  Subcellular_localization: GFP was concentrated in the nucleus, the whole cell body including axons was also labelled.
  Type: Reporter_gene
  Pattern: GFP expression was observed in about 30 neurons of adult hermaphrodite worms. pida-1::GFP 7.6 expression was prominent in a subset of neurons in the head nerve ring, around the vulva, in a few cells in the ventral cord, and in the tail. Although the GFP was concentrated in the nucleus, the whole cell body including axons was labelled. Labeled processes included two lateral and one dorsal axon and a bundle of ventral axons running the length of the body, a pair of lateral axon bundles running from the head to the tip of the nose, and a pair of axons running from the anal region to the tip of the tail. GFP expression was observed as early as in late embryos. Larvae showed expression in the head and the tail, whereas GFP expression near the vulva and in the ventral cord was only seen in late L4 and adult animals. The expression pattern in dauer larvae was similar to that in other larval stages. Males exhibited many more GFP-expressing cells in the tail and additional cells in the head, and expression in the ventral cord differed from that observed in hermaphrodites. The GFP-expressing neurons in the hermaphrodite head were identified as ADE, ALA, ASI, ASK, AUA, ASG, AVH, and AVJ. Expression in ASG, AVH, and AVJ was not as bright as in other cells and was variable from individual to individual. A few other GFP-expressing anterior neurons could not be identified unequivocally. The fluorescent cells in the midsection of the animal were identified as the vulval motoneurons VC and HSN and the vulval uv1 cells. These are all hermaphrodite-specific and GFP expression was not observed until the late L4 larval stage. A lateral pair of neurons in the posterior half of the animal with weak GFP expression was identified as PDE. They possess ventrally directed processes entering the ventral nerve cord. In the preanal ganglion a pair of neurons with weak GFP expression was identified as PVP. Three pairs of GFP-expressing cells in the tail were identified as PHA, PHB, and PHC. Corresponding cells for the dorsal axon and a preanal structure have not been identified. The latter short process originates from the ventral nerve cord and peters out and terminates at the hypodermis.
  Remark: Reporter gene fusion type not specified.
    cgc6469 mentioned that this reporter gene is transcriptional fusion.
