This book aims to present the latest advances in the application of plant biotechnology and molecular biology in disease management. Among these, molecular techniques can be used to accelerate the detection and identification of pests and pathogens in plants. Also, the identification of resistance genes, characterization of desired resistance genes, and transfer of resistance gene(s) into plants have been performed by applying molecular techniques. The book will collect chapters exploring emerging areas of plant biotechnology including RNAi technology, genetic engineering, GWAS, CRISPR, and nanobiotechnology, and their applications in plant disease management and provides the latest concepts and advances in the field of plant pathology, including detection, identification, characterization, classification and diagnosis, host resistance, disease forecasting, management of plant pests and pathogens, and plant biotechnological approaches. This book offers a valuable reference for educators, students, and researchers in all disciplines of the agricultural sciences, life sciences, and biotechnology at universities, research institutions, and biotechnology companies.
