P-element transposition is limited to the germ line because the element's third intron is only spliced in germ line cells. We show that a 240-bp fragment containing this 190-bp intron can confer germ line specificity when placed in the context of another gene. We find that the cis-acting regulatory sequences required for germ line regulation map near to, but not at, the 5' or 3' splice junctions.
