Fig. 1. GABAergic RME neurons. (A) The cell lineage and morphology of RME cells. X, dying cells. (B) P_unc-25GFP expression. For wild type (labeled as juIs76) and ju145, two focal planes are shown, one on RMED/V, the other on RMEL. Schematic illustrations are shown on the right. Asterisks denote the position of the processes from the RMED and RMEV neurons; arrowheads point to the ectopic process from RMEL in ju145. (C). Anti-GABA staining reveals defects in ahr-1 identical to those shown in B. Two focal planes are shown, one on RMED/V, the other on RMEL. Arrow points to the ectopic process from RMEL in ju145. Scale bar: 50 µm.
