FIGURE 4.
Effects of melatonin on the expression of genes involved in K+ transport. Six-day-old bermudagrass plants were transferred to MS or LK medium with or without 50 μm melatonin for 48 h, and then total RNAs isolated from roots and shoots were used for quantitative RT-PCR analysis. Data shown are the mean ± SD (n = 3). Different letters indicate significantly different values (P < 0.05 by Tukey’s test).
