Anthocyanins are the pigments in leaves and fruits that give them their colour; for example, the red colour of strawberries, or red leaves in autumn. Although these pigments are especially prominent in the autumn foliage of deciduous trees and in the growth flushes of tropical rainforest plants, they are also found in the leaves of many species after exposure to environmental or biotic stresses. Although the control of anthocyanin synthesis in vegetative organs has long been studied, and is a model system in plant molecular genetics, potential functions of these pigments in leaves have been largely ignored. This volume pulls together new information from experts in the fields of genetics, biochemistry, molecular biology, physiological ecology and plant development, providing a platform to discuss putative hypotheses for anthocyanin function in these vegetative organs.

In recent years there has been an unprecedented expansion of knowledge about anthocyanins pigments. Indeed, the molecular genetic control of anthocyanins biosynthesis is now one of the best understood of all secondary metabolic pathways. There have also been substantial improvements in analytical technology that have led to the discovery of novel anthocyanin compounds. Armed with this knowledge and the tools for genetic engineering, plant breeders are now introducing vibrant new colors into horticultural crops. The food industry has also benefited from the resurgence of interest in anthocyanins. A greater understanding of the chemistry of these pigments has led to improved methods for stabilizing the color of anthocyanins extracts, so that they are more useful as food colorings. Methods for the bulk production of anthocyanins from cell cultures have been optimized for this purpose. Possible benefits to human health from the ingestion of anthocyanin-rich foods have also been a major feature of the recent scientific literature. Anthocyanins are remarkably potent antioxidants, and their ingestion has been postulated to stave off the effects of oxidative stress. These pigments, especially in conjunction with other flavonoids, have been associated with reductions in the incidence and severity of many other non-infectious diseases, including diabetes, cardiovascular disease and certain cancers. An industry is developing around anthocyanins as nutritional supplements. Finally, there has been significant progress in our understanding of the benefits of anthocyanins to plants themselves. Originally considered an extravagance without a purpose, anthocyanins are now implicated in multifarious vital functions. These include the attraction of pollinators and frugivores, aposematic defense from herbivores, and protection from environmental stressors such as strong light, UVB, drought, and free radical attacks. Anthocyanins are evidently highly versatile, and enormously useful to plants. This book covers all aspects of the biosynthesis and function of anthocyanins (and related compounds such as proanthocyanidins) in plants, and their applications in agriculture, food products, and human health. Featured areas include their relevance to: * Plant stress * Flower and fruit color * Human health * Wine quality and health attributes * Food colorants and ingredients * Cell culture production systems * The pastoral sector

Since Kentucky is situated at a biological crossroads in eastern North America, citizens and visitors to this beautiful state are likely to be greeted by an astonishing variety of wildflowers. This non-technical guide -- featuring more than five hundred dazzling full-color photographs by award-winning photographer Thomas G. Barnes -- is the state's indispensable guide to the most common species in the Commonwealth. With this book, readers will learn to identify and appreciate Kentucky wildflowers and ferns by matching photographs and leaf line drawings to the more than six hundred and fifty species of flowers covered in the book. Extremely practical and simple to use, the guide's color photographs and line drawings appear with plant descriptions for easy identification, and plants are grouped by flower color and blooming season. Each species listing includes the plant's common and scientific name, plant family, habitat, frequency, and distribution throughout Kentucky, with similar species listed in the notes. There is no other volume that covers the flora of Kentucky with such ease of identification. The first new statewide guide to appear in thirty years, with its combination of high quality photographs, illustrations, portability, and easy organization of information, Wildflowers and Ferns of Kentucky is an essential addition to the library or field pack of the wildflower enthusiast, naturalist, and anyone else who loves the outdoors.
