Figure 3. Receptor systems mediating planar polarity in the germband.

Figure 3.

(A) Schematics of Toll receptors, Tartan, and Ten-m (not to scale). (B) Toll-2, Toll-6, and Toll-8 are expressed in staggered striped patterns in the germband. C) tartan (purple) is expressed in stripes and Ten-m protein (green) is enriched at the stripe borders. (D) The germband is organized into double-parasegment units, each made up of seven or eight columns of cells. Even parasegments (cells 1–4), odd parasegments (cells 5–8). Wingless-expressing cells are shown in gray. (E) Toll receptor expression within the double-parasegment unit. (F) Tartan expression and Ten-m localization within the double-parasegment unit. Ten-m is enriched at compartment boundaries and is absent from the membrane in Tartan-positive cells.
