GFP-derived piRNAs are amplified through the ping-pong cycle. (A) Density plot of pPIGA3-derived piRNAs. (B) Strand bias of GFP-derived piRNAs. (C) 1U and 10th A bias of GFP-derived piRNAs. (D) Density plot of GFP-derived piRNAs. Percentage of ping-pong participants of GFP-derived piRNAs are indicated (see Materials and Methods). Relative nucleotide position (x-axis) indicates the nucleotide position relative to the reference sequences in the same scale. See also Supplemental Figures S3 and S4.
