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 Plant Gene Silencing written by M.A. Matzke and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an up-to-date and comprehensive collection of reviews on various aspects of epigenetic gene silencing in plants. Research on this topic has undergone explosive growth during the past decade and has revealed novel features of gene regulation and plant defense responses that also apply to animals and fungi. Gene silencing is relevant for agricultural biotechnology because stable expression of transgenes is required for the successful commercialization of genetically engineered crops. The reviews have been written by distinguished authors who have made significant contributions to plant gene silencing research. This volume supersedes other books on gene silencing by focussing on plant systems, where many pioneering experiments have been performed, and by including the latest developments from top laboratories. The book is geared toward advanced students of genetics and plant sciences as well as applied and basic research scientists who work with transgenic organisms and epigenetic regulation of gene expression.

Download or read book Genetic Flux in Plants written by Barbara Hohn and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic material is in flux: this is one of the most exciting recent concepts in molecular biology. This volume of "Plant Gene Research" describes changes that occur in the genetic material of plants. It is worthwhile re membering that the first examples of unstable genomes were described for maize before DNA was known to be the genetic material. Now trans posable elements like the ones found in maize have been described in almost all organisms and have become incorporated into our thinking about genome structure. Flux in the plant genome is not restricted to transposable elements or to nuclear genes. Exchanges of genetic material have been demonstrated within organelle DNA, between organelle DNAs or between organelle and nuclear DNAs. Such exchanges may only occur over evolutionary times or may be a continuing process. Also the environment alters the plant genome. Stress, either viral, nutri tional or tissue-culture induced causes heritable changes in the genome. Infection with the crown gall bacterium Agrobacterium tumefaciens results in the transfer of bacterial DNA into the plant genome.

This book was released on 2017-01-28 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.

The book is "a concise and accurate narrative, that also manages to be interesting and personal...a splendid little book." Biotechnology states, "Because of the clarity with which it is written, this thin volume makes a major contribution to improving public understanding of genetic engineering's potential for enlarging the world's food supply...and can be profitably read by practically anyone interested in application of molecular biology to improvement of productivity in agriculture."
Download or read book Epigenetic Inheritance and Evolution written by Eva Jablonka and published by Oxford University Press, USA. This book was released on 1995 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Does the inheritance of acquired characteristics play a significant role in evolution? In this book, Eva Jablonka and Marion J. Lamb attempt to answer that question with an original, provocative exploration of the nature and origin of hereditary variations. Starting with a historical account of Lamarck's ideas and the reasons they have fallen in disrepute, the authors go on to challenge the prevailing assumption that all heritable variation is random and the result of variation in DNA base sequences. They also detail recent breakthroughs in our understanding of the molecular mechanisms underlying inheritance--including several pathways not envisioned by classical population genetics--and argue that these advances need to be more fully incorporated into mainstream evolutionary theory. Throughout, the book offers a new look at the evidence for and against the hereditability of environmentally induced changes, and addresses timely questions about the importance of non-Mendelian inheritance. A glossary and extensive list of references round out the book. Urging a reconsideration of the present DNA-centric view prevalent in the field, Epigentic Inheritance and Evolution will make fascinating and important reading for students and researchers in evolution, genetics, ecology, molecular biology, developmental biology, and the history and philosophy of science.
