Relative expression of 4 mitochondrial genes according to the selected RGs (RPS13 + γ-TUB). (A) nad3, (B) atp6, (C) cob and (D) cox1 in sample sets across the phosphine-susceptible strain (SS) and phosphine-resistant strain (RS) under exposure to phosphine for 0.5 h, 1 h, 2 h, 4 h, 8 h, 12 h and 48 h, respectively. Bars indicate the standard deviation (±SD) evaluated from three biological replicates. The asterisks indicate a statistically significant difference compared with the control, by the Student’s t-test (SS0 and RS0 were the controls, respectively; *P < 0.05, **P < 0.01).
