GFP expression patterns driven by Promoterome reporter gene fusions. The ceh-32 Promoterome insert drives GFP expression in specific nerve cells in the head of a larva (A) and adult (B), and in anterior cells of an early embryo (C), in the C. elegans strain UL2623. An adult's anterior body wall muscle cells express GFP under the direction of the ceh-33 Promoterome insert in UL1265 (E). Additional head body wall muscle cells, as well as tail body wall muscle cells, express GFP driven by the ceh-34 Promoterome insert in larvae and adults of UL1512 (F). The unc-39 Promoterome insert drives GFP expression in specific nerve cells in an adult's head of UL2387 (G). The DIC images D and H correspond to fluorescent micrographs C and G respectively. All images were captured at 200× magnification, apart from C and D, captured at 400×, and F, captured at 100×.
