Systematic model showing (1) epigenetic regulation of MT biosynthesis, (2) transcriptional regulation of MT and SA through heat shock factors (HSFs), and (3) fine-tuning of ASMT2/PR1-related activity. HDA9: HISTONE DEACETYLATION 9; HSP 90: Heat Shock Protein 90; PBS3: AVRPPHB SUSCEPTIBLE3; PP2C1/12: protein phosphatase; MT: melatonin; SRS1: SHI-related sequence; TDC2: tryptophan decarboxylation 2; T5H: tryptamine-5-hydroxylase; ASMT2: N-acetylserotonin O-methylthransferase 2, PR1: pathogenesis-related protein 1.
