Melatonin enhances plant growth and abiotic stress tolerance in soybean plants.

Bottom Line: In the present study, we tested the effect of melatonin (N-acetyl-5-methoxytryptamine) on soybean growth and development.Transcriptome analysis revealed that salt stress inhibited expressions of genes related to binding, oxidoreductase activity/process, and secondary metabolic processes.Melatonin up-regulated expressions of the genes inhibited by salt stress, and hence alleviated the inhibitory effects of salt stress on gene expressions.

Mentions: Gene ontology analysis also was performed (http://www.geneontology.org/). Melatonin exhibited similar regulatory roles in both “Mt:H2O” and “NaCl+Mt:NaCl” comparisons, whereas salt stress inhibited related gene expressions. Regulated gene numbers were higher in the “Mt:H2O” comparison. Melatonin apparently increased genes related to hydrolase, oxidoreductase, primary metabolism, oxidation-reduction processes, and lipid metabolic processes, whereas salt stress had an inhibitory effect on these processes (Fig. 7).
