Fig. 2. Comparison of gonad defects with depletion of hlh-2, ppn-1 and gon-1. Nomarski microscopy was used to visualize the gonads of age-matched hermaphrodites that were hatched and grown on bacteria carrying RNAi-targeting constructs for hlh-2 (A), ppn-1 (B) and gon-1 (C). Arrows indicate lengths of paths taken by DTCs. Anterior is to the left, ventral is down in all images. Bars, 20 µm.
