Figure 4


Fig. 4. svb function is necessary for the maintenance of epidermal SoxN and Dichaete expression. (A-H) Anti-SoxN stainings (A-D) and anti-Dichaete (anti-D) stainings (E-H) of wild-type (WT) and svb1 mutant embryos. Wild-type (A) and svb1 mutant (B) stage-13 embryos; note that there is no appreciable difference between wild-type and svb1 mutant embryos, indicating that svb is not required for the establishment of the SoxN expression domain. Wild-type (C) and svb1 mutant (D) stage-16 embryos. (D) Notice the severe reduction of SoxN expression, indicating a role for svb in the maintenance of SoxN expression. Wild-type (E) and svb1 mutant (F) stage-13 embryos; notice that there is no appreciable difference between wild-type and svb1 mutant embryos, indicating that svb is not required for the establishment of the Dichaete expression domain. Wild-type (G) and svb1 mutant (H) stage-16 embryos. (H) Notice the reduction in Dichaete expression, indicating a role for svb in the maintenance of Dichaete expression.
