Melatonin reduces endogenous BR levels. Seedlings 12 DAG from 1/2MS amended with melatonin, BRZ, or DMSO (control) were collected for the determination of BR levels by ELISA method. (A) Phenotype of seedlings from melatonin, BRZ, or DMSO treatments. (B) Hypocotyl length of the corresponding seedlings. *p < 0.05, **p < 0.01 (Student’s t test). Error bars indicate the SEM (n ≥ 40). (C) Endogenous bioactive BR content. Data are represented as means ± SD (n = 3), *p < 0.05 (Student’s t test). BR, brassinosteroid; BRZ, brassinazole; DAG, days after germination; DMSO, dimethyl sulfoxide; ELISA, enzyme-linked immunosorbent assay; MS, Murashige and Skoog; SEM, standard error of the mean.
