Book Synopsis Distant Hybridization of Crop Plants by : G. Kalloo
Download or read book Distant Hybridization of Crop Plants written by G. Kalloo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild taxa are invaluable sources of resistance to diseases, insects/ pests, nematodes, temperature extremes, salinity and alkalinity stresses, and also of nutritional quality; adaptation; genetic diversity and new species. Utilization of wild relatives of a crop depends largely upon its crossability relations with cultivated varieties. Sev eral wild species are not crossable with the commercial cultivars due to various isolation barriers. Furthermore, in a few cases, hybridiza tion is possible only in one direction and reciprocal crosses are not successful, thus depriving the utilization of desired cytoplasm of many species. However, techniques have been developed to over come many barriers and hybrid plants are produced. New crop species have been developed by overcoming the F 1 sterility and producing amphidiploids and such crops are commercially being grown in the field. The segregation pattern ofF 1 hybrids produced by distant hybridization in segregating generations are different from the intervarietal hybrids. In former cases, generally, unidirectional segregation takes place in early generations and accordingly, selec tion procedures are adopted. In most of the cases, backcross or modified backcross methods have been followed to utilize wild species, and thus numerous types of resistance and other economical attributes have been transferred in the recurrent parents. Protoplast fusion has been amply demonstrated in a number of cases where sexual hybridization was not possible and, as a result, hybrids have been produced.

Book Synopsis Pollination Mechanisms, Reproduction and Plant Breeding by : R. Frankel
Download or read book Pollination Mechanisms, Reproduction and Plant Breeding written by R. Frankel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: view than its own proper males should fecundate each blossom." ANDREW KNIGHT Philosophical Transactions, 1799 Pollination mechanisms and reproduction have a decisive bearing upon rational procedures in plant breeding and crop production. This book intends to furnish' under one cover an integrated botanical, genetical and breeding-methodologi cal treatment of the reproductive biology of spermatophytes mainly angiosperms; it is based on an advanced topical course in plant breeding taught at the Hebrew University of Jerusa lem. We have tried to present a coverage which is concise, but as comprehensive as possible, of the pollination mechanism and modes of reproduction of higher plants, and to illustrate topics, whenever practicable, by examples from cultivated plants. Nevertheless, some relevant publications may have escaped our attention or may not be mentioned because of various limitations. The book is organized into three parts. The first part starts with an evaluation of the significance of the different pollination mechanisms for plant breeding and crop produc tion, describes modes of reproduction in higher plants and discusses ecology and dynamics of pollination. The second part is devoted to crops propagated by self pollination and describes specific breeding procedures for such crops. The third part details sexual reproduction in higher plants and handles three mechanisms involved in the prevention of self pollination and their utilization in plant breeding: sex expres sion, incompatibility, and male sterility.
Download or read book Heterosis written by R. Frankel and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: When trying to solicit authors for this book it became apparent that the causal factors for heterosis at the physiological and biochemical level are today almost as obscure as they were 30 years ago. Though biometrical-genetical analyses point to dispersion of complementary genes - not overdominance - as the major cause of the phenomenon, plant breeders' experience still suggests a cautious, pragmatic approach to the dominance-overdominance controversy in breeding hybrid cultivars. Thus we are faced with a striking discordance between our limited comprehension of the causal factors and mechanism of heter osis on the one hand, and the extensive agricultural practice of utiliza tion of hybrid vigor on the other. Such utilization is the result of the economic value of hybrid combinations displaying superior yields and qualities as well as stability of performance, of benefits derived in breeding programs, and of the enhanced varietal protection of proprietary rights. No comprehensive and critical analysis of the phenomenon of heterosis in economic plants has been published for the last three decades since the now classical book Heterosis, edited by J . W. Gowen (Iowa State College Press, Ames, Iowa, 1952). The present book attempts to fill the gap and to assess the status of our present knowl edge of the concept, the basis, the extent, and the application of heterosis in economic plants.
