title: [Sequence analysis of 25S rDNA from Chinese medicinal plant duzhong Eucommia ulmoides Oliv].
abstract: OBJECTIVE
  To provide new molecular data for the identification of the Chinese medicinal plant Duzhong (Eucommia ulmoides).
  
  
  METHODS
  Sequencing and analyzing the 25S rDNA gene(rDNA) 5' terminal region.
  
  
  RESULTS
  More than 300 nucleotides of 25S rDNA 5' terminal region were determined, and the specific nucleotides can be used for the identification of this medicinal plant.
  
  
  CONCLUSIONS
  This sequence analysis may serve as a basis for preparing the specific rDNA probe.
