This book is a unique book, providing a rich source of information on seed development. Seed development is a key step of the plant life cycle that determines the nutrient value of seeds. The nutrient value of seeds is mainly due to storage reserve products such as carbohydrates, lipids (triacylglycerols), and proteins. Omics-oriented approaches have unraveled the mystery of seed biology at an unexpected pace - faster than ever imagined. Containing many important features including physiological and morphological variations in seed species, application of high-throughput technologies in generating datasets and their analysis to drive physiology and biology, integration of such technologies with breeding and other classical approaches in improving seed quality and crop yield and food quality and safety assessment, and a huge reference compilation. These features make this book highly valuable for readers including students. Each chapter of this book has been written and edited by highly experienced scientists. This book is also very useful for all aspects of research in plant biology. The scope of this book is wide including its usefulness in the pharmaceutical industry and medical research given the fact that crop plants are the target for producing proteins / drugs in nutrition (vitamin A) and medicine. In conclusion, the book serves as a reference and textbook in the field of plant seed development, and will further fuel the explosion of interest in this young and dynamic biological discipline. The basic and advanced knowledge translated more appropriately in this book will help in developing integrated strategies to eventually improve the nutritional value of plant seed and crop yield, a critical goal in food security issues around the globe.
