  Type: Reporter_gene
  Pattern: Embryonic GFP expression was identical to that seen with anti-INA-1 antisera: ubiquitous expression beginning at gastrulation, with more pronounced expression in the developing pharynx. Because all cells of the embryo expressed moderate levels of GFP during the migrations of the CAN, ALM, and HSN neurons, it is unable to detect any changes in the levels or localization of GFP in these neurons during their migrations. In L1 larvae, however, most cells no longer expressed GFP, making expression of the GFP reporter in the migratory Q neuroblasts and their descendants quite distinct. In L1 larvae, these cells turned on GFP as they began their migrations, and then turned it off when the migrations were completed. In older larvae, some of the Q-derived neurons turned GFP back on. Other migrating cells in larvae also expressed GFP, notably the distal tip cells of the hermaphrodite gonad and the P cells. Cells in organs undergoing morphogenesis, such as the hermaphrodite uterus and vulva and the male tail, also expressed high levels of GFP. Finally, the GFP reporter was also expressed in many nonmigratory neurons, including neurons in the head, tail, and ventral nerve cord, at various times during larval and adult stages.
