Figure 3: Secondary structure and features of sequences classified by NOVOMIR as pre-miRNAs. Positions in the A. thaliana chromosomes is given above the structures. The predicted miRNA/miRNA* complexes are shown in larger italic characters. The table contains features of the sequences and their structures; the filter values are fraction of base pairs in five windows (with default threshold 𝑡 W D = 0 . 6 5 ), stem-loop length ( 𝑡 H P = 3 0 ), maximal helix length ( 𝑡 B P = 8 ), ratio of sequence and stem length ( 𝑡 R = 6 ). For expression pattern of small RNAs at the genomic location of these sequences, see supplemental Figures S8–S11.
