Download or read book Biosynthesis of Bioactive Compounds in Medicinal and Aromatic Plants written by Nitish Kumar and published by Springer Nature. This book was released on 2023-09-12 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant bioactive compounds are plant-based natural products that display a variety of pharmacological applications. These bioactive compounds are important as medicines, pigments and flavorings since most of the pharmaceutical industries are highly dependent on medicinal plants and their extraction. The types and concentrations of bioactive compounds produced by plants are determined by the species, genotype, physiology, developmental stage and environmental factors during growth, determining the physiological adaptive responses employed by various plant taxonomic groups in coping with the stress and defensive stimuli. In the past two decades there has been a renewed interest in the study of conventional aspects such as elicitors and biotic and abiotic stress factors that influence secondary metabolism during in vitro and in vivo growth of plants. the application of molecular biology tools and techniques are facilitating increased understanding of the signaling processes and pathways involved in the bioactive compounds production in subcellular, cellular, organ and whole plant systems during in vivo and in vitro growth, with application in the metabolic engineering of biosynthetic pathways intermediates. Biosynthesis and Manipulation of Bioactive compounds in Medicinal and Aromatic Plants provides a comprehensive introduction and review of the state-of-the-art biotechnological tools used in enhancement of bioactive compounds in medicinal and aromatic plants. Readers will find a systematic overview of techniques such as Omics, Crisper /Cas9 and RNAi to enhance plant bioactive contents including various in vitro techniques, hairy root culture and transgenic technology to enhance plant bioactive contents using plant tissue culture approaches. The chapters provide an overview of the role of induced mutation, biotic and abiotic stress to increase the bioactive contents in plants, plus the role of endophytes to enhance the contents of plant bioactive compounds and standard operating procedures using hydroponics system of cultivation for significant enhancement of bioactive compounds. This book serves as a single source for researchers working in plant secondary metabolites and the pharmaceutical industry.

Download or read book Atlas of Stem Anatomy in Herbs Shrubs and Trees written by Fritz Hans Schweingruber and published by Springer Science & Business Media. This book was released on 2012-09-07 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work, published in two volumes, contains descriptions of the wood and bark anatomies of 3000 dicotyledonous plants of 120 families, highlighting the anatomical and phylogenetic diversity of dicotyledonous plants of the Northern Hemisphere. The first volume principally treats families of the Early Angiosperms, Eudicots, Core Eudicots and Rosids, while the second concentrates on the Asterids. Presented in Volume 2 are microsections of the xylem and phloem of herbs, shrubs and trees of 1000 species and ca. 35 families of various life forms of the temperate zone along altitudinal gradients from the lowland at the Mediterranean coast to the alpine zone in Western Europe. Special attention is given to the very diverse family of Asteraceae. The global perspective of the findings is underlined by the analysis of 400 species from the Caucasus, the Rocky Mountains and Andes, the subtropical zone on the Canary Islands, the arid zones in the Sahara, in Eurasia, Arabia and Southwest North America, New Zealand and the boreal and arctic zones in Eurasia and Canada. The presence of annual rings in all life forms demonstrates that herbs and dwarf shrubs are an excellent tool for the reconstruction of annual biomass production and the interannual dynamic of plant associations. The common principle of the anatomical expression of secondary growth is a key factor in understanding evolution and adaptation processes in all life forms, from the 3 cm tall crepide pigmea (Crepis pygmaea) in the alpine zone to the 40 m tall ash (Fraxinus excelsior) in Central European riparian forests. The study opens vast fields of research for dendrochronology, wood anatomy, taxonomy and ecology.

Download or read book Sabkha Ecosystems written by M. Ajmal Khan and published by Springer. This book was released on 2014-05-12 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable development is the key for the survival in 21st century. The natural resources are finite and cannot be used with impunity because we are the custodian of these resources and have responsibility to pass these to the next generation. This monumental task requires several major commitments and most important of them is to arrest population explosion which has already reached seven billion. Natural resources like air to breath, food to eat, and water to drink, and fossil fuel to maintain this life style are being overexploited. Unrestrained consuming culture will accelerate undesired situation. This situation will have more dire consequences in resource limited ecosystems like dry lands. Given the severe scarcity of water, ever increasing population and soil salinization out of the box solutions for the provision of food and clean energy is required to spare meager fresh water resources for conventional agriculture. This volume contains a number of articles dealing with halophyte ecology, bio-geography, ecophysiology, hyper-saline soils, biofuels, biosaline agriculture, biosaline landscaping, climate change mitigation, and biodiversity. It also contains the communication of innovative ideas, such as the research into floating mangroves, seagrass terraces, as well as a World Halophyte Garden containing all known salt-tolerant plant species. It is hoped that the information provided will not only advance vegetation science, but that it will truly generate more interdisciplinarity, networking, awareness, and inspire farmers, and agricultural and landscaping stakeholders to seriously engage in halophyte cash crop production in coastal hyper-saline areas.

