Gene Manipulation in Plant Improvement by J. Perry Gustafson Pdf

The results obtained to date involving the use of in ~ methods to facilitate wide hybridization in plants are voluminous and impressive. The techniques of embryo culture, ovule culture, and in~ pollination and fertilization represent an extension of the normal sexual hybridization process. Successes recorded in obtaining hybrids stem largely from circumventing prezygotic or postzygotic hybridization barriers. Numerous recent successful hybridizations were possible because of the development of improved tissue and cell culture systems for crop plants and attention given to genotypes used in hybridization attempts. Interspecific and intergeneric hybridization utilizing the process of protoplast fusion will bypass the limits set by all sexual me'thods. In addition to combining complete genomes from two different species through protoplast fusion, this system affords unique opportunities for creating novel cytoplasmic combinations, transfer of individual chromosomes, transfer of cytoplasmic organelles, manipulation of male sterility, and for single gene transfer. Some caution must be noted with regard to the extent of hybridization possible between distantly related species. Although practically no limit exists to the physical fusion of protoplasts from widely divergent species, the restrictions imposed by somatic incompatibility have not been adequately addressed. Regeneration of plants from the protoplast or single heterokaryon level is still a major hurdle for many important crop species before somatic cell fusion can be exploited to produce interspecific and intergeneric hybrids. Identification and selection of hybrids is also a limitation to the efficient application of cell fusion methods.

Gene Manipulation in Plant Improvement II by J. Perry Gustafson Pdf

There are clearly many directions in which the further development of the GUS gene fusion system can progress. Some of these have been outlined above, but others can be imagined. There are no reasons to limit our conceptions of the use of GUS gene fusions to analysis and manipulation of single genes. We can envision numerous marked genes - perhaps with several new fusion systems - giving valuable information about gene interaction, or population structure. The study of plan- pathogen and plant symbiont interactions can progress rapidly with simple quantitative markers for genes and individuals. We can imagine ways of using gene fusions to report on crop physiology or other complex phenotypes, thereby enhancing the accuracy and speed of screening. Introduction of the biosynthetic pathway for glucuronide detoxification by expressing genes for the UDP-glucuronyl transferases in plants may result in novel mechanisms for plants to deal with xenobiotics such as insecticides or herbicides. Synthesis of substrates, which until now has been performed chemicall- resulting in expensive compounds - can be done biosynthetically. This should make the system not only the most powerful gene fusion system for agriculture, but also the most accessible.

Applications of Genetic Engineering to Crop Improvement by G.B. Collins,Joseph F. Petolino Pdf

The contributions of plant genetics to the production of higher yielding crops of superior quality are well documented. These successes have been realized through the application of plant breeding techniques to a diverse array of genetically controlled traits. Such highly effective breeding procedures will continue to be the primary method employed for the development of new crop cultivars; however, new techniques in cell and molecular biology will provide additional approaches for genetic modification. There has been considerable speculation recently concerning the potential impact of new techniques in cell and molecular biology on plant improvement. These genetic engineering techniques should offer unique opportunities to alter the genetic makeup of crops if applied to existing breeding procedures. Many questions must be answered in order to identify specific applications of these new technologies. This search for applications will require input from plant scientists working on various aspects of crop improvement. This volume is intended to assess the interrelationships between conventional plant breeding and genetic engineering.

Safety of Genetically Engineered Foods by National Research Council,Institute of Medicine,Board on Agriculture and Natural Resources,Food and Nutrition Board,Board on Life Sciences,Committee on Identifying and Assessing Unintended Effects of Genetically Engineered Foods on Human Health Pdf

Assists policymakers in evaluating the appropriate scientific methods for detecting unintended changes in food and assessing the potential for adverse health effects from genetically modified products. In this book, the committee recommended that greater scrutiny should be given to foods containing new compounds or unusual amounts of naturally occurring substances, regardless of the method used to create them. The book offers a framework to guide federal agencies in selecting the route of safety assessment. It identifies and recommends several pre- and post-market approaches to guide the assessment of unintended compositional changes that could result from genetically modified foods and research avenues to fill the knowledge gaps.

Seeds of Concern by David Ronald Murray Pdf

How are genetically modified plants produced? Which breeding goals are worthwhile, and which are not? Can the escape of transferred genes be controlled? Why have the first transgenic plants been released without full appreciation of the consequences? How dangerous are bacterial proteins produced in plant foods? Is anyone monitoring the unexpected effects of gene transfer? Will genetically modified plants ever be acceptable to organic growers? These are some of the important questions canvassed in this book, written with the insight of an experienced Australian plant scientist and conservationist.

The Methodology of Plant Genetic Manipulation: Criteria for Decision Making by Alan C. Cassells,Peter Jones Pdf

A range of novel techniques is available to the plant breeder today to complement classical breeding methods. The new options are based on the integration of advances in plant cell biology with those in plant molecular biology. Plant cell, tissue and organ cultures provide efficient systems for transformation, for the achievement of wide crosses and for the production of variation through spontaneous and induced mutation, while permitting effective isolation of desired genotypes by in vitro selection. This book presents a critical appraisal of the methodologies of plant genetic manipulation for advanced undergraduates, postgraduates, researchers and plant breeders, and provides guidance on the choice of breeding options. The latter depends on the breeding system of the crop, the breeding objective and the tissue culture systems applicable to the target genotype(s).

Tailoring Genes for Crop Improvement by George Bruening,John Harada,Tsune Kosuge,Alexander Hollaender Pdf

In August. 1982. a conference was held at the University of Califor nia. Davis. to discuss both molecular and traditional approaches to plant genetic analysis and plant breeding. Papers presented at the meeting were published in Genetic Engineering of Plants: An Agricultural Perspective. A second conference. entitled "Tailoring Genes for Crop Improvement." spon sored by the UC-Davis College of Agricultural and Environmental Sciences and the College's Biotechnology Program. was held at Davis in August. 1986. to discuss the notable advances that had been made during the intervening years in the technology for gene modification. transfer. and expression in plants. This volume contains papers that were presented at this meeting and provides readers with examples of how the new experimental strategies are being used to gain a clearer understanding of the biology of the plants we grow for food and fiber; it also discusses how molecular biology approaches are being used to introduce new genes into plants for plant breeding programs. We are grateful to the speakers for their excellent presentations for the conference and extend our sincere thanks to those who contributed manuscripts for this volume.

Genetically Engineered Crops by National Academies of Sciences, Engineering, and Medicine,Division on Earth and Life Studies,Board on Agriculture and Natural Resources,Committee on Genetically Engineered Crops: Past Experience and Future Prospects Pdf

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.
