Expression patterns of flavonoid pathway genes during fruit development. Total RNA was extracted from RF7-4 (black box) and YW5AF7 (white box) at the green (G), turning (T) and ripe (Rp) stages. RT-qPCR was performed to investigate transcription levels of flavonoid pathway genes. Relative gene expression levels (highest value = 100%) are shown after normalization with FvGAPDH1 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 results are based on at least three repeats in three independent experiments.
