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.

Fatty acid analysis in melatonin-treated plants. Seeds from field-grown plants were analysed for their FA content (% w/w). Bars indicate standard deviation (n=3). * indicates significant difference (P<0.05) compared with mock coating (0 µM).

Figure 12: Fatty acid analysis in melatonin-treated plants. Seeds from field-grown plants were analysed for their FA content (% w/w). Bars indicate standard deviation (n=3). * indicates significant difference (P<0.05) compared with mock coating (0 µM).

Mentions: As acetyl-CoA is the substrate of de novo fatty acid biosynthesis, we further measured fatty acid content in soybean seeds from field-grown plants using gas chromatography. Total FA contents were increased by 1.58% and 2.37% with 50 and 100 µM melatonin treatment, respectively (Fig. 12). These increases were probably due to the major rises of C18:2 composition (Fig. 12).
