Fig. 2. Expression of dMyc in the ovary, and morphology of dm2 germline clones. (A) In wild-type ovaries, dMyc is present in the nuclei of germline and somatic cells at most stages of oogenesis. (B,C) Nuclear dMyc is absent from follicle cells homozygous for dm1 (white outlines), identified by their blue color in the hGFP/DAPI overlay. (D,E) Nuclear dMyc is also absent from follicle cells homozygous for dmPG45 (white outlines; identified by their blue color in the hGFP/DAPI overlay). (F,H) Egg chambers with a dm2 mutant germline (arrowhead), identified by the absence of hGFP, appear smaller than normal, on the basis of their position in the ovariole. (G,I) Oocyte specification is not apparently affected in dm2 mutant germ cells. The oocyte nucleus labels faintly with DAPI (arrowhead), and is positioned at the posterior of this stage 4 egg chamber.
