Figure 4. Expression patterns of
egl-4 promoter::gfp/nls fusions. Larvae (A-E,G) and an embryo (F) expressing green fluorescent protein (GFP) under promoter a (5.5 kb) (A-F) or promoter b (1.4 kb) (G). B and C are higher magnification images of head neurons (B) and a part of hypodermis (C) of the worm shown in A. Stages are L3 (A-C), L4 (G), young adult (D,E) and embryo (F). A-C, E and G are lateral views, and D is a ventral view. The images were obtained with a Zeiss LSM-410 (A-C,G) or LSM-510 (D-F) confocal microscope. Scale bars: 50 um (A,D,E,G) and 20 um (B,F).
