Fig. 4From: Comparative physiological responses and transcriptome analysis reveal the roles of melatonin and serotonin in regulating growth and metabolism in ArabidopsisMelatonin- and serotonin-induced changes in the expression profiles of key photosynthetic genes. Gradient colors indicate the log2 fold-change in gene expression under different treatments compared to the untreated control. Heat maps of genes in photosystem I and photosystem II.
