    Identification of Valeriana fauriei and other Eurasian medicinal valerian by DNA polymorphisms in psbA–trnH intergenic spacer sequences in chloroplast DNA

    In order to differentiate among Valeriana fauriei Briq. and other Eurasian medicinal valerian (V. dioica L., V. hardwickii Wall., V. jatamansi Jones, and V. officinalis L.), we attempted to establish DNA markers....
