Figure 4. JAK/STAT signalling and fold formation.

Figure 4

Proximal (P), medial (M) and distal (D) folds are labelled. (A) Wild type third instar wing imaginal discs showing the pattern of 10xSTATGFP reporter activity (green), FasIII (red) and DNA (blue). The approximate position of the XZ sections shown in B–E is indicated by the dotted line. (B) An XZ section through the lateral wing folds of wild type third instar wing imaginal disc showing F-actin (red in B and white in B’) and the 10xSTATGFP reporter (green in B and white in B”). (C–E) XZ sections through third instar wing imaginal discs of males hemizygous for the oso allele stained to visualise F-actin (white), and hence disc structure. The P fold is reduced in depth in C and D (arrows) and is missing completely in E.
