Download or read book Somatic Embryogenesis in Woody Plants written by S. Mohan Jain and published by Springer Science & Business Media. This book was released on 2000-09-30 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid progress on somatic embryogenesis and its prospects for potential application to improving woody plants prompted us to edit this book initially in three volumes, and now an additional three more volumes. We were all convinced that such a treatise was needed and would be extremely useful to researchers and students. This volume 6 is dedicated to Prof. Harry Waris, Helsinki, Finland, who did pioneer work on somatic embryogenesis during the time when Prof. Steward and others were actively engaged in this area. His former student Prof. Liisa Simols, University of Helsinki, Finland, has written a dedication `Harry Waris, a pioneer in somatic embryogenesis' to her teacher Prof. Waris. This volume is divided into three sections and contains a total of 26 chapters. Section A comprises seven chapters covering topics such as: Historical insights into some contemporary problems in somatic embryogenesis (SE); Thin cell layer for somatic embryogenesis induction in woody trees; SE in tropical fruit and forest trees; SE in fruit and forest arid trees; Status of SE in Indian forest trees; SE research in fruit trees in India; Applications of SE for the improvement of tropical fruit trees. Section B comprises 15 chapters, dealing with: SE in oil palm, hazelnut (Corylus avellana L.), pistachio (Pistacia vera L.), Araucaria angustifolia, Quercus suber, Aspidosperma polyneuron, Acacia senegal, Simmondsia chiensis, Cupressus sempervirens, pecan (Carya illinoinensis), rattan (Calamus spp.), tamarillo (Cyphomandra betacea, longan (Dimocarpus longan Lor.), Aegle marmelos, and Euonymus europaeus. Section C comprises three chapters related to cryo-storage of citrus, conifers and rubber. All the chapters have been peer-reviewed and revised accordingly to improve the quality of the chapters. We are thankful to all: (a) contributory authors for their co-operation in submitting manuscripts in time, and (b) reviewers for spending their valuable time in reviewing the manuscripts.

This book was released on 2016-10-14 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: DNA can be extracted and sequenced from a diverse range of biological samples, providing a vast amount of information about evolution and ecology. The analysis of DNA sequences contributes to evolutionary biology at all levels, from dating the origin of the biological kingdoms to untangling family relationships. An Introduction to Molecular Evolution and Phylogenetics presents the fundamental concepts and intellectual tools you need to understand how the genome records information about evolutionary past and processes, how that information can be "read", and what kinds of questions we can use that information to answer. Starting with evolutionary principles, and illustrated throughout with biological examples, it is the perfect starting point on the journey to an understanding of the way molecular data is used in modern biology.

Download or read book Natural Products of Woody Plants written by John W. Rowe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood as found in trees and bushes was of primary importance to ancient humans in their struggle to control their environment. Subsequent evolution through the Bronze and Iron Ages up to our present technologically advanced society has hardly diminished the importance of wood. Today, its role as a source of paper products, furniture, building materials, and fuel is still of major significance. Wood consists of a mixture of polymers, often referred to as lignocellulose. The cellulose micro fibrils consist of an immensely strong, linear polymer of glucose. They are associated with smaller, more complex polymers composed of various sugars called hemicelluloses. These polysaccharides are embedded in an amorphous phenylpropane polymer, lignin, creating a remarkably strong com posite structure, the lignocellulosic cell wall. Wood also contains materials that are largely extraneous to this lignocellulosic cell wall. These extracellular substances can range from less than 1070 to about 35% of the dry weight of the wood, but the usual range is 2% -10%. Among these components are the mineral constituents, salts of calcium, potassium, sodium, and other metals, particularly those present in the soil where the tree is growing. Some of the extraneous components of wood are too insoluble to be ex tracted by inert solvents and remain to give extractive-free wood its color; very often these are high-molecular-weight polyphenolics.

