Defense-related Proteins in Plants presents detailed information on these important mechanisms in plants, including their identification, characterization, mechanism of action, and application in crop improvement programs in a single, cohesive, and comprehensive volume. The foundational information included enables understanding of these proteins and their application in crop improvement programs. The book is a complete guide about defense-related proteins in plants for various categories of readers that will inspire future research into the unexplored areas of molecular aspects of these proteins to understand their role and action mechanism in plants and living organisms as a whole. Defense-related proteins have drawn the attention of various plant and agricultural scientists and industries because they provide generalized direct stress tolerance in crop plants. These proteins including lectins, chitinases, thaumatin, and osmotin, among others, have been used for the development of transgenic plants to provide protection against various abiotic and biotic stresses. While there is a breadth of research and application information available, it has not, until now, been compiled into a single volume for ease of comparison and translational work.
