Comment: notum
In the wing pouch, EcollacZvn-rF264 is expressed as a broad discontinuous stripe straddling the A/P boundary in the L3 and L4 intervein region and also in the hinge and the notum, in a pattern similar to that of vn transcript. In contrast to vn transcript expression, EcollacZvn-rF264 is expressed in the presumptive hinge and notum of the haltere disc.
