  1. The selection was based on several characteristics of the miRNA secondary structure in the duplex including, the number of bulges in the duplex (A), number of the successive unpaired bases in each bulge in the duplex (B), total number of the unpaired bases within the duplex (C), nucleotide number in the loop (D). Training datasets (B: all miRBase species; P: all plants; M: monocot only). The reverse complement sequences of miRNAs used as probes for northern blot validation are presented in Additional file 2: Table S11.
