In situ hybridization analysis of
pgl-1 transcripts in whole-mount wild-type worms at different developmental stages. Anterior is left, ventral is down. Wild-type worms were hybridized with cDNA probes for
pgl-1. Developmental stages of worms are indicated: L1-L4, four larval stages; YA, young adult stage (before egg laying); A, adult stage (containing embryos). Bars, 50 um.
