Fig. 4. The sma-3 expression with tissue-specific promoters. Worms
carrying each array are picked during L4 stage and photographed 24 hours
later. The A1-H1 photos (first and third columns) show the overview of the
expression pattern and the body size. The A2-H2 photos (second and fourth
columns) focus on the region that has strong GFP expression. The tissue
specific promoter used in each set is indicated in the A1-H1 photos. Scale
bar: 0.5 mm in A1-H1 photos.
