The RNA G-quadruplex (rG4) is a kind of non-canonical high-order secondary structure with important biological functions and is enriched in untranslated regions (UTRs) of protein-coding genes. However, how rG4 structures evolve is largely unknown. Here, we systematically investigated the evolution of RNA sequences around UTR rG4 structures in 5 eukaryotic organisms. We found universal selection on UTR sequences, which facilitated rG4 formation in all the organisms that we analyzed. While G-rich sequences were preferred in the rG
