A tale of two dead ends: origin of a potential new gene and a potential new transposable element
Abstract
An article in this issue of Molecular Microbiology by Cultrone et al. describes how a non-autonomous helitron element could arise from its autonomous parent transposon by deletion followed by readthrough into an adjacent gene and its promoter, thus providing a mechanism for distribution of a specifically regulated promoter sequence around the genome, where it would have the potential to evolve new functions.
