Hairy Root Cultures: A Suitable Biological System

Considering the global approach to the various applications of medicinal plants in the field of therapy and food industry, the production and processing of these plants have become a profitable and important industry around the world. This industry includes the selection and domestication of medicinal plants as well as, their cultivation and processing, and includes various scientific fields. Medicinal products will receive real value when can produce their secondary metabolites in high levels and to be used for treat certain diseases. Recently, the aim of industry is develop in vitro culture techniques of plants such a way that the production of secondary metabolites increased compared to the plant under natural conditions. This book is the review of scientific resources of the world in field of plant tissue culture and genetic engineering particularly hairy root culture system in medicinal plants that focused on providing professional debates about hairy root culture system and ways to increase secondary metabolites.
