Whole-mount in situ hybridization showing the expression pattern of DBL-1-regulated genes. Wild-type (A–I, M, Q, and U), dbl-1 (J, N, R, and V), sma-2 (K, O, S, and W), and lon-2 (L, P, T, and X) larvae were hybridized with digoxigenin-labeled RNA probes to localize the expression of each cDNA clone. The names of the cDNA clones used for probe synthesis are indicated above (A–H) and to the left (I–X) of the figures.
