Reduced O-GlcNAc levels in sxc^H537A mutants does not affect Hox gene expression pattern. Stage 13–14 WT (w¹¹¹⁸; A, C, and E) or sxc^H537A (B, D, and F) embryos were immunostained with anti-Scr (A and B), anti-Ubx (C and D), or anti-Abd-B (E and F) antibodies. The expression domains of all of these Hox genes tested remained unchanged. All of the embryos are aligned along the anterior-posterior axis with the anterior to the left. Embryos are depicted in either dorsal (A and B) or lateral (C–F) views.