Download or read book Global Perspectives on Underutilized Crops written by Munir Ozturk and published by Springer. This book was released on 2018-05-17 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increase in world population, extreme weather conditions, decrease in fresh water supplies, and changes of dietary habits are major issues that affect global food security. We are expected to face the challenges of land use by 2050 because population will reach 9 billion while agricultural productivity losses are expected due to overuse of lands. How can we feed the next generations in a manner that respects our finite natural resources? Managing our resources in a sustainable way have only begun for selected crops. Much remains to be done to increase food yield. Cropping practices capable of sustainable production need to be elaborated, especially in fragile ecosystems. Typical applications will include the improvement and use of genetic resources; crop management and diversification; diffusion of improved varieties; development of cropping systems; sustainable cropping systems for areas prone to environmental degradation; use of agro-ecological data for crop production forecasting; and networks for regional coordination, and data exchange. The impetus behind this book is to bring attention to a cropping system that bears direct relevance to sustainable agriculture and food security. “Underutilized” crops are found in numerous agricultural ecosystems and often survive mainly in marginal areas. It is timely to review their status because, in recent decades, scientific and economic interests have emerged which focus on lesser-known cultivated species. Underutilized crops have a great potential to alleviate hunger directly, through increasing food production in challenging environments where major crops are severely limited. “Global Perspectives on Underutilized Crops” is therefore topical and highlights the unmet agricultural challenges that we face today. This book is an important resource for students and researchers of crop science and agricultural policy makers.

Download or read book Language and Ecology in Southern and Eastern Arabia written by Janet C.E. Watson and published by Bloomsbury Publishing. This book was released on 2022-10-20 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regions of the world with greatest biodiversity are shown to exhibit greatest linguistic diversity, strongly suggesting that the relationship between language and ecology is both symbiotic and spatially and temporally determined. This volume examines the expressions of, and threats and challenges to, this relationship in southern and eastern Arabia. Exploring the ways in which indigenous languages reflect the close relationship between people and their natural environment, this book presents an overview of the key threats and challenges, and introduces the methodologies used to investigate them. Across the chapters, case studies are presented dealing with language, gesture and ecology, the significance of naming, the role of narratives in the language–ecology relationship, and conservation and revitalisation of bio-cultural diversity in Arabia. Taking a multidisciplinary view, this book argues for the central role that language plays in facing the challenges and threats to bio-cultural diversity, and presents methods for the study of the language–nature relationship that can be applied globally.

Download or read book Embryology of Flowering Plants Terminology and Concepts Vol 3 written by T B Batygina and published by CRC Press. This book was released on 2019-04-23 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant embryology, dealing with the regularities of initiation and the first stages of development of an organism, is now flourishing because of the overall progress being made in natural sciences. Such discoveries of the 20th century as production of plants from a single somatic cell, experimental haploidy, and parasexual hybridization were of general biological significance. The combined efforts of embryologists, geneticists and molecular biologists yielded the discovery of specific genes that control meiosis, egg cell development and early stages of embryogenesis. The tendency to synthesize data of embryology and genetics has become increasingly noticeable. It is connected with the fact that the majority of problems connected with morphogenesis, such as differentiation, specialization, the evaluation of features and the definition of the notionsgene and feature andgenotype and phenotype concern embryology and genetics (embryogenetics) in one way or another. Evolutionary embryology has given rise to a new approach to the study of problems of adaptation in plants. In connection with the problem of preserving biological diversity under conditions of ecological stress, special attention is paid to ecological embryology, revealing the critical periods in early ontogenesis and plasticity and tolerance of reproductive systems at the level of species and population. The study of variability of morphogenesis and phenotype in population (life cycle variations and the diversity of reproductive systems) is the most important point in the population embryology of plants.

Download or read book The Flowering Plants Handbook written by James W. Byng and published by Plant Gateway Ltd.. This book was released on 2014-10-16 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: This plant book aims to help identify flowering plants to genus and family level anywhere in the world. In 2014 there were very few available works which were both comprehensive and up-to-date for all the flowering plants families and genera of the world. The Flowering Plants Handbook is an easy to use identification guide to the worlds flowering plants designed for both specialists and non-specialists and from beginner to expert. The book contains descriptions of all currently recognised flowering plant families, morphological notes for 6656 genera (all current genera for 398/413 families) and over 3000 images and illustrations. Flowering plants can be identified using the book to family and much of the world's generic diversity in four 'easy' steps. Some plants will be identified correctly quickly, whilst others may require some retracing of steps and take a little more time. The advantage of this book is that it helps the user learn about the classification system and plant diversity during the identification process. This work was compiled and developed using the living, library and herbarium collections at the University of Aberdeen, Royal Botanic Gardens, Edinburgh and Royal Botanic Gardens, Kew.