Book Synopsis Recurrent Implantation Failure by : Efstratios M. Kolibianakis
Download or read book Recurrent Implantation Failure written by Efstratios M. Kolibianakis and published by CRC Press. This book was released on 2019-07-30 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Implantation is a complex phenomenon, still not thoroughly understood, involving the embryo and the endometrium. Successful implantation is considered to stem from an efficient combination of various embryo and/or maternal factors. Repeated failure of any of these factors or of their combination might decrease the chance of implantation and eventually lead to recurrent implantation failure. Despite technological advances, only about a quarter of In Vitro Fertilization procedures will result in live birth, leading many couples to experience multiple failures. This text from international experts explores the various factors at play and offers a helpful summary of the state of knowledge to help guide clinicians in their management of this complex and important problem. Contents: What is Recurrent Implantation Failure? * The psychosocial aspects of recurrent implantation failure * The role of life-style factors in RIF * Endocrine causes of recurrent implantation failure * Congenital uterine anomalies and recurrent implantation failure * Immunological causes of recurrent implantation failure * Acquired uterine conditions, reproductive surgery, and RIF? * Thrombophilia: diagnosis and management in women with recurrent implantation failure * Andrological causes of RIF * Diagnostic evaluation of RIF? (Modalities and algorithm) * Optimizing embryo culture for RIF? * Optimizing endometrial receptivity for patients with recurrent implantation failure: The role of progesterone on the day of triggering final oocyte maturation * Is there a role of follicular phase LH and E2 on the day of triggering final oocyte maturation for embryo implantation? * Manipulating the endometrium: Can RIF be managed by inducing endometrial inflammation or by the use of novel research therapies * The embryo in RIF: Genetic selection and strategies for improving its implantation potential * Is oocyte donation efficient in patients with RIF? * Sperm donation and RIF? * Optimizing embryo transfer technique for RIF management * Proposed management of patients with recurrent implantation failure and directions for future research * When should patients abandon treatment?
Book Synopsis Tree Breeding: Principles and Strategies by : G. Namkoong
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.
Book Synopsis Incompatibility in Angiosperms by : D. de Nettancourt
Download or read book Incompatibility in Angiosperms written by D. de Nettancourt and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attempting to collect, sort out, comment on and summarize from available literature the relevant information dealing with a specific problem is always a difficult task which necessarily involves sub jective choices and implies a considerable risk of errors and omis sions. The difficulty is increased when, as in the case of incompati bility in angiosperms, the subject to be treated traces its history to preDarwinian times and reflects the total sum of numerous in vestigations dealing with widely different disciplines, such as ge netics, cytology, biochemistry, systematics and physiology, which no single reviewer may pretend to master sufficiently to avoid completely the possibility of misinterpretation. Furthermore, the complexity of the task is further augmented by the fact that the student of incompatibility, confronted as he or she is with still poorly understood phenomena of genetic control and molecular recognition, often tends to be speculative and, in some instances, over-imaginative at the time of fitting research observations and experimental data into appropriate models, schemes and hypo theses. The compensation for such a state of affair is, however, a strong one and lies in the remarkable willingness and readiness of "in compatibilists" to cooperate, and to provide information, ex planations and illustrations to anyone attempting to penetrate into their universe of research and of reflection.
Book Synopsis Evolution and Function of Heterostyly by : Spencer C.H. Barrett
Download or read book Evolution and Function of Heterostyly written by Spencer C.H. Barrett and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: A century of research on heterostylous plants has passed since the publication of Charles Darwin's book "The Different Forms of Flowers on Plants of the Same Species" in 1877 summarizing his extensive observations and experiments on these complex breeding systems involving genetic polymorphisms of floral sex organs. Since then heterostylous plants have provided a rich source of material for evolutionary biologists and today they represent one of the classic research paradigms for approaches to the study of evolution and adaptation. The present book is the first modern and comprehensive accont of the subject. In 10 chapters it is concerned with the evolution, genetics, development, morphology, and adaptive significance of heterostyly. Broad syntheses of research on heterostyly as well as new theoretical ideas and experimental data are included.
