Figure 4. Distribution of sRNA annotation categories in dormant embryos (white bars) and germinated embryos (black bars).

Sequences that matched to known RNAs accounted for small fractions, 27.40% and 44.05% of the redundant sequences in the dormant and germinated libraries, respectively. Thus, an overrepresented part of the nonredundant sRNAs was composed of unknown sRNAs.
