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

Book Synopsis The Leaf: A Platform for Performing Photosynthesis by : William W. Adams III
Download or read book The Leaf: A Platform for Performing Photosynthesis written by William W. Adams III and published by Springer. This book was released on 2018-10-24 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: The leaf is an organ optimized for capturing sunlight and safely using that energy through the process of photosynthesis to drive the productivity of the plant and, through the position of plants as primary producers, that of Earth’s biosphere. It is an exquisite organ composed of multiple tissues, each with unique functions, working synergistically to: (1) deliver water, nutrients, signals, and sometimes energy-rich carbon compounds throughout the leaf (xylem); (2) deliver energy-rich carbon molecules and signals within the leaf during its development and then from the leaf to the plant once the leaf has matured (phloem); (3) regulate exchange of gasses between the leaf and the atmosphere (epidermis and stomata); (4) modulate the radiation that penetrates into the leaf tissues (trichomes, the cuticle, and its underlying epidermis); (5) harvest the energy of visible sunlight to transform water and carbon dioxide into energy-rich sugars or sugar alcohols for export to the rest of the plant (palisade and spongy mesophyll); and (6) store sugars and/or starch during the day to feed the plant during the night and/or acids during the night to support light-driven photosynthesis during the day (palisade and spongy mesophyll). Various regulatory controls that have been shaped through the evolutionary history of each plant species result in an incredible diversity of leaf form across the plant kingdom. Genetic programming is also flexible in allowing acclimatory phenotypic adjustments that optimize leaf functioning in response to a particular set of environmental conditions and biotic influences experienced by the plant. Moreover, leaves and the primary processes carried out by the leaf respond to changes in their environment, and the status of the plant, through multiple regulatory networks over time scales ranging from seconds to seasons. This book brings together the findings from laboratories at the forefront of research into various aspects of leaf function, with particular emphasis on the relationship to photosynthesis.

Book Synopsis Photoprotection in Plants by : Alexei Solovchenko
Download or read book Photoprotection in Plants written by Alexei Solovchenko and published by Springer Science & Business Media. This book was released on 2010-08-18 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical screening of excessive and potentially harmful solar radiation is an important photoprotective mechanism, though it has received much less attention in comparison with other systems preventing photooxidative damage to photoautotrophic organisms. This photoprotection in the form of screening appears to be especially important for juvenile and senescing plants as well as under environmental stresses—i.e. in situations where the efficiency of enzymatic ROS elimination, DNA repair and other ‘classical’ photoprotective systems could be impaired. This book represents an attempt to develop an integral view of optical screening-based photoprotection in microalgae and higher plants. Towards this end, the key groups of pigments involved in the screening of ultraviolet and visible components of solar radiation in microalgae and higher plants, and the patterns of their accumulation and distribution within plant cells and tissues, are described. Special attention is paid to the manifestations of screening pigment accumulation in the optical spectra of plants. It is also demonstrated that understanding these effects and their relationships to screening pigments’ makeup and spectroscopy in plants provides valuable insights into the state of plants’ long-term photoacclimation, as well as ample opportunities for the non-destructive quantification of screening pigments and the assessment of the efficiency of photoprotection providing by these pigments in situ.
Book Synopsis Environmental Adaptations and Stress Tolerance of Plants in the Era of Climate Change by : Parvaiz Ahmad
Download or read book Environmental Adaptations and Stress Tolerance of Plants in the Era of Climate Change written by Parvaiz Ahmad and published by Springer Science & Business Media. This book was released on 2011-12-02 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is a complex phenomenon with a wide range of impacts on the environment. Biotic and abiotic stress are a result of climate change. Abiotic stress is caused by primary and secondary stresses which are an impediment to plant productivity. Prolonged exposure to these stresses results in altered metabolism and damage to biomolecules. Plants evolve defense mechanisms to withstand these stresses, e.g. synthesis of osmolytes, osmoprotectants, and antioxidants. Stress responsive genes and gene products including expressed proteins are implicated in conferring tolerance to the plant. This volume will provide the reader with a wide spectrum of information, including vital references. It also provides information as to how phytoconstituents, hormones and plant associated microbes help the plants to tolerate the stress. This volume also highlights the use of plant resources for ameliorating soil contaminants such as heavy metals. Dr. Parvaiz is Assistant professor in Botany at A.S. College, Srinagar, Jammu and Kashmir, India. He has completed his post-graduation in Botany in 2000 from Jamia Hamdard New Delhi India. After his Ph.D from the Indian Institute of Technology (IIT) Delhi, India in 2007 he joined the International Centre for Genetic Engineering and Biotechnology, New Delhi. He has published more than 20 research papers in peer reviewed journals and 4 book chapters. He has also edited a volume which is in press with Studium Press Pvt. India Ltd., New Delhi, India. Dr. Parvaiz is actively engaged in studying the molecular and physio-biochemical responses of different plants (mulberry, pea, Indian mustard) under environmental stress. Prof. M.N.V. Prasad is a Professor in the Department of Plant Sciences at the University of Hyderabad, India. He received B.Sc. (1973) and M.Sc.

