Transposons are mobile genetic elements that have made a large contribution to genome evolution in a largely species-specific manner. A wide variety of different transposons have invaded genomes throughout evolution, acting in a first instance as 'selfish' elements, whose success was determined by their ability to self-replicate and expand within the host genome. However, their coevolution with the host has created many crossroads between transposons and the regulation of host gene expression. Transposons are an abundant source of transcriptional modulatory elements, such as gene promoters and enhancers, splicing and termination sites, and regulatory non-coding RNAs. Moreover, transposons have driven the evolution of host defence mechanisms that have been repurposed for gene regulation. However, dissecting the potential functional roles of transposons remains challenging owing to their evolutionary path, as well as their repetitive nature, which requires the development of specialized analytical tools. In this special issue, we present a collection of articles that lay out current paradigms in the field and discuss a vision for future research. This article is part of a discussion meeting issue 'Crossroads between transposons and gene regulation'.
