Download or read book Polyploidy and Genome Evolution written by Pamela Soltis and published by Springer Science & Business Media. This book was released on 2012-10-03 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyploidy – whole-genome duplication (WGD) – is a fundamental driver of biodiversity with significant consequences for genome structure, organization, and evolution. Once considered a speciation process common only in plants, polyploidy is now recognized to have played a major role in the structure, gene content, and evolution of most eukaryotic genomes. In fact, the diversity of eukaryotes seems closely tied to multiple WGDs. Polyploidy generates new genomic interactions – initially resulting in “genomic and transcriptomic shock” – that must be resolved in a new polyploid lineage. This process essentially acts as a “reset” button, resulting in genomic changes that may ultimately promote adaptive speciation. This book brings together for the first time the conceptual and theoretical underpinnings of polyploid genome evolution with syntheses of the patterns and processes of genome evolution in diverse polyploid groups. Because polyploidy is most common and best studied in plants, the book emphasizes plant models, but recent studies of vertebrates and fungi are providing fresh perspectives on factors that allow polyploid speciation and shape polyploid genomes. The emerging paradigm is that polyploidy – through alterations in genome structure and gene regulation – generates genetic and phenotypic novelty that manifests itself at the chromosomal, physiological, and organismal levels, with long-term ecological and evolutionary consequences.

Download or read book Somaclonal Variation and Induced Mutations in Crop Improvement written by S.M. Jain and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic variability is an important parameter for plant breeders in any con ventional crop improvement programme. Very often the desired variation is un available in the right combination, or simply does not exist at all. However, plant breeders have successfully recombined the desired genes from cultivated crop gerrnplasm and related wild species by sexual hybridization, and have been able to develop new cultivars with desirable agronomie traits, such as high yield, disease, pest, and drought resistance. So far, conventional breeding methods have managed to feed the world's ever-growing population. Continued population growth, no further scope of expanding arable land, soil degradation, environ mental pollution and global warrning are causes of concern to plant biologists and planners. Plant breeders are under continuous pressure to improve and develop new cultivars for sustainable food production. However, it takes several years to develop a new cultivar. Therefore, they have to look for new technologies, which could be combined with conventional methods to create more genetic variability, and reduce the time in developing new cultivars, with early-maturity, and improved yield. The first report on induced mutation of a gene by HJ. Muller in 1927 was a major mi1estone in enhancing variation, and also indicated the potential applica tions of mutagenesis in plant improvement. Radiation sources, such as X-rays, gamma rays and fast neutrons, and chemical mutagens (e. g. , ethyl methane sulphonate) have been widely used to induce mutations.

Download or read book Molecular Plant Taxonomy written by Pascale Besse and published by Humana. This book was released on 2014-01-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant taxonomy is an ancient discipline facing new challenges with the current availability of a vast array of molecular approaches which allow reliable genealogy-based classifications. Although the primary focus of plant taxonomy is on the delimitation of species, molecular approaches also provide a better understanding of evolutionary processes, a particularly important issue for some taxonomic complex groups. Molecular Plant Taxonomy: Methods and Protocols describes laboratory protocols based on the use of nucleic acids and chromosomes for plant taxonomy, as well as guidelines for phylogenetic analysis of molecular data. Experts in the field also contribute review and application chapters that will encourage the reader to develop an integrative taxonomy approach, combining nucleic acid and cytogenetic data together with other crucial information (taxonomy, morphology, anatomy, ecology, reproductive biology, biogeography, paleobotany), which will help not only to best circumvent species delimitation but also to resolve the evolutionary processes in play. Written in the successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Molecular Plant Taxonomy: Methods and Protocols seeks to provide conceptual as well as technical guidelines to plant taxonomists and geneticists.

Download or read book Diagnostics in Plant Breeding written by Thomas Lübberstedt and published by Springer Science & Business Media. This book was released on 2013-02-28 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Diagnostics in Plant Breeding” is systematically organizing cutting-edge research reviews on the development and application of molecular tools for the prediction of plant performance. Given its significance for mankind and the available research resources, medical sciences are leading the area of molecular diagnostics, where DNA-based risk assessments for various diseases and biomarkers to determine their onset become increasingly available. So far, most research in plant genomics has been directed towards understanding the molecular basis of biological processes or phenotypic traits. From a plant breeding perspective, however, the main interest is in predicting optimal genotypes based on molecular information for more time- and cost-efficient breeding schemes. It is anticipated that progress in plant genomics and in particular sequence technology made recently will shift the focus from “explanatory” to “predictive” in crop science. This book assembles chapters on all areas relevant to development and application of predictive molecular tools in plant breeding by leading authorties in the respective areas.

Download or read book Orchid Propagation From Laboratories to Greenhouses Methods and Protocols written by Yung-I Lee and published by Humana Press. This book was released on 2018-05-27 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The orchid family is one of the largest families of flowering plants known for their beauty and economic importance. This work provides information in key areas of research that are important to both scientists and commercial growers alike. The main purposes of this book are to provide key practical areas of research, such as, germination, micropropagation, traditional and current techniques related to plant improvement; document methods that ensure survival of plants from laboratories to greenhouses; promote communication between scientists and growers, so that their combined expertise on these areas will lead to the successful growth of orchids in their natural habitats or commercial greenhouses. This book can serve as reference for laymen with an interest in orchid growing.This book is divided into 5 parts. The first part emphasizes propagation methods using seeds and related techniques that are important to plant conservation and improvement. Successes in asymbiotic and symbiotic seed germination are keys to orchid conservation and their propagation. The second part summarizes micropropagation methods, common media, and newer methods of micropropagation such as the bioreactor culture procedures. The third part focuses on techniques related to the manipulation of explants in an in vitro environment. The fourth part covers cell biological methods and transformation techniques. Since the successes in a laboratory setting do not guarantee plant survival and propagation in greenhouses and in the natural environment, it discusses greenhouse propagation techniques that are essential to the survival of plants generated from a laboratory setting. The fifth part showcases recent successes on orchid propagation by documenting sample publications and how to present orchids in an artistic fashion for one’s enjoyment.

Download or read book Integrating Conventional and Chinese Medicine in Cancer Care written by Tai Lahans and published by Elsevier Health Sciences. This book was released on 2007-06-05 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new clinical resource clearly explains how to approach integrated care in a way that combines Chinese herbal medicine with Western medicine to enhance and improve medical care for patients with cancer - without undermining or negatively impacting patients' medical treatment. Each chapter covers a different type of cancer, first introducing the conventional medical understanding of that cancer including its etiology, diagnosis, and treatment according to staging and type. The chapter then covers that cancer from the perspective of Oriental medicine. Case studies illustrate the integration of treatment for each cancer type, raising important issues and considerations associated with specific cancers and treatments. Formulas are presented within the context of conventional treatment, intended to enhance the effectiveness of treatment and/or treat side effects without undermining the treatment's function. Each formula is followed by a discussion of how and why the herbs are used, including classical Chinese theory and relevant pharmaceutical studies. Staging and the age and performance status of various patients is used as a means by which to explain how formulas are changed. Case studies explore issues related to the integration of treatment for each type of cancer.
