Some TE loci produce a prevalence of 29-nt sized piRNAs. (A) The upper panel is a heat map that indicates the strand bias of cloned piRNAs derived from the TEs. The bottom panel is a heat map that indicates the relative frequency of 29 vs 27-nt TE piRNAs as a ratio. Transposons are grouped into long terminal repeats (LTR), long interspersed nuclear elements (LINE), inverted repeats (IR) and rolling circles (RC) elements. (B) Read size distribution of sense and antisense piRNAs on the BEL8 family of LTR elements. (C) Read size distribution of sense and antisense piRNAs on the COPIA3 TE family of LTR elements. (D) Read size distribution of sense and antisense piRNAs on the TC1N-2 TE family of IR elements.
