CONTENTS About the Book Biotechnological approaches have the potential to augment the supply of plant-based compounds the demand for which is increasing. The book provides a comprehensive account of such approaches. This book comprises topics such as secondary metabolites production in culture using different approaches such as optimization, selection, biotransformation and possible mechanism of production, genetic transformation using Agrobacteriunm rizogenes, and use of different types of bioreactor systems. Diverse compounds such as alkaloids, steroids, insecticides, antitumour agents and foood additives, metabolites from fungi, lichens and plants are arranged in different chapters. Chapters on techniques used for the study of cells and production of secondary metabolites are also included. The book will serve as a source material for students, teachers and researchers working in the fields of agriculture, botany, biotechnology, pharmacy and environmental sciences.
