title: Discrimination of Korean ginseng (Panax ginsengMeyer) cultivar Chunpoong and American ginseng (Panax quinquefolius) using theauxin repressed proteingene.
abstract: BACKGROUND
  Korean ginseng (Panax ginseng) is one of the most important medicinal plants in the Orient. Among nine cultivars ofP. ginseng, Chunpoong commands a much greater market value and has been planted widely in Korea. Chunpoong has superior quality "Chunsam" (1stgrade ginseng) when made into red ginseng.
  
  
  METHODS
  A rapid and reliable method for discriminating the Chunpoong cultivar was developed by exploiting a single nucleotide polymorphism (SNP) in theauxin repressed proteingene of nine Korean ginseng cultivars using specific primers.
  
  
  RESULTS
  An SNP was detected between Chunpoong and other cultivars, and modified allele-specific primers were designed from this SNP site to specifically identify the Chunpoong cultivar andP. quinquefoliusvia multiplex polymerase chain reaction (PCR).
  
  
  CONCLUSIONS
  These results suggest that great impact to prevent authentication of precise Chunpoong and other cultivars using theauxin repressed proteingene. We therefore present an effective method for the authentication of the Chunpoong cultivar ofP. ginsengandP. quinquefolius.
