Seed Proteins

Seeds provide more than half of the world's intake of dietary protein and energy and thus are of immense economic, cultural and nutritional importance. Proteins can account for up to 40% of the dry weight of various types of seeds, thereby making a large contribution to the nutritional quality and processing properties of seeds. It is, therefore, not surprising that seed proteins were among the first plant components to be systematically studied, some 250 years ago, and have been a major focus of research over the past 100 years. The properties and behaviour of seed proteins pervade modem life in numerous ways. For example, legume and cereal proteins are used'in the production of a wide range of meat-free foods; the process of bread-making is dep~ndent on the physical chemical properties of wheat seed proteins; and in developed, as well as developing, countries, nutritional deficiencies among vegetarian diets are avoided through balancing legume and cereal seeds as sources of dietary proteins. Understanding seed proteins, in order to improve their composition and properties and to increase their concentrations, will thus continue to be an important research objective for the future. The present volume represents the culmination of a long-discussed plan of the editors, to bring together the best international authorities in order to compile a definitive monograph on biological, biochemical, molecular and genetic aspects of seed proteins.

Klappentext

This volume is the most comprehensive and detailed account of seed proteins so far published and the first dedicated volume for a number of years. It covers the major storage protein groups (prolamins, 2S albumins, 7Sglobulins, and 11S globulins), focusing on those present in crops. It also covers other widely distributed groups of proteins including lectins, inhibitors, antifungal proteins, thionins and oil body protein (oleosins).The breadth of coverage of the proteins is wide, including their structures and properties, evolutionary relationships, classical and molecular genetics and mechanisms of synthesis, trafficking and deposition within thecells. br/ It should therefore become a standard source book for active research scientists as well as for higher level teaching.
