Representative examples of X-gal stained embryos at tailbud stages following C. intestinalis (B), P. mammillata (C), P. fumigata (D), or A. mentula (E) embryo electroporation with C. intestinalis or P. mammillata CRMs. All shown CRMs for the genes Msx (i), Ascl.b (ii), Klf1/2/4 (iii), Nkxtun3 (iv), Tox (v), and Dlx.c (vi) are active in VDML in their species of origin. The name of the electroporated CRM is indicated on each picture. Details for each experiment can be found in Figure 6—figure supplement 1 and Figure 6—figure supplement 2. Embryos are shown in lateral view with dorsal to the top and anterior to the left. Scale bar: 50 μm.
