Book Description
Plant proteases are involved in most aspects of plant physiology and development, playing key roles in the generation of signaling molecules and as regulators of essential cellular processes such as cell division and metabolism. They take part in important pathways like protein turnover by the degradation of misfolded proteins and the ubiquitin-proteasome pathway, and they are responsible for post-translational modifications of proteins by proteolysis at highly specific sites. Proteases are also implicated in a great variety of environmentally controlled processes, including mobilization of storage proteins during seed germination, development of seedlings, senescence, programmed cell death and defense mechanisms against pests and pathogens. However, in spite of their importance, little is known about the functions and mode of actions of specific plant proteases. This Research Topic collects contributions covering diverse aspects of plant proteases research.

Book Description
Toxic Constituents of Plant Foodstuffs focuses on toxic substances in foods of plant origin, including protease inhibitors, hemagglutinins, goitrogens, cyanogens, saponins, gossypol, lathyrogens, and allergens. The book also considers adventitious toxic factors in processed foods and miscellaneous toxic factors such as stimulants and depressants, hypoglycemic agents, toxic amino acids, metal-binding constituents, and hepatotoxins. This volume is organized into 13 chapters and begins with an overview of protease inhibitors, including their distribution in the plant kingdom, physical and chemical properties, and mechanism of interaction with proteases. The next chapters focus on the adventitious introduction of toxic factors into processed plant foods; the inactivation of the trypsin inhibitor and hemagglutinin found in legumes by cooking; and the extraction of a nontoxic, edible starch from cycads. The reader is also introduced to lathyrism, the toxicity of agglutinins, occurrence of goitrogens in thioglucoside-containing plants, and dietary sources of cyanogen. This book will be of interest and value to food scientists who are concerned with the safety of food supply and public health officials tasked with enforcing regulations necessary to ensure the safety of a particular food.

Book Description
As food producers, plants are constantly under attack by insects. Over the course of evolution, plants have not only developed a sophisticated defense apparatus but have also refined biochemical defense mechanisms to protect themselves, thereby maintaining the ecological balance. Plant-pest interactions induce an elaborate array of reactions involving the release of volatile compounds, effector and signaling molecules, trans-membrane proteins, and a variety of enzymes and hormones. This book offers a comprehensive guide to the strategies that plants employ against insects and other pests to ensure their continued survival. Addressing an important gap in the literature, it shares the latest findings in the field of plant–pest interactions for a broad audience. Providing an overview of the current state of knowledge on plant-pest interactions and their role in the genetic improvement of crops, it offers an essential guide for researchers and professionals in the fields of agriculture, plant pathology, entomology, cell biology, molecular biology and genetics.

Book Description
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.

Book Description
Soybean protei ns are wi de 1 y used inhuman foods ina vari ety of forms, including baby formulas, flour, soy protein concentrates, soy protein isolates, soy sauces, textured soy fibers, and tofu. The presence of inhibitors of digestive enzymes in soy proteins impairs nutritional quality and possible safety of this impportant legume. Normal processing conditions based on the use of heat do not completely inactivate these inhibitors, so that residual amounts of plant protease inhibitors are consumed by animals and man. Inhibitors of digestive enzymes are present not only in legumes, such as soybeans, lima beans, and kidney beans, but also in nearly all plant foods, including cereals and potatoes, albeit in much smaller amounts. The antinutritional effects of inhibitors of proteolytic enzymes have been widely studied and can be ameliorated by processing and/or sulfur amino acid fortification. A more urgent concern is reports that rats fed diets containing even low levels of soybean-derived inhibitors, which are found in foods such as soy-based baby formulas, may develop over their lifespan pancreatic lesions leading eventually to neoplasia or tumor formation. On the other hand, recent stUdies suggest that certain enzyme inhibitors from plant foods may prevent cancer formation in other tissues. A key question, therefore, is whether inhibitors from plant foods constitute a human health hazard.

Book Description
"This series of meetings bring together experts working in this field of Science from throughout the world. A major feature of each conference session is an invited review, which outlines the advances that have been made in a particular area since the last meeting. A major factor that was considered at this meeting was the likely impact of plant genetic modification on the nutritional quality of their seeds for human and animal feeding. As an example already a number of legume species and rapeseed have been modified to improve the sulphur amino acid content of their seed and thus their protein quality. Besides the major grain legume species and rapeseed that had been discussed at previous meetings in this series number of crop products, as potential protein sources, for animal feeding, were considered for the first time. These included cottonseed meal, linseed meal, and sunflower seed meal. The potential of some new exotic crops from Mexico was also covered including Mexican species of the genus Lupinus and a Mexican plant from the same family as castor bean, which has a very high oil content but is usually toxic. Work from Cuba compared the nutritional characteristics of soybean with a range of tropical grain legume species, which have received little previous attention. A major change at this meeting was the greater consideration of the effects, both positive, and negative, of the consumption of these seeds for human nutrition. A major review on the development of allergnicity to legume seed in humans is included. There was also consideration of the potential role of antinutritional factors in reducing the growth of various types of tumour cells. The presented papers also suggest that the consumption of legume seed in the diet can potentially reduce serum cholesterol levels. Overall from the 5 conference sessions there are 52 papers. Of these 7 are major invited reviews on the current state of research in this important area for human and animal feeding."
