Elastic proteins occur in a wide range of biological systems where they have evolved to fulfill precise biological roles. The best known include proteins in vertebrate muscles and connective tissues, such as titin, elastin, fibrillin and spider silks. Interest in elastomeric proteins is currently high for several reasons. Firstly, they have biological and medical significance, particularly in human disease. Secondly, the unusual properties of proteins such as spider silks provide opportunities to develop novel materials. Thirdly, the development of scanning probe microscopy makes it possible...

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...
