  Expression_data: Life_stage: WBls:0000003
    Anatomy_term: WBbt:0005812 Certain
  Type: Reporter_gene
  Pattern: exc-7::gfp construct shows no visible expression in the excretory canals of adults or larvae. No expression was seen until shortly before the birth of the excretory cell, approximately midway through embryogenesis (270 min after first cell cleavage). At this point, four cells in the head showed expression of the fusion construct. Expression was seen in the excretory cell shortly after its birth. This expression was weaker than that seen in surrounding neural tissue, and continued for only about an hour, until the approximate time when internal organs such as the intestines and pharynx become clearly delineated by basement membranes. exc-7 expression in the canals completely disappeared before the 1.5-fold stage, approximately 420 min after first cell cleavage, still 6 h before hatching. Little or no expression was seen in the developing hypodermis or intestine during the period of continuing morphogenesis, but strong expression was observed throughout the developing pharynx and nerve ring and in two nerve cells of the preanal ganglion.
  Remark: Reporter gene fusion type not specified.
