Safety of Genetically Engineered Foods


Book Description

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.




Haploids in Crop Improvement II


Book Description

Doubled haploid technology is an important tool for plant breeding. It allows for significant time reduction in the achievement of homozygous breeding lines of value in crop improvement. This volume provides an excellent overview of haploid induction and the application of doubled haploids. The authors emphasize advances made in the understanding of microspore embryogenesis, but treat also advances in gynogenesis and the manipulation of parthenogenetic haploid development. The text contains a thorough discussion of the application of haploidy to the improvement of a number of species from various families, including Brassicaceae, Poaceae, and Solanaceae. The various methods applicable to these species are described in detail. Each chapter contains critical evaluation of the scientific literature and an extensive list of references. This volume is ideally suited for plant breeders, geneticists, and plant cell biologists.




Brassicas and Legumes From Genome Structure to Breeding

Genome sequence studies have become more and more important for plant breeding. Brassicas and Legumes: From Genome Structure to Breeding comprises 16 chapters and presents both an overview and the latest results of this rapidly expanding field. Topics covered include: genome analysis of a flowering plant, Arabidopsis thaliana; the sequence of the Arabidopsis genome as a tool for comparative structural genomics in Brassicaceae; application of molecular markers in Brassica coenospecies; the molecular genetic basis of flowering time variation in Brassica species; quantitative trait loci for clubroot resistance in Brassica oleracea; structural differences of S locus between Brassica oleracea and Brassica rapa; Brassica and legume chromosomes; sequence analysis of the Lotus japonicus genome; introduction of an early flowering accession ‘Miyakojima’ MG-20 to molecular genetics in Lotus japonicus; genetic linkage map of the model legume Lotus japonicus; construction of a high quality genome library of Lotus japonicus; genome analysis of Mesorhizobium loti: a symbiotic partner to Lotus japonicus; molecular linkage map of the model legume Medicago truncatula; genetic mapping of seed and nodule protein markers in diploid alfalfa (Medicago sativa); mapping the chickpea (Cicer arietinum) genome: localization of fungal resistance genes in interspecific crosses.




Brassica


Book Description

Recent advances in plant cell and molecular biology have opened new avenues for the improvement of crop plants in the genus "Brassica" - oilseeds and vegetables of worldwide economic importance. This volume reviews advances in various areas of "Brassica" biotechnology. It covers the use of rapid-cycle brassicas, tissue culture and gene transfer, molecular genetics, biotic and abiotic stress resistance, and molecular farming. Contributors are world-leading international "Brassica" researchers. The volume is an invaluable reference for plant breeders, researchers and graduate students in the fields of plant biotechnology, agronomy, horticulture, genetics, and cell and molecular biology.




Tobacco BY-2 Cells


Book Description

The first compilation of a wealth of knowledge on tobacco BY-2 cells, often cited as the HeLa cell line of higher plants. Basic issues of cell cycle progression, cytokinesis, cell organization and factors that are involved in these processes are covered in detail. Since the tobacco cell line is used as a tool for research in molecular and cellular biology, several chapters on such studies are also included. Further, changes of primary and secondary metabolites during culture and factors that affect these processes are treated. Last but not least, the so far unpublished historical background of the BY-2 cell line is described. This volume is a must for any scientist working in the field of plant biology.

Somatic Hybridization in Crop Improvement II


Book Description

This richly illustrated volume describes how somatic hybrids can contribute to the improvement of crops. It comprises 24 chapters dealing with interspecific and intergeneric somatic hybridization and cybridization, providing valuable tools for plant breeders.




Cryopreservation of Plant Germplasm I


Book Description

The germ plasm of numerous plant species, especially those of forest trees, some agricultural crops, and medicinal plants, is endangered and threatened with extinction. This depletion of germplasm pools and the shrinkage of naturally occurring genetic resources have caused international concern. Conventionally, the germplasm of plants is conserved through seeds, tubers, roots, corms, rhizomes, bulbs, cuttings, etc. However, the germ plasm of a number of trees and plantation crops (such as coconut, cocao, coffee, oil palm, rubber, mango, horse chestnut, etc. ) cannot be preserved since their seed are short-lived (recalcitrant). Likewise, germplasm of vegetatively propagated crops (such as potato and cassava) cannot be stored on a long term basis and has to be grown and multiplied periodically in nurseries and fields. The plants are thus exposed to unpredictable weather conditions and diseases, with the result that instances are known where entire genetic stocks are lost. Therefore, unconventional methods are being developed for the storage and international exchange of germplasm. For this purpose in vitro cultures have been employed, but they can only enable short-to medium term preservation; moreover, cell cultures upon repeated subculture undergo genetic erosion. In view of the recent developments in the in vitro induction of genetic variability through somaclonal variation, somatic hybridization, recombinant DNA technology, etc. , new methods need to be employed for the storage of desirable cultures. In this regard freeze preservation of cells in liquid nitrogen (-196 0q, like that of semen, enables long-term storage, theoretically, for an indefinite period of time.