Book Synopsis The Forest Unseen by : David George Haskell
Download or read book The Forest Unseen written by David George Haskell and published by Penguin. This book was released on 2012-03-15 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: A biologist reveals the secret world hidden in a single square meter of old-growth forest—a finalist for the Pulitzer Prize and the Pen/E.O. Wilson Literary Science Writing Award Combining elegant writing with scientific expertise, The Forest Unseen "injects much-needed vibrancy into the stuffy world of nature writing" (Outside, "The Outdoor Books That Shaped the Last Decade") In this wholly original book, biologist David Haskell uses a one- square-meter patch of old-growth Tennessee forest as a window onto the entire natural world. Visiting it almost daily for one year to trace nature's path through the seasons, he brings the forest and its inhabitants to vivid life. Each of this book's short chapters begins with a simple observation: a salamander scuttling across the leaf litter; the first blossom of spring wildflowers. From these, Haskell spins a brilliant web of biology and ecology, explaining the science that binds together the tiniest microbes and the largest mammals and describing the ecosystems that have cycled for thousands- sometimes millions-of years. Each visit to the forest presents a nature story in miniature as Haskell elegantly teases out the intricate relationships that order the creatures and plants that call it home. Written with remarkable grace and empathy, The Forest Unseen is a grand tour of nature in all its profundity. Haskell is a perfect guide into the world that exists beneath our feet and beyond our backyards.

Book Synopsis UV-B Radiation by : Vijay Pratap Singh
Download or read book UV-B Radiation written by Vijay Pratap Singh and published by John Wiley & Sons. This book was released on 2017-02-02 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultraviolet-B (UV-B) is electromagnetic radiation coming from the sun, with a medium wavelength which is mostly absorbed by the ozone layer. The biological effects of UV-B are greater than simple heating effects, and many practical applications of UV-B radiation derive from its interactions with organic molecules. It is considered particularly harmful to the environment and living things, but what have scientific studies actually shown? UV-B Radiation: From Environmental Stressor to Regulator of Plant Growth presents a comprehensive overview of the origins, current state, and future horizons of scientific research on ultraviolet-B radiation and its perception in plants. Chapters explore all facets of UV-B research, including the basics of how UV-B's shorter wavelength radiation from the sun reaches the Earth's surface, along with its impact on the environment's biotic components and on human biological systems. Chapters also address the dramatic shift in UV-B research in recent years, reflecting emerging technologies, showing how historic research which focused exclusively on the harmful environmental effects of UV-B radiation has now given way to studies on potential benefits to humans. Topics include: UV-B and its climatology UV-B and terrestrial ecosystems Plant responses to UV-B stress UB- B avoidance mechanisms UV-B and production of secondary metabolites Discovery of UVR8 Timely and important, UV-B Radiation: From Environmental Stressor to Regulator of Plant Growth is an invaluable resource for environmentalists, researchers and students who are into the state-of-the-art research being done on exposure to UV-B radiation.

Book Synopsis The Photoprotective Role of Anthocyanin Pigments in Leaf Tissues by : Nicole Michelle Hughes
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.
