The series Molecular Methods of Plant Analysis launches the former 'Modern Methods' into the 'molecular' era with this volume on "Taste and Aroma". Analysis of the plant components interacting with these two senses, so important for the very survival of human beings and, in more recent times, the key to their enjoyment of life as well, is presented with examples of the use of molecular approaches. These include DNA microarrays, antisense technology and RNA gel blot analysis. Some recent advances in plant analysis technology embrace amongst others the use of electroantennography in the detection of physiologically important flower volatiles. An introductory chapter explains what we know about the molecular biology of human taste and aroma receptors, as this has implications for the analysis of plant components interacting with these receptors. As the first volume in the molecular series, this book lays the foundation for others to come.

Pollen transmits the male genetic material in sexual reproduction of all higher plants. This same pollen is also well suited as a research tool for studying many patterns of plant and animal metabolism. In addition, an increased knowledge of pollen may help plant breeders accelerate efforts to improve the world's food and fiber supply. This volume focuses upon pollen biology and chemistry; it attempts to inte grate these facts with management practices involved in pollen applications. People have long been involved with pollen. Pollen applications are recorded in the rites of ancient civilizations (see Frontispiece). From the earliest times many benefits have been attributed to the inclusion of pollen in man's diet; also, since the mid-19th century air-borne pollen has been recognized as detrimental to many people's health. Disciplines concerned with man's cultural history and the earth's changing ecology find pollen a particularly useful and accessible tool. Identifiable parts of pollen have survived over 100 million years. But most books dealing with pollen are generally concerned with the identification of the plant source, an aspect of the science of palynology; other books emphasize the natural vectors transmit ting pollen, the pollination mechanisms. Very few works include the biochem istry or biology of pollen. Yet extensive studies by physicians, as well as plant breeders and apiculturists, have contributed a sizeable body of research relating to pollen.

Die papierchromatographische Methode hat auf Grund ihres relativ geringen apparativen Aufwandes, des zu erzielenden hohen Trenneffektes und der zur Analyse benötigten geringen Substanzmengen neue Aspekte für die biochemische Analyse im biologischen Laboratorium geboten. Zahlreiche Probleme sind in Angriff genommen worden, die auf Grund des geringen zur Verfügung stehenden Ausgangsmaterials einer experi mentellen Untersuchung früher nicht zugänglich waren. Vorliegende Dar stellung bringt in 2. Auflage die Anwendung papierchromatographischer Techniken für diejenigen Substanzen, die im Rahmen botanisch-bio chemischer Fragestellungen von Interesse sind. Die Bearbeiter verfügen jeweils über eigene experimentelle Erfahrung im Bereich der dargestellten Stoffgruppe. Die Methoden und ihre Anwendung auf pflanzliche Objekte sind so ausführlich dargestellt, daß ein Nacharbeiten im allgemeinen ohne Hinzuziehen der Originalliteratur möglich ist. Es wurde wiederum nicht angestrebt, alle bisher beschriebenen Methoden zu erfassen. Vielmehr sind die brauchbarsten und erprobten Arbeitsgänge unter besonderer Berück sichtigung der Aufarbeitungsverfahren zusammengetragen. Bezüglich einer ausführlichen theoretischen Grundlegung und der zahlreichen ständig neu entwickelten apparativen Möglichkeiten sei auf die zusammenfassenden Darstellungen in der Bibliographie verwiesen. Mit allem Nachdruck muß wiederum auf die Grenze der papier chromatographischen Methodik hingewiesen werden. Es hat sich in den vergangenen Jahren gezeigt, daß sie zwar eine bedeutsame Erweiterung des methodischen Repertoirs besonders für den Biologen darstellt, jedoch keineswegs die klassischen Verfahren der Mikroanalyse überflüssig macht.