Download or read book SUCCINITE FOSSILIZED RESIN REDISCOVERED written by Peter M. Barczak and published by Piotr Barczak. This book was released on 2022-10-03 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Baltic amber fascinates thousands of tourists who come to the Baltic Sea. Small children and their parents are eager to bury the sand while looking for precious resin. It is not easy to find, and every large piece of amber found in the “cucumber season” makes headlines. Another category of amber hunters are professionals. These are people who make a living from extracting amber of jewelry value, because each piece of fossilized resin has quite a lot of value. This group is quite hermetic, and the places and methods of extraction remain in the sphere of understatement and are shrouded in a certain mystery. The aforementioned group is particularly interested in the uniqueness of Baltic amber, created by “ancient” rivers, that was already traded by Persians, Vikings and Mycenaeans. From this group, wonderful jewelry products are created. In this book, however, I deal with another aspect of Baltic amber. The initial idea was to analyze the knowledge of this fossilized resin in various aspects. The difficulty in getting to know amber is related to the multidimensionality of the issue. The problem is that science likes to specialize to be precise. This, however, limits knowledge of the issue of amber. If we deal with the question of the formation of the resin, we touch upon issues in the field of geology. This field is enough to fill many years of research and work of a scientist. You can look back a hundred thousand years ago, or into the past millions of years or tens of millions of years, which means that we delve into such vast knowledge that the life of one person may be too short to study the issue well.Then, what do we find in amber? Insects. Thousands of insects. Every geological epoch, each geological era means different families and different species of preserved insects, all of which are to be obtained, dissected, and described in scientific articles. Again, work for a lifetime, infinitely long, because we reach millions of years into the past, and not even in one specific place on the planet – we need to look through the entire planet, because it has been changing over millions of years. What about the plants? After all, they created succinite at different stages of development. What were they like? Are those plants we know today the same ones that existed millions of years ago? Further, some species have become extinct, some have evolved, some grow today in China and others in New Zealand or New Caledonia. Then there is chemistry, the compounds found in amber… Terpenes have already been counted; 40,000. And they can be found in amber. Maybe not in that number, but – since amber was found in peat, brown coal, surrounded by minerals, sediments, and rocks – it could have absorbed the catalog of chemical compounds occurring in the world of plants, trees and shrubs, and also essential oils.

Download or read book Life in Amber written by George O. Poinar and published by Stanford University Press. This book was released on 1992 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Amber is a semi-precious gem that is formed over eons by natural forces out of the resin of trees. Human fascination with amber dates back to prehistoric times, when it was probably considered to have magical powers and was used for adornment and trade. Amber amulets and beads dating from 35,000 to 1,800 B.C. have been found, and where they have been found (for example in graves hundreds of miles from their chemically determined origins) has often helped to establish ancient trade routes." "The preservative qualities of plant resins were well known by the ancients. The Egyptians used resins to embalm their dead, and the Greeks used them to preserve their wine. Amber often preserved fossils, frequently in a pristine state, of all kinds of animal and plant organisms that made contact with the sticky substance and became trapped in it. These fossils include such fragile organisms as nematodes and mushrooms that ordinarily are not preserved under normal processes of fossilization, as well as larger organisms like scorpions and lizards, and the fossils are preserved in their full three-dimensional form, complete with minute details of scales, mouth parts, antennae, and hairs. It has even been suggested that viable DNA may persist in some amber-trapped organisms." "This book is a compendium of all that we know about life found in amber. It surveys all life forms, from microbes to vertebrates and plants, that have been reported from amber deposits throughout the world, beginning with the earliest pieces dating from some 300 million years ago. It also describes the formation of amber and the location, geological history, and early exploration of the major world amber deposits, including those still being worked today." "The book also provides practical information on how to determine fake amber containing present-day forms of life. It can serve as a beginning for tracing the geological history of a particular group of animals or plants or even reconstructing ancient paleoenvironments, and because amber fossils are preserved so completely, in a transparent medium, they can be intimately compared with related living species. Finally, the book discusses what amber fossils can tell us about evolution and speciation, cellular preservation, and paleosymbiosis." "The book is illustrated with 37 color photographs, 154 black-and-white photographs and drawings, and 8 maps."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book Plants in Mesozoic Time written by Carole T. Gee and published by Indiana University Press. This book was released on 2010-07-16 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants in Mesozoic Time showcases the latest research of broad botanical and paleontological interest from the world's experts on Mesozoic plant life. Each chapter covers a special aspect of a particular plant group -- ranging from horsetails to ginkgophytes, from cycads to conifers -- and relates it to key innovations in structure, phylogenetic relationships, the Mesozoic flora, or to animals such as plant-eating dinosaurs. The book's geographic scope ranges from Antarctica and Argentina to the western interior of North America, with studies on the reconstruction of the Late Jurassic vegetation of the Morrison Formation and on fossil angiosperm lianas from Late Cretaceous deposits in Utah and New Mexico. The volume also includes cutting-edge studies on the evolutionary developmental biology ("evo-devo") of Mesozoic forests, the phylogenetic analysis of the still enigmatic bennettitaleans, and the genetic developmental controls of the oldest flowers in the fossil record.

Download or read book Seeds written by Carol C. Baskin and published by Elsevier. This book was released on 2014-02-20 with total page 1600 pages. Available in PDF, EPUB and Kindle. 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
