(M-P) Localization of the endogenous GFP::TOCA-1 reporter zh110 in wild-type (M) and unc-6(ev400) mutants (O and P) before (M and O) and after (N and P)lumen formation. (M') and (O') show yz projections of the lateral VulF membranes. The inset in (O) shows the displaced AC in the unc-6(ev400) mutant in a differentfocal plane.
(M-O) The epg-5 reporter is expressed ubiquitously in embryos (N) and widely in larvae (O). EPG-5 is cytoplasmic. (M) Nomarski image of the embryo in N.
(O-W) Expression ofGFP in hermaphrodite gonads with no transgene (O-Q), Punc-87A::GFP (R-T), or Punc-87B::GFP (U-W) was examined by immunostaining of dissected gonads for GFP (O, R, and U) and MYO-3 as a marker of myoepithelial sheath (P, S, andV). Merged images are shown in Q, T, and W (green, GFP; red, MYO-3; blue, DNA [not shown as individual images]). Scale bars, 100 um (whole worms; A, B, I, and J), 20 um (magnified tissues; C-H,K-N), 50 um (dissected gonads; O-W).
PLK-1 cytoplasmic asymmetry in early C. elegans embryos. Merged immunofluorescence micrographs of DAPI staining (red) with anti-PLK-1 (A-F) staining (green). (G-L) GFP fluorescence of GFP::PLK-1PBD. (O,P) GFP fluorescence of GFP::PLK-1FL (O). Closed and open arrowheads indicate the germline blastomere and its somatic sister, respectively. Stages of embryos in A-L are marked to the left; O, 2C. Scale bar: 10 μm.
FIG. 2. Temporal pattern of klf-1 gene expression as determined by real-time PCR. Note that Ce-klf-1 transcripts are low in embryos but increased several folds in the larval stages and decreased again in adult.
A) Schematic of primer design approach; the deletion is red. B) Genomic map of the numr-1 and -2 deletion. C-F) Real-time PCR amplification and melt curves for inner primers (C-D) and outer (E-F) primers.
(B) The expression levels of mtssb-1 during development weremonitored with real-time quantitative RT-PCR as compared with the expression level of an elongation factor eft-2. Relative ratio of each expression was calculated using the adult expression levels.
Fig. 3. Real-time PCR analysis of the gene expression level of rrc-1. The mRNA values for each group were normalized with the reference gene, b-actin. Results are expressed as mean values of the group ± SD. n = 3 in each group.
