This book focuses on recent advances in Molecular Tools, Nanotechnology and Artificial Intelligence to monitor, manage and improve horticultural crops in terms of plant growth, nutrient de?ciency, toxicity, diseases, abiotic stress, soil amendments and agrochemicals entering the surrounding environment. The book consists of 11 chapters grouped in 3 parts. Part I Nanotechnology and Artificial Intelligence, Part II Monitoring Abiotic and Biotic Stress, Part III Genetic Engineering and Genomics. This book provides an overview of nanotechnology and omics used to improve the productivity of crops and sustainability in the future. It also describes the basic structures of six popular artificial intelligence techniques and their applications in horticultural crop improvement. The book presents molecular techniques such as molecular markers, genome sequencing, genome editing and genetic modification that are considered ef?cient tools to achieve the goals of plant breeders in horticultural crop improvement programs. Chapters are written by globally recognized scientists and subjected to a rigorous review process to ensure quality presentation and scientific precision. Each chapter begins with an introduction that covers similar contexts and includes a detailed discussion of the topic accompanied by high-quality color images, diagrams and relevant details and concludes with recommendations for future study directions in addition to a comprehensive bibliography.
