Expression pattern of a lon-8 transcriptional reporter. (A) Schematic representation of the reporter construct (see text for details). The portion of the first exon that is removed is indicated with a dashed line. The gfp coding sequence is shown in green. (B) to (G) Differential interference contrast (DIC) microscopy and corresponding fluorescence micrographs. Bar is 20 μm. (C) A comma stage embryo expressing lon-8::gfp in the nuclei of hyp4. (D), (E) A 1.5 fold stage embryo expressing lon-8::gfp in hyp4 and hyp7 nuclei. (F), (G) An L1 larva expressing lon-8::gfp in hyp4 and the hyp7 syncytium.
