Fig. 1. Post-embryonic phenotype of par-3(RNAi) worms. Worms carrying AJM-1::GFP were collected after 48 hours of growth on bacteria producing par-3 dsRNA (B,B') or control bacteria (A,A') and stained with DAPI (A,B). Spermathecae were visualized by AJM-1::GFP (arrows in A',B'). The small condensed DNA signals represent the sperm nuclei (arrows in A,B) that are present in the spermathecae of control worms (A) but are restricted to the proximal ovary of par-3(RNAi) worms (B). Endomitotic oocyte nuclei (B) and normal nuclei (A) are indicated by arrowheads in A, B. Scale bar: 10 µm.
