Myog mRNA or MyHC accumulation in uninjected, myod MO- or myog MO-injected embryos from wild type or shhatbx/+ in-cross. Dorsal flatmounts of 5 ss (A,B) or 10-15 ss (C) embryos. Bar: 100 μm. (A).
Myog mRNA is ablated by myod MO injection into wild type. (B)
Myod and myog MOs each delay adaxial myogenesis. (C)
Myod and myog, but not myf5, MOs ablate adaxial myogenesis in shhatbx392 mutants (21/79), but not from siblings.
