Abstract
The Drosophila tracheal system consists of a widespread tubular network that provides respiratory functions for the animal. Its development, from ten pairs of placodes in the embryo to the final stereotypical branched structure in the adult, has been extensively studied by many labs as a model system for understanding tubular epithelial morphogenesis. Throughout these studies, a breathless (btl)-GAL4 driver has provided an invaluable tool to either mark tracheal cells during development or to manipulate gene expression in this tissue. A distinct shortcoming of this approach, however, is that btl-GAL4 cannot be used to specifically visualize tracheal cells in the presence of other GAL4 drivers or other UAS constructs, restricting its utility. Here we describe a direct-drive btl-nGFP reporter that can be used as a specific marker of tracheal cells throughout development in combination with any GAL4 driver and/or UAS construct. This reporter line should facilitate the use of Drosophila as a model system for studies of tracheal development and tubular morphogenesis.
期刊介绍：
Fly is the first international peer-reviewed journal to focus on Drosophila research. Fly covers a broad range of biological sub-disciplines, ranging from developmental biology and organogenesis to sensory neurobiology, circadian rhythm and learning and memory, to sex determination, evolutionary biology and speciation. We strive to become the “to go” resource for every researcher working with Drosophila by providing a forum where the specific interests of the Drosophila community can be discussed. With the advance of molecular technologies that enable researchers to manipulate genes and their functions in many other organisms, Fly is now also publishing papers that use other insect model systems used to investigate important biological questions.
Fly offers a variety of papers, including Original Research Articles, Methods and Technical Advances, Brief Communications, Reviews and Meeting Reports. In addition, Fly also features two unconventional types of contributions, Counterpoints and Extra View articles. Counterpoints are opinion pieces that critically discuss controversial papers questioning current paradigms, whether justified or not. Extra View articles, which generally are solicited by Fly editors, provide authors of important forthcoming papers published elsewhere an opportunity to expand on their original findings and discuss the broader impact of their discovery. Extra View authors are strongly encouraged to complement their published observations with additional data not included in the original paper or acquired subsequently.
