Biochemistry and Physiology of Polyamines in Plants provides a comprehensive introduction to commonly used methods in polyamine research and the problems unique to plant studies. Topics discussed include polyamine metabolism in plants, the functions of polyamines in plant growth and development, and an examination of analytical methods for polyamines and enzymes of polyamine metabolism. Agronomists, plant physiologists, and biochemists interested in polyamines in plants will find this book to be a valuable reference resource.
The area of polyamines is presented in this useful, two-volume publication. Basic information describing the role of polyamines in the processes of growth and differentiation is given. Also included are data on the regulation of polyamine biosynthesis and metabolism and their interactions with nucleic acids. Several chapters are devoted to the role of polyamines in various aspects of plant biology, with a special emphasis on their participation in the response of plants to extreme environments. Special attention is given to the use of inhibitors of polyamine biosynthesis as potential antitumor and antiproliferative agents. Additionally, progress in the molecular biology and genetic engineering of genes coding for polyamine biosynthetic enzymes is described. Cancer researchers, biologists, geneticists, biochemists, physiologists, and clinicians will find this volume indispensable.

This book covers key topics in polyamine research from a range of organisms, including plants, mammals, and prokaryotes such as bacteria and archaea. The book provides an introduction to general concepts in the field of polyamine research, as well as more detailed information. With the availability of genome sequence data from a broad range of organisms, the evolution of the genes involved in polyamine metabolism is discussed. The mode of action of polyamines has been shown to be dependent on cation channels, and this mechanism is described in the book. The origin of polyamine transporters (from bacteria, yeasts, and plants) is described. The various effects of polyamines on growth and survival are also documented. The book details the mechanisms of polyamine homeostasis and the role of polyamine molecules as precursors of secondary metabolites such as plant alkaloids and toxins derived from spiders and wasps. The role of polyamines in longevity and disease is discussed. A link between polyamine contents and cancer progression is reported, as is the use of polyamine metabolites as diagnostic markers in the initial stages of cancer. Moreover, a novel approach that utilizes the polyamine pathway of a parasite as a drug target in African sleeping sickness is described. Therefore, this book is a valuable resource, both as a textbook for undergraduate and graduate students and also as a reference book for front-line polyamine researchers.
The importance of polyamines for all living cells has been recognized since spermine was discovered in human semen more than 300 years ago. Polyamine research intensified when analytical methods were developed for their determination, particularly in tissues and biological fluids. Discovering their close correlation with cancer, and that polyamine concentrations change during the cell cycle, gave reason for further research in this topic. Polyamines in Health and Nutrition concentrates on the direction of polyamine research which has the capacity to influence and benefit our health and which can explain some of the discrepancies and failures of earlier research. It is important to recognize the dietary contribution to the polyamine body pool and to investigate how the polyamine content of the diet can be changed, with the ultimate aim of using this information to improve our health.
