22-Nucleotide siRNAs Are Differentially Enriched in Long Hairpin dsRNAs Rather Than in LTR-TEs.
(A) to (C) Length distributions of putative siRNAs mapped on long hairpin dsRNAs. (A) Count of unique sequences; (B) and (C) total reads.
(D) An example of a long hairpin dsRNAs generating more 22-nucleotide siRNAs than 24-nucleotide siRNAs. The loop region of ∼500 bp is not shown, and paired regions in stem are 99% in identity. Bubbles indicate unmatched nucleotides.
(E) to (G) Length distributions of putative siRNAs mapped on full-length LTR-retrotransposons. (E) Count of unique sequences; (F) and (G) total reads.
