Figure 6. Localization of Dachs, Sple and Pk in abdominal pleura.

(A–G) Pleura of wildtype (A–C), ft8/ ftG-rv (D,E), dGC13 ft8/ dGC13 ftG-rv (F) and sple1/sple(G) pupae with clones of cells expressing GFP:Dachs (A,D), GFP:Sple (B,E,F) and GFP:Pk (C,G) (green). Posterior compartments are marked by hh-Gal4 UAS-mCD8-RFP (red). Anterior-posterior body axis is indicated at top. (H) Rose plots depicting polarization of GFP:Dachs, GFP:Sple or GFP:Pk in pleural cells of the indicated genotypes; anterior polarization is to the left and posterior polarization is to the right. For wild type and dachs mutants cells were scored separately in A and P compartments. For fat, ds, fat dachs, and ds dachs the anterior compartment was further subdivided into a front region (A1, anterior-most 8 cells), and the remainder of the A compartment (A*). For sple, 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); P compartment localization is summarized in Figure 6—figure supplement 1. Scoring of sub-regions of the A compartment in wild-type is shown in Figure 6—figure supplement 1. Apparent variations in cell size are mostly due to the flexibility of the pleura, which is easily stretched or compressed.

Figure 6—figure supplement 1.

(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.
