  Type: Reporter_gene
  Pattern: In lines transformed with the cdd-1 reporter gene construct, faint staining was first detected in the egg, but the most intense staining was observed in the L1 and L2 stages. In the adult worm, transfection with the cdd-1 construct resulted in a higher incidence of `bagging' (eggs hatching within the parent), and in these animals intense staining of the newly hatched L1 in utero was observed. This phenotype was only observed in transformed worms. Staining in the L1 and L2 stages was confined to the gut cells and to the pharyngeal bulbs. Between the L2 and the L3 stages, most of the intestinal cells ceased to express the reporter gene, except for a few cells towards the tail of the worm. In later life cycle stages (L4 and adult), staining was largely confined to the pharynx and a cluster of cells at the tail of the worm.

  Remark: Ce-cdd-1 = C47D2.2
    The pattern of GFP expression constructs was very similar to that described for LacZ.
