Available in PDF, EPUB and Kindle. Book excerpt: Most forest tree species were considered recalcitrant a decade ago, but now with the improved in vitro techniques some progress has been made towards culture-of tree species. Micro propagation has been achieved from the juvenile tissues of a number of forest tree species. On the other hand, tissues from most mature trees are still very difficult to grow and differen tiate in vitro. Nevertheless, there has been slow but steady progress in the application of tissue culture technology for culture of tissues, organs, cells and protoplasts of tree species. As compared to most agricultural crops, and herbaceous plant species, trees are a different lot. They have long gene ration cycles. They are highly heterozygous and have a large reservoir of genetic variability. Because of this genetic variability, their response in vitro is also variable. On a single medium, the response of tissues from different trees (genotypes) of a single species may be quite different: some responding by induction of growth and differentiation, while others showing minimal or no growth at all. That makes the somatic cell genetics of woody plants somewhat difficult, but at the same time interesting.

This book was released on 2005-05-23 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: World population is increasing at an alarming rate and this has resulted in increasing tremendously the demand for tree products such as wood for construction materials, fuel and paper, fruits, oils and medicines etc. This has put immense pressure on the world’s supplies of trees and raw material to industry and will continue to do so as long as human population continues to grow. Also, the quality of human diet, especially nutritional components, is adversely affected due to limited genetic improvement of most of fruit trees. Thus there is an immediate need to increase productivity of trees. Improvement has been made through conventional breeding methods, however, conventional breeding is very slow due to long life cycle of trees. A basic strategy in tree improvement is to capture genetic gain through clonal propagation. Clonal propagation via organogenesis is being used for the production of selected elite individual trees. However, the methods are labour intensive, costly, and produce low volumes. Genetic gain can now be captured through somatic embryogenesis. Formation of embryos from somatic cells by a process resembling zygotic embryogenesis is one of the most important features of plants. In 1958, Reinert in Germany and Steward in USA independently reported somatic embryogenesis in carrot cultures. Since then, tremendous progress in somatic embryogenesis of woody and non-woody plants has taken place. It offers a potentially large-scale propagation system for superior clones.

This book was released on 2012-12-06 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings is based on a joint meeting of the two IUFRO (International Union of Forestry Research Organizations) Working Parties, Somatic Cell Genetics (S2.04-07) and Molecular Genetics (S2.04-06) held in Gent, Belgium, 26-30 September, 1995. Although a joint meeting of the two Working Parties had been discussed in the past, this was the first such meeting that became a successful reality. In fact this meeting provided an excellent forum for discussions and interactions in forest bioteclUlology that encouraged the participants to vote for a next joint meeting. In the past decade rapid progress has been made in the somatic cell genetics and molecular genetics of forest trees. In order to cover recent developments in the broad area of biotechnology, the scientific program of the meeting was divided into several sessions. These included somatic embryogenesis, regeneration, transformation, gene expression, molecular markers, genome mapping, and biotic and abiotic stresses. The regeneration of plants, produced by organogenesis or somatic embryogenesis, is necessary not only for mass cloning of forest trees, but also for its application in genetic transformation and molecular biology. Although micropropagation has been achieved from juvenile tissues in a number of forest tree species, in vitro regeneration from mature trees remains a challenging problem in most hardwoods and conifers. The mechanisms involved in the transition from juvenile to mature phase in woody plants are poorly understood. This transition can now be investigated at the molecular level.

Available in PDF, EPUB and Kindle. Book excerpt: At present, plants and agricultural sciences are playing a leading role in providing solutions to problems created by an ever growing world population. Through plant biotechnology scientists are seeking ways to improve crop functions that rapidly promote food production. Agricultural science is being used to experiment with producing plants tolerant to environmental stresses such as drought, salinity and coldness.Of the plant species, woody plants are producing the most abundant biomass resources, playing important roles in the suppression of carbon dioxide increase and supplying huge energy and resources to human beings in the biosphere. These Proceedings discuss the recent results of fundamental and applied research for global resource and energy, biomass production and environmental problems from the aspect of woody science. Topics include: - Formation of the vascular bundle - Biosynthesis of cellulose - Lignin biosynthesis and transgenic woody plants - Cell and tissue culture, and transformation in gymnosperms - Micropropagation of woody plants

