Not since the late 1970s has a single work presented the biology of this heterogenous group of secondary alkaloids in such depth. Alkaloids, a unique treatise featuring leaders in the field, presents both the historical use of alkaloids and the latest discoveries in the biochemistry of alkaloid production in plants alkaloid ecology, including marine invertebrates, animal and plant parasites, and alkaloids as antimicrobial and current medicinal use . Highlights include chapters on the chemical ecology of alkaloids in host-predator interactions, and on the compartmentation of alkaloids synthesis, transport, and storage. Extensive cross-referencing in tabular format makes this volume an excellent reference.

This field of research examines how embodied and situated agents, such as robots, evolve language and thus communicate with each other. This book is a comprehensive survey of the research in this emerging field. The contributions explain the theoretical and methodological foundations of the field, and then illustrate the scientific and technological potentials and promising research directions. The book also provides descriptions of research experiments and related open software and hardware tools, allowing the reader to gain a practical knowledge of the topic. The book will be of interest to scientists and undergraduate and graduate students in the areas of cognition, artificial life, artificial intelligence and linguistics.

The discipline of Synthetic Biology has recently emerged at the interface of biology and engineering. The definition of Synthetic Biology has been dynamic over time ever since, which exemplifies that the field is rapidly moving and comprises a broad range of research areas. In the frame of this Research Topic, we focus on Synthetic Biology approaches that aim at rearranging biological parts/ entities in order to generate novel biochemical functions with inherent metabolic activity. This Research Topic encompasses Pathway Engineering in living systems as well as the in vitro assembly of biomolecules into nano- and microscale bioreactors. Both, the engineering of metabolic pathways in vivo, as well as the conceptualization of bioreactors in vitro, require rational design of assembled synthetic pathways and depend on careful selection of individual biological functions and their optimization. Mathematical modelling has proven to be a powerful tool in predicting metabolic flux in living and artificial systems, although modelling approaches have to cope with a limitation in experimentally verified, reliable input variables. This Research Topic puts special emphasis on the vital role of modelling approaches for Synthetic Biology, i.e. the predictive power of mathematical simulations for (i) the manipulation of existing pathways and (ii) the establishment of novel pathways in vivo as well as (iii) the translation of model predictions into the design of synthetic assemblies.

Nunmehr liegt die 2., grA1/4ndlich A1/4berarbeitete und aktualisierte Auflage des gut eingefA1/4hrten Lehrbuches von Hans-Walter Heldt, einem der renommiertesten deutschen Pflanzenbiochemiker, vor. Der Autor spannt den Bogen von der Photosynthese A1/4ber PrimAr- und SekundArstoffwechsel sowie Phytohormone bis hin zu aktuellen Themen wie Molekulargenetik und Gentechnik. Die Pflanzenbiochemie ist auch auf vielen Feldern der angewandten Forschung von groAer Bedeutung, etwa in der Pflanzenzucht und Biotechnologie sowie der Wirkstoff-Forschung an Pflanzen. Neueste wissenschaftliche Erkenntnisse fanden Eingang in dieses Buch, und an vielen Stellen zeigt der Autor die Grenzen unseres derzeitigen Wissens auf. Kompetenz und AktualitAt, klare Darstellung und gute VerstAndlichkeit - das sind die Kennzeichen dieses Lehrbuches. Mit sorgfAltig erstellten zweifarbigen Abbildungen erfA1/4llt es einen hohen didaktischen Anspruch und reiht sich unter die besten Biochemie-LehrbA1/4cher. ((Foto wie auf 1. Auflage, liegt sicherlich in Produktion als Film)) Prof. Dr. Hans-Walter Heldt, Jahrgang 1934, leitet die Abteilung fA1/4r Biochemie der Pflanze am Albrecht-von-Haller-Institut fA1/4r Pflanzenwissenschaften der UniversitAt GAttingen. Seine Forschungsinteressen gelten dem Photosynthese-Stoffwechsel hAherer Pflanzen und dem Metabolitentransport. FA1/4r seine Arbeiten wurde er 1993 mit dem Max-Planck-Forschungspreis ausgezeichnet. Dozentenstimmen zur 1. Auflage: ”Das Buch hat den Mut, komplexe Sachverhalte einfach darzustellen und notfalls auf die letzten Feinheiten und Varianten zu verzichten. Trotzdem bleibt die Darstellung korrekt, und sie ist auf dem aktuellen Stand. Das ist genau das, was die Studenten brauchen.>Pflanzenbiochemie aus einem GuA; in der Tiefe und in der Breite mit groAem VerstAndnis fA1/4r Regulation und Funktionen in der ganzen Pflanze.

Phytochemicals from medicinal plants are receiving ever greater attention in the scientific literature, in medicine, and in the world economy in general. For example, the global value of plant-derived pharmaceuticals will reach $500 billion in the year 2000 in the OECD countries. In the developing countries, over-the-counter remedies and "ethical phytomedicines," which are standardized toxicologically and clinically defined crude drugs, are seen as a promising low cost alternatives in primary health care. The field also has benefited greatly in recent years from the interaction of the study of traditional ethnobotanical knowledge and the application of modem phytochemical analysis and biological activity studies to medicinal plants. The papers on this topic assembled in the present volume were presented at the annual meeting of the Phytochemical Society of North America, held in Mexico City, August 15-19, 1994. This meeting location was chosen at the time of entry of Mexico into the North American Free Trade Agreement as another way to celebrate the closer ties between Mexico, the United States, and Canada. The meeting site was the historic Calinda Geneve Hotel in Mexico City, a most appropriate site to host a group of phytochemists, since it was the address of Russel Marker. Marker lived at the hotel, and his famous papers on steroidal saponins from Dioscorea composita, which launched the birth control pill, bear the address of the hotel.
