This book addresses the literature gap by providing both theoretical foundations and practical insights into in vitro plant secondary metabolite production. It emphasizes the urgency to address the strategies and scientific methods for producing the secondary metabolites in the laboratory conditions. This book includes chapters on various in vitro strategies and laboratory methods, which are crucial for understanding and implementing techniques in this applied field. It equips the readers with the knowledge essential for contributions to pharmaceuticals, agriculture and various industries, thus filling a critical void currently present in the literature and practical applications in this field. This book is structured to cater to a diverse audience, including graduate students and researchers. It is specifically tailored to address the key aspects of plant cell, tissue and organ culture, and aligns seamlessly with the curriculum requirements for the courses offered in plant biotechnology. The modules on cell cultures, secondary metabolite production, and metabolic engineering are also integral components for these courses.
