Developmental consequences of unrestricted expression of the abd-A gene of Drosophila.

Mechanisms of development - 1 Jun 1994

Sánchez-Herrero E, Guerrero I, Sampedro J, González-Reyes A

Abstract excerpt

The abdominal-A (abd-A) gene of Drosophila specifies abdominal segments two through eight (A2-A8). We have found that the uniform expression of the abd-A protein under heat shock control transforms embryonic segments anterior to the abd-A domain into an abdominal segment of the A2-A6 type. Posterior abdominal segments and telson undergo little or no transformation, that is, the abd-A product is phenotypically...
