Fig. 6From: Chlortetracycline inhibits seed germination and seedling growth in Brassica campestris by disrupting H2O2 signalingExpression analysis of SOD genes of CTC treated seedlings upon H2O2 treatment. Gene expression was normalized relative to Actin7. Asterisks indicate statistically significant differences relative to the control (Student’s t-test; *p < 0.05, **p < 0.01, ***p < 0.001). Experiments were performed in three independent biological replicates with similar results. The qRT-PCR experiments were replicated three times with similar results (mean ± SD; n = 9)Back to article page
