Chapters are also devoted to haploid embryogenesis, asexual embryogenesis in nature, zygotic embryogenesis, and zygotic embryo culture. Detailed tables summarizing successful somatic embryogenesis in all vascular plants are also included. This book, therefore, brings together previously scattered information to provide an indispensable reference book for both active researchers, graduate students and anyone interested in this aspect of tissue culture technology and plant development.
Download or read book Tree Breeding Principles and Strategies written by G. Namkoong and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has become apparent, during discussions with students and colleagues in forest genetics, that a universal concern is the achievement of diverse goals of forestry from fiber production in industrial as well as farm forests to conserving forest ecosystems. Although we generally have several breeding methods available and several species to breed, we seek to satisfy multiple-use goals on diverse sites by management techniques that at best can only partially control edaphic environmental variation. The dominant approach, which was agriculturally motivated, has involved inten sive effort with complicated breeding plans on single species for uniform adaptability and single-product plantations. However, this is obviously neither the only, nor necessarily the best, solution for the genetic management of tree species, and thus our intent in this volume is to develop ways to achieve multiple objectives in tree breeding. We include an array of breeding plans from simple iterated designs to sets of multiple populations capable of using gene actions for different traits in different environments for uncertain futures. The presentation is organized around the development of breeding from single-to multiple-option plans, from single to multiple traits, from single to mUltiple environ ments, and from single to multiple populations. However, it is not a complete "How To" book, and includes neither exercises nor instructions on data handling. It also does not include discussion of all modes of reproduction and inheritance encountered in plants.

Download or read book Somatic Embryogenesis in Ornamentals and Its Applications written by Abdul Mujib and published by Springer. This book was released on 2015-12-22 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Somatic embryogenesis (SE) is a unique process by means of which a vegetative/somatic plant cell transforms into an embryo. This in vitro embryogeny has immense fundamental and practical applications. The SE process is complex and is controlled by a variety of external and internal triggers. This book compiles the latest advances in embryogenesis research on ornamentals and discusses the importance of embryogenic cultures/tissues in raising transgenic crops. The technique of cryopreservation in the protection of ornamental genetic resources is discussed using embryogenic culture/embryo as the tissue of choice, and the respective roles of the genotype, plant growth regulator, environment and other regulating factors in embryogenesis are discussed. The book also focuses on comparative biochemical and physiological differences during the acquisition and development of embryos. The importance of plant proteome and functional genomics as a source of markers is highlighted, and special attention is paid to genes / gene homologues (SERC) in characterizing embryogenesis. Lastly, the book examines the involvement of auxin polar transport and other molecular networks regulating gene expression.

This book was released on 2013-03-14 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: While working in the laboratory of Professor Dr. Jacob Reinert at the Freie Universitat Berlin (1974-1976), I had the opportunity to become deeply involved in studying the intricacies of the fascinating phenomenon of somatic embryogenesis in plant cells and protoplasts. In numerous stimu lating discussions with Professor Reinert on this subject, I was fully convinced that somatic embryogenesis would become one of the most important areas of study, not only regarding basic and fundamental aspects, but also for its application in crop improvement. During the last decade, we have witnessed tremendous interest and achievements in the use of somatic embryos for the production of synthetic seeds, for micro propagation, genetic transformation, cryopreservation, and conservation of germplasm. The en masse production of somatic embryos in the bioreactors has facilitated some of these studies. Somatic embryos have now been induced in more than 300 plant species belonging to a wide range offamilies. It was therefore felt that a compilation ofliterature/state of the art on this subject was necessary. Thus, two volumes on Somatic Embryo genesis and Synthetic Seed have been compiled, which contain 65 chapters contributed by International experts. Somatic Embryogenesis and Synthetic Seed I comprises 31 chapters, arranged in 3 sections: Section I Commitment of the cell to somatic embryogenesis; early events; anatomy; molecular basis; gene expression; role of polyamines; machine vision analysis of somatic embryos. Section II Applications of somatic embryos; technology of synthetic seed; fluid drilling; micropropagation; genetic transfor mation through somatic embryos; cryopreservation.
Download or read book Maternal Control of Development in Vertebrates written by Florence Louise Marlow and published by Morgan & Claypool Publishers. This book was released on 2010 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eggs of all animals contain mRNAs and proteins that are supplied to or deposited in the egg as it develops during oogenesis. These maternal gene products regulate all aspects of oocyte development, and an embryo fully relies on these maternal gene products for all aspects of its early development, including fertilization, transitions between meiotic and mitotic cell cycles, and activation of its own genome. Given the diverse processes required to produce a developmentally competent egg and embryo, it is not surprising that maternal gene products are not only essential for normal embryonic development but also for fertility. This review provides an overview of fundamental aspects of oocyte and early embryonic development and the interference and genetic approaches that have provided access to maternally regulated aspects of vertebrate development. Some of the pathways and molecules highlighted in this review, in particular, Bmps, Wnts, small GTPases, cytoskeletal components, and cell cycle regulators, are well known and are essential regulators of multiple aspects of animal development, including oogenesis, early embryogenesis, organogenesis, and reproductive fitness of the adult animal. Specific examples of developmental processes under maternal control and the essential proteins will be explored in each chapter, and where known conserved aspects or divergent roles for these maternal regulators of early vertebrate development will be discussed throughout this review.

Download or read book Human Genome Editing written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-08-13 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genome editing is a powerful new tool for making precise alterations to an organism's genetic material. Recent scientific advances have made genome editing more efficient, precise, and flexible than ever before. These advances have spurred an explosion of interest from around the globe in the possible ways in which genome editing can improve human health. The speed at which these technologies are being developed and applied has led many policymakers and stakeholders to express concern about whether appropriate systems are in place to govern these technologies and how and when the public should be engaged in these decisions. Human Genome Editing considers important questions about the human application of genome editing including: balancing potential benefits with unintended risks, governing the use of genome editing, incorporating societal values into clinical applications and policy decisions, and respecting the inevitable differences across nations and cultures that will shape how and whether to use these new technologies. This report proposes criteria for heritable germline editing, provides conclusions on the crucial need for public education and engagement, and presents 7 general principles for the governance of human genome editing.
Download or read book Epigenetics in Plants of Agronomic Importance Fundamentals and Applications written by Raúl Alvarez-Venegas and published by Springer. This book was released on 2014-07-22 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decades, chromatin remodelling has emerged as an important regulator of gene expression and plant defense. This book provides a detailed understanding of the epigenetic mechanisms involved in plants of agronomic importance. The information presented here is significant because it is expected to provide the knowledge needed to develop in the future treatments to manipulate and selectively activate/inhibit proteins and metabolic pathways to counter pathogens, to treat important diseases and to increase crop productivity. New approaches of this kind and the development of new technologies will certainly increase our knowledge of currently known post-translational modifications and facilitate the understanding of their roles in, for example, host-pathogen interactions and crop productivity. Furthermore, we provide important insight on how the plant epigenome changes in response to developmental or environmental stimuli, how chromatin modifications are established and maintained, to which degree they are used throughout the genome, and how chromatin modifications influence each another.
