... that in the fruit fly Drosophila , MEF2 is essential for the formation of mushroom bodies in the embryonic brain and for the normal development of wings in the adult. In embryos mutant for mef2 , there is a striking reduction in the number of mushroom body neurons and their axon bundles are not detectable...

...Hamed Rajabi; Veronica Schroeter; Shahab Eshghi; Stanislav N. Gorb ABSTRACT Dragonfly wings resist millions of cycles of dynamic loading in their lifespan. During their operation, the wings are subjected to relatively high mechanical stresses. They further experience accidental collisions which...

.... Within specific organs, local information is conveyed by signaling molecules that regulate organ growth and pattern. The mesothoracic (T2) wing and the metathoracic (T3) haltere of Drosophila represent a paradigmatic example of this coordination. The Hox gene Ultrabithorax ( Ubx ), expressed...

...Frederik Leys; Dominiek Reynaerts; Dirk Vandepitte ABSTRACT The stroke-cam flapping mechanism presented in this paper closely mimics the wing motion of a hovering Rufous hummingbird. It is the only lightweight hummingbird-sized flapping mechanism which generates a harmonic wing stroke with both...

...María F. Organista; Jose F. De Celis Summary The expression of the spalt genes is regulated by the Decapentaplegic signalling pathway in the Drosophila wing. These genes participate in the patterning of the longitudinal wing veins by regulating the expression of vein-specific genes...
