Fig. 8 Changes in cellular rearrangements and patterns of gene expression during development of the vol^m712 mutants. (A,C,E,G,K) Wild type (wt); (B,D,F,H,I,J,L) vol^m712 mutant embryo. (A,B) Dissecting microscope images at the tail bud stage. Lateral view, dorsal toward the right. (E,F,I) Nomarski images at the tail bud stage, 30 minutes after the yolk plug closure in wild-type embryos. pl, polster; dcm, margin of deep cells; df, dorsal forerunner cells. (J) Dissecting microscope image of a vol^m712 mutant embryo at 10 hours. Embryo is in chorion, blastoderm is disintegrating. (C,D,G,H) Expression of gsc and ntl mRNA at 90% epiboly. (K,L) Expression of axial mRNA at 90% epiboly. nt, notochord expression domain of ntl; df, dorsal forerunner expression domain of ntl. Scale bars, 0.1 mm.
