title: [Changes of total RNA and mRNA differential expressions in leaves of Pinellia ternata under high temperature stress].
abstract: OBJECTIVE
  To study the total RNA and mRNA differential expression in leaves of Pinellia ternata under high temperature, provide more information of the molecular mechanism of the sprout tumble.
  
  
  METHODS
  The total RNA and mRNA differential expression in leaves of P. ternata at different stress time was analyzed.
  
  
  RESULTS
  The results showed that the trend of total RNA content was divided into three descending stages and two ascending stages, the total RNA content was the highest at 0, 6 h, but it was the lowest at and 42 h, as well as when the sprout tumbled. The differential display showed that the polymorphism and type of bands of the sample at 6 h were similar to those at 0 h. But the bands numbers at other time were far less than those at 0, 6 h. And there were some different mRNA differential expression bands between the different samples.
  
  
  CONCLUSIONS
  In the process of the sprout tumble caused by high temperature stress, the RNA and mRNA differential expression in leaves of P. ternata changed.
