Water Relations in Membrane Transport in Plants and Animals contains the presentations in a symposium dealing with Water Relations in Membranes in Plants and Animals, during the 27th Annual Fall Meeting of the American Physiological Society held at The University of Pennsylvania, 17-19 August 1976. The purpose of the symposium was to explore the common modes of water regulation in plants and animals. In these proceedings, the mechanisms employed to restrict water flow across plant and metazoan animal cells are described. Putative differences in mechanisms of water regulation retained by plant versus animal cells become inconsequential in the light of the numerous similarities: dependence upon bioelectric potentials maintained across cell membranes, energy dependence of uphill water movement, and solute coupling during water transport. The presentations can be organized into four. The first takes up specific mechanisms of water transport in plants. The second and third parts deal with specific mechanisms in invertebrates and vertebrates, respectively. The fourth part covers generalized mechanisms common to plants and animals.

Water Relations of Plants and Soils, successor to the seminal 1983 book by Paul Kramer, covers the entire field of water relations using current concepts and consistent terminology. Emphasis is on the interdependence of processes, including rate of water absorption, rate of transpiration, resistance to water flow into roots, soil factors affecting water availability. New trends in the field, such as the consideration of roots (rather than leaves) as the primary sensors of water stress, are examined in detail. Addresses the role of water in the whole range of plant activities Describes molecular mechanisms of water action in the context of whole plants Synthesizes recent scientific findings Relates current concepts to agriculture and ecology Provides a summary of methods

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.

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, Toronto (Canada); F. FLihr, JLilich (FRG); N. Higinbotham, Pullman, Wa. (USA); A. B. Hope, Adelaide (Australia); A. Lev, Leningrad (USSR); U. LLittge, Darmstadt (FRG); HW. NLirnberg, JLilich (FRG); E. A. C. MacRobb-ie, Cambridge (UK); H. Stieve, JLilich (FRG); M. Thellier, Rouen (France); K. Wagener, JLilich (FRG)) decided on a broad spectrum of topics including thermodynamics of transport processes, water relations, primary reactions of photosynthesis, as well as the more conventional aspects of membrane transport. They were thus, for instance, particularly concerned to bring advanced thermodynamical concepts to the attention of biologists and to show physical chemists what the more complex biological systems were like. We have taken considerable editorial liberty with the manuscripts submitted for this book, for we were very conscious of the necessity to make all papers understandable by as wide a circle of readers as possible.

The prospect of future climate change has stimulated research into the physiological responses of plants to stress. Water is a key factor controlling the distribution and abundance of plants. This book brings together contributions from a range of experts who have worked on the cavitation of water in the transport system.

Aquaporins are channel proteins that facilitate the diffusion of water and small uncharged solutes across cellular membranes. Plant aquaporins form a large family of highly divergent proteins that are involved in many different physiological processes. This book will summarize the recent advances regarding plant aquaporins, their phylogeny, structure, substrate specificity, mechanisms of regulation and roles in various important physiological processes related to the control of water flow and small solute distribution at the cell, tissue and plant level in an ever-changing environment.
