Expression profile of cystatins family genes in soybean nodules at five important nodule development time points. Three biological replica samples and three replicate reactions per sample were used to calculate the expression level of each cystatin during the nodule development. Relative expression levels of each cystatin gene were obtained by qPCR and normalized to the average expression level of soybean reference gene QACT, and calculated using the expression level in 12 dN as a starting point control. Data represent the mean ± SE of nine independent replicate experiments. “★”and “★★” indicate statistical difference between different nodule development time points (t-test, p < 0.05 or p < 0.01, respectively). “★”and “★★” without wire frame marker in (G), indicate statistical difference compared to the 12 dN (starting point control).
