Figure 3. Temporal expression of pdi-3 during post-embryonic development assayed by semi-quantitative RT-PCR. The pdi-3 transcript levels were compared with a constitutively expressed gene ama-1. The mRNA was isolated from synchronous C. elegans cultures. Hours post-L1 larval arrest are indicated. The data was expressed as the ratio ofpdi-3 to ama-1 transcripts. The RT-PCR was performed four independent times and the error bars indicate the mean +/- S.E.

Fig. 3. Expression pattern and rescue of cwn-2. (A-C)DIC images (top) and GFP images (bottom) showing expression of cwn-2::SL2::GFP. (A)Comma stage C. elegans embryo. Arrow indicates approximate location of the developing nerve ring. (B)Adult. Arrowhead, body wall muscle; arrows, intestine; P, pharynx. (C)High magnification of adult head. Arrow, SMD neuron; P, pharynx. Scale bars: 10μm. (D)Transgenic rescue of cwn-2 nerve ring defects by promoter::cDNA fusions. Nerve ring defects in each strain were scored at the L4 stage and normalized to defects in control siblings without the transgene (see Materials and methods). (E)Transgenic rescue of cwn-2 nerve ring defects by embryonic heat shock-induced cwn-2 expression. Controls are heat shocked cwn-2 animals without the hs::cwn-2 transgene. In D and E, error bars represent the s.e. of proportion. Asterisks indicate values different from controls at P<0.01 by Student's t-test.
