Abstract

We undertook a deletional analysis of the gypsy retrotransposon in order to determine which sequences of the element are required for its mutagenic effect. We show that a phenotype indistinguishable from that of y2 flies can be generated by transforming y- flies with a construct containing the yellow gene and a gypsy element located at the same insertion site in yellow as found in y2 flies. When flies are transformed with similar constructs in which increasing amounts of the 5' transcribed untranslated region of gypsy have been removed, either a partial y2 revertant or a completely revertant phenotype is obtained. These results yield direct proof that the region of gypsy to which the su(Hw) protein binds is required for the generation of mutant phenotypes by this retrotransposon.
