The study of imaginal discs in the fruit fly Drosophila melanogaster led to the discovery of homeotic mutations such as antennapedia, where the developmental fate of a disc could sometimes change. It is of interest to entomologists that the kinds of developmental switches that occur are very specific (leg to antenna, for instance).
In invertebrates, the wing imaginal disc of Drosophila provides an excellent model for the study of compartments. Although other tissues , such as the abdomen, [ 5 ] and even other imaginal discs are compartmentalized, much of our understanding of key concepts and molecular mechanisms involved in compartment boundaries has been derived from ...
Decapentaplegic (Dpp) is a key morphogen involved in the development of the fruit fly Drosophila melanogaster and is the first validated secreted morphogen. [1] It is known to be necessary for the correct patterning and development of the early Drosophila embryo and the fifteen imaginal discs, which are tissues that will become limbs and other organs and structures in the adult fly.
Drosophila melanogaster can be distinguished from related species by the following combination of features: gena ~1/10 diameter of eye at greatest vertical height; wing hyaline and with costal index 2.4; male protarsus with a single row of ~12 setae forming a sex comb; male epandrial posterior lobe small and nearly triangular; female abdominal ...
Ernst Hadorn (31 May 1902–4 April 1976) was a Swiss developmental biologist.He developed techniques for imaginal disc transplantation in Drosophila, leading to technique for the production of fate maps, and studied the organization of mature discs.
Cytonemes with a diameter of approximately 0.2 μm and as long as 80 μm have been observed in the Drosophila wing imaginal disc. [1] The term cytoneme was coined to denote the presence of cytoplasm in their interior (cyto-) and their finger-like appearance (-neme), and to distinguish their role as signaling, rather than structural or force ...
Drosophila embryogenesis, the process by which Drosophila (fruit fly) embryos form, is a favorite model system for genetics and developmental biology. The study of its embryogenesis unlocked the century-long puzzle of how development was controlled, creating the field of evolutionary developmental biology . [ 1 ]
In drosophila the transcription factor Scalloped is involved in the development of the wing disc, survival and cell growth. [23] Finally in Xenopus it has been demonstrated that the ortholog of TEAD1 regulates muscle differentiation.
