Additional file 5: Figure S1:
Secondary structures of MIRNA precursor loci and patterns of matching sequencing reads in the Brassica napus A genome (Brassica rapa). For each precursor, small RNA sequencing raw reads (with a minimum number of at least 5 identical reads) from all libraries (10 SOLiD and 17 Illumina, which together total 12 M unique reads) were combined. Annotated miRNA and miRNA* sequences were downloaded from the miRBase database (Release 18). Only reads with perfect matches to the genomic sequence are shown. Green represents the forward (5’ to 3’) reads, red represents reverse reads. The number of reads of each sequence (read count) was integrated into the sequence name as _x [read count for each unique sequence]. The most likely (most abundant) mature miRNA sequence from each MIRNA locus was underlined in red.

Putative novel Brassica napus MIRNAs based on the Brassica A genome (Brassica rapa). The read mapping patterns are displayed and the putative novel miRNA mature sequences underlined in red. Only reads with perfect matches are shown. Green represents the forward reads, red color represents reverse reads. The read count for each specific sequence was integrated into the sequence name as _x [read count of each unique sequence]. The secondary structures of each locus with their folding energy are shown below the genomic sequence.

Additional file 8: Figure S5:
BiNGO graph of enriched GO terms associated with miRNA targets (based on Arabidopsis homologs). The size of node indicates the number of genes in a GO category. The yellow and orange nodes represent terms with significant enrichment, with darker orange representing a higher degree of significance, as shown by the legend. White nodes are terms with no significant enrichment, but are included because they have a significant child term. Branches of GO with no significant terms are not shown.

Additional file 12: Figure S3:
Integration of putative miRNAs identified from Zhao et al.  into mapping results reported in this paper. The mapping patterns of sequence reads to 10 putative miRNA loci are displayed. Three sequences from Zhao et al. were also predicted as novel miRNAs in this study. They are miR2203, miR2204, miR2207, corresponding to our miR5802, miR5806, miR5803. miR2202 is identical to our miR5802*. Because the Zhao et al. designations miR2202-miR2225 were assigned to other species in miRBase (Release 18), we retained our assigned numbers (miR5801-miR5810) for these novel putative miRNAs. Mapping patterns suggest that Zhao et al. miRNAs 2205, 2206 and 2225 are actually siRNAs.
