The Role of Biotechnology for Conservation and Biologically Active Substances Production of Rhodiola rosea: Endangered Medicinal Species

open access: yesThe Scientific World Journal, Volume 2012, Issue 1, 2012., 2012
At present, more than 50 000 plant species are used in phytotherapy and medicine. About 2/3 of them are harvested from nature leading to local extinction of many species or degradation of their habitats. Biotechnological methods offer possibilities not only for faster cloning and conservation of the genotype of the plants but for modification of their ...
