Organization of the Drosophila head as revealed by the ectopic expression of the Ultrabithorax product.

Development (Cambridge, England) - 1 Dec 1991

González-Reyes A, Morata G

Abstract excerpt

By using a hsp70-Ubx fusion gene, we have ectopically expressed a Ubx product in the embryonic head primordia and studied the developmental effects on the larval head. We find that after high and persistent levels of Ubx product, the head is replaced by three (C1, C2 and C3) abdominal-like denticle belts. The C2 and C3 belts are the homeotic transformations of parasegments 1 and 2, respectively, while the C1 belt...
