The Ultrabithorax gene of Drosophila and the specification of abdominal histoblasts.

Developmental biology - 1 Aug 1991

Frayne E G, Sato T

Abstract excerpt

Separation of the imaginal and larval developmental pathways in Drosophila occurs early in embryogenesis, resulting in the formation of imaginal discs and abdominal histoblast nests along the larval body wall. The dorsal and ventral histoblast nests within the first abdominal (A1) segment are shown not to be segmentally homologous with the metathoracic (T3) haltere and leg discs, respectively, since they occur at...
