This book provides a comprehensive overview of cutting-edge biotechnological approaches for enhancing plant secondary metabolites to address abiotic stress, offering valuable insights into the future of utilizing plants for medicinal and industrial purposes. Various books on plant secondary metabolites are available, however, no book has an overview of the recent trends and future prospects of all the methods available to enhance the contents of the plant secondary metabolites. Plant Secondary Metabolites and Abiotic Stress aims to give an overview of all the available strategies to ameliorate abiotic stress in plants by modulating secondary metabolites using biotechnological approaches including plant tissue cultures, synthetic metabolic pathway engineering, targeted gene silencing, and editing using RNAi and CRISPR CAS9 technologies.
