The 15th International Symposium on Plant Lipids was held in Okazaki, Japan, in May 12th to 17th, 2002, at the Okazaki Conference Center. The Symposium was organized by the Japanese Organizing Committee with the cooperation of the Japanese Association of Plant Lipid Researchers. The International Symposium was successful with 225 participants from 29 countries. We acknowledge a large number of participants from Asian countries, in particular, from China, Korea, Malaysia, Taiwan, Thailand and the Philippines, presumably because this was the fIrst time that the International Symposium on Plant Lipids was held in Asia. We also acknowledge a number of scientists from Canada, France, Germany, UK and USA, where plant lipid research is traditionally very active. The Symposium provided an opportunity for presentation and discussion of 68 lectures and 93 posters in 11 scientific sessions, which together covered all aspects of plant lipid researches, such as the structure, analysis, biosynthesis, regulation, physiological function, environmental aspects, and the biotechnology of plant lipids. In memory of the founder of this series of symposia, the Terry Galliard Lecture was delivered by Professor Ernst Heinz from Universitat: Hamburg, Germany. In addition, special lectures were given by two outstanding scientists from animal lipid fields, Professor James Ntambi from University of Wisconsin, USA, and Dr. Masahiro Nishijima from the National Institute for Infectious Diseases, Japan. To our great honor and pleasure, the session of Lipid Biosynthesis was chaired by Dr.

A collection of papers that comprehensively describe the major areas of research on lipid metabolism of plants. State-of-the-art knowledge about research on fatty acid and glycerolipid biosynthesis, isoprenoid metabolism, membrane structure and organization, lipid oxidation and degradation, lipids as intracellular and extracellular messengers, lipids and environment, oil seeds and gene technology is reviewed. The different topics covered show that modern tools of plant cellular and molecular biology, as well as molecular genetics, have been recently used to characterize several key enzymes of plant lipid metabolism (in particular, desaturases, thioesterases, fatty acid synthetase) and to isolate corresponding cDNAs and genomic clones, allowing the use of genetic engineering methods to modify the composition of membranes or storage lipids. These findings open fascinating perspectives, both for establishing the roles of lipids in membrane function and intracellular signalling and for adapting the composition of seed oil to the industrial needs. This book will be a good reference source for research scientists, advanced students and industrialists wishing to follow the considerable progress made in recent years on plant lipid metabolism and to envision the new opportunities offered by genetic engineering for the development of novel oil seeds.

This short text is designed to provide basic information about plant and microbial lipids not only for scientists working in the microbiological and plant fields, but for anyone wanting a concise introduction to this aspect of lipid biochemistry. We have long been aware that standard biochemistry books tend to. concentrate (sometimes exclusively) on animal lipids, thus neglecting many of the important and special features of other organisms. It is not our intention that the book should be comprehensive and we have not, for instance, provided complete lists of lipid compositions of all plants and bacterial species; a number of excellent specialist texts exist and many of these are listed for further reading. Instead we have sought to provide sufficient information for an advanced undergraduate or a research student to give them a 'feel' for the subject. By a combination of generalisation and the use of examples of special interest we hope the book will whet the appetite of the reader so that, by their own research, they are stimulated to discover and, perhaps, answer some of the fascinating questions concerning plant and microbial lipids. We trust that we shall succeed in these aims, even if that will mean more competition for research funds in our own fields! J. L. HARWOOD N. J. RUSSELL November 1983 Acknowledgements Our research careers have been devoted to a study of lipids: we have no regrets and are happy to acknowledge Professors J. N.

Lipids in Photosynthesis: Essential and Regulatory Functions, provides an essential summary of an exciting decade of research on relationships between lipids and photosynthesis. The book brings together extensively cross-referenced and peer-reviewed chapters by prominent researchers. The topics covered include the structure, molecular organization and biosynthesis of fatty acids, glycerolipids and nonglycerolipids in plants, algae, lichens, mosses, and cyanobacteria, as well as in chloroplasts and mitochondria. Several chapters deal with the manipulation of the extent of unsaturation of fatty acids and the effects of such manipulation on photosynthesis and responses to various forms of stress. The final chapters focus on lipid trafficking, signaling and advanced analytical techniques. Ten years ago, Siegenthaler and Murata edited "Lipids in Photosynthesis: Structure, Function and Genetics," which became a classic in the field. "Lipids in Photosynthesis: Essential and Regulatory Functions," belongs, with its predecessor, in every plant and microbiological researcher's bookcase.

A review of the most recent advances in plant lipid biosynthesis, particularly relevant to industry.
