Fig. 2. Neuronal expression of lin-11::GFP. (A) Schematic of the lin-11::GFP fusion gene, which includes 3.3 kb of promoter sequences and all exons and introns of lin-11. GFP is fused in frame prior to the STOP codon in the last exon. Exons encoding the two LIM domains are in red; exons encoding the homeodomain are in yellow. (B,C) Expression in the lumbar ganglion. (C) Schematic of the region shown in B. P, PVP; Q, PVQ; A, DVA; C, DVC; we cannot unambiguously identify whether the expressing cell is DVA or DVC. (D,E) Expression in head neurons. (E) Schematic of head neuron expression shown in D, including neurons out of the plane of focus. 1, AVA; 2, AVE; 3, ADF; 4, ASH; 5, ADL; 6, AWA (where expression is seen embryonically - see text); 7, ASG; 8, RIC; 9, AIZ; 10, AVG. Expression is also observed in additional unidentified cells (see text). Anterior is at left. Scale, 10 µm.
