Split-QF system for fine-tuned transgene expression in Drosophila
The Q-system is a binary expression system that works well across species. Here we report the development of a split-QF system that drives strong expression, is repressible by QS and inducible by quinic acid. The split-QF system is fully compatible with existing split-GAL4 and split-LexA lines for advanced intersectional experiments, thus greatly expanding the range of possible anatomical, physiological and behavioural assays in Drosophila.
