Partial electropherogram of the MSAP analysis on the DNA methylation in Moso bamboo at different chronological ages. E3HM6 and E4HM6 represent the primers used for amplifications. Numbers 2 to 60 represent the nine age samples, 2-, 6-, 7-, 13-, 18-, 32-, 34-, 44-, and >60-year-old. Numbers 1 to 5 represent the five repetitions. Each sample has two lanes labeled by H and M, respectively. H represents amplification products of EcoR I/Hpa II enzyme digestion, and M represents amplification products of EcoR I/Msp I enzyme digestion.
