Fig. 5. The loss of PAR-1 alters the distribution of MT plus-ends. (A) A par-1 clone in a stage 10 egg chamber in which the MT minus end marker, Nod:ß-Gal, is expressed in the follicle cells. Nod:ß-Gal localises apically in both mutant and wild-type cells. (B): A par-1 clone in a stage 10 egg chamber in which the MT plus-end marker, Kin:ß-Gal, is expressed in the follicle cells. Kin:ß-Gal localises basally in wild-type cells, but accumulates in the centre of mutant cells. GFP, green; ß-Gal, red. (C) -Tubulin stainings in wild-type follicle cells (WT) show MTs extending from the apical to the basal cortex, with a lower density along the basal membrane. par-1 mutant follicles cells (par-1^-) show some MTs along their basal membrane.
