Abstract

Plasmodesmata are minuscule plasma corridors between plant cells which are of paramount importance for transport, communication and signalling between cells. These nano-channels are responsible for the integrated action of cells within tissues and for the subdivision of the plant body into working symplast units. This book updates the wealth of new information in this rapidly expanding field. Reputed workers in the field discuss major techniques in plasmodesmatal research and describe recent discoveries on the ultrastructure, the functioning and the role of plasmodesmata in intracellular transport and communication, in cell differentiation, plant development and virus translocation.

Abstract

In Plant Cell Culture Protocols, Robert Hall and a panel of expert researchers present a comprehensive collection of the most frequently used and broadly applicable techniques for plant cell and tissue culture. Readily reproducible and extensively annotated, the methods cover culture initiation, maintenance, manipulation, application, and long-term storage, with emphasis on techniques for genetic modification and micropropagation. Many of these protocols are currently used in major projects designed to produce improved varieties of important crop plants. In addition, a number of specialized protocols have been included to illustrate the diversity of the techniques available and their widespread applicability. Plant Cell Culture Protocols is aimed at scientists involved in all aspects of plant biotechnological research, as well as those working in other areas of agriculture and horticulture who are interested in expanding their technical repertoire to include in vitro methodology. Its state-of-the-art techniques are certain to make the book today's reference of choice, an indispensable tool in the development of new transgenic plants and full-scale commercial applications.

Abstract

Food and raw material for its production was generally produced via the traditional agriculture. On the other hand, novel chemicals were manufactured in the laboratory or extracted from plant and animal sources. However, as the world population is steadily in­ creasing, there is a decrease in traditional agriculture productivity and concerns are also expressed over the damage inflicted to the environment and restrictions that might be en­ forced in food production. At the same time, there is an increasing demand for high qual­ ity agricultural products as well as for food ingredients related to both the traditional or newly discovered nutrients or phytochemicals. Trends and developments,~n the area of plant biotechnology and bioengineering has allowed manipulation of genes' !lnd/or insertion of new genes, thus production of trans­ genic plants. Starting from the introduction of agronomic traits, particularly stress resis­ tance to diverse environmental factors, process and sensory characteristics, food quality and production of novel varieties of plant-based products through genetic engineering, biotechnology is changing the,;agriculture and the concept of production of plant-ba~~d raw materials. Increasing attention is being paid on research for production of plants !pat can provide a wide array of food and non-food products. Perhaps the first non-food pro,d­ uct that plant biotechnology would achieve is production of large scale custom-designed industrial oils, but the list of chemicals is long, ranging" from oils and specific triacyl­ glycerols to biopolymers, enzymes, blood components, amo~g others.

Abstract

Bioassay Methods in Natural Product Research and Drug Development contains the proceedings from the Phytochemical Society of Europe's very successful symposium on this topic, held August 24-27, 1997 in Uppsala, Sweden. In this volume, leading academic and industrial scientists discuss novel methods for assaying natural products to find new structure-activity relationships. Of key importance in this process is the availability and reliability of specific bioassay methods, but chapters also discuss chemical and biological diversity and how to dereplicate natural product extracts to increase efficiency in lead discovery. Anti-tumor, HIV-inhibitory, antiprotozoal, anti-infective and immunomodulatory natural products are discussed. Various industrial projects are presented for the first time. This volume bridges the gap between academic and industrial research and scientists, and should be required reading in drug companies and faculties of pharmacy, as well as serving scientists in pharmacognosy, pharmacology, phytochemistry, natural products and drug discovery.

Abstract

Fungi are among the most versatile and diverse groups of organisms in their morphology, life cycles, and ecology. This has provided endless fasci­ nation and intrigue to those who have studied fungi, but it has also made it difficult to understand fungal biology from the perspective of the broader fields of evolution, ecology, genetics, and population biology. That is changing. Details of fungal biology have been elucidated at an exciting pace, increasingly allowing us to understand fungi on the bases of general biological principles. Moreover, many who study fungi have lately emulated some of the great mycologists and plant pathologists of the early years in applying an insight born of broad perspective. This change has been particularly apparent in fungal population biology. In this book, many of those at the forefront of that change summarize, integrate and comment on recent developments and ideas on populations of fungi. By taking a broad perspective, they show how new information on fungi may contribute to concepts and ideas of biology as a whole. Just as important, they contribute to further invigoration of fungal population research by illuminating mycology with new ideas and concepts, derived in part from other biological fields.

Abstract

Modern methods and approaches, such as the analysis of molecular sequences to infer evolutionary relationships among organisms, have provided vast new sets of data to further our understanding ofliving organisms, but there remain enigmas in the biological world that will keep scientists working and thinking for decades. Microorganisms by virtue of their small size and almost unbounded diversity provide ample examples of intriguing mysteries that are being challenged with all of the techniques the modern scientific arsenal can provide. One whole arena of this battle to resolve puzzling mysteries about various microorganisms is the almost unbelievable ability of many micro-organisms to live in extreme environments. Whether the challenge is extreme heat, cold, pressure, hyper­ salinity, alkalinity or acidity, some micro-organisms live now where no life might seem possible. This fascinating state of affairs is the context for this present volume edited by Joseph Seckbach. This Volume is a compilation of many of the especially interesting questions and biological challenges that arise in the consideration of microorganisms in general and the extremophiles in particular.
