Supplemental Data

Files in this Data Supplement:

• Supplemental Figure 1 - Supplemental Figure 1A-C. Stem-loop structures of ptr-MIR156e. Ptr-miR156e presents in either 5' arm (A) or 3' arm (B and C) and two stem-loop structures (one is shorter (B) and the other is longer (C)) were found when the miRNA was present in the 3' arm. The ptr-miR156e sequence is underlined.
• Supplemental Table 1 - Supplemental Table 1. Endogenous putative siRNAs from Populus.
• Supplemental Table 2 - Supplemental Table 2. MiRNA location and Gene sequences in Populus, Arabidopsis and rice genomes.
• Supplemental Table 3 - Supplemantal Table 3. Identification of precursor sequences for cloned miRNAs in Populus ESTs.
• Supplemental Table 4 - Supplemental Table 4. Primers for modified 5' RLM-RACE mapping of miRNA cleavage sites.
