a Red light can significantly induce melatonin synthesis in tomato fruit. Determination of melatonin content and quantification of biosynthetic genes in tomato fruit at 10 different development stages under control light (CL) and red light supplement (RLS). Data are represented as mean ± SD (n = 3). In which 10–12 individual fruits were pooled as one biological replicate. b Content of N-acetylserotonin (5) and 5-methoxytryptamine (4) in wild-type tomato fruit after red light treatment. Data are represented as Mean ± SD (n = 3). In which 10–12 individual fruit were pooled as one biological replicate. * indicates a significant difference from control light (CL) analyzed by two-sided Student’s t test. (**P = 0.0054), ns (P = 0.8949), ns indicates not significant (P > 0.05). Source data are provided as a Source Data file. c Melatonin content in fruit of transgenic tomato lines after red light treatment. Data are represented as Mean ± SEM (n = 3). In which 10–12 individual fruits were pooled as one biological replicate. The P values indicate the results from pairwise comparisons of one-way ANOVA tests. Different letters represent a significant difference at P < 0.05. Source data are provided as a Source Data file.
