Figure 3. The 3′ RACE and 5′ RACE products of ptr-miRNAs amplified by PCR are shown in an ethidium bromide-stained agarose gel.

The sizes of the molecular weight markers of the bottom and the second from bottom bands are 50 bp and 100bp, respectively. Lanes 1–9 are 3′RACE products of ptr-miR156, ptr-miR164, ptr-miR167, ptr-miR171, ptr-miR319, ptr-miR482a, ptr-miR482b, ptr-miR435, and ptr-miR1446, respectively, and lanes 10–18 are the 5′RACE products of them.
