Book excerpt: 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.

Download or read book Anthocyanins written by Kevin Gould and published by Springer Science & Business Media. This book was released on 2008-12-19 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: With contributions that review research on this topic throughout the world, Oxidative Damage to Plants covers key areas of discovery, from the generation of reactive oxygen species (ROSs), their mechanisms, quenching of these ROSs through enzymatic and non-enzymatic antioxidants, and detailed aspects of such antioxidants as SOD and CAT. Environmental stress is responsible for the generation of oxidative stress, which causes oxidative damage to biomolecules and hence reduces crop yield. To cope up with these problems, scientists have to fully understand the generation of reactive oxygen species, its impact on plants and how plants will be able to withstand these stresses. Provides invaluable information about the role of antioxidants in alleviating oxidative stress Examines both the negative effects (senescence, impaired photosynthesis and necrosis) and positive effects (crucial role that superoxide plays against invading microbes) of ROS on plants Features contributors from a variety of regions globally

Download or read book Bioactive Molecules in Food written by Jean-Michel Mérillon and published by Springer Nature. This book was released on 2019-01-25 with total page 2353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference work provides comprehensive information about the bioactive molecules presented in our daily food and their effect on the physical and mental state of our body. Although the concept of functional food is new, the consumption of selected food to attain a specific effect existed already in ancient civilizations, namely of China and India. Consumers are now more attentive to food quality, safety and health benefits, and the food industry is led to develop processed- and packaged-food, particularly in terms of calories, quality, nutritional value and bioactive molecules. This book covers the entire range of bioactive molecules presented in daily food, such as carbohydrates, proteins, lipids, isoflavonoids, carotenoids, vitamin C, polyphenols, bioactive molecules presented in wine, beer and cider. Concepts like French paradox, Mediterranean diet, healthy diet of eating fruits and vegetables, vegan and vegetarian diet, functional foods are described with suitable case studies. Readers will also discover a very timely compilation of methods for bioactive molecules analysis. Written by highly renowned scientists of the field, this reference work appeals to a wide readership, from graduate students, scholars, researchers in the field of botany, agriculture, pharmacy, biotechnology and food industry to those involved in manufacturing, processing and marketing of value-added food products.

Download or read book The Photoprotective Role of Anthocyanin Pigments in Leaf Tissues written by Nicole Michelle Hughes and published by . This book was released on 2009 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthocyanins are vacuolar pigments most commonly responsible for red to purple coloration in plant tissues. Because they absorb strongly in the blue-green waveband, anthocyanins effectively reduce internal light within the leaf, which may be beneficial under high-light stress conditions. However, pigment patterns in natural systems often appear inconsistent with a photoprotective function (e.g. anthocyanins in abaxial leaf surfaces), and their absence in many species exposed to high-light stress suggests that anthocyanins may not be necessary for photoprotection. Furthermore, the presumed dynamic interaction between anthocyanin synthesis and relative need for photoprotection has yet to be quantitatively described. These issues, among others, have stalled acceptance of a photoprotective function of anthocyanin pigments, and are addressed in the studies presented here. Measurements of leaf optics and chlorophyll fluorescence were used to compare optical and photosynthetic effects of abaxial anthocyanins in vivo. In a species where abaxial leaf surfaces are naturally exposed to high light stress in the field (Galax urceolata), anthocyanins appeared to function similarly to anthocyanins in adaxial surfaces--absorbing strongly in the blue-green wavelengths, and reducing high-light stress (i.e. photoinhibition of photosynthesis). In a shade-adapted, abaxially-red understory species (Begonia heracleifolia), a photoprotective function was also supported, but through attenuation of internally-scattered green light transmitted through the upper leaf surface. This function may be adaptive during periodic exposure to high intensity sunflecks or sun-patches, which are potentially damaging to shade-adapted plants. In developing leaves of three deciduous-tree species, anthocyanin disappearance corresponded with development of ~50% mature photopigment concentrations, ~80% lamina thickness, and differentiation of the mesophyll into palisade and spongy layers. This conserved pattern in anthocyanin loss during development between species is consistent with a controlled coupling of anthocyanin concentration and relative need for photoprotection. Relative photosynthetic capacity was compared for five species exhibiting anthocyanin production in winter leaves and five species lacking anthocyanin. It was expected that species with red winter leaves would correspond with those exhibiting diminished photosynthetic capacity, rendering them in greater need for photoprotection. This hypothesis was not supported, however, and the reason why some species require anthocyanin pigments while others do not during winter remains unknown. In conclusion, these studies are generally consistent with a photoprotective function of anthocyanins in leaf tissues.

This book was released on 2017-12-12 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 500 species distributed all around the Northern Hemisphere, the genus Quercus L. is a dominant element of a wide variety of habitats including temperate, tropical, subtropical and mediterranean forests and woodlands. As the fossil record reflects, oaks were usual from the Oligocene onwards, showing the high ability of the genus to colonize new and different habitats. Such diversity and ecological amplitude makes genus Quercus an excellent framework for comparative ecophysiological studies, allowing the analysis of many mechanisms that are found in different oaks at different level (leaf or stem). The combination of several morphological and physiological attributes defines the existence of different functional types within the genus, which are characteristic of specific phytoclimates. From a landscape perspective, oak forests and woodlands are threatened by many factors that can compromise their future: a limited regeneration, massive decline processes, mostly triggered by adverse climatic events or the competence with other broad-leaved trees and conifer species. The knowledge of all these facts can allow for a better management of the oak forests in the future.
