Download or read book Satellite DNA written by Thengiz Beridze and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The organization of genomes in higher organisms has been studied extensively in recent years. With current achievements in gene engineering, it seems quite realistic that they will be specifically modified in the nearest future to produce new, economi cally valuable forms of animals and plants. The success of these experiments will depend greatly on the level of our knowledge of the structural features of plant and animal DNAs. Comparative studies of DNA from different organisms began with discovery of its genetic significance in the late 1950's. A few years later it was found that nuclear DNA, the main storage of genetic information,~an consist of several fractions differ ing in some physical and chemical properties. Along with the "major" DNA, bearing the main load during the genotype functioning, the so-called satellite DNAs were discovered. T. G. Beridze, the author of this book, is one of the pioneers in the study of these extraordinary DNAs. The results of his experiments with plant satellite DNAs have essentially influenced the formation of our current ideas on their structure and prop erties.

Download or read book Transport in Plants I written by M.H. Zimmermann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol ogy more than three decades ago, biology could still be conveniently subdivided into classical areas. Even within plant physiology, subdivisions were not too difficult to make, and general principles could be covered sufficiently in the two introductory volumes of the Encyclopedia on the physical and chemical basis of cell biology. But the situation changed rapidly even during the 12-year publication period of the Encyclopedia (1955-1967). The new molecular direction of genetics and structural research on biopolymers had an integrating effect on all other biological fields, including plant physiology, and it became increasingly difficult to keep previously distinct areas separated. RUHLAND'S overall plan included 18 volumes and about 22,000 pages. It covered the entire field of plant physiology, in most cases from the very beginning. But, as each volume appeared, it was clear that its content would soon be outdated.

Download or read book Microbial Taxonomy Phylogeny and Biodiversity written by Jesús L. Romalde and published by Frontiers Media SA. This book was released on 2019-12-31 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The great diversity of microbial life is the remaining major reservoir of unknown biological diversity on earth. To understand this vast, but largely unperceived diversity with its untapped genetic, enzymatic and industrial potential, microbial systematics is undergoing a revolutionary change in its approach to describe novel taxa based on genomic/envirogenomic information. The characterization of an organism is no longer bounded by methodological barriers, and it is now possible to fully sequence the whole genome of a strain to study individual genes, or to examine the genetic information by using different techniques. In fact, application of genomics is helping not only to provide a better understanding of the boundaries of genera and higher levels of classification, but also to refine our definition of the species concept. In addition, increased understanding of phylogeny is allowing to predict the genetic potential of microorganisms for biotechnological applications and adaptation to environmental changes. The present Research Topic on “Microbial Taxonomy, Phylogeny and Biodiversity” compiles a collection of papers covering the use of genomic sequence data in microbial taxonomy and systematics, including evolutionary relatedness of microorganisms; application of comparative genomics in systematic studies; or metagenomic approaches for biodiversity studies. We hope that this eBook incentives and encourages researchers for future discussions on microbial taxonomy and phylogenetics.

Download or read book The Soils of Mexico written by Pavel Krasilnikov and published by Springer Science & Business Media. This book was released on 2013-02-12 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexico is an extensive country with an extremely complex mosaic of landscapes. The soils of Mexico have still not been completely studied, and there are few publications available on this subject. This book provides a state-of-the-art view on Mexican soils, their geographical distribution, their use and degradation. This is a first attempt to give a systematized characteristic of the soil resources of Mexico. Land resources of the second-biggest economy in Latin America are critical for its sustainable development, and a demand for adequate soil information is high. The information contained within can be used for any soil-related research done in Mexico and in neighboring countries. The book includes detailed characteristics of soils of all the physiographic regions of Mexico with maps, photos and explanatory schemes. The book is based on the experiences of the authors in research and soil survey, as well as on the existent, mainly ‘grey’ literature on Mexican soils. The book is recommended for researchers and university readers, students of all levels and decision-makers, working in the area of soil science, environmental issues, Earth sciences, land management and nature conservation.

Download or read book Saving Nature s Legacy written by Reed F. Noss and published by Island Press. This book was released on 1994-04-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by two leading conservation biologists, Saving Nature's Legacy is a thorough and readable introduction to issues of land management and conservation biology. It presents a broad, land-based approach to biodiversity conservation in the United States, with the authors succinctly translating principles, techniques, and findings of the ecological sciences into an accessible and practical plan for action. After laying the groundwork for biodiversity conservation -- what biodiversity is, why it is important, its status in North America -- Noss and Cooperrider consider the strengths and limitations of past and current approaches to land management. They then present the framework for a bold new strategy, with explicit guidelines on: inventorying biodiversity selecting areas for protection designing regional and continental reserve networks establishing monitoring programs setting priorities for getting the job done Throughout the volume, the authors provide in-depth assessments of what must be done to protect and restore the full spectrum of native biodiversity to the North American continent.
