Fig. 2From: Carotenoid metabolism during bilberry (Vaccinium myrtillus L.) fruit development under different light conditions is regulated by biosynthesis and degradationExpression of carotenoid biosynthetic genes VmPSY (a), VmPDS (b), VmZDS (c), VmCRTISO (d), VmLCYB (e), VmBCH (f), VmLCYE (g) and VmCYP450-BCH (h) during bilberry fruit development. The relative expression of the genes was quantified by qRT-PCR and normalized to VmGAPDH. Values represent means ± SEs of at least three replicates. S1–S5 indicates the fruit developmental stages from flower to fully ripe berryBack to article page
