Enhanced tolerance to drought stress resulting from Caragana korshinskii CkWRKY33 in transgenic Arabidopsis thaliana

It is well known that WRKY transcription factors play important roles in plant growth and development, defense regulation and stress responses. This suggested that the overexpression of CkWRKY33 led to an enhanced drought-stress tolerance in transgenic A. thaliana. Thus, CkWRKY33 may act as a positive regulator involved in the droughtstress responses in Caragana korshinskii.
