Fig. 3. Ventral cord defects in lin-11(n389) mutants. (A-D) Wild type, ventral cord with interneurons and motoneurons labeled with different GFP variants: (A-C) single color marker, (D) overlay. (E-H) Ventral cord defects in lin-11(n389), same labels and arrangement as in A-D. Arrowheads indicate axons inappropriately crossing the ventral midline. (I,J) Wild type (I) and lin-11(n389) mutant (J), DA/DB motoneurons labeled. Arrowheads in J indicate commissures growing out on the wrong side. All animals are shown from a ventral aspect with anterior towards the left. Scale bars: 10 µm in A-H; 20 µm in I,J. Markers shown are unc-129::CFP (dark blue in A,D,E,H, gray in I,J), glr-1::GFP (green in B,D,F,H), unc-47::DsRed (red in C,D,G,H).
