Figure 2. blmp-1 Impedes Dorsal Migration of the Gonad.

(A) Schematic representation of gonadal migration programs of WT worms and various mutants as inferred from inspection. Arrowheads indicate positions of the dtcs. (B) Representative DIC images of WT and dre-1;daf-12 young adult worms grown on L4440 empty vector control or blmp-1 RNAi, respectively, showing one gonadal arm. Arrowheads indicate the position of the dtc. v = vulva. (C) blmp-1 depletion specifically suppresses gonadal migration defects of dre-1;daf-12 and dre-1;lin-29(n546) mutants. ***p<0.001 (ANOVA). Mean+SEM (n=3, 40 gonadal arms each). (D) Representative DIC images of 27 h post-hatching WT and blmp-1 mutant larvae staged by the vulval precursor cells (arrowheads, upper panel). Dtcs migrate precociously in the blmp-1 mutant (arrowheads, lower panel). (E) In blmp-1 mutants, as well as WT and dre-1;daf-12 mutants grown on blmp-1 RNAi dtcs turn dorsally ahead of time. ***<0.001 (ANOVA). Mean±SD.
ns = not significant. nd = not determined. Scale bars = 10 μm.
