  Type: Reporter_gene
  Pattern: Fusion gene expression can be observed in early larvae in a small number of sensory neurons. In the head, the fusion gene expressing cells include the set of eight pairs of amphid neurons (ADF, ADL, ASE, ASG, ASH, ASI, ASJ, and ASK) situated in the bilaterally symmetrical lateral ganglia just in front of the second pharyngeal bulb. Amphids are two large sensilla located laterally in the head and have internal channels formed by the sheath and socket cells, that open to the outside through the cuticle. With the exception of ASE and ASG, the remaining six pairs concentrate the fluorescein dyes. In addition to these amphid neurons, a set of six inner labial(IL2) neurons, located in front of the central neuropil (nerve ring) and arranged in a 6-fold symmetry is stained in the young larval stages (L1-L2). The osm-3::lacZ expressing cells are most likely to be the set of IL2 neurons. During late larval (L3-L4) and adult stages, there is a complete disappearance of the staining in the set of amphid neurons. However, the fusion gene continues to express in the set of six IL2 (IL2DL, IL2DR, IL2L, IL2R, IL2VL, IL2VR) neurons. In the tail, through the entire postembryonic development i.e. in L1 to L4 larval and adult stages, a pair of PHA and PHB phasmid neurons are stained in the bilaterally symmetrical lumbar ganglia, located in the anterior region of the lumbar ganglia. Staining of amphid neurons is entirely absent in late larval and adult stages. Interestingly, there are no fusion gene expression during embryonic growth.
