—Ping–pong pathway signature. (A) Overlap probabilities of sense and antisense reads mapping to the genome and transposable elements (TEs). Overlap probabilities in all the different pH conditions are shown. (B) Depicted are base preferences of putative piRNA reads with ping–pong signatures mapping to the genome and TEs. The Y-axis represents the entropy score for the base bias. (C) Shown are putative piRNA reads aligned to a TE. Three regions with identified ping–pong signatures are highlighted. Green reads correspond to sense strand, and red reads to antisense strand.
