Fig. 4. AVG and PVP cell type marker expression in lin-11 and unc-30 mutants. (A-D) AVG marker. Ventral aspect of the anterior end of the ventral cord with the retrovesicular ganglion. (A,B) odr-2::GFP, (C,D) glr-1::GFP in wild type (A,C) or lin-11(n389) (B,D). Marker expression is absent in AVG in lin-11(n389) (asterisks in B and D indicate where the AVG cell body should be). (E-H) Expression of odr-2::GFP in the preanal ganglion. (E) wild type; expression is strong in PVPR and PVPL and weakly seen in PVT. (F) unc-30(e191) mutant; expression in PVPR (asterisk) is missing. (G,H) expression in lin-11(n389). Expression levels in PVP neurons are either reduced (G) or expression is completely absent (H, asterisks). Scale bars: 5 µm in A,B,E-H; 10 µm in C,D.
