There has been a surge in critical situations such as malnutrition, agricultural productivity, viral diseases, noncommunicable diseases, antibiotic resistance, and depletion of natural resourcest hreatening human welfare during the last decade. Fortunately, a parallel unprecedented growth and development have also taken place in various biotechnological sectors, giving hope and direction to meet these challenges.This book has been written with a very clear purpose of highlighting the contributions of modern biotechnology in solving emerging problems in various sectors. It has been divided into four major sections: Agricultural Biotechnology, Healthcare Biotechnology, Environmental Biotechnology, and Industrial Biotechnology. The chapters under each section are dedicated to the latest developments with comprehensive information about background, prospects, and applications. We have tried to incorporate the latest innovative biotechnological solutions such as biofortification, exome sequencing, genome sequencing, RNAi, drug discovery, nutrigenomics, bioremediation, nanobiotechnology and many more which have contributed remarkably in recent years to address the modern challenges in various sectors.The key highlights of this book are as follows:* Multidisciplinary perspective of biotechnological approaches.* Extensive investigation of hot topics. * Updated information with relevant data and statistics. * Application-based study of biotechnology.* Profusely illustrated and labeled diagrams to supplement the descriptions.This fully updated book will serve as a high-value resource book for students, teachers, researchers, and industry personnel in various disciplines of life sciences, agricultural sciences, medicine, environment, and industrial biotechnology. It will serve as a comprehensive resource book to develop an in-depth understanding of the emerging challenges in the areas of human welfare and analyze the latest biotechnological advancements in the direction of solving these concerns.
