show Abstracthide AbstractHere, we examine neuronal lncRNAs in a model system that offers enormous advantages for deciphering their functions: the Drosophila olfactory system. This system is numerically simple, its neurons are exquisitely well-defined, and it drives multiple complex behaviors. We have undertaken the first comprehensive survey of linear and circular lncRNAs in the Drosophila antenna, and have identified a wealth of lncRNAs enriched in it.
