A) Schematic illustrating the orientation of hairs and approximate gradients of Ds, Fj and Hh expression in the abdomen (
Casal et al., 2002;
Struhl et al., 1997). (
B) Rose plots depicting polarization of GFP:Sple or GFP:Pk in pleural cells of the indicated genotypes. Additional wild-type analysis is for comparison to mutants shown in
Figure 6; anterior polarization is to the left and posterior polarization is to the right. For GFP:Sple the anterior compartment was subdivided into a front region (A1, anterior-most 8 cells), and the remainder of the A compartment (A*). For GFP:Pk the A compartment was subdivided into a front region of 5 cells (Af), a back region of 10 cells (Ab), and a middle region comprising the rest of the compartment (Am). (
C) Pleura of
dGC13 sple1/ dGC13 sple1 pupa with clones of cells expressing GFP:Pk (green). Posterior compartments are marked by hh-Gal4 UAS-mCD8-RFP (red). Anterior-posterior body axis is indicated at top.