Available in PDF, EPUB and Kindle. Book excerpt: Winner of the Marsh Book of the Year Award 2012 by theBritish Ecological Society. In A Resource-Based Habitat View for Conservation RogerDennis introduces a novel approach to the understanding of habitatsbased on resources and conditions required by organisms and theiraccess to them, a quantum shift from simplistic andineffectual notions of habitats as vegetation units or biotopes. Indrawing attention to what organisms actually use and need inlandscapes, it focuses on resource composition, structure andconnectedness, all of which describe habitat quality and underpinlandscape heterogeneity. This contrasts with the current bipolarview of landscapes made up of habitat patches and empty matrix butillustrates how such a metapopulation approach of isolatedpatchworks can grow by adopting the new habitat viewpoint. The book explores principles underlying this newdefinition of habitat, and the impact of habitat components onpopulations, species’ distributions, geographical ranges andrange changes, with a view to conserving resources in landscapesfor whole communities. It does this using the example ofbutterflies - the most alluring of insects, flagship organisms andkey indicators of environmental health - in the British Isles,where they have been studied most intensively. The book formsessential reading for students, researchers and practitioners inecology and conservation, particularly those concerned withmanaging sites and landscapes for wildlife.

Download or read book Ecology of Himalayan Treeline Ecotone written by S P Singh and published by Springer Nature. This book was released on 2023-02-21 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together comprehensive multi-disciplinary knowledge on diverse aspects of the Himalayan treeline ecotone which is considered one of the most sensitive ecosystems to climate change. The contents of this book are based on the results of extensive research and provide a holistic understanding of the treeline ecotone in Himalaya. The book will serve as an important reference manual and a textbook on treeline ecology. The book is unique in the sense that it provides an engaging account of almost all the aspects of the treeline ecotone, such as taxonomic, functional and phylogenetic species diversity, temperature lapse rates, tree phenology, water relations, and stress physiology, tree ring width chronology, and climate relationships and the role of treeline ecotone in human sustenance in the Indian Himalayan region The treelines in the Himalaya, being the highest in the Northern Hemisphere (up to 4900 m), are among the least investigated systems and hence this book is timely and fills all-important knowledge gaps vis-à-vis treeline shifts, physiognomic, structural, and functional changes in mountain landscapes and ecosystems, particularly under the changing climate This book, for the first time, summarizes evidence-based knowledge about various aspects of treeline ecotone in Himalaya that was largely generated through a well-coordinated a team science approach. The book will be of interest to ecologists, climatologists, dendrochronologists, foresters, plant physiologists and resource managers and policy planners for a better understanding of the organization and dynamics of this fragile ecosystem in relation to climate change and other anthropogenic stresses that are rampant in the Himalaya. The book lays a solid foundation for further investigation of the ecology and dynamics of the treeline ecotone in the Himalayas and provides a rationale for pursuing a team science approach for macroecological investigations.

Book excerpt: The new edition of Seeds contains new information on many topics discussed in the first edition, such as fruit/seed heteromorphism, breaking of physical dormancy and effects of inbreeding depression on germination. New topics have been added to each chapter, including dichotomous keys to types of seeds and kinds of dormancy; a hierarchical dormancy classification system; role of seed banks in restoration of plant communities; and seed germination in relation to parental effects, pollen competition, local adaption, climate change and karrikinolide in smoke from burning plants. The database for the world biogeography of seed dormancy has been expanded from 3,580 to about 13,600 species. New insights are presented on seed dormancy and germination ecology of species with specialized life cycles or habitat requirements such as orchids, parasitic, aquatics and halophytes. Information from various fields of science has been combined with seed dormancy data to increase our understanding of the evolutionary/phylogenetic origins and relationships of the various kinds of seed dormancy (and nondormancy) and the conditions under which each may have evolved. This comprehensive synthesis of information on the ecology, biogeography and evolution of seeds provides a thorough overview of whole-seed biology that will facilitate and help focus research efforts. Most wide-ranging and thorough account of whole-seed dormancy available Contains information on dormancy and germination of more than 14,000 species from all the continents – even the two angiosperm species native to the Antarctica continent Includes a taxonomic index so researchers can quickly find information on their study organism(s) and Provides a dichotomous key for the kinds of seed dormancy Topics range from fossil evidence of seed dormancy to molecular biology of seed dormancy Much attention is given to the evolution of kinds of seed dormancy Includes chapters on the basics of how to do seed dormancy studies; on special groups of plants, for example orchids, parasites, aquatics, halophytes; and one chapter devoted to soil seed banks Contains a revised, up-dated classification scheme of seed dormancy, including a formula for each kind of dormancy Detailed attention is given to physiological dormancy, the most common kind of dormancy on earth
