Fig. 5. Nasonia hunchback expression during blastoderm development. (A) Timeline of Nasonia embryogenesis at 28°C. The embryos in B and C are from the same two-hour egg collection as the embryos in D and E. (B) mRNA expression soon after the nuclei begin dividing at the surface of the embryo. (C) Anterior nuclear gradient of protein expression after the nuclei begin dividing at the surface of the embryo. (D) The next phase of mRNA expression after that shown in B, localized in a posterior and central domain. (E) Anterior Hunchback domain with sharper boundary several cell cycles later than is shown in C. (F,G) Subsequent mRNA and protein during early cellularization. (H,I) mRNA and protein expression shortly before gastrulation.
