Relative expression profiling of biosynthetic genes for main pathway flavonoid and anthocyanin synthesis in skin and flesh of ‘Stark Red Gold’ nectarines. The developmental stages are indicated as follows: S1, 50 DAFB; S2, 66 DAFB; S2-3, 74 DAFB; S3, 90 DAFB; S4, 135 DAFB. PpActin used as reference gene. Error bars are standard error of the mean for three replicate reactions.
