Expression patterns of Nanos , Piwil1 , and Tdrd7 homologs in B. belcheri and B. japonicum during embryonic development. (A) Bb-Nanos and Bj-Nanos expression patterns. (B) Bb-Piwil1 and Bj-Piwil1 expression patterns. (C) Bb-Tdrd7 expression patterns. One-cell-, two-cell-, 64-cell-, and blastula-stage embryos are in lateral view with the animal side up and vegetal side down; four-cell-stage embryos are in vegetal view; mid-gastrula and late-gastrula-stage embryos are in left side view with the anterior to the left. Black arrowheads indicate the aggregated maternal mRNA, while hollow arrowheads indicate the zygotic expression around the blastopore during the gastrula stage. Scale bars, 50 μm, can be applied to embryos in the same developmental stage.