Book Synopsis Gene Interactions in Development by : L. I. Korochkin
Download or read book Gene Interactions in Development written by L. I. Korochkin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Russian edition of this book was published in 1975 many new research works have appeared which have made necessary some additions for the English edition, to reflect progress in molecular developmental genetics. Recent important findings in this field have brought about essential corrections to the concept of genetic regulation of the process of cell differentiation. The discovery of the mosaic structure of a gene prompted the re evaluation of our considerations about the regulation of gene activity in eukaryotes, and the data about transcriptional events during ontogenesis are of great importance as well. Formerly it was generally accepted that a derepression of genes was responsible for cell differentiation in the process of develop ment. Recently three important conclusions have been derived (Davidson and Britten, 1979) which help to pose the problem in a new way: 1) Only a small part of single copy sequences of DNA is represented in nuclear RNA of a given type of cell or tissue: 10% to 20% in sea urchin embryos, 11 % in rat liver, 4% to 6% in Drosophila cell culture, etc. Since only about 10% of single copy sequences represent the structural genes (Davidson and Britten, 1973), transcription of almost the whole set of structural genes occurs.

Book Synopsis Genetic Improvement of Tomato by : G. Kalloo
Download or read book Genetic Improvement of Tomato written by G. Kalloo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: The esculent Lycopersicon esculentum, long thought to be poisonous, has become a major U. S. food crop and source of vitamins and minerals, thanks largely to genetic modification and new production technology Rick (1978) Tomato (Lycopersicon esculentum Mill. ) is one of the most important solana ceous vegetable crops grown worldwide under outdoor and indoor conditions. It has become an important commercial crop so far as the area, production, industrial values and its contribution to human nutrition is concerned. During the past few decades tremendous developments have contributed to the knowledge and understanding of various areas of genetics, breeding and biotechnology and voluminous literature has been generated. The purpose of preparing this monograph is to give a comprehensive up-to-date treatment to the various aspects of genetic improvement of tomato. The emphasis has been placed on cytology, classical and molecular genetics, reproductive biology, germplasm resources, hybrid seed production, use of wild taxa, selection/ breeding methods, breeding for abiotic and biotic stresses, processing and quality breeding, improvement for mechanical harvesting, and biotechnology: tissue culture, protoplast fusion, and genetic transformation. These topics are presented in 22 different chapters. However, a few aspects have been discussed in more than one chapter. For example, seed production is treated in chapters 1, 4 and 8; molecular biology/genetic engineering in chapters 3 and 22 and heterosis in chapters 8 and 16.

Book Synopsis Meiotic Configurations by : J. Sybenga
Download or read book Meiotic Configurations written by J. Sybenga and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of the monographs is to foster effective intra- and interdisciplinary communication between geneticists, and plant and animal breeders. This is to be achieved by publishing authoritative up-to-date texts; concise, but at the same time comprehensive, monographs, and multiauthor volumes on theoretical and applied genetics. The following broad fields of genetics and breeding are within the scope of the series: Evolutionary genetics Developmental genetics Population genetics Biochemical genetics Ecological genetics Somatic cell genetics Biometrical genetics Agricultural genetics Cytogenetics Mutation breeding Radiation genetics Breeding methodology Acceptable subjects for the Monographs on Theoretical and Applied Genetics are basic and applied aspects of genetic variation; genetic resources; genetic exchange and reproduction; mutagenesis; genotype-environment interaction; gene structure, regulation, action, expression and interaction; chromosomal and extrachromosomal inheritance of economic traits, and genetic models and simulations. September 1975 The Editors Preface Meiotic configurations are looked at from a special point of view in this book: the extraction from them of the maximal amount of quantitative information of genetic interest. Although this requires a certain understanding of their origin and consequences, much of what is known about chromosomes and their for mation into the special structures collected under the rather indiscriminate term I "configuration", is not considered relevant for this purpose, and simply neglected.
