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 effects on soybeans grown under field conditions. (A) Comparison of three-week-old plants grown in the field. (B) Phenotypes of six-week-old plants. (C) Comparison of pod numbers from 30 plants. (D) Seed numbers from 30 plants. (E) Seed weight from 30 plants. For C, D, and E, * and ** indicate significant difference (P<0.05 and P<0.01 respectively) compared with mock coating (0 µM). Bars indicate standard deviation (n=4).

Figure 3: Melatonin effects on soybeans grown under field conditions. (A) Comparison of three-week-old plants grown in the field. (B) Phenotypes of six-week-old plants. (C) Comparison of pod numbers from 30 plants. (D) Seed numbers from 30 plants. (E) Seed weight from 30 plants. For C, D, and E, * and ** indicate significant difference (P<0.05 and P<0.01 respectively) compared with mock coating (0 µM). Bars indicate standard deviation (n=4).

Mentions: Soybean seeds coated with 0, 50, or 100 µM melatonin were sowed in four different regions of the same field in the experimental station. Melatonin-treated and untreated plants were grown in rows, one close to each other, and each row had roughly 70 holes. Melatonin-treated plants grew bigger than control seedlings (Fig. 3A, B). After harvest, yield-related traits were measured. Melatonin-treated plants produced more pods, more seeds and more yield than control plants (Fig. 3C–E). The results suggest that melatonin improves plant growth and soybean production under field conditions. An independent field test was also performed in Zhejiang Province and consistent enhancement in soybean yield was observed (data not shown).
