WormMine: ExpressionPattern Expr7888

• Pattern: In all lines, GFP expression was observed exclusively in the M4 pharyngeal neuron from the 2-fold stage [~450 min post first cleavage (pfc)] through adulthood. In earlier embryos prior to pharyngeal formation, strong and reproducible GFP was also observed in a cell called ABalaappa beginning at 172 min pfc and continuing in the daughters of this cell. The anterior daughter of this cell undergoes pro- grammed cell death, whereas the posterior daughter (called ABalaappap) continues to express GFP until at least 350 min pfc, before dividing to produce the AVAR ventral cord interneuron and the OLQsoVR socket cell. Weak and variable expression was also observed in other cells including ABalapap(a/p).
