Fig. 5. Summary of elt-5 and -6 reporter construct expression. The exon-intron structures of the elt-5 and -6 genes and approximate distances in kb are shown at the top. Short and long oval shapes represent GFP and lacZ-coding regions, respectively. +/- indicates weak expression. See Materials and Methods for a more detailed description of the constructs. See text for a description of the AB+MS lineage, seam and nervous system expression.
