdisciplinary approach taking account of both biological function and molecular behaviour based on precise structure recognition. As we increasingly understand the mechanisms of molecular recognition that operate in nature, many possibilities should open up for artificial control or modification of biological functions, as well as new challenges for synthetic organic chemists. Our intention in this book is to focus on such dynamic aspects of natural products chemistry. By dealing in detail with representative topics to which the most modern techniques of research have been applied, we hope to emphasize the value of combining traditional approaches to natural products chemists with current biochemical and molecular-biological ideas. Each chapter provides sufficient background information and experimental detail to make the subject accessible to non-specialists. It is our hope that these examples of recent progress in key areas of natural products chemistry will stimulate work in related topics by illustrating the power of a modern interdisciplinary approach to the subject.
