Fig. 2. Loss of sax function expands pMad distribution in wing
discs. Intensity plots (A,B,C,D) of the
relative fluorescence (y-axis) of
(A',B',C',D') pMad (red)
across equivalent regions of the wing pouch (broad white line). (A) Wild type,
(B) sax4/Df(2R)H23, (C) Df(2R)H23/+ and (D)
gbb1/+.
(A'',B'',C'',D'') brk
expression (green) (brkX47-LacZ). Thin white lines mark
the extent of brk repression from the center of wing pouch. All
images were captured using the same microscope settings.
