Expression patterns of SlSR s in rin fruit during development. Total RNA from the rin and wildtype fruit at 10, 20, 30, 45 and 50 DPA was subjected to RT-qPCR analysis. Relative gene expression levels (highest value = 100%) are shown following normalization with actin transcript values. Error bars represent standard error of the mean. For each gene, different letters indicate significant differences among mean values (P < 0.05; t-test). The analyses were repeated at least three times in three independent experiments.
