The development of indirect flight muscle innervation in Drosophila melanogaster
We have examined the development of innervation to the indirect flight muscles of Drosophila. During metamorphosis, the larval intersegmental nerve of the mesothorax is remodelled to innervate the dorsal longitudinal muscles and two of the dorsoventral muscles. Another modified larval nerve innervates the remaining dorsoventral muscle. The dorsal longitudinal muscles develop using modified larv...
متن کاملPrepattern genes and signaling molecules regulate stripe expression to specify Drosophila flight muscle attachment sites
In Drosophila, muscles attach to epidermal tendon cells specified by the gene stripe (sr). Flight muscle attachment sites are prefigured on the wing imaginal disc by sr expression in discrete domains. We describe the mechanisms underlying the specification of these domains of sr expression. We show that the concerted activities of the wingless (wg), decapentaplegic (dpp) and Notch (N) signaling...
متن کاملAconitase and Developmental EndPointsasEarly IndicatorsofCellularToxicity Induced by Xenobiotics in Drosophila Melanogaster
Background: In this study, the toxicity of the different xenobiotics was tested on the fruit fly Drosophila melanogaster model system. Methods: Fly larvae were raised on food supplemented with xenobioticsat different concentrations (sodium nitroprusside (0.1-1.5 mM), S-nitrosoglutathione (0.5-4 mM), and potassium ferrocyanide (1 mM)). Emergence of flies, food intake by larvae, and pupation h...
متن کاملSelection for abdominal tergite pigmentation and correlated responses in the trident: a case study in Drosophila melanogaster
In Drosophila melanogaster, abdominal tergite pigmentation and the appearance of a trident-shaped thoracic pattern exhibit similar biogeographical variation and sensitivity to temperature. These pigmentation traits may be under common selection pressure in natural populations or may be genetically correlated. To investigate the nature of this interaction, replicated populations of D. melanogast...
متن کاملNatural variation of ebony gene controlling thoracic pigmentation in Drosophila melanogaster.
We identified the causal genetic variation for the difference in the thoracic trident pigmentation intensity between two wild-derived strains of Drosophila melanogaster. It was found to be the difference in expression level of ebony, which codes for an enzyme in the melanin-synthesis pathway and has pleiotropic effects on vision and behavior.
