1. Effects of overexpressing pk on polarity of cells in which either the Stan/Fz system (stan–) or the Ds/Ft system is broken (ft– d–), or both are broken (ft– d– stan–).
Effects of overexpressing pk on polarity of cells in which either the Stan/Fz system (stan–) or the Ds/Ft system is broken (ft– d–), or both are broken (ft– d– stan–). Phenotypes of A compartments (A-C,E,G,H,J) and P compartments (D,F,I,K). In the A compartments, generalised overexpression of pk changes the polarity of the anterior region of wild-type, stan– and ft– d– cells (A,G,H). In the P compartments, the region that normally points anteriorly in ft– d– points posteriorly (as in the wild type) when pk is overexpressed (I). Ubiquitous Pk appears to have no effect on ft– d– stan– in either A or P compartments (compare E,F,J,K). Compare Fig. S4 for expression of pk in d– flies.
