Gerlitz, O; Nellen, D; Ottiger, M; Basler, K (2002). A screen for genes expressed in Drosophila imaginal discs. International Journal of Developmental Biology, 46(1):173-176.



The development of Drosophila imaginal discs serves as a model system to understand how genes determine the shape and size of an organ. The identification of genes involved in this process is an important step towards this goal. Here we describe a P-element based enhancer trap screen for genes expressed in the larval imaginal discs. Our aim was to establish a large collection of enhancer trap lines each showing expression of Gal4 in imaginal discs. To this end, we improved the well established P-element vector pGawB in order to obtain higher in vivo transposition frequencies. In addition we chose an F1-screening approach using UAS-GFP as a reporter gene. This system permits the efficient screening of larval and pupal stages of living animals and the detection of imaginal gene expression patterns through the transparent cuticle. The procedure has been optimized for high-throughput. 2'000 P-element insertions have been established which exhibit expression in imaginal discs.