Available in PDF, EPUB and Kindle. Book excerpt: This Volume contains the papers presented by twenty-eight invited speakers at the symposium entitled, "Genetic Manipulation of Woody Plants," held at Michigan State University, East Lansing, Michigan, from June 21-25, 1987. Also included are abstracts of contributed poster papers presented during the meeting. That the molecular biology of woody plants is a rapidly expanding field is attested to by the large attendance and high level of enthusiasm generated at the conference. Leading scientists from throughout the world discussed challenging problems and presented new insights into the devel opment of in vitro culture systems, techniques for DNA analysis and manipulation, gene vector systems, and experimental systems that will lead to a clearer understanding of gene expression and regulation for woody plant species. The presence at the conference of both invited speakers and other scientists who work with nonwoody plant species also added depth to the discussions and applicability of the information presented at the conference. The editors want to commend the speakers for their well-organized and informative talks, and feel particularly indebted to the late Dr. Alexander Hollaender and others on the planning committee who assist ed in the selection of the invited speakers. The committee consisted of David Burger (University of California, Davis), Don J. Durzan (University of California, Davis) , Bruce Haissig (U. S. Department of Agriculture Forest Service), Stanley Krugman (U. S. Department of Agriculture Forest Service) , Ralph Mott (North Carolina State University), Otto Schwarz (Univer.sity of Tennessee, Knoxville), and Roger Timmis (Weyerhaeuser Company).

Download or read book Plant Aging written by Roberto Rodríguez and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many, the terms aging, maturation and senescence are synonymous and used interchangeably, but they should not be. Whereas senescence represents an endogenously controlled degenerative programme leading to plant or organ death, genetiC aging encompasses a wide array of passive degenerative genetiC processes driven primarily by exogenous factors (Leopold, 1975). Aging is therefore considered a consequence of genetiC lesions that accumulate over time, but by themselves do not necessarily cause death. These lesions are probably made more severe by the increase in size and complexity in trees and their attendant physiology. Thus while the withering of flower petals following pollination can be considered senescence, the loss of viability of stored seeds more clearly represents aging (Norden, 1988). The very recent book "Senescence and Aging in Plants" does not discuss trees, the most dominant group of plants on the earth. Yet both angiospermic and gymnospermic trees also undergo the above phenomena but less is known about them. Do woody plants senesce or do they just age? What is phase change? Is this synonymous with maturation? While it is now becoming recognized that there is no programmed senescence in trees, senescence of their parts, even in gymnosperms (e. g. , needles of temperate conifers las t an average of 3. 5 years), is common; but aging is a readily acknowledged phenomenon. In theory, at least, in the absence of any programmed senescence trees should -live forever, but in practice they do not.

Download or read book Transformation of Plants and Soil Microorganisms written by Kan Wang and published by Cambridge University Press. This book was released on 2004-01-29 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past fifty years plant breeders have achieved impressive improvements in yield, quality and disease resistance. These gains suggest that many more modifications might be introduced if appropriate genes can be identified. Current DNA techniques allow the construction of transgenic plants and this important new book reviews the current state of knowledge. A team of leading researchers provide in-depth reviews at the cutting edge of technology for laboratory techniques for the transformation of important soil microorganisms and recalcitrant plants of economic value. The book is divided into three sections: soil microorganisms; cereal crops; and industrially important plants. The most effective methods used to date are compared, and their merits and limitations discussed. Some chapters emphasise case studies and applications. In cases where obstacles remain to be overcome, an overview of progress to date is given. The book will serve as a general guide and reference tool for those working on transformation in microbiology and plant science.
Download or read book In Vitro Culture of Trees written by J.M. Bonga and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Woody plants provide many challenges to the tissue culturist. Although there are many excellent tissue culture books and manuals available, these are generally strongly biased towards herbacious crops. Consequently, they often do not pay sufficient attention to the problems that specifically apply to in vitro culture of tree species. Culture of the latter often poses problems which are either absent or of lesser significance when culturing herbacious species. When trees in the field are used as explant source, the problems can be especially severe. For example, the physiological condition of the explants is difficult to control because of variation in weather and biotic factors. Furthermore, it is often difficult to obtain explants free of contaminants from field grown trees. Lack of genetic uniformity and maturation are additional problems one often has to deal with when culturing tree cells or tissues. These problems are emphasized in this text. In vitro culture of trees is not viewed in isolation. It is considered in conjunction with breeding, traditional cloning and other common tree improvement techniques. The text discusses theoretical as well as practical aspects of the in vitro culture of trees.
