Drought-inducible genes in CaAIMK1-OX plants. Quantitative reverse transcription-polymerase chain reaction analysis of CaAIMK1-OX plants exposed to drought stress at 3 h after leaf detachment. The relative expression levels (ΔΔCT) of each gene were normalized to the those of Actin8 as an internal control gene. Data represent the mean ± standard error of three biological replicates. Asterisks indicate significant differences between wild-type (WT) and transgenic lines (Student’s t-test; * P < 0.05).
