Fig. 4From: Expression and functional analysis of citrus carotene hydroxylases: unravelling the xanthophyll biosynthesis in citrus fruitsChanges in the expression of carotene hydroxylase genes in the flavedo (a) and juice sacs (b) during the ripening process. The results shown are the mean ± SE for triplicate samples. The mRNA levels were analyzed by TaqMan real-time quantitative RT-PCR. Real-time RT-PCR amplification of 18S rRNA was used to normalize the expression of the genes under identical conditions.
