Relative expression levels of drought resistance genes in transgenic and EV-transformed Arabidopsis after drought stress. a AtCOR15a, b AtERD15, c AtP5CS1, d AtRD29A. Data are the mean ± SD (standard deviation). The asterisk, (*) and (**), indicates that overexpressed (OEs) and EV-transformed groups of plants were significantly different at P < 0.05 and P < 0.01 (Student’s t-test)
