Figure 6
Ct-piwi1 expression patterns in one week post-metamorphic juveniles. All panels are ventral views with anterior to the left. Abbreviations: mgp, male gamete precursor; pgz, posterior growth zone. Dotted lines in C and D indicate the segment boundaries of the 5th and 6th segments. (A) Male juvenile worm. (B) Female juvenile worm. (C) In a male juvenile, Ct-piwi1 expression is in the PGCs in the fifth and sixth segments (arrow), and bilaterally symmetrical male gamete precursors at the boundary of the seventh and eighth segments. (D) In female juveniles, expression is in the PGCs in the fifth and sixth segments (arrow). (E, F) A close-up views of expression in the posterior growth zone in a male (E) and female (F) juvenile. Scale bar, 50 μm for all panels except A and B, which are 100 μm.
