Expression pattern of exc-7::gfp in the OH16020 strain. exc-7 was endogenously tagged at its genomic locus with a gfp::3xflag tag (A). Embryonic expression (B) was observed in the excretory canal cell (arrow) and other unidentified cells (*). Broad expression was observed in L1 (C) and young adult head (D’), mid body (D’’), and tail (D’’’), including the excretory canal cell at both stages (arrow). In young adult, individual neurons expressing exc-7 were identified in the head (E’) and in the ventral nerve cord (E’’). All exc-7 expressing neurons are listed in panel (F) (grey box). Scale bar, 10 µm.
