Figure 3From: Developmental and light-entrained expression of melatonin and its relationship to the circadian clock in the sea anemone Nematostella vectensisRelative mRNA expression of melatonin pathway production in Nematostella vectensis. Results of a) tryptophan hydroxylase (TPH)/phenylalanine hydroxylases (PaH) and b) hydroxyindol-O-methyltransferase (HIOMT) in adult individuals of Nematostella vectensis kept in a light–dark (12:12 h) or constant darkness cycle; and c) TPH/PaH and d) HIOMT expression in 2-week-old embryos. Data were normalized by the gene to the ribosomal protein P0. Each point represents five individuals/samples. *Statistically different from light–dark with P <0.05.Back to article page
