RELATIONSHIPS EVALUATION ON SIX HERBAL SPECIES (CURCUMA) BY DNA BARCODING
Abstract
Three chloroplast regions, rbcL, psbA-trnH and petA-psbJ were applied to assess the genetic relationships among six Curcuma medicinal species, which are difficult to distinguish from morphology. The Maximum Parsimony tree was conducted by Kimura 2-parameter model with MEGA 4. The genetic relationships were linked with geographical distributions among these six species; Curcuma sichuanensis is a mutation species of Curcuma longa, Curcuma sichuanensis couldn’t be defined as a single species, and Curcuma chuanhuangjiang is an individual species.
