Figure 5. In situ hybridization analysis of
pgl-1,
pgl-2, and
pgl-3 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 (left),
pgl-2 (middle), and
pgl-3 (right). Developmental stages of worms are indicated in each: L1-L4, four larval stages; YA, young adult stage (before egg laying); A, adult stage (containing embryos). Bars, 50 μm. Note that the magnification for
pgl-1 L1 and L2 is twice that used for the rest of the image.
