Performance of CkWRKY33 transgenic Arabidopsis and wild-type (WT) plants under normal growth and drought-stress conditions. Three lines were randomly selected for the phenotypic screening. a Phenotypes of potted WT and transgenic plants after 21 d under normal growth, drought stress conditions and after rewatering; b Survival rates of WT and transgenic lines 2 d after re-watering. Each data point is the mean of three replicates of 20 plants. The error bars indicate the SD, Asterisks indicate statistical significance (*: P < 0.05; **: P < 0.01; Student’s t-test) of differences between transgenic lines and WT; c Expression levels of CkWRKY33 in WT and CkWRKY33-transgenic Arabidopsis plants
