Available in PDF, EPUB and Kindle. Book excerpt: Investigations on seed proteins have been intensively carried out during the past two decades. This is valid with regard to both their chemical composition as well as their nutritive value. The development of new biochemical and physical methods has resulted in obtaining deep insights into the structures of seed proteins and their mutual interactions. Intensive exchange of information between the scientists participating in national and international research programmes has given strong impulses for intensifying the research in this field. For the quantitative and quali tative investigations of seed proteins, not only some model plants were used; on the contrary, they were carried out on a large number of different crops important for different regions of the earth. In this way, a level of knowledge has been reached which could not be expected in this diversity within such a short period. This holds not only true for biochemical but also for physiological characters of the species of the limiting amino acids studied. With regard to nutritional aspects, the problem was of special interest, but also seed proteins acting as antinutritional factors were analysed in detail. Based on the knowledge of seed protein structures, it was possible to perform investigations on the genetic basis of their synthesis. This was done under two different aspects: The basic knowledge on the genes involved should be widened; moreover, it should be tried to improve the seed proteins quantitatively and qualitatively under the influence of mutant genes.

Download or read book Nutritional Improvement of Food and Feed Proteins written by Mendel Friedman and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 879 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nutritional quality of a protein depends on the proportion of its amino acids-especially the essential amino acids-their physio logical availability, and the specific requirements of the consumer. Availability varies and depends on protein source, interaction with other dietary components, and the consumer's age and physiological state. In many foods, especially those from plants, low levels of various essential amino acids limits their nutritive value. This is particularly important for cereals (which may be inadequate in the essential amino acids isoleucine, lysine, threonine, and tryto phan) and legumes (which are often poor sources of methionine). Moreover, these commodities are principle sources of protein for much of the earth's rapidly growing population. At the current annual growth rate of about 2 percent, the world population of about 4 billion will increase to 6.5 billion by the year 2000 and to 17 billion by the year 2050. Five hundred milliQn people are presently estimated to suffer protein malnutrition, with about fifteen thousand daily deaths. The ratio of malnourished to adequately nourished will almost surely increase. For these reasons, and especially in view of the limited availability of high quality (largely animal) protein to feed present and future populations, improvement of food and feed quality is especially important.
Download or read book Induced Mutations in Plant Breeding written by W. Gottschalk and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mutation breeding has been introduced into modern plant breeding in the early 1940's. In spite of pessimistic predictions, the application of experimental mutagenesis has led to encouraging results demonstrating that mutation breeding is a well-functioning method in many crops. So far, more than 500 varieties, developed by means of induced mutations, have been officially released; others have been approved for registration. Many mutants with characters of agronomic interest cannot be utilized directly because of their unsatisfying yielding capacities, or of other negative traits which are partly due to the pleiotropic action of the mutant genes. Sometimes their negative selection value can be overcome by transferring them into the genomes of other varieties. According to experience available, the efficiency of mutant genes can conSiderably vary depending on the genotypic background in which they become effective. The interactions between mutant genes and genotypic back ground cannot be predicted. Therefore, mutants with valuable traits should be crossed with many varieties and strains in order to discern positive and negative interactions. In this way, genotypes can be selected in which the mutant gene is able to express its action without showing negative by-effects. This procedure has been used for about 10 years by combining the methods of mutation and crossbreeding. Mutation breeding is predominantly used in annual diploid and allo polyploid self-fertilizing crops, while it causes much more difficulties in cross-pollinating species.
Download or read book Crop Breeding A Contemporary Basis written by P. B. Vose and published by Elsevier. This book was released on 2012-12-02 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to gather together, in an integrated manner, information on the physiology and technology of contemporary plant breeding. The approach is multidisciplinary, with special emphasis being placed on the application of theoretical knowledge to the solution of practical problems concerned with the improvement of crop yield through the breeding of plants better suited to their environment. The role of modern techniques, such as tissue culture and induced mutation are discussed in detail

Available in PDF, EPUB and Kindle. Book excerpt: Plant Breeding Reviews is an ongoing series presenting state-of-the art review articles on research in plant genetics, especially the breeding of commercially important crops. Articles perform the valuable function of collecting, comparing, and contrasting the primary journal literature in order to form an overview of the topic. This detailed analysis bridges the gap between the specialized researcher and the broader community of plant scientists.

Available in PDF, EPUB and Kindle. Book excerpt: First published in 1975, this book looks at the different ways in which food protein can be produced. Special attention is given to sources from which food protein could be made by simple techniques in regions where protein deficiency is acute. Also covered are quality control and the acceptability of novel foods.
Download or read book Plant Proteins written by G. Norton and published by Butterworth-Heinemann. This book was released on 2013-10-22 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Proteins is a compendium of papers discussing, in general, plant proteins as materials for human foods, and in particular, the properties, biosynthesis, deposition of reserves in seeds, undesirable factors, production, and nutritional aspects of plant proteins in the food industry. Some papers review the properties and biosynthesis of plant proteins, the synthesis of chloroplast proteins, and legume seed proteins. Other papers discuss the development of protein reserves in seeds, as well as the toxicity and antagonistic actions in relation to amino acid and protein synthesis. One paper examines the world supply and demand for sources of protein from three plant sources, namely cereals, oilseeds, and legumes. Another paper discusses the capabilities of certain species of micro-organisms to synthesize from a few simple raw materials all the main components needed in the diet of a human or a farm animal. One paper notes that the acceptance of plant protein foods in society depends on their presentation, flavor, texture, appearance, identity, and product name. This compendium will benefit agronomists, agriculturists, biochemists, microbiologists, nutritionists, botanists, chemists, economists, food scientists, physicists and plant breeders.
