A single peak at the melting temperature of the PCR-product confirmed primer specificity. Relative gene expression of each gene were analysed using ΔΔCT Method [52]. The data were analysed with Ct values in normal and stress conditions and using the following equation: ΔΔCT = (CT,Target ‒ CT,actin)normal ‒ (CT, Target ‒ CT,Actin)stress. AC220 research buy The fold change in Bxy-ctl-1 and Bxy-ctl-2 was normalized to Bxy-act-1 and relative to the expression at normal conditions, was calculated for each sample using the equation above. Statistical analysis Statistical analysis was performed using SPSS 11.5. Data represent the mean ± standard
error (SE). Statistical significance was inferred by one-way ANOVA and post hoc multi-comparison Duncan test.
