Pigment of the Imagination chronicles the story of phytochrome, the bright-blue photoreversible pigment through which plants constantly monitor the quality and presence of light. The book begins with work that led to the discovery of phytochrome and ends with the latest findings in gene regulation and expression. The phytochrome story provides a paradigm for the process of scientific discovery. This book should thus be of interest to scientists who work on phytochrome and related subjects in plant science, as well as to all scientists and science historians interested in how a scientific research field begins, develops, and matures. Documents the science and history of phytochrome research over an 80 year span Combines information from scientific literature, archival documents, and in-person inteviews Describes in scholarly and readable style an elegant example of biological discovery Accessible to researchers and students in all areas of science and history of science

It is perhaps not surprising that plants have evolved a mechanism to sense the light environment about them and to modify growth for optimal use of the available `life-giving' light. Green plants, and ultimately all forms of life, depend on the energy of sunlight fixed during photosynthesis. Unlike animals that use behaviour to find food, sedentary plants use physiology to optimize their growth and development for light absorption. By appreciating the quality, quantity, direction and duration of light, plants can control such complex processes as germination, growth and flowering. To perceive the light environment several receptor pigments have evolved, including the red/far-red reversible phytochrome and the blue/UV-absorbing photoreceptors (Part 1). The quantification of light (Part 2) and importance of instrumentation for photomorphogenesis research are introduced in Part 3. Isolation and characterization of phytochrome is a classic example of how photobiological techniques can predict the nature of an unknown photoreceptor. Current knowledge of the phytochrome photoreceptor family is given in Part 4 and that of blue/UV receptors in Part 5. Part 6 deals with the coaction of photoreceptors. The light environment and its perception is addressed in Part 7. Molecular and genetic approaches and the photoregulation of gene expression compose Part 8. Part 9 contains further selected topics: photomodulation of growth phototropism, photobiology of stomatal movements, photomovement, photocontrol of flavonoid biosynthesis, photobiology of fungi and photobiology of ferns. The 28 chapters written by leading experts from Europe, Israel, Japan and the USA, provide an advanced treatise on the exciting and rapidly developing field of plant photomorphogenesis.

Excluding the biological polymers proteins, lipids and nucleic acids, modified tetrapyrroles are the biological molecules that have had the greatest impact on the evolution of life over the past 4 billion years. They are involved in a wide variety of fundamental processes that underpin central primary metabolism in all kingdoms of life, from photosynthesis to methanogenesis. Moreover, they bring colour into the world and it is for this reason that these compounds have been appropriately dubbed the ‘pigments of life’. To understand how and why these molecules have been so universally integrated into the life processes one has to appreciate the chemical properties of the tetrapyrrole scaffold and, where appropriate, the chemical characteristics of the centrally chelated metal ion. This book addresses why these molecules are employed in Nature, how they are made and what happens to them after they have finished their usefulness.

As our understanding of the science and functions of color in food has increased, the preferred colorants, forms of use, and legislation regulating their uses have also changed. Natural Colorants for Food and Nutraceutical Uses reflects the current tendency to use natural pigments. It details their science, technology, and applications as well as their nutraceutical properties. Starting with the basics, the book creates an understanding of physical colors, discusses color measurement, and analyzes why natural pigments are preferred today. The authors present an overview of global colorants, including safety, toxicity and regulatory aspects. Information about inorganic and synthetic colorants is included. The book then focuses on applications of natural colorants, with special attention given to characteristics, extraction and processing stability, and the use of biotechnology and molecular biology to increase colorant production. Finally, the book examines the nutraceutical properties of natural colorants and compares them to other well-known nutraceutical components. From the basics to highly specialized concepts and applications, Natural Colorants for Food and Nutraceutical Uses presents essential, practical information about pigments in the food industry. With its coverage of state-of-the-art technologies and future trends in the application of color to food, this book provides the most comprehensive, up-to-date survey of the field.
