Figure 1


Fig. 1. Defects in anteroposterior embryonic patterning caused by loss of ik2 in the female germline. (A-C) Dark-field views of larval cuticle preparations at the end of embryogenesis from (A) wild-type and (B,C) bicaudal embryos from an ik21 germline clone female. (D-G) bicoid mRNA is localized to the anterior pole of wild-type embryos (D), ik2alice (E) and ik21 (F) mutant germline-derived embryos, and BicD1/BicD2 (G) embryos. (H-K) oskar mRNA localization at the posterior pole of a wild-type embryo (H), and at both the anterior and posterior poles of embryos produced by an ik2alice germline clone female (I), an ik21 germline clone female (J), and a BicD1/BicD2 mutant female (K). (L-N) nanos mRNA localization at the posterior pole of a wild-type embryo (L), and at both the anterior and posterior poles of embryos produced by an ik2alice germline clone female (M), and an ik21 germline clone female (N). Anterior to the left.
