As part of the mating ritual, males of Drosophila species produce species-specific courtship songs through wing vibrations generated by the thoracic musculature. While previous studies have shown that indirect flight muscles (IFM) are neurally activated during courtship song production, the precise role of these muscles in song production has not been investigated. Fortunately, IFM mutants abound...
Recent genome-level innovations have enabled the identification of the entire cadre of genes that are expressed in specific tissues at particular developmental times. However, to be informative as to how individual cell types develop, this process relies upon the successful and efficient purification of cells for a particular tissue. Here, we describe a method to isolate cardiac cells from Drosophila...
The Drosophila heart has become an exciting model for elucidating the molecular basis for cardiac function in higher organisms. To complement the genetic approaches that have recently identified an array of genes essential for cardiac function, we developed a method to obtain optimal semi-thin cross sections of embryonic, larval, and adult fly hearts in a desired orientation. A procedure for fluorescent...
Myoblast fusion in the Drosophila embryos is a complex process that includes changes in cell movement, morphology and behavior over time. The advent of fluorescent proteins (FPs) has made it possible to track and image live cells, to capture the process of myoblast fusion, and to carry out quantitative analysis of myoblasts in real time. By tagging proteins with FPs, it is also possible to monitor...
