Book excerpt: Excerpt from The Carbohydrate Economy of Cacti The best evidence gained since the time of Sachs points to the conclusion that sugars are the first products which accumulate in the process of the photosynthesis of carbon compounds in the chlorophyllous cell. Thus, sugars may be considered the starting-point for the synthesis of the tre mendons number of substances found in living things, both vegetable and animal. What the sugar or mixture of sugars is which thus commands the center of attention in the metabolism of plants and of almost all living things is still a question of much dispute and uncertainty; nor does the solution of this problem seem possible until we have gained more knowledge of the transformations which the various sugars undergo in the cell, inde pendent Of photosynthesis. It has long been known that in the leaf, under circumstances, the polysaccharides are converted into the simpler sugars and vice versa, by what appears to be the shifting of an equilibrium by means of enzyme action. It is self-evident that a knowledge of these trans formations must be obtained before the problem of the first sugar syn thesized can be attacked. Not only in relation to the question of the immediate products of photo synthesis is the study of the carbohydrate equilibrium important, but also to the question of metabolism. In a very large number of plants, especially the higher ones, both the living and the lifeless matter consists in the main of material of carbohydrate nature. The lifeless matter forms the walls, vessels, supporting frame-work, and often a considerable amount of the reserve food-material. Those portions of the plant in which the manifesta tions of life appear, as for instance the chromatin of the nucleus and the protoplasm itself, contain a considerable quantity of carbohydrates, the life less being formed from the living and the living drawing upon the lifeless for support. It is, however, a question whether the difference between the living and lifeless is essentially one of chemical constitution. The idea that the living substance or protoplasm is a complex compound of more or less definite chemical constitution no longer seems tenable. Protoplasm, a mixture of so many different substances, undoubtedly varies in composition in different organisms. It is in all probability the study of the physical and chemical properties of protoplasm as a colloidal mixture (such proper ties as imbibition of water, electrical charges, and surface phenomena) which will yield the most illuminating results.

Book excerpt: "There is nothing in the world like this book. It should be in every library and on the bookshelves of all those interested in cacti. The book will be an important resource for plant physiology, agronomy, and horticulture classes at both the undergraduate and graduate level."—Bruce Smith, Brigham Young University "Cacti: Biology and Uses is a landmark publication of one of the world's most unique group of plants. Park Nobel, a leading authority on succulent plants, has assembled a collection of contributions that spans a wide range of issues extending from basic systematics, anatomy, physiology and ecology to considerations of conservation and human uses of this diverse group of plants. This nicely-produced and well-illustrated volume provides a resource that will be of great use to a wide range of scientists, practitioners, and enthusiasts of this plant group."—Harold Mooney, Paul S. Achilles Professor of Environmental Biology, Stanford University

Download or read book Crassulacean Acid Metabolism written by Klaus Winter and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crassulacean acid metabolism (CAM) represents one of the best-studied metabolic examples of an ecological adaptation to environmental stress. Well over 5 % of all vascular plant species engage in this water-conserving photosynthetic pathway. Intensified research activities over the last 10 years have led to major advances in understanding the biology of CAM plants. New areas of research reviewed in detail in this book include regulation of gene expression and the molecular basis of CAM, the ecophysiology of CAM plants from tropical environments, the productivity of agronomically important cacti and agaves, the ecophysiology of CAM in submerged aquatic plants, and the taxonomic diversity and evolutionary origins of CAM.
Download or read book Phytochemical Methods written by Jeffrey B. Harborne and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: While there are many books available on methods of organic and biochemical analysis, the majority are either primarily concerned with the application of a particular technique (e.g. paper chromatography) or have been written for an audience of chemists or for biochemists work ing mainly with animaltissues. Thus, no simple guide to modern metho ds of plant analysis exists and the purpose of the present volume is to fill this gap. It is primarily intended for students in the plant sciences, who have a botanical or a general biological background. It should also be of value to students in biochemistry, pharmacognosy, food science and 'natural products' organic chemistry. Most books on chromatography, while admirably covering the needs of research workers, tend to overwhelm the student with long lists of solvent systems and spray reagents that can be applied to each class of organic constituent. The intention here is to simplify the situation by listing only a few specially recommended techniques that have wide currency in phytochemical laboratories. Sufficient details are provided to allow the student to use the techniques for themselves and most sections contain some introductory practical experiments which can be used in classwork.

This book was released on 2001 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Opuntias are multipurpose plants that are increasingly being used in agricultural systems in arid and semi-arid areas. Due to its high water-use efficiency, it is particularly useful as forage in times of drought and in areas where few other crops can grow, and it is now considered a key component for the productivity and sustainability of these regions. This publication presents current scientific and practical information on the use of the cactus Opuntia as forage for livestock.
