Available in PDF, EPUB and Kindle. Book excerpt: TO THE SECOND EDITION When preparing the manuscript for the original edition of this book we were only partly aware of the pace at which the field of membrane transport was developing and at which new ideas as well as new techniques would be applied to it. The fact is that some of the chapters are now outdated (e. g. , the one on the molecular aspects of transport) and many others require revision in the light of new information that has appeared in the past five years. However, it is also true that we overemphasized in the first edition certain points that now appear less important and underestimated the impact of certain others that have since assumed a position among the most forcefully discussed topics of membrane research. In making amends, it was thus thought useful to include the discussion of these latter problems both in the theoretical and in the comparative sections and, on the other hand, to omit some of the less topical subjects. There was a different reason for rewriting the section on kidney and for dropping the section on mito chondria. The help of an expert nephrologist was enlisted for improving chapter 24, while it was decided that mitochondria represent a special field both conceptually (being only subcellular particles) and methodologically (more indirect estimation techniques being involved than with whole cells or tissues) and that more adequate information can be found in treatises specializing in work with mitochondria.

Available in PDF, EPUB and Kindle. Book excerpt: As plant physiology increased steadily in the latter half of the 19th century, problems of absorption and transport of water and of mineral nutrients and problems of the passage of metabolites from one cell to another were investigated, especially in Germany. JUSTUS VON LIEBIG, who was born in Darmstadt in 1803, founded agricultural chemistry and developed the techniques of mineral nutrition in agricul ture during the 70 years of his life. The discovery of plasmolysis by NAGEL! (1851), the investigation of permeability problems of artificial membranes by TRAUBE (1867) and the classical work on osmosis by PFEFFER (1877) laid the foundations for our understanding of soluble substances and osmosis in cell growth and cell mechanisms. Since living membranes were responsible for controlling both water movement and the substances in solution, "permeability" became a major topic for investigation and speculation. The problems then discussed under that heading included passive permeation by diffusion, Donnan equilibrium adjustments, active transport processes and antagonism between ions. In that era, when organelle isolation by differential centrifugation was unknown and the electron microscope had not been invented, the number of cell membranes, their thickness and their composition, were matters for conjecture. The nature of cell surface membranes was deduced with remarkable accuracy from the reactions of cells to substances in solution. In 1895, OVERTON, in U. S. A. , published the hypothesis that membranes were probably lipid in nature because of the greater penetration by substances with higher fat solubility.

Available in PDF, EPUB and Kindle. Book excerpt: In February, 1974, an 'International Workshop on Membrane Transport in Plants' was held at the Nuclear Research Centre, JLiI ich, West Germany. More than two hundred and fifty people, from fourteen countries, took part in this highly successful meeting. A somewhat similar meeting took place in Liverpool, England, two years ago and it became clear there that progress in the field of membrane transport in plants was now so marked that a second, and wider, meeting in Germany was more than fully justified. The members of our pro gramme committee (U. Zimmermann, Chairman, JLilich (FRG); J. Dainty,

Available in PDF, EPUB and Kindle. Book excerpt: Commentaries in Plant Science, Volume 2 is a collection of papers that reviews developments in the pure and applied science of plants. One paper discusses the role of supercooling in the winter survival mechanism of and ecological distribution of many plant communities. Another paper evaluates the Cholodny-Went theory of shoot geotropism that there is strong evidence in auxin redistribution occurring in a rapid manner to cause geotropic curvature. The magnitude of auxin redistribution is too rare to cause differential growth. Some insect pests have specific nutritional requirements and well-developed mechanisms for selecting their plant host. One paper enumerates the benefits of using insect-resistant host plant varieties, such as the non-incurrence of extra costs, these are environmentally safe, and are compatible with most other methods of pest control. Another paper discusses the nature and possible genetic manipulation of a complex bacteria, the actinomycetes, as well as its role as antibiotic producer. Another paper examines the nature of seed storage proteins and of the cellular processes that are related in their synthesis and deposition especially in cereals and legume. This collection is suitable for botanists, genecologists, taxonomists, biologists, and investigators whose works involve cell membrane research.
