This book reviews all important aspects of plant genome editing to shed new light on these genome editing technologies together in crop improvement and sustainable agriculture. The book is divided into three areas: the first of which reinterprets plant genome studies from an overview perspective, examining the safety and risk assessment of plants as well as breeding-related outcomes. The second area discusses recent advances in the understanding of crop improvement. A wide range of plant stress tolerance in relation to plant genome editing is then addressed, before turning attention to specific species approaches including rice, maize, wheat, and soybean. The entire book is devoted to an updated knowledge of plant genome editing technologies from all aspects of plant biology and agronomy as we move toward advancements in sustainable life research. The book will be highly recommended for agriculture biologists, agronomists, plant pathologists, and all related research areas.
