Figure Caption

Fig. 1

brd2aMO morphants exhibit reduced brain, ill-defined MHB, and trunk defects. Representative embryos from morpholino injection studies conducted on a total of at least three clutches and 40–60 embryos per treatment. A) uninjected, B) 4 ng MO1 five-base-mismatch-injected, C) 4 ng standard control MOc-injected, D) and E) 4 ng brdMO-injected, and F) 4 ng brd2aMO2-injected embryos, are compared at prim 5–6 stages. MO1 and MO2 target non-overlapping regions in brd2a mRNA. Control embryos appear equivalent to wildtype, while both MO1 and MO2 morphants show the same characteristic reduced brain and ill-defined midbrain-hindbrain boundary (MHB) (arrows in D,E,F).
