Vectors for efficient and high-throughput construction of fluorescent drosophila reporters using the PhiC31 site-specific integration system.

The fruit fly Drosophila is a leading model system for the study of transcriptional control by cis-regulatory elements or enhancers. Here, we present a rapid and highly efficient system for the large-scale analysis of enhancer elements, site-specifically integrated into the Drosophila genome. This system, which is scalable for either small projects or high-throughput approaches, makes use of the Gateway cloning technology and the PhiC31 site-specific integration system, which allows the insertion of constructs at predetermined genomic locations.
