Fig. 5. The role of individual Tudor domains for germ cell formation. (A) Cellular blastoderm stage embryos from wild-type (wt), tud mutant (A36, A7, B42 and tud¹) and tud¹ females that express the mini-tud 3 transgene; anti-Vasa antibody marks germ cells. (B,C) In situ experiments showing gcl (B) and pgc (C) RNA staining in wild type and different tud mutant embryos generated by females transheterozygous for the respective tud allele and Df(2R)Pu^rP133. For all panels, anterior is to the left and dorsal is up.
