Fig. 6. msk loss-of-function does not affect Atonal or pMAPK in the
furrow. (A-F) Third instar eye-imaginal discs with msk
null clones (outlined), stained for (A,D) GFP, which negatively marks the
clones, (B) pMAPK, (C) pMAPK (red) and GFP (green), (E) Atonal, and (F) Atonal
(red) and GFP (green). Anterior is to the right, scale as indicated in A.
Atonal and pMAPK expression is normal in clones (arrows).
