title: [Establish efficiently transformation system of the Isatis indigotica].
abstract: OBJECTIVE
  To build up a method of efficiently transforming Isatis indigotica with the Agrobacterium.
  
  
  METHODS
  Two kinds of Agrobocterium: ATCC 15834 and RI1601 were used to treat different fraction of Isatis indigotica. Explored the effect of cocultured, different antibiotic concentration and the media on multiply the hairy roots.
  
  
  RESULTS
  The explants with out coculture had had higher survival rate rooting rate and earlier sprout time. After ultrasonic treatment of plant, the indacement rate was two times than that of untreated one; The best antibiotic concentration was 400 mg/L; The proportion of the grow speed of the hairy root in the liquid culture media was 2 - 3 times than that of solid culture media, and 37 times of common roots.
  
  
  CONCLUSIONS
  The method is useful for establishing an efficiently transformatiem system of Isatis indigotica by Agrobacterium.
