Modern Methods of Plant Analysis When the handbook Modern Methods of Plant Analysis was first introduced in 1954 the considerations were 1. the dependence of scientific progress in biology on the improvement of existing and the introduction of new methods; 2. the inavailability of many new analytical methods concealed in specialized journals not normally accessible to experimental plant biologists; 3. the fact that in the methods sections of papers the description of methods is frequently so compact, or even sometimes so incomplete, that experiments are difficult to reproduce. These considerations still stand today. The series was highly successful, seven volumes appearing between 1956 and 1964. Since today there is still a demand for the old series, the publisher has decided to resume publication of Modern Methods of Plant Analysis. It is hoped that the New Series will be as acceptable to those working in plant sciences and related fields as the early volumes undoubtedly were. It is difficult to single out the major reasons for success of any publication, but we believe that the methods published in the first series were up-to-date at the time and the descriptions as applied to plant material so complete in themselves that there was little need to consult other publications.

Diese Einführung in die Methoden enthält konkrete Anleitungen zur Durchführung von Experimenten, wie sie jeder Student im Rahmen seiner Praktika zur Pflanzenphysiologie zu absolvieren hat. Diese Experimente sind in zwei Kategorien eingeteilt: zuerst "Demonstrations-Experimente" als in der Regel einfach auszuführende Versuche zur Veranschaulichung bestimmter physiologischer Sachverhalte. Sie haben vor allem didaktischen Charakter und sind weitgehend deduktiv dargestellt. Im Gegensatz dazu stellt die andere Kategorie "Analytische Experimente" vor, für die eine induktive Darstellungsweise gewählt wurde. Das Thema dieser Versuche ist als "Problem" formuliert, und ihre Durchführung wird im Detail nur für ein "Grundexperiment" dargestellt, welches den prinzipiellen experimentellen Ansatz und die Methodenbeschreibung enthält. Mit diesen Anleitungen ist es dann möglich, die entsprechenden physiologischen oder methodischen Fragestellungen selbständig zu bearbeiten.

While there are a few plant cell biology books that are currently available, these are expensive, methods-oriented monographs. The present volume is a textbook for "upper" undergraduate and beginning graduate students." This textbook stresses concepts and is inquiry-oriented. To this end, there is extensive use of original research literature. As we live in an era of literature explosion, one must be selective. These judgements will naturally vary with each investigator. Input was sought from colleagues in deciding the literature to include. In addition to provision of select research literature, this volume presents citations and summaries of certain laboratory methods. In this connection, the textbook stresses quantitative data to enhance the student?s analytical abilities. Thus the volume contains computer-spread sheets and references to statistical packages, e.g. Harvard Graphics and Statistica.

Each animal and plant cell can be constructed of at least ten distinctive types of membrane whose isolation and characterization are now feasible using the wide-ranging techniques presented in this book. Both newly developed and more established methods for the analysis of proteins and lipids and for the investigation of their topography are described in detail. Also provided are procedures for the reconstitution and characterization of membrane systems. Particular attention has been paid to immunological approaches for isolating and analyzing membranes and their components and for screening expression systems in molecular cloning. Those biophysical and physico-chemical techniques which have added much to our understanding of membrane structure and function are also included. The text therefore provides a comprehensive collection of modern techniques and approaches used in the study of biological membranes.

View: 2482

Plant Cell Organelles contains the proceedings of the Phytochemical Group Symposium held in London on April 10-12, 1967. Contributors explore most of the ideas concerning the structure, biochemistry, and function of the nuclei, chloroplasts, mitochondria, vacuoles, and other organelles of plant cells. This book is organized into 13 chapters and begins with an overview of the enzymology of plant cell organelles and the localization of enzymes using cytochemical techniques. The text then discusses the structure of the nuclear envelope, chromosomes, and nucleolus, along with chromosome sequestration and replication. The next chapters focus on the structure and function of the mitochondria of higher plant cells, biogenesis in yeast, carbon pathways, and energy transfer function. The book also considers the chloroplast, the endoplasmic reticulum, the Golgi bodies, and the microtubules. The final chapters discuss protein synthesis in cell organelles; polysomes in plant tissues; and lysosomes and spherosomes in plant cells. This book is a valuable source of information for postgraduate workers, although much of the material could be used in undergraduate courses.

Category: Science

Page: 408

View: 1503

Plant Cell Biology is a semester long course for undergraduates and graduate students which integrates mathematics and physics, two years of chemistry, genetics, biochemistry and evolution disciplines. Having taught this course for over ten years, the author uses his expertise to relate the background established in plant anatomy, plant physiology, plant growth and development, plant taxonomy, plant biochemistry, and plant molecular biology courses to plant cell biology. This integration attempts to break down the barrier so plant cell biology is seen as an entrée into higher science. Distinguishing this book from papers that are often used for teaching the subject which use a single plant to demonstrate the techniques of molecular biology, this book covers all aspects of plant cell biology without emphasizing any one plant, organelle, molecule, or technique. Although most examples are biased towards plants, basic similarities between all living eukaryotic cells (animal and plant) are recognized and used to best illustrate for students cell processes. Thoroughly explains the physiological underpinnings of biological processes to bring original insight related to plants Includes examples throughout from physics, chemistry, geology, and biology to bring understanding to plant cell development, growth, chemistry and diseases Provides the essential tools for students to be able to evaluate and assess the mechanisms involved in cell growth, chromosome motion, membrane trafficking, and energy exchange Companion Web site provides support for all plant cell biology courses
