Book Synopsis Chromosome Manipulation for Plant Breeding Purposes by : Pilar Prieto
Download or read book Chromosome Manipulation for Plant Breeding Purposes written by Pilar Prieto and published by MDPI. This book was released on 2021-01-29 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to exploit the potential of wild relatives carrying beneficial traits is a major goal in breeding programs. However, it relies on the possibility of the chromosomes from the crop and wild species in interspecific crosses to recognize, associate, and undergo crossover formation during meiosis, the cellular process responsible for producing gametes with half the genetic content of their parent cells. Unfortunately, in most cases, a barrier exists preventing successful hybridization between the wild and crop chromosomes. Understanding the mechanisms controlling chromosome associations during meiosis are of great interest in plant breeding and will allow chromosome manipulation to introduce genetic variability from related species into a crop. In addition to interspecific hybrids, other materials, such as natural and synthetic polyploids and introgression lines derived from allopolyploids, among others, are powerful tools in the framework of plant breeding. For example, an extra pair of alien chromosomes in the full genome complement of a crop species has been frequently used as a first step to access genetic variation from the secondary gene pool in breeding programs. In addition, such introgression lines are also pivotal in the study of interspecific genetic interactions, in the chromosomal location of genetic markers, and in the study of chromosome structure and behavior in somatic and meiotic cells. Contained in this Special Issue are accounts of original research, including new tools to identify chromosome introgressions and the development and characterization of introgression lines and interspecific hybrids carrying desirable agronomic traits for plant breeding purposes. Also included are reviews about the chromosome engineering of tropical cash crops and the effect of chromosome structure on chromosome associations and recombination during meiosis to allow chromosome manipulation in the framework of plant breeding.

Book Synopsis Gene Manipulation in Plant Improvement by : J. Perry Gustafson
Download or read book Gene Manipulation in Plant Improvement written by J. Perry Gustafson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 667 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Safety of Genetically Engineered Foods by : National Research Council
Download or read book Safety of Genetically Engineered Foods written by National Research Council and published by National Academies Press. This book was released on 2004-07-08 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Genetic Manipulations with Plant Material by : Lucien Ledoux
Download or read book Genetic Manipulations with Plant Material written by Lucien Ledoux and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mankind, throughout history, has strived to improve his food sources. By means of slow and empirical selections, it has been possible to greatly increase both quantity and quality of plant crops. This procedure has brought the most useful cereals to a state of refinement that seems to be difficult to further improve by the same methodology. Indeed, natural sexual mechanisms were always used to cross closely related sexually and genetically compatible organisms; the selection procedure consisted of isolating the most promi sing progenies. Obviously, by this way, plants could only share preexisting genetic pools. On the other hand, the last decade has seen drastic modifi cations of the experimental plant sciences, with the appearance of new technological possibilities. Because of this profound reshaping of our experimental ap proaches, other means can now be realistically envisaged in order to achieve similar or even higher goals. It is, for instance, possible to attempt completing sexual crosses (where both male and female gametes bring together the genetic informations necessary for growth and development of the offspring) by parasexual means by which novel genetic informa tions could possibly be added to the heritage •. At the limit, such genetic manipulations could enable man to create plants capable of producing new substances characteris tic of unrelated plants or, more generally, of other living or ganisms. Even if these possibilities might appear quite remote, the interest of Scientists has been awaken and, indeed, several at tempts to such genetic manipulations have already been made.
Book Synopsis Cytogenetics in Plant Breeding by : J. Sybenga
Download or read book Cytogenetics in Plant Breeding written by J. Sybenga and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introductory discussion of basic chromosome structure and function preceeds the main text on the application of cytogenetic approaches to the analysis of the manipulation of both the genetic make-up and the genetic transmission system of plant breeding material. Analysis using light and electron microscopy, segregations and molecular techniques, yields information for assessing the material before and after manipulation. Much attention is given to quantitative methods. Manipulation not only involves the construction of specific genotypes, but also chromosomal transmission systems. Although analysis and manipulation in the somatic cycle are considered, the focus is on the generative cycle, with emphasis on analysis and subsequent segregation of specifically constructed material. The book is intended for plant breeders and other scientists interested in the analysis and manipulation of breeding material at the chromosomal level. Comparisons with molecular and cell biological approaches are made, and the potential of the various methods is evaluated.
Book Synopsis Gene Manipulation in Plant Improvement II by : J. Perry Gustafson
Download or read book Gene Manipulation in Plant Improvement II written by J. Perry Gustafson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
