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

Wei W, Li QT, Chu YN, Reiter RJ, Yu XM, Zhu DH, Zhang WK, Ma B, Lin Q, Zhang JS, Chen SY - J. Exp. Bot. (2014)

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.

Melatonin enhances expressions of photosynthesis-related genes under normal and salt stress conditions. (A) Expression of genes related to photosynthesis. Red colour indicates up-regulation and green colour indicates down-regulation. Quadrangle represents a comparison of melatonin treated versus water control; circle represents a comparison of salt versus water control: triangle represents a comparison of salt plus melatonin versus salt. (B) Relative gene expression level analysed by q-PCR. A GmTubulin fragment was amplified as an internal control. Bars indicate standard deviation (n=3).

Figure 9: Melatonin enhances expressions of photosynthesis-related genes under normal and salt stress conditions. (A) Expression of genes related to photosynthesis. Red colour indicates up-regulation and green colour indicates down-regulation. Quadrangle represents a comparison of melatonin treated versus water control; circle represents a comparison of salt versus water control: triangle represents a comparison of salt plus melatonin versus salt. (B) Relative gene expression level analysed by q-PCR. A GmTubulin fragment was amplified as an internal control. Bars indicate standard deviation (n=3).

Mentions: To confirm the results of transcriptome analysis, we extracted RNA from independently grown and treated plants and performed quantitative RT-PCR. The important genes that enriched in pathway analysis were tested and the real-time PCR results were consistent with transcriptome analysis (Figs 9B, 10B, 11B, and Supplementary Fig. S4B).
