Expression Pattern :

Pattern  Except for an earlier onset of GFP expression from both evpPRII.67 and evpPRII.75, all reporters displayed very similar expression patterns. Embryonic GFP expression reported by evpPRII.14 is first visible at approximately 240 minutes of development and is ubiquitous, a pattern that persists until hatching. At the beginning of each larval stage, dividing seam cells express mab-20::GFP, as do both daughter cells in males and hermaphrodites. After the anterior daughter fuses with surrounding hyp7, mab-20::GFP expression is downregulated or shut off in the both daughters. Other hypodermal expression is not evident in males or hermaphrodites. Other cells that express mab-20::GFP in hermaphrodites include the hermaphrodite-specific neurons at the L4 stage, vulva cells A to F throughout development, the migrating distal tip cells during the L4 stage, and several unidentified neurons within the nerve ring and ventral nerve cord. Expression in males include cells in the posterior ganglia, the migrating male linker cell beginning at the L3 to L4 transition, and the same nerve ring and ventral nerve cord expression observed in hermaphrodites. About 35 hours after hatching, mid-L3 males express mab-20::GFP in the 9 R(n) cells that give rise to the ray precursor clusters. Interior neuronal ganglia also express lower levels of mab-20::GFP at this stage. At 38-40 hours, when ray papillae are just visible, the 9 R(n)s and their descendents express mab-20::GFP. However, the underlying neural ganglia express the same level of GFP as the ray precursors at this stage. This pattern of expression continues until adulthood. Primary Identifier  Expr1034
