In this book, various plant molecular farming strategies to produce commercially viable molecules for industrial and pharmaceutical use are discussed. The book reviews some affordable technologies and strategies being established to increase the production and quality of plant-derived medicines, which are used in the pharmaceutical industry. It also mentions biosafety and regulatory factors, which are essential to eliminate possible health and environmental hazards (when strictly followed), and these are consequently essential to win public recognition, thus guarantee the industry's success. The book focuses on two main issues: the opportunities and challenges presented by contemporary plant molecular farming methods. It presents plant molecular farming as the future of pharmaceuticals industry.
