Maternal deposition and levels of TE-derived small RNAs in D. virilis strains and hybrids. (A) Maternal deposition of TE-derived small RNAs in strain 160. The values were normalized to the levels of small RNA measured in ovaries of each strain. (B) Relative proportion (%) of various TE-derived small RNAs in somatic tissues (carcasses) and germ line (ovaries). (C) Maternal effect of piRNAs deposited into embryos on the levels of piRNAs in the gonads of F1 hybrids between strain 9 and strains containing multiple Penelope copies (160, 140, and Argentina). (i) Levels of Penelope-derived piRNAs in the ovaries of the three strains; (ii) levels of Penelope-derived piRNAs in the testes of the three strains; (iii) relative levels of Penelope-derived piRNA deposited into embryos from crosses involving strain 9, which lacks Penelope and strains carrying multiple Penelope copies (160, Argentina, and 140). Ratios of piRNA levels are shown comparing crosses with strain 9 fathers to crosses with strain 9 mothers. (iv, v) Relative levels of Penelope-derived piRNAs in F1 gonads of crosses involving strains 160, 140, and Argentina with the indicated strain 9 parent.
